我省有大小水库11,278座,养鱼面积140万亩,其中小型水库的面积占72.6%。据近年统计,小(一)型水库成鱼平均亩产18斤,小(二)型亩产26斤,存在着“单产不高,总产不稳”的局面。为了提高小型水库成鱼产量,我们从1980年起在我省泸县玄滩公社幸福水库(面积106亩)进行了水库养草鱼提高成鱼产量的试验。通过两年工作,使这个水库成鱼单产由试验前六年年平均的162斤/亩上升到266
There are 11,278 large and small reservoirs and 1.4 million mu of fish in the province, of which 72.6% are small reservoirs. According to statistics in recent years, the average fish yield of small (a) type of reservoirs is 18 kg and that of small (b) type is 26 kg per mu. There is a situation where the yield per unit is not high and the total output is not stable. In order to improve the fish production of small reservoirs, we started to experimentally raise the fish production of fish in the reservoir in Happiness Reservoir (106 mu) in Xuantan Commune, Lu County, our province since 1980. After two years of work, the yield of fish in the reservoir rose from 162 kg / mu on average in the first six years of the experiment to 266
