山区池塘主养青鱼高产试验

Experiment on the High-yield Cultivation of Black Carp in Mountain Area

采取青鱼与搭配鱼重量80:20池塘成鱼养殖法,投放120～150g/尾青鱼种,经263天的精心饲养,出池成鱼规格达到1545g/尾,900.8kg/667m^2,出池比例达81.2%,净增10.3倍,成活率92.5%,总产成鱼1109.5kg/667m^2,投入产出比1:2.29。

The fingerlings whose body-weight was between 120 and 150 grams was put into the pond with about 20 percent of other species.For about 263 days of cultivaton,the boby weight of the fish reached 1545 grams on average,the unit yield was 900.8 kg/667 m^2,the survival rate was 92.5 percent, the ratio of input and output was 1:2.29.
