Comparitive study on culture economics of Litopenaus vannamei between summer and winter seasons along Tamilnadu coastal areas

Shrimp has arisen as a significant consumable product in the world seafood production. Many Asian countries like India, Indonesia, Taiwan, and Thailand have appeared as worldwide leaders in shrimp production. shrimp aquaculture has played a vital role by providing alternative source of income for shrimp farmers along the coastal districts of Tamilnadu and is considered as a sunrise sector for supporting economic development.  In the present study summer culture maximum stocking density was done at Pattukottai (80m2) and followed by Tuticorin region (70 m2). In winter culture maximum stocking density was done at Pattukottai and Tuticorin district (60 m2).  In summer culture the maximum production cost was recorded in Tuticorin region (272Rs) and followed by Ramnad region (237Rs). The minimum production cost was recorded in Nagapattinam region (201Rs) and followed by Ponneri region (206Rs). In summer culture maximum profit obtained from Ponneri region (61%) and followed by Nagapattinam region (57%). The minimum profit recorded from Tuticorin region (22%). In winter culture maximum was recorded Nagapattinam region (56%) and followed by Ponneri region (55%). but in Pudukottai and Pattukottai region recorded same profit in both culture period.
