Das,-S.N.;Thakur,-R.S.-eds. NEW-DELHI-INDIA ALLIED 1997 pp. 168-172 LA: English ER: M (Marine) AB: The fresh subsurface peat samples were palynologically investigated from exposed sedimentary sections at Calcutta, Hooghly and Howrah. The dominant recovered types were Heritiera along with the some members of mangrove vegetation. The assemblege depicts existence of swampy halophytic vegetation about 7030 yrs. B.P. The migration of Sundarbans towards South was probably due to continued river silting and other associated physical and biotic factors. AN: 4034570 3 of 395 TI: Studies on mangrove ecosystem using remote sensing data AU: Prasad,-V.K.; Rajagopal,-T.; Soujanya,-Y.K.L.; Srinivas,-D.S.; Badarinath,-K.V.S.

Das,-S.N.;Thakur,-R.S.-eds. NEW-DELHI-INDIA ALLIED 1997 pp. 121-125 LA: English ER: M (Marine) AB: Ths studies related to mangrove ecosystem are important in the context of global warming and sea level rise. Satellite remote sensing data provides information on dynamics on land use changes and provides information on aspects related to biodiversity. In the present study, remote sensing data has been used to study land use dynamics, impacts due to sea level rise and species richness in parts of Guntur District, Andhara Pradesh, India. AN: 4034568 4 of 395 TI: Significance of peat on the western continental shelf of India AU: Mascarenhas,-A. AF: NIO, Dona Paula, Goa 403 004, India SO: J.-GEOL.-SOC.-INDIA 1997 vol. 49, no. 2, pp. 145-152 LA: English ER: M (Marine) AB: Peat layers 2 to 30 cm in thickness, 22 to 46 m below present sea level, are found along the inner shelf of India, up to 27 km from the coast. They are rich in plant debris, organic carbon and sulfur. These organic-rich layers are not sedimentary deposits. Lack of favourable substrates, absence of sheltered habitats, high energy physical environments, and a very rapid sea level rise during Early Holocene indicate an unfavourable paleogeography and adverse oceanographic conditions for mangrove development and in situ peat formation. On the contrary, significant siliciclastic minerals, lithogenous elements and type III kerogen suggest a continental origin of peat. Restricted thickness, limited lateral distribution, absence of matted structures and laminated deposition imply transport of organics. Anomalous ages of wood with respect to present sea level are evidences of sediment reworking. Hence, peats on the continental shelf are not transgressive deposits. AN: 4034548 5 of 395 TI: Remote sensing application for delineating coastal vegetation -- a case study AU: Kunte,-P.D.; Wagle,-B.G. AF: NIO, Dona Paula, Goa 403 004, India SO: CURR.-SCI. 1997 vol. 72, no. 4, pp. 239-241 LA: English ER: M (Marine) AB: Remote sensing data has been used for mapping coastal vegetation along the Goa Coast, India. The study envisages the use of digital image processing techniques for delineating geomorphic features and associated vegetation, including mangrove, along the central part of the Goa Coast which includes the Mandovi-Zuari estuaries complex. It is concluded from the study that (1) repetitive coverage and spatial resolution of space borne data permits us to locate recently deposited alluvium and change in vegetation (2) though constant biotic pressure is severely degrading the coastal vegetation, there are a few locations, where recent alluvium has deposited forming favourable grounds for growth of vegetation. AN: 4034546 6 of 395 TI: Aquaculture: A solution, or source of new problems? AU: Masood,-E. SO: NATURE 1997 vol. 386, no. 6621, p. 109 LA: English ER: M (Marine); F (Freshwater) AB: Until recently, aquaculture--the selective breeding and raising of fish in "fish farms"--promised to resolve problems caused by the world's growing shortfall in marine fish supplies. But increasing awareness of its unwanted side-effects means that aquaculture itself is also heading for troubled waters, particularly in the developing countries. Intensive fish farming in India and China, for example, the world's largest aquaculture producers, has led to pollution and the spread of disease. Evidence is also emerging that the promotion of aquaculture--84 per cent takes place in Asia--is causing significant unemployment among those engaged in traditional fishing. Last month, India's Supreme Court dismissed a call for a judicial review of a decision last December demanding the closure of virtually all commercial shrimp farms in five coastal states by 15 April, and the payment of compensation to employees made redundant. The decision includes a ban on all aquaculture in mangrove swamps, estuaries, wet-lands, and on public land, as well as a prohibition on converting agricultural land into shrimp farms. The court had ordered the closure after a long campaign by environmentalist groups protesting in particular at the contamination of land and drinking water from the discharge of toxic effluent.

Resour., Madurai Kamaraj Univ., Madurai - 625 021, India SO: J.-ENVIRON.-BIOL. 1996 vol. 17, no. 3, pp. 221-226 LA: English ER: M (Marine); B (Brackish) AB: The 96h LC sub(50) values of pollutants for the crab larvae (Nanosesarma batavicum, Neoepisesarma mederi, Heteropanope indica) were as follows: mercury from 15 to 33 ppb, cadmium 80 to 100 ppb, zinc 125 to 250 ppb and copper 52 to 150 ppb; pesticide- DDT 155 ppb, endosulphan 31 ppb and diesel oil 4% WSF. Using the safe concentration factor of 0.01, the allowable safe concentration for Cu, Cd and Zn were 0.52 ppb, 1.15 ppb, and 1.25 ppb respectively while no such recommendation can be made for Hg, pesticides and diesel oil. Based on the LC sub(50) values and derived safe concentration most of the test species appear to be safe at present levels of these pollutants at the Vellar Estuary and associated backwaters and mangroves. AN: 4005967 8 of 395 TI: Texture and geochemistry of the sediments of a tropical mangrove ecosystem, southwest coast of India AU: Badarudeen,-A.; Damodaran,-K.T.; Sajan,-K.; Padmalal,-D. AF: Cent. for Earth Sci. Stud., Thuruvikkal P.O., Trivandrum 695 031, India SO: ENVIRON.-GEOL. 1996 vol. 27, no. 3, pp. 164-169 LA: English ER: M (Marine); B (Brackish) AB: The textural and geochemical aspects of the sediments of a tropical mangrove ecosystem have been studied and discussed. The sediments are characterized by the abundance of silt and sand with minor amounts of clay. The mean size of the sediment ranges from 0.205 mm to 0.098 mm (fine to very fine grained sand). The sediments are very poorly sorted, negatively to very negatively skewed, and platy to extremely leptokurtic in nature. The organic carbon content of the sediments ranges from 0.33% to 4.93%, which is controlled by the particle size of the sediments. The CaCO sub(3) content is five times the enrichment of organic carbon. This enhanced CaCO sub(3) content of the mangrove sediments might be a result of the abundance of shell fragments in the sediments. The shell mining activities in the estuarine bed adjoining the Kumarakam mangroves also contribute a substantial amount of lime muds to the mangrove area, which in turn add CaCO sub(3) to the sediments. The relative concentrations of heavy metals are Fe > Mn > Cr > Zn > Ni > Cu. All heavy metals other than Fe show an increase in concentration compared to the other parts of the estuarine bed. Cluster analysis indicates that the contents of organic C, Fe and Mn have a marked bearing on the Cr, Zn, Ni, and Cu levels of the mangrove sediments. AN: 4004868 9 of 395 TI: Mangroves as indicators of coastal change AU: Blasco,-F.; Saenger,-P.; Janodet,-E. AF: Inst. for Intl. Map Vegetation, CNRS/Univ. Paul Sabatier, 13, Ave. du Colonel Roche, 31405 Toulouse Cedex, France SO: CATENA 1996 vol. 27, no. 3-4, pp. 167-178 LA: English ER: M (Marine) AB: In view of the unique biological characteristics of mangroves, it is interesting to assess the extent to which these ecosystems can be used as indicators of coastal change or sea-level rise. From recent studies of mangrove mortality at several locations (including Guiana, Gambia, Cote d'Ivoire, Kenya, India and Bangladesh), it appears that these coastal ecosystems are so specialized that any minor variation in their hydrological or tidal regimes causes noticeable mortality. Each species of mangrove (but particularly those belonging to the genera Rhizophora, Bruguiera, Sonneratia, Heritiera and Nypa) occurs in ecological conditions that approach its limit of tolerance with regard to salinity of the water and soil, as well as the inundation regime. If the duration of daily immersion were to be modified by tectonic, sedimentological or hydrological events, the species either readjusts to the new conditions or succumbs to unsuitable conditions. Consequently, the use of remote sensing data for mangrove ecosystems offers excellent potential as a tool for monitoring coastal change.

Coll., Darjeeling 734101, India SO: ENVIRON.-ECOL. 1995 vol. 13, no. 4, pp. 766-768 LA: English ER: M (Marine); B (Brackish); F (Freshwater) AB: The (Indian) Sundarbans is floristically poorer, due to higher salinity and human interference. It is imperative to conserve the ecosystem for maintaining ecological balance, for protecting inland areas and for commercial exploitation. Artificial regeneration in foreshore lands has been done by hand and aerial seeding. Species are selected on the basis of greater utilizable biomass but should actually be done with respect to conditions prevailing at the particular area. AN: 3999043 11 of 395 TI: Waterbirds and substrate quality of the Pichavaram wetlands, southern India AU: Nagarajan,-R.; Thiyagesan,-K. AF: Div. Wildl. Biol., A.V.C. Coll., Mannampandal 609 305, Mayiladuthurai, Tamil Nadu, India SO: IBIS 1996 vol. 138, no. 4, pp. 710-721 LA: English ER: B (Brackish) AB: The water and mud characteristics of the six types of wetlands in Pichavaram were compared in order to determine whether the habitat of waterbird species was characterized by them. Waterbird species richness was most influenced by mud phosphorus levels. Variation in water pH was the principal factor that determined waterbird diversity. The water level mainly determined the density of waterbirds. Levels of pH and nitrites in the water also appeared to influence significant variations in waterbird diversity and density, respectively. Bottom substrate variables, viz. pH and phosphorus levels, were also significantly correlated with the density and richness of waterbirds, respectively. Water quality factors, viz. pH and nitrite and mud pH and phosphorus, were correlated with the abundance, while water depth was correlated with the accessibility of prey to the birds.

COCHIN-INDIA CMFRI 1995 no. 61 pp. 117-122 ST: CMFRI-SPEC.-PUBL. no. 61 LA: English ER: M (Marine) AB: The microbial interrelationship in mangrove sediments was found out by constructing the ratio between bacteria and actinomycetes, bacteria and fungi and fungi and actinomycetes. In addition temperature, pH, salinity, dissolved oxygen and organic carbon were determined seasonally and their possible relationship was statistically analysed and the results are presented. Isolated actinomycetes were subjected to cross streak assay to know their nature of antibiotic activity against test fish pathogens and crude antibiotics were extracted from selected isolates. Also their inhibitory activity was studied and the results discussed. AN: 3983823 13 of 395 TI: The effect of heavy metals on the physiological changes of microalgae AU: Ithack,-E.; Gopinathan,-C.P. AF: CMFRI, Cochin-682 014, India CA: Central Marine Fisheries Research Inst., Cochin [India] SO: MARICULTURE-RESEARCH-THE-UNDER-POSTGRADUATE-PROGRAMME-IN-MARICULTURE-PART-6 Rengarajan,-K.-eds. COCHIN-INDIA CMFRI 1995 no. 61 pp. 45-52 ST: CMFRI-SPEC.-PUBL. no. 61 LA: English AB: Experiments were conducted to find out tolerence limit of a microalgae to Copper, Zinc and Lead. Effect of heavy metals on growth rate, primary production and chlorophyll content of microalgae are examined. The effect of heavy metals on natural phytoplankton populations collected from mangrove ecosystem and prawn culture ponds are studied. Toxicity of heavy metals have been studied and the results shows that Copper is the most toxic and Lead is the least toxic heavy metal to both microalgae and natural population of phytoplankton. Natural populations collected from mangrove ecosystem was found to be more tolerant compared to populations of prawn culture pond. The author concludes with a remark that for successful operation of hatchery system the seawater should have very low concentration of heavy metal i.e, below 5 ppm of copper, 30 ppm of zinc and 50 ppm of lead for rearing larvae.

MADRAS-INDIA AQUACULTURE-FOUNDATION-OF-INDIA pp. 72-83 LA: English AB: The importance of mangrove ecosystem of Sunderbans for its potential for fisheries and aquaculture is discussed. Distribution of mangroves and physiography are explained with state wise data. The location of Sunderbans, the species composition of flora and fauna of the ecosystem and their zonation pattern are given. Seasonal variations and the associated changes in the water quality, physical, chemical and biological parameters are discussed. Soil quality is considered with regard to its suitability for the construction of aquaculture farms. The factors responsible for the production of mangrove ecosystem are enumerated. The paper also includes suggestions for the successful management of aquaculture ponds in Sunderbans.

Botany, Utkal Univ., Vani Vihar, Bhubaneswar - 751 004, India SO: J.-ENVIRON.-BIOL. 1996 vol. 17, no. 4, pp. 325-330 LA: English ER: M (Marine); B (Brackish) AB: Studies on soil nitrogen transforming bacterial population of four different selected sites of Bhitarkanika mangrove forest reveal highest microbial population during winter and being lowest in rainy season. There is a gradual decrease in the bacterial population due to deforestation and adverse effect of increased salinity in deforested land and salty land respectively. Soil pH was found to be lower during summer and reaches to the peak during autumn. This is totally opposite with the case of soil organic carbon level. Soil available N sub(2) status of four different places showed a diverse effect, with season and is low in river bank soil, due to tidal flows. AN: 3980803 17 of 395 TI: Brackish water mosquito problem of Vypeen Island, Cochin, Kerala AU: Mariappan,-T.; Arunachalam,-N.; Reddy,-C.M.R.; Sabesan,-S.; Panicker,-K.N. AF: Vector Control Res. Cent., Pondicherry-605 006, India SO: SOUTHEAST-ASIAN-J.-TROP.-MED.-PUBLIC-HEALTH 1996 vol. 27, no. 1, pp. 145-148 LA: English ER: B (Brackish) AB: A preliminary study has shown that the marshy terrain and brackish water bodies associated with mangrove forests contributed profuse breeding of mosquitos in Vypeen island, causing a severe menace to the island population. A total of 14 species belonging to four genera viz, Aedes, Anopheles, Armigeres and Culex was recorded from different habitats. Culex sitiens was found to be the predominant mosquito in all the perennial breeding habitats. The extent of different habitats in the production of mosquitos, and its possible abatement, using environmental and/or biocontrol methods are discussed.

AF: Department of Zoology, British Museum (Natural History), London SW7 5BD, UK SO: J.-MOLLUSC.-STUD. 1986 vol. 52, no. 3, pp. 225-242 LA: English ER: M (Marine); B (Brackish) AB: On the basis of reproductive anatomy and radula, the poorly known genus Mainwaringia Nevill, 1885, is shown to belong to the Littorinidae. The genus is represented by two species, M. leithii (E.A. Smith, 1876) from India to Vietnam, and a new species, M. rhizophila, from Malaysia to Hong Kong. Both occur in mangrove forests. The reproductive anatomy of M. rhizophila is described in detail, and it is interpreted as a protandrous hermaphrodite, a condition unique in the Littorinacea. In the intersexual and female stages both closed pallial oviduct and open prostate are present in the mantle wall, suggesting that these structures are not strictly homologous. The affinities of Mainwaringia are discussed, and it is concluded that it may be most closely related to Littorina s.s (DBO).

A coordinated attempt has been made to classify and interpret total organic matter (TOM) in relation to the depositional environment. Organodebris analysis dated back to ca 3,200 years B.P. has provided clues that ponding environment gave rise to reducing (anaerobic) conditions which probably accelerated microbial activity, transforming the palynodebris into first semi-amorphous/amorphous and then into fine organic matter. Various phases of mangrove vegetation development, the factors responsible for degrading mangals and land denudation have also been discussed in the light of multivariate methods of data analysis.

Higher salinity led to an increase in the amino acid pool size and the number of amino acids produced. Acidic amino acids were present in higher concentrations at 6.9 ppt and 20.7 ppt salinities. Gln, His, Thr, Arg and Val were present only when the fungus was exposed to high salinity conditions. The concentration of Gly increased with salinity. Arginine and ornithine were present in low salinity, but in high concentrations at higher salinities. Proline and Dragendorff-positive compounds were absent.

(Particoma) nairi the Pholadidae and Sphaeroma terebrans, S. annandalei of the Sphaeromatidae were the species active in the area. The most destructive group was sphaeromatids forming as much as 85.4%. Maximum incidence of L. pedicellatus was noted towards the low saline areas while D. manni and T. furcifera exhibited a different raction preferring area around the bar-mouth where the salinity was maximum, the former attacking even live mangroves. M. (P.) nairi and S. terebrans were very common both exhibiting tolerance to wide ranges of salinity. It was observed that different species effectively avoided competition and thus shared the limited wood substratum available in the estuary through their salinity preperences.

The number of fungi recorded on prop roots (44) were much greater when compared with seedling (18) and wood (16). Each substrate had its own common, frequent and occasional fungi appearing on them. The most common and abundant fungus on wood was Lophiostoma mangrovei. Verruculina enalia was most common on prop roots and seedlings. Some of the fungi were found to occur on all the three substrates, but their frequency and percentage occurrence on individual substrates varied. Halocyphina villosa, the lone Basidiomycete recorded was more abundant on seedlings, while Monodictys pelagica showed relatively high occurrence on wood and the least on seedlings.

The pollen are distributed up to 123 km offshore. With the increase in offshore distance, the quantity and quality of pollen decrease proportionately. Pollen spectra show that amongst the mangroves, rhizophoraceous pollen are overrepresented as compared to their presence on the corresponding coasts. The tropical plants, viz., Terminalia, Sapotaceae, Caryota, Anacardiaceae and Acacia, etc. are fairly well represented. Overall dominance of non-arboreals over the arboreals is recorded in the pollen spectra. AN: 3956086 31 of 395 TI: Treasured islands!

These values were found to decrease with the maturity of leaves and minimum values were found in the detritus. Crude fibre content showed an opposite trend, organic carbon content decreased from tender to withered form of leaves, but increased in the detritus. Protein and moisture content were higher in Excoecaria as compared to Ceriops. Detritus of these two species did not show any significant qualitative variation. It was found that full grown leaves could be used, instead of natural withering of leaves, to decompose and enrich the nutrient quality of water.

In January 1993 I visited mangroves on two islands in the south-eastern part of the Delta area of Bangladesh. In that region, chars are low-lying islands composed of consolidated silt, often peopled by a community living by fishing and cultivation. Mangroves were examined on two of these which lie south of the island referred to as Dakhin Shahbaz in the Times Atlas, namely Dhal Char and Char Kukrimukri. In both places the predominant mangrove trees were Sonneratia apetala. At Char Kukrimukri Pythia plicata (Ferussac, 1821) occurs, a pulmonate in the superfamily Ellobioidea, with a distribution at least from Sri Lanka to the east coast of Thailand, including the Delta region and the Andaman islands. A sample was collected from the leaves of A. ilicifolia and E. agallocha. Individuals were present singly on leaves 1 to 2 m above the ground, a few per bush, with gaps between occupied bushes. The snails had been feeding and were partially emerged and active; soil on their shells indicated that they sometimes descend to and burrow in the ground.

Total chlorophyll content varied from 0.21% in A. cucullata and C. decandra to 0.56% in A. corniculatum. Calculated chlorophyll a:b ratio was the minimum (1.55) in A. officinalis and the maximum (3.50) in B. sexangula. The carotenoids also varied from 0.04% in B. sexangula to 0.17% in A. corniculatum. Analysis of Variance showed intra- and interspecific variations in photosynthetic activities. TAN values revealed appreciable variations from 20.00 to 45.00 in A. officinalis and H. littoralis respectively. TAN values showed negative correlation with chlorophyll b and carotenoids, but highly significant positive correlation was noted with chlorophyll a:b ratio among the species. Total leaf protein content significantly varied from 12.21% in H. macrophylla to 29.22% in H. fomes. The quantitative analysis of tannin and polyphenols from the leaves of mangroves showed significant variation, 8.39% to 44.27% in A. cucullata and B.sexangula and 11.39% to 52.89% in A. officinalis and C. decandra respectively.

Dehadrai,-P.V.;Das,-P.;Verma,-S.R.-eds. MUZAFFARNAGAR-INDIA NATURE-CONSERVATORS 1994 pp. 271-295 LA: English ER: M (Marine) AB: With intensification of fishing in the inshore regions of the Indian Seas for increasing marine fish production through several innovations, a number of fisheries resources have come to be exploited at optimum levels. The demand for fish and fish products both for internal consumption and for export, has been the main reason for this situation. Among finfishes, the whale shark Rhiniodon typus of Gujarat, the catfishes of the genus Tachysurus off Karnataka and the whitefish Lactarius lactarius along the south-west coast of India have been reduced in abundance. The once existing fisheries for "Dara" Polynemus indicus, P. heptadactylus, "Karkara" Pomadasys hasta, "Koth" Otolithoides brunneus, "Ghol" Protonibea diacanthus, "Wam" Congresox talabanoides, Muraenesox cinereus, all of the Gujarat - Maharashtra coast and for Platycephalus maculipinna along the south-east and south-west coasts have become nonexistant at present. The other marine animals which are causing concern because of habitat damage or declining populations are the corals in the Gulf of Manner, Palk Bay, Gulf of Kutch and the Lakshadweep and Andaman-Nicobar Island systems; the gorgonids in the Gulf of Manner, the molluscan top shells Trochus and Turbo in Andaman-Nicobar Islands; the sacred chank and the pearl oyster Pinctada fucata along the south-east coast; the spiny lobsters Panulirus spp. off southeast and southwest coasts and the deep sea lobsters off southeast coasts and southwest coasts; the robber crab Birqus latro in Andaman Islands; the sea cucumbers in the Gulf of Manner, Palk Bay and the two island systems; the king crab Tachypleus gigas of the West Bengal - Orissa coasts; the sea turtles Chelonia, Eretmochelys, etc and the sea cow Dugong dugon in the Gulf of Manner and Palk Bay. The two marine ecosystems of coral reefs and the mangroves which harbour a wide variety of finfishes, crustaceans and molluscs of commercial value among different parts of the coast and the islands have reached a vulnerable stage. Besides, the ceaseless bottom trawling operations within about 50 m depth from the coast of as well as pollution of coastal waters in certain places have been damaging the habitats, thus leading to various ecological problems. Suggestions are offered for the conservation and rational exploitation of marine resources through stricter enforcement of existing laws, setting up of sancturies and reserves, diversification of fishing, declaration of closed seasons for fishing and extension education for coastal human population.

MUZAFFARNAGAR-INDIA NATURE-CONSERVATORS 1994 pp. 261-269 LA: English ER: B (Brackish) AB: Intensive survey of ichthyofauna for over 4 years from a South Indian mangrove ecosystem revealed the occurrence of 197 typical brackishwater elements and a few freshwater species. Of these, 33 species were categorised as rare elements. They belong to the families Dasyatidae (1 sp.), Clupeidae (1 Sp), Dorosomidae (1 Sp), Ariidae (1 Sp), Syngnathidae (1 Sp), Scorpaenidae (3 Spp), Serranidae (3 Spp), Echeneidae (1 Sp), Lutjanidae (3 Spp), Lobotidae (1 Sp), Pomadasyidae (1 Sp), Sparidae (1 Sp), Blennidae (1 Sp), Callionymidae (1 Sp), Gobiidae (4 Spp), Periophthalmidae (1 Sp), Taenioididae (1 Sp), Trypauchenidae (1 Sp), Acanthuridae (1 Sp), Soleidae (2 Spp) and Cynoglossidae (1 Sp). Interestingly most of the rare species encountered were marine juveniles. Besides, one species belonging to the family Periophthalmidae (Periophthalmus koelreuteri (Pallas)) recorded just a decade ago is not available now in the South Indian mangroves. The reasons for the rare occurrence of certain selected species of ichthyofauna is the mangrove waterways are complex and diverse. A single factor or collective factors could be responsible for the rarity of individual species. Some of the factors discussed in the paper include the following: 1. Species richness in tropical regions makes certain species rare based on their poor genetic capability in the 'arena' of survival of the fittest. 2. Biotic control through predator-prey relationship and restricted feeding behaviour lead to rarity of certain species. 3. Zoogeography related factors such as restricted distribution, wider-distribution with preferential mass migration to certain selected localities and sporadic distribution to less conducive biotopes can also cause rarity of species in certain locations/open ecosystems. 4. Environmental variables in the dynamic brackishwater mangrove ecosystem and the capacity of individual species and size groups to tolerate/adjust to such fluctuating parameters lead to rarity of species. 5. Man made barriers and their adverse impact on the inherent behaviour and biological cycles of the species lead to rare occurrence of certain species. 6. Avoidance of certain small sized species to traditional gears and escaping mechanisms of certain other species by burrowing and hiding in the oyster reefs, prop roots of mangrove vegetation, algal mats etc. push certain species to 'rare' category besides biased sampling. 7. Unfavourable situations in breeding grounds of various species (including hydrobiological, climatological, biota related and anthropic factors) and the subsequent poor survival of the recruiting stock make the fish species rare in the natural systems. 8. Facultative utilization of mangrove waterways by certain marine juvenile fish species can cause rarity of species in the system. 9. Barriers and shelters (e.g., coral reefs) could make a nongregarious and nonparental care species sporadic in the mangrove ecosystem. 10. The demographic pressure, pollution by domestic wastes, indiscriminate over fishing, destructive fishing of undersized and felling of mangrove vegetation could affect the ecological stability and equilibrium of the fragile ecosystem and ultimately result in recruitment failure and rarity of species.

The huge organic detritus of the forest attracts a complex of faunal assemblage in search of food and shelter along with the ingress of tidal water. Commercial fishing at this area starts from August and continues up to late February every year. Though 92 fish species have been reported from this area, 25 fish species are listed as commercially important. Due to commissioning of Farakka Barrage in 1975 a great change has taken place in the faunal structure and abiotic features of the rivers. Based on personal interview, fish landing data and available records, a declining trend has been observed on the availability of some fish species. A list, thus prepared indicated 9 endangered, 8 vulnerable and 4 rare species from the area.

Thus the mangrove ecosystem sustains tremendous fishery resources. In India the yield of mangrove cum estuarine dependent fisheries is 30,000 tonnes of fish and about 15,000 tonnes of crabs and prawns per year. Crustaceans like Penaeus monodon, P. indicus and fishes like Etroplus sp., mullets, etc are common in Indian mangroves. Conversion of mangroves for coconut and paddy cultivation along with setting of fish ponds is an age old practice in coastal India and is called as 'filtration' or 'trapping'. The brackish water aquaculture covers an area of 45,000 hectare are produced. The species cultivated are mugil cephalus, Chanon-Chanos, Penaeus Monodon, P. indicus, Macrobrachium, etc. About 32.13% of this area is along west coast and the yield rate is about 500-600 kg/ha/yr. Some of the impacts of conversion of mangrove ecosystem for aquaculture purposes are discussed in the present paper. Finally, it is suggested to strictly implement some legislation, recently introduced by Ministry of Environment and Forest for the conservation of coastal zones such as mangroves.

These inputs formed major elements for preparing coastal zone management plans. IRS-1C data having improved spatial resolution (5.6 m PAN data), extended spectral range (inclusion of middle infra-red band in LISS-III) and increased repetitivity (5 days for WiFS data) have opened up new vistas of applications in the coastal zone. Preliminary analysis of IRS-1C data indicates that coral reef zonation, identification of tree and shrub mangroves, seaweed/sea grass beds, improved delineation of coastal features such as fringe mangroves, mudflats, beach, dune vegetation, saline areas, etc. as well as better understanding of suspended sediment patterns are now possible. These additional information will certainly form vital remote-sensing-based input for preparing coastal zone management plans.

This is accomplished by constructing what are called diversity indices and by studying their behaviour in relation to hydrographic parameters. Diversity indices are statistical tools for analysing ecological patterns and this help to understand, in a given community, how many species or groups are there and what are their relative abundance and how many are rare and how many are common. Diversity is composed of two components, the total number of species or groups and how the abundance of data are distributed among the species. The number of species in the community is often termed as 'species richness' by ecologists. The second component is species evenness on the equitable distribution of the species or gruops to the total population. Indices that attempt to combine both richness and evenness into a single value are refered as diversity indices.

Hence it is quite possible that the substratum where most penaeids remain burried during the day, affords these prawn a comparatively better range of environmental condition particularly salinity that helps them to survive and grow. The present investigation aims at comparing the interstitial water of the substratum with the column water as regards the parameters - salinity, temperature, pH, nitrate and nitrite. Besides, growth studies were simultaneously conducted in 4 pens erected in the culture pond by growing the juveniles of Penaeus indicus in them.

COCHIN-INDIA CMFRI 1993 vol. 53 pp. 39-47 ST: CMFRI-SPEC.-PUBL. vol. 53 LA: English ER: B (Brackish) AB: Mangroves are characteristic coastal vegetation and the community of tree and shrub along with faunal communities drawn from the adjoining estuaries and terrestrial system, form distinct specialised ecosystem. Apart from wood, timber and other produce of forest, the mangroves has been much valued as shore protectors, desalination agents, their high productivity and transport of organic food to other systems and capacity to recycle organic matter. From the fisheries point of view mangrove creeks and swamps form important nursery grounds for fishes and prawns. In the Cochin mangrove system Acanthus ilicifolius forms the predominant vegetation and have colonised traditional aquaculture fields and areas potentially suitable for such practices. Realising this importance and significance to coastal aquaculture, a study was undertaken especially to understand the different factors responsible for the colonisation, differential distribution, etc. of A. ilicifolius in the sea accreted areas of Vypeen Island. A study on the germination requirement of the species too is attempted. AN: 3880282 52 of 395 TI: Studies on rhizosphere microflora of Acanthus ilicifolius AU: Raman,-M.; Chandrika,-V.

COCHIN-INDIA CMFRI 1993 vol. 53 pp. 87-95 ST: CMFRI-SPEC.-PUBL. vol. 53 LA: English ER: M (Marine) AB: Feed forms the major operational input and greatly influences the running expenditure of prawn culture operations. Therefore, formulation and supply of nutritionally adequate practical feeds, either complete or supplementary, become essential for the success of prawn culture. A number of compounded feeds have been developed for juveniles of Indian penaeid prawns with a variety of conventional feed ingredients. However, with the growth and expansion of aquaculture industry in India, shortage of these conventional feed ingredients can be expected as most of these ingredients are already being used extensively for the formulation of feeds for animal husbandry. Keeping this in view, research has been intensified at the Centre of Advanced Studies in Mariculture, CMFRI, Cochin to develop practical feed formulation using cheap nonconventional feed ingredients for extensive prawn culture.

Two contrasting coastal environments are prevailing in the area, namely: (i) the macrotidal Hooghly Estuary in the east; and (ii) the mesotidal Midnapore Coastal plain to the west. A morphogenetic study based on the terrain mapping unit (TMU) concept reveals the form-process-material interactions of these two contrasting coastal environments with a possible geo-history model of the coastal Quaternaries. It has been established that the entire process-response system of the coastal tract of the Bengal plain started operating after the rise of sea level around 6000yrs B.P. (i.e., optimum of Flandrain trangression). In the Midnapore coastal plain, the development of successive rows of dunes with intervening clayey tidal flats, is due to the punctuations in the regression of the sea during the Holocene times. Whereas, in the Hooghly Estuary, the mangrove vegetation plays a significant role as the dominant geomorphic agent in the evolution of the tidal shoals and their eventual accretion to the main landmass resulting in delta progradation. In the present-day scenario, the Hooghly Estuary becomes the abandoned part of the Ganga-Brahmaputra Delta in India, and is also turning destructive. An erosional regime is also prevailing in the western part of the Midnapore coastal plain. AN: 3880222 57 of 395 TI: Marine fungi from India - 6 AU: Borse,-B.D. AF: Dep. Bot., Arts, Commerce Sci.

Year round incursions with a maximum during the warmer months of December to March were observed. February to March is considered as the peak recruitment period. Out of six species of penaeids represented in the area, Penaeus latisulcatus (75%) and Penaeus indicus (15%) were dominant. The recruitment pattern indicated greatest incursions of post-larvae with the flood spring tides of the night when the tidal flow is strong. The juvenile population of P. latisulcatus is distributed in those intertidal sandflats with a rich growth of seagrass and P. indicus in the muddy areas of mangrove forests. P. indicus showed affinity for euryhaline conditions, whereas P. latisulcatus showed no preference for lower salinity. Provision of food and shelter are considered as important factors for their nursery dependence. P. latisulcatus attained a size of 60-70 mm in five to six months and P indicus 110-120 mm in six to eight months during their nursery phase. These juvenile penaeids were found to be omnivorous, feeding on animal products, plant material and detritus. The maturing P. latisulcatus emigrate back to the sea when they are about 65 mm, whereas P. indicus move out at about 120 mm. A positive correlation between post-larval recruitment and juvenile abundance was observed. (DBO) AN: 3877685 60 of 395 TI: Thraustochytrid and fungal component of marine detritus. 3.

Three phases were observed. (1) Thraustochytrids and the fungi Cladosporium herbarum and Halophytophthora vesicula colonised detritus during the first week, characterised by a rapid loss of detrital dry weight and a reduction in proteins, carbohydrates, reducing sugars, phenolics and cellulose. (2) Decline of most of the organic constituents in detritus to almost the lowest observed levels within 21 d was accompanied by an increase in fungal and bacterial biomass. Fungi and bacteria together contributed maxima of 0.052 and 0.065% to dry weight of 21 and 35 d detritus respectively. Protein values never increased with decomposition and microbial biomass buildup, although C:N values declined. (3) Total fungal and bacterial biomass decreased after 3 and 5 wk, respectively. However, thraustochytrids and marine fungal species such as Cirrenalia basiminuta and 'Hyphomycete XVII' attained high densities by 56 to 60 d. Most of the species present initially in the detritus were observed even in the last stages of decomposition examined (56 to 60 d). Thraustochytrids and fungi were isolated both from surface-sterilized and untreated detritus, suggesting epi- and endobiontic modes of life. Distinct sequences of fungal and thraustochytrid colonisation, presence of high fungal biomass relative to bacterial biomass, the high densities of thraustochytrids and accompanying biochemical changes indicate the importance of these organisms in the mangrove detrital processes.

Botany, Ramakrishna Mission Vivekananda Coll., Madras 600 004, India SO: BOT.-MAR. 1995 vol. 38, no. 5, pp. 413-416 LA: English ER: M (Marine) AB: An alkali extraction procedure yielded a dark brown pigment from the vegetative hyphae of the mangrove fungus, Cirrenalia pygmea. This pigment responded positively for all the diagnostic tests for melanin. The absorption spectrum of the pigment showed a strong absorption in the UV region with no absorption peaks in the visible region of the spectrum. A plot of log absorbance versus wavelength gave a linear curve with negative slope. The IR spectrum showed characteristic absorption bands. When tricyclazole, a specific inhibitor of dihydroxynaphthalene (DHN) type of melanin was incorporated in the growth medium, the fungus produced light coloured hyphae which were highly susceptible to osmotic shock. It appears that melanization of hyphae may afford protection to some marine fungi against sudden changes in osmotic pressure.

Whereas the mangroves are relatively well documented, very little is known about the other wetlands, with few exceptions. Only recently an inventory of these wetlands has been prepared but no effort has been made to classify them. A vast majority of the inland wetlands are temporary and/or man-made, and they have been traditionally used and managed by the local human populations. In this paper, first, we evaluate the classification schemes of the IUCN, US Fish and Wildlife Services and those of the Australian wetlands, for their applicability to Indian wetlands. Then, we propose a simple hierarchical classification of wetlands based on their location (coastal or inland), salinity (saline or freshwater) physiognomy (herbaceous or woody), duration of flooding (permanent or seasonal) and the growth forms of the dominant vegetation. We stress upon the hydrological factors which determine all the structural and functional characteristics of the wetlands. We consider that the various growth forms of wetland vegetation integrate the totality of hydrological variables and therefore, can be used as the indicators of different hydrological regimes.

Two of the reef modules are located very close to mangrove and estuarine areas, and are therefore prone to high turbidity. This could play a negative role on the sealife dwelling near them. The third module is dominated by seawater intrusion and thus has more marine conditions, relatively clear water and less suspended solids. The results thus indicate that the conditions of the first 2 modules do not favour colonization and aggregation of various organisms of commercial value, although nutritional enrichment of the water was evident. The third reef module appears to have environmental conditions that were more favourable for the objectives of the artificial reefs. The presence of artificial reefs does not seem to affect the natural environmental conditions in any significant way.

Experiments were also conducted to determine the effect of environmental factors on the growth and bacteriochlorophyll-a synthesis of this species. This strain showed the maximum growth in 30 x 10 super(-3) of salinity. The bacteriochlorophyll-a synthesis was maximum at the salinity 20 x 10 super(-3). The pH 7.5 was found optimum for bacteriochlorophyll-a synthesis and growth. This strain could grow in sodium sulphide concentrations between 0.02 and 0.1% (w/v) (optimum at the concentration of 0.08% (w/v)). Besides these, 0.15% (w/v) amonium chloride concentration also enhanced the synthesis of bacteriochlorophyll-a. The growth was inhibited when ammonium chloride exceeded 0.15% (w/v) concentration. It was also observed that this bacterium used various carbon and nitrogen compounds for its growth.

The occurrence of carbonized wood in widely spread offshore areas probably represents a regional transgressive event in the west coast which resulted in submergence and destruction of coastal mangroves. The rate of sedimentation in the study area varies between 0.12 and 0.37 mm/yr, much lower than those reported from shelf areas north of Mangalore. The slow accumulation of sediments in the southern parts of the western continental shelf of India, as exemplified from the present study, may be due to very poor discharge and low bed load sediments of the west-flowing small rivers of this part of the peninsula and low concentration of suspended particulate matter in them. AN: 3814848 73 of 395 TI: Processes which control the distribution of radium and uranium in the Ganges-Brahmaputra delta and their fluxes to the Bay of Bengal AU: Carroll,-J. CA: South Carolina Univ., Columbia (USA) SO: DISS.-ABST.-INT.-PT.-B-SCI.-and-ENG. 1991 vol. 51, no. 8, 158 pp NT: Diss. Ph.D.: Order No.: DA9101446. LA: English ER: B (Brackish) AB: The distribution of uranium and radium isotopes between sediments and seawater was investigated in two major areas of the Ganges-Brahmaputra (G-B) estuarine mixing zone. To the east of the main river channel is a shallow area (<7m)(2.5 x 10 super(3) km super(2)) containing several large islands and numerous small ephemeral islands which appear and disappear with tides and storms. To the west of the main river channel is a large mangrove forest (2.8 x 10 super(4) km super(2)). In January 1987, freshwater and sediment discharge were low (fw = 7600 m super(3)/s and sed = 5.4 x 10 super(9) kg/month). Mixing profiles show that radium was released from sediments to seawater. Radium activities in the mixing zone were greater than river and ocean endmember activities by 30-50 dpm/100L for super(226)Ra and 50-100 dpm/100L for super(228)Ra. These excess activities were supplied from suspended riverine sediment and sediments in the mangrove forest exposed to seawater for the first time, and by erosion of island sediments in the eastern delta. Additional super(228)Ra was supplied from nearshore bottom sediments during resuspension by tidal and wave action. Increased river discharge caused the mixing zone to migrate offshore from coastal sediment deposits. Desorption of super(226)Ra from suspended sediments discharged by the Rivers increased super(226)Ra activities in the 0-10ppt region of the mixing zone. In October 1987, dissolved super(226)Ra activities were a factor of 3-5 lower than in January as a result of lower water residence times and limited salt water exposure of nearshore sediment deposits. For the G-B mixing zone, sediment supplies from the Rivers and salt water migration into the western and eastern delta determine dissolved radium fluxes to the Bay of Bengal. The flux of super(226)Ra = 8 to 11 x 10 super(14) dpm/yr and the flux of super(228)Ra = 12 to 16 x 10 super(14) dpm/yr. These fluxes are not significantly different from flux estimates determined by the annual sediment discharge multiplied by radium which desorbed from river sediment and island sediment exposed to seawater for the first time. A mixing profile of uranium and salinity during low discharge in January 1987 shows uranium activities in waters <12ppt salinity are 20% lower than the predicted activity based on conservative mixing of river and ocean waters. These observations imply dissolved uranium is removed to sediments in the Ganges-Brahmaputra Delta. Tides and lower river discharge in the Delta prolong the association of nearshore sediments and low salinity water. Possible explanations for removal of uranium include removal of uranium to suspended sediments and adsorption of uranium to organic-rich sediments in the mangrove forest.

A detailed study on the hydrobiocoenology of the mangrove ecosystem of Muthupet (Kaveri river basin) Tamil Nadu, India, was undertaken. The present paper outlines the results of investigation on the distribution of mangrove plants in the Muthupet mangrove in relation to the chemical characteristics of the soil with reference to a few important trace metals. An attempt has also been made to measure some of the ecological parameters used in species zonation. The range of electrical conductivity of the estuarine soil ranged from 1.65 to 7.10 (m. mhos/cm) and the pH of soil ranged from 6.3 to 8.08. The concentration of nitrogen and phosphorus in the forest and in the mud flat has also been analyzed. A distinct zonation pattern, in the mangrove community, has been linked with the variation in edaphic factors, which are usually associated with the degree of tidal influence.

Monthly samplings were made from January to December 1989, covering three stations. For tintinnids, density varied from 60 to 44,990 org./m super(3). Agglomerated tintinnids were the dominant form. The maximum abundance (80,740 org./m super(3)) of copepods was recorded in the freshwater and neritic water mixing zone (station 2) during summer and the lowest (80 org./m super(3)) in the freshwater zone (station 1). The genera Acartia and Acrocalanus (belonging to the suborder Calanoida), Macrosetella and Euterpina (belonging to the Harpacticoida), and Oithona (belonging to the Cyclopoida) were coincident with the maximum species abundance at station 2. Species like Acartia southwellii and Oithona brevicornis were observed during the lower abundance period. Calanoid and harpacticoid copepods were also dominant at station 3. A significant positive relationship between the abundance of tintinnids and copepods was observed. The seasonal distribution and abundance of tintinnids and copepods are discussed in relation to hydrographical parameters.

Strong vertical gradients in the redox potential (Eh), interstitial water and sedimentary organic compounds were recorded. Microbial and phytobenthos also showed clear vertical gradients and a significant number of bacteria were encountered in the 15-20 cm depth. Abundance of meiofauna followed distinct vertical gradient and the number decreased significantly with increasing depth in the sediment. The reducing environment was characterised by high population of nematodes, turbellarians and harpacticoids. Meiofaunal taxa were significantly correlated with Eh and interstitial water of the sediment. Among the meiofaunal food, organic matter, ATP phytobenthic abundance and bacterial counts were positively correlated with meiofaunal density. Biochemical constituents did not yield any significant correlation with meiofauna. Food availability played a supporting role while physical environmental parameters were more important in meiofaunal dispersion in mangrove mud flats.

Principal forest formations inhabited by Sundarbans tigers have been described with vegetation types. Ecological dynamics of the plant-animal complex indicate strict protection of the habitat. The mangrove zone situated below the tide level was observed to be comparatively rich in generic and specific diversity over other zones which are frequently inundated. Salinity and tidal fluctuations in the mangrove swamps are the critical factors that regulate the physical and chemical environment of the entire biota. All other biotic and abiotic factors that exert considerable force on the environment have also been identified. Habitat formations like pure Cereops Excaecaria-Cereops which record high soil salinity also exhibit significantly higher human casualties from tiger. Soil salinity has been correlated with human casualties from tiger in different habitat formations types.

Varying levels of laccase activity were present in most of the fungi included in this study. The laccase plate assay was found to be much less reliable than the spectrophotometric laccase using the extracellular culture fluid of the fungal cultures grown in liquid media. Several factors including type of growth medium, growth medium pH, and assay pH had marked effects on laccase activity. A few strains produced high levels of laccase in both malt extract (ME) medium and low N medium; however, a majority of the strains produced laccase in low N medium (pH 4.5) but not in the ME medium. When grown in low N medium at pH 4.5, twelve of the strains showed acidic laccase (pH 4.5) activity; of these, seven also showed alkaline laccase (pH 8.2) activity. One of the strains exhibited laccase activity only when grown in the low N medium at pH 8.2. Lignin peroxidase (LIP) was not present in any of the strains tested, but three of the strains showed manganese-dependent peroxidase (MNP) activity. Xylanase and cellulase activities were observed in a majority of the fungi studied. The results indicate that laccase is widely distributed in fungi found on decaying lignocellulosic materials in the marine environment and that a number of these fungi also contain other lignocellulose modifying enzymes, except LIPs and MNPs which appear to be relatively less common in these marine fungi.

Borers occupy rhizomes as well as living and dead stems of Juncus roemerianus and other marsh species. More borers occupy exposed rhizomes than stems. Borers also inhibit peat. Borer population structure in a Juncus marsh is similar to that prop roots of nearby mangrove, Rhizophora mangle. Borer abundance in a receding marsh is significantly greater than in stable or accreting marshes. Borers may cause or exploit marsh recession, may be important regulators of marsh area and shape, and may also affect competition between marshes and mangroves where these wetlands overlap.

This station is also characterized by lower population density of polychaetes suggesting a predator-prey relationship. The abundance of sea anemones has been correlated with currents, salinity and sediment organic carbon but does not show any substrate specificity. Low sediment N/P ratios indicate domestic sewage pollution even though C/N ratios were lower due to less concentration of humic acid. Hence they can be treated as indicator of biofouling.

Among the eight commercially important species recorded, Penaeus indicus H. Milne Edwards, P. merguiensis De Man, P. monodon Fabricus and Metapenaeus dobsoni (Miers) were predominant. The postlarval recruitment size varied with species: P. indicus and P. merguiensis recruited at the size of 9-11 mm total length (TL), P. monodon at 12-14 mm TL and M. dobsoni at 4-6 mm TL. The species P. indicus, P. merguiensis and M. dobsoni were observed continuously throughout the study period with maximum abundance occurring from July to September in 1984-85 and from August through October in 1985-86. P. monodon occurred seasonally from November to January in both years. Postlarvae and juvenile catches were low during low salinity and high salinity periods and a higher density was observed in the months of moderate water salinity. Large numbers of P. indicus, P. merguiensis and M. dobsoni clearly showed the preference to the detritus rich muddy substrate, whereas P. monodon did not show any preference and was equally abundant over different substrate types.

Vierh. were studied. The GA sub(3) was found to enhance shoot growth by 26% and root growth by 40%, shoot dry weight by 145% at 50 mg/L. Indole-3-acetic acid also increased shoot dry weight by 139% and root length to 31% at 10 mg/L. The GA sub(3) was more effective than IAA in increasing the accumulation of protein, tissue nitrate, carotenoids, chlorophylls and their fractions in photosystems I and II and in the light harvesting complex.

LA: English ER: M (Marine) AB: The 480 km long coastline of Orissa extending over a greater part of Northwest Bay of Bengal is essentially a depositional environment endowed with six major estuaries, a rich mangrove belt, Asia's largest brackishwater lagoon (Chilka Lake), extensive non-vegetated wetlands and beaches rich in heavy minerals. This area is prone to cyclones and floods. Their effects and the implications of expected sea level rise on this coast are described. In the last two decades there has been increasing pressure on this coastal zone for the development of fishery, aquaculture, ports and harbours, defence facilities and urban settlements. Some of the developmental activities have given rise to environmental and socio-economic problems which have become issues of public concern and protest. This paper presents case studies involving some critical resources and habitats which illustrate the range of human activities in the area and the threats and constraint affecting sustainable development of the coastal zone. AN: 3693001 100 of 395 TI: Tolerance limits of two pulmonate snails Cassidula nucleus and Melampus ceylonicus from Pitchavaram mangroves AU: Dious,-S.R.J.; Kasinathan,-R. AF: CAS in Mar. Biol., Annamalai Univ., Portonovo 680502, India SO: ENVIRON.-ECOL. 1994 vol. 12, no. 4, pp. 845-849 LA: English ER: M (Marine); B (Brackish) AB: Tolerance as submergence coupled with salinity, temperature and desiccation experiments were conducted on Cassidula nucleus and Melampus ceylonicus in relation to their natural habitat. Both were highly active between 20 and 28 ppt salinity. Below and above these levels they showed different levels of decreased activities. Desiccation tolerance experiments confirmed that larger size group snails tolerate higher levels than smaller ones. The former was sensitive in the temperature range of 20-35 C and the latter of 20-38 C which are closely related to their natural environment. The limits lie close to the terrestrial habitat having the ability to withstand wide fluctuations in salinity, submergence, desiccation and temperature.

Laboratory studies on decomposition of leaves of the mangrove Rhizophora apiculata Blume AU: Raghukumar,-S.; Sharma,-S.; Raghukumar,-C.; Sathe-Pathak,-V.; Chandramohan,-D. AF: Biol. Oceangr. Div., Natl. Inst. Oceanogr., Dona Paula, Goa-403 004, India SO: J.-EXP.-MAR.-BIOL.-ECOL. 1994 vol. 183, no. 1, pp. 113-131 LA: English ER: B (Brackish) AB: The role of thraustochytrid protists and fungi in detrital dynamics of leaves of the mangrove Rhizophora apiculata was investigated in the laboratory. Field detritus of different ages (0, 4, 7, 14, 21, 28, 46, 53 and 60 days) obtained from litter-bag experiments were inoculated individually with five fungi, Cladosporium herbarum, Fusarium moniliforme, Cirrenalia basiminuta, "Hyphomycete XVII" and Halophytophthora vesicula and one thraustochytrid, Schizochytrium mangrovei. Biochemical changes occurring after 1 wk in 8 ages of detritus were examined. The results suggested two phases of fungal dynamics, the first corresponding to decompositional stages of 0-21 and the second of 28-60 days. Detrital material of the first phase supported better growth of the fungi Cladosporium herbarum, Fusarium moniliforme, Cirrenalia basiminuta and Halophytophthora vesicula. Cellulase production by all the test species, in general, was greatest on such detritus. Detritus of the second phase proved to be better for the growth of the fungus "Hyphomycete XVII" and production of xylanase by all test species. Pectic enzymes, amylase and protease were produced more or less uniformly in all ages of detritus. The thraustochytrid Schizochytrium mangrovei grew well on both phases of detritus. The test species utilised a wide variety of substrates as sole carbon sources but differed significantly in their capabilities to elaborate the various degradative enzymes in detritus. Fusarium moniliforme and Halophytophthora vesicula caused marked increases in detritus protein, while all the test species enhanced amino acid levels. Schizochytrium mangrovei enhanced carbohydrate and reducing sugar contents, while Fusarium moniliforme and Halophytophthora vesicula substantially decreased the levels of the former. Growth of Halophytophthora vesicula in detritus caused a decline of total phenolics. AN: 3644994 103 of 395 TI: Development of brackishwater prawn in Orissa--problems and prospects AU: Upadhyay,-A.S.

Natarajan,-P.;Jayaprakas,-V.-eds. THIRUVANANTHAPURAM-INDIA KERALA-UNIV. 1993 pp. 41-52 LA: English ER: B (Brackish) AB: Nature has gifted Orissa, India, with a coastline of 480 km and Chilka, the biggest brackishwater lagoon in India. There are 8 major river systems, with brackishwater areas, mangrove swamps, mud flats, salt marshes and salt pans. The total brackishwater resources in the state have been estimated to be nearly 0.3 million hectares. Out of the nearly 32,000 ha potential area identified for brackishwater aquaculture, around 22,000 ha have been reported to be suitable for prawn farming. The hydro-meteorological condition, soil properties, brackishwater parameters, availability of good quality prawn seeds in wild and socio-economic factors, provide much scope for developing scientific prawn farming in Orissa. However, the pace of development of prawn farming in this state is rather slow. This is mainly because of unnecessary delay in allotment of suitable land for farming, non-availability of good quality prawn feed, lack of technical manpower and inaccessibility to the potential sites in remote areas due to poor infrastructure.

Inst., Nagpur 440020, India SO: ENVIRON.-ECOL. 1994 vol. 12, no. 2, pp. 387-392 LA: English ER: M (Marine); B (Brackish) AB: Terrestrial flora and fauna of four aerated lagoon sites, namely Versova, Malad, Bhandup and Ghatkopar of Bombay coast were studied in 1990 prior to construction of lagoons. The sites represented six and 26 varieties of mangroves and avifauna respectively besides a large number of miscellaneous vegetations, invertebrates and vertebrates. Diversity, density, dominance and frequency of mangrove species revealed that Avicennia marina was most important species in these regions. However, density of Acanthus ilicifolius was higher at Versova. While considering vegetation cover, Ghatkopar emerged with highest score of cover abundance scale.

Among the algae only 16 species (30.19%) exhibited antiviral activity which includes 4 Chlorophyceae (Caulerpa racemosa, C. sertularioides, Codium adherens, Halimeda macroloba 4 phaeophyceae (Dictyota bartayresiana, D. dichotoma Sargassum tenerrimum, Zonaria crenata), and 8 Rhodophyceae (Centroceras clavulatum, Ceramium sp., Gelidiella acerosa, Gracilaria corticata, Hypnea musciformis, Laurencia obtusa, Laurencia papillosa, Polysiphonia sp). Ten mangroves (62.5%), Acanthus ilicifolius, Avicennia marina, Bruguiera cylindrica, Excoecaria agallocha, Rhizophora mucronata, R. lamarkii, Salicornia brachiata, Sesuvium portulacastum, Sueda maritima and S. monica. The present study reveals that only 37.68 of the marine plants contain antiviral principles, but the results of the total extracts (73) screened showed only 10.96% is effective for causing more than 50% inhibition on TMV. The red alga C. clavulatum and the seeds of the mangrove B. cylindrica and leaves of E. agallocha showed significant antiviral activity (>
