Trend analysis of inland fish production of Tamil nadu with special references to resources and seed production

Inland fishery resources are significantly contributed in fisheries sectors. In this regard, trend of inland fish production of Tamil Nadu was analyzed based on the available resources and utilization and seed production for the last decade. Calculated Average Annual Growth rate of fish seed production and inland fish production were 10.21% and 1.85%, respectively. The linear regression line for inland fish production was indicated that increasing trend for every year (R² = 0.673), while fish seed production was negative trend (R² = 0.094). Also, the positive relationship was existed between fish seed production and inland fish production of Tamil Nadu, which was proved by R² = 0.503. In this regard, Tamil Nadu also has vast inland fishery resources (3.83 lakhs ha.) in the form of ponds, tanks, river, reservoirs and brackish water with potential of the state is 4.5 lakhs tons but the present fish production was 2.15 lakhs tons only (2016-17) due to 46.67% of potential resources were underutilized condition. Moreover, it has significant open water and inland farming resources were 87% and 13%, respectively with the inland fish production of 70.7% and 29.3% respectively, which proved that open water resources were highly contributed in inland fish production, even if considerable areas were underutilized condition while comparing to inland farming area. The study recommends that proper utilization of natural resources may increase the inland fish production of the state. | Trend analysis of inland fish production of Tamil nadu with special references to resources and seed production
