ABSTRACT
West Bengal is rich in Inland Fishery Resources. Ponds and tanks dominate with 90.62 percent water resources that are brought under culture. Overall 87.56% of total potential water resource is utilized for culture leaving another12.44% for yet to bring under culture. Fishermen constitute about 3.3 percent of total population of 91.3 million in West Bengal. Fisheries are next to agriculture in terms of providing employment and food supply. Fish is an important source of quality protein and cheaper in cost compared to other sources of animal protein. The government is continuously expanding areas under aquaculture. Therefore, there is a steady demand of fish seed for aquaculture. Fish seed is reported to be a constraint for expanding aquaculture in the state. In this communication, it is attempted to examine each of the trends of water area expansion for aquaculture, fish seed and inland fish production as well as demand and supply of fish based on secondary government statistics. The following trend lines were developed. (i) Prediction models on growth of pond fishery(est)=1823.76X+1000,000; R2 = 0.97 (where Y is estimated pond fishery in ha and X is year. (ii)Demand of fish: Y(est.) =15+0.2118X; R2 = 0.9967 (where Y is demand of fish in lakh ton and X is time in years). (iii) Supply of fish as Y(est.) =14.528+0.032X; R2=0.0606 (iv)Prediction Model for Fish Seed Production: Yest=8000+470.8X; R2=0. 864. v) Established relationship between inland fish production and fish seed production of the form Yest =1.9173+0.0007X; R2=0.6785, (where Y is Inland Fish Production and X is fish seed production). Finally, based on trend, appropriate strategy of water area expansion, fish seed production and supply & demand can be explored for sustainable aquaculture growth.
