Aquaculture is also an important instrument for promotion of economic growth in developing countries and rural areas because it creates jobs, business and income.Aquaculture development within the Palk strait environment is currently hindered by a lack of information and knowledge relating to the impacts of large scale culture on open-coast locations, and also by general paucity of data relating to the Palk Strait region. This work endeavour to address these issues by overcoming the present uncertainities. Previous research indicates that the benthic environment is vulnerable to aquaculture development The overall goal of this study is to determine the impact of aquaculture based contaminants on the mussel Modiolus modiolus in the Palk Strait region.Hence it includes the following objectives Hydrographic conditions prevailing in Thondi and Karangadu coast with special reference to metal distribution in waterandsediment.Assessment of the impact of aquaculture pond effluents on metal accumulation in various soft tissues of Modiolus modiolus collected from Thondi and Karangadu.

The Molluscs constitute a significant part of world fauna today.The Palk bay area is familiar for the presence of economically important renewable resources like seaweeds, shrimps, lobsters, holothurians, mollusks and fin fishes.However there is lack of information on the molluscan fauna.The fauna is rich in the intertidal area and coastal habitats from Point Calimere to Mandapam .Of late coastal habitats here are under threat from development activities and over exploitation of natural resources. This necessitates documentation of fauna present in this important area besides categorizing them as endemic, threatened and endangered species. This exercise in addition to information on abundance and diversity will help in the earmarking areas for conservation. Therefore the present initiative was taken to prepare a checklist of bivalves species available here along with their classification and key characters for identification. From this Palk Bay area, we have identified and recorded as many as 100 species of bivalves belonging to 4 orders, 19 families and 49 genera. Among these 47 new species are found to be new distributional records for the Palk Bay area.

The order Neogastropoda or Stenoglossan is generally regarded as the most highly advanced prosobranch gastropods.The large number of species and genera constitutes the success of the Neogastropoda.The classification of the Neogastropods has attracted the attention of many Scientists because the order contain some of the most economically and biologically important gastropods. The over exploitation of these species is now-a-days is increasing rapidly along the South east coast of India.Over the past decades ,the operculum and shells of these gastropods have been fetching a good value but only recently attention has been drawn to the value of their meat. The demand for meat is mainly from exporters and it has now become an additional source of income for their fisher folk. However, it is important to study these snails because of their role in the seafood trade.The knowledge of these resources will be useful for the proper management and conservation of these valuable gastropods. These may have in future excellent opportunities in the aquaculture industry, knowledge of species availability,reproductive biology etc is an essential prerequisites for proper utilization
