Water harvesting and fisheries in poly-lined pond in temperate region under front-line demonstration

Abstract

The soil of district Doda of Indian UT of JK final weight was 570gm/year with about 81% survival rate. The study of the cost/benefits ratio parameters indicated that there was an input cost (seed and feed cost) of about Rs. 1600/- (average) for one year operation of the above said pond, while the cost of the produced fish was about Rs. 13785/ per pond per year. Therefore, poly-lining of earthen pond or concreted ponds with cracks, are recommended for temperate regions where heavy water loss due to seepage is common. Poly-lining may not only ensure water availability round the year but can also increase farmers income several fold by providing table size fish to the market.
