Abstract: India is a vast country with having varied and enriched natural resources. The natural resources like freshwater, marine water and the brackish water are important in production and development of resources. India has huge potential brackish water resources and these brackish water resources include estuaries, coastal lagoons, mangrove swamps and coral reefs supports a varied biological resources, such as fishes, prawns/shrimps, crabs, mussels, (clams, cockles, and oysters), lobsters, and other with their seed resources as well as sea weeds. India has 1.30 million ha. brackish water area suitable for aquaculture. (Ghosh, 2010). Out of which, at present about 1.41 lac. ha. area is presently under aquaculture (traditional, improved extensive and semi-intensive systems). And the estuaries covered along North Kanara district are Kalinadi, Aghnashini and Sharavati. The mid 1980s to early 1990s was a period of rapid growth in the production of cultured shrimp, particularly in South East Asia and Central America. Overall global fish production was estimated to be 140 million tons during 2009. Aquaculture production has contributed to 36 million tons in 2002 and reached to 50.3 million tons in 2OO7.This indicated that 6.5% growth was recorded in aquaculture alone. Shrimp production from both capture and culture was accounted to be 6.6 MT in 2009. China, leading first in shrimp production with 2.7 MT, followed by India and Thailand. However, the shrimp aquaculture industry has received unprecedented criticism for unsustainable practices. This has included the discharge of pond waters of high nutrients load and contributed to high phytoplankton to cause eutrophication of coastal waterways, destruction of mangrove and wetland habitats and depletion of world fish stocks to make shrimp feed. 4'he continuation of unsustainable practices has the potential to significantly hamper production of shrimp. The future of the shrimp industry relies on the development of more sustainable and best management practices.
