Shrimp Farming in Tamilnadu
The technical improvements made in shrimp farming in many parts of the world paved the way to increase shrimp farming through aquaculture by adopting semi intensive systems of shrimp farming in the areas where environmental conditions are well suited. Tamil Nadu is endowed with rich natural resources such as coastal zones in the form of brackish water/estuaries for shrimp culture. At present shrimp aquaculture has been developed in 13 maritime districts of Tamil Nadu in about 5745.01 hectare. The giant tiger shrimp (P. Monodon) and white leg shrimp (P. Vannamei) are the most common species cultured in shrimp ponds. The farmers are encouraged to adopt semi intensive farming methods for sustainable aquaculture.

Shrimp Farm Regulation
In the light of the promulgation of Coastal Aquaculture Authority (CAA) Act 2005 and its notification of Rules & Guidelines by the Central Government, every shrimp farm functioning or proposed to be constructed should obtain registration from CAA. The farms which are established after the above said act should be situated 200 meters away from High Tide Line (HTL).
The CAA has formed District Level Committee (DLC) for Processing of applications with the District Collector as Chairperson and members from Departments of Revenue, Agriculture, Environment, Fisheries and Panchayat Representative for processing the application for Registration under CAA. For farms up to 2.0 ha water spread area (WSA), the District Level Committee upon satisfaction shall recommend the application directly to CAA and for farms above 2.0ha WSA the DLC should recommend to the State Level Committee (SLC).
