Technique for high yield of fish culture in the small-sized reservoir

Studies were carried out on fish culture model, fingerlings releasing, net cages setting and manure spreading. In 41 experimental reservoirs with the total area of 351 ha the total output of the adult fish was 1283.6t, the per mu yield of 220.7kg on average, raised 3.27 times than the three years of yield before exploitation. The net profit was 586.95yuan per mu and the ratio of input and output was 1:1.92.
