Abstract: A great deal of the pollutants have been produced by the civilized human by virtue of his input into industries and consequently the output being the release of pollutants into the aquatic ecosystem. Scientific studies confirm that different pollutants have varied impacts on the aquatic biota and in particular fishery resources that form a food resource to human. Thus it becomes increasingly apparent that industrialization and other multifaceted activities of human have caused aquatic pollution. India is one of the largest fish producing nations in the world ranking ninth among other nations. Almost all the pollutants interfere with the metabolism of the aquatic fauna including fish fauna. Pollutants exhibit lethality that is diversified in various organ systems. Respiratory changes include clogging of the gills due to the modification of bronchial cells by histopathological changes, whereas damage to haemopoietic tissue can lead to modification of the respiratory pigments of the blood and can decrease the oxyphoretic capacity of the blood. Generally the pollutants percolate into the cellular level through the cell membrane and interact with cellular macromolecules to inhibit the essential cellular metabolism. Thus, measurement of sublethal responses at the cellular level could provide an insight for an assessment of water quality and environmental impact of pollutants. The present case study investigations discloses not only the effluents which cause imbalance in the brackish water ecosystem and shrimp inhabitation but also throws light on the effect of human health through the aquatic food chain.

Abstract: Shrimp farming is a rapidly growing and economically attractive industry in many tropical nations. In India, many shrimp farms mushroomed haphazardly all along the coast. Production of shrimp is often limited by deterioration of water quality, as discharge from aquafarms ultimately reach the receiving waters such as rivers, creeks, estuaries and sea or land. Shrimp farms are generally developed in groups and in certain locations the inlet from one farm receives water from the outlet of nearby farm. When compared to other industries, pollution from aquaculture is negligible and its source is the nitrogenous excretory wastes of the cultured organisms, which may cause eutrophication in marine/estuarine systems. A case study was undertaken in Kandaleru creek area in Nellore District of Andhra Pradesh, India in order to assess the nutrient release in terms of nitrogen, due to large scale shrimp farming and its impact on the creek evaluated. The changes in nitrogen levels are quite high and show a marked risk of eutrophication in the creek when semi-intensive shrimp farming is practiced in the area.

Abstract: India is endowed with rich and diverse inland water resources in the form of rivers, canals, estuaries, lagoons, backwaters, brackishwater impoundments, mangroves, floodplain wetlands, upland lakes, swamps and man-made reservoirs, tanks and ponds. Since the country's marine fishery sector is not expected to grow much, most of the shortfall must be met essentially from inland fisheries. West Bengal has more than 150 beels covering an area of 42,000 ha, constituting 22% of the total freshwater area of the state. The findings are presented of a study conducted to investigate the fisheries of some 20 beels in West Bengal. The following aspects are covered: ecosystem oriented fishery management; detrital dynamics; capture fisheries; culture-based fisheries; and fishery options.

Abstract: Mangrove ecosystems are peculiar formations occurring in sheltered tropical, coastal and estuarine areas. These waters contain a lot of organic matter, which is degraded by bacteria and fungi through a process of mineralization. The aerobic and anaerobic heterotrophic microorganisms grow and exhibit strong hydrolytic activity such as proteolytic and cellulolytic activity and the autotrophs also show oxidation and reduction of compounds of iron and sulfur. Such nutrient cycling is very essential, in keeping the biotic process of mangroves going in continuous cycle in Nature. So far these facts were largely conjectural, based on piece meal data generated from various sources. To confirm this fact, the microorganisms aerobic as well as anaerobic were studied from two types of mangrove ecosystems: (1) Mining distributed environment of Goa (control). (2) Normal, healthy mangroves of Konkan. The physico-chemical factors, elemental analysis, total microbial flora-both aerobic and anaerobic, % dominance of aerobic bacterial sp., % incidence of autotrophic bacteria and their activities such as iron oxidation and reduction were studied and monitored over a period of time to prove many of the above conjectures. The beneficial activities of strong hydrolysis, iron reduction and oxidization could be fruitfully used to take care of certain problems in agriculture and mining disturbed areas, such as phosphate solubilization in soils, ion removal from bauxite and removal of tin using a microbial process. A case study in Thailand on tin removal is presented.

Abstract: The state of Goa located along the midwest coast of India, flanked between continuous range of rugged hills constituting the Western Ghats in the east and vast expanse of Arabian Sea on the west, is a traveler's delight. Until recently a popular destination for domestic and foreign conventional 'resort tourist', the state is now witnessing an upsurge in eco-tourism, which is a subset of wildlife or nature tourism. Being a coastal state, Goa enjoys a unique combination of nature's endowment, a significant component of which is the diversity of its coastal habitat characterized by a variety of landforms like beaches, estuaries, islands, lagoons etc. This entire range of coastal environment offers the most amazing array of biodiversity, an important natural resource for 'alternative tourism'. The Government of Goa is facilitating the diversification of tourism product from traditional 'leisure tourism' to 'green tourism'. This paper reviews the potential and prospects of marine eco-tourism in Goa with a special emphasis on mangrove ecosystem. An attempt has been made to present the SWOT analysis of the mangrove related eco-tourism enterprise such as backwater cruises, bird watching and crocodile safari of Cumbarjua canal. An attempt has also been made to verify the anecdotal proposition that eco-tourism is ecologically begin, by presenting a case study of mangroves swamps of Chorao, one of the largest Island at the mouth of river Mandovi and also the site of Goa's only protected Areas for birds, Dr. Salim Ali Bird Sanctuary. The issue of providing opportunities to understand cultural and natural history through eco-tourism is also highlighted by presenting a case study of "Mannge Thapnee" (crocodile worship), a unique folk religious response of some eco-tribes settled in this mangrove habitat. The paper is a balance sheet of costs and benefits of 'green consumerism' in the tourism sector.

Abstract: To study the influence of estuarine environment on Benthonic foraminifera, sediment samples and bottom water samples were collected at 9 stations in the Uppanar river estuary of Tamil Nadu. Out of 25 foraminiferal species identified, 7 are arenaceons agglutinated, 4 are calcareous imperforate and the remaining 14 are calcareous perforate. Detailed study on the distribution, diversity and ecology of these foraminifera was carried out. The study reveals that the first four sampling stations from the mouth are densely populated and have higher diversity of fauna. Ammonia tepida, and Quinqueloculina seminulam are the two widespread and abundant species and their distribution and ecology in the study area reveal that they have a positive correlation with salinity of bottom water and Calcium Carbonate and Organic matter contents of the sediments. Salinity is the main influencing parameter on the foraminiferal fauna in the estuary. Silty clay sand is considered to be the favourable substrate for the abundance of foraminiferal population.

Abstract: Vellapatti is a small fishing village in the southern part of Gulf of Mannar, situated 7 km north of Tuticorin town, Tamil Nadu, India. The people of this village solely depend on the coral reef ecosystem around Vaan and Koswari islands for their livelihood. The community facilities, fishing grounds, fishing methods, species composition in the landings, market structure and the socio-economic condition of the fisherfolk were assessed. The problems in resource utilization have been addressed and suggestions are given for conservation and sustainable utilization of resources.
