在批林整风运动推动下,我们积极开展科学实验,成鱼产量连年提高,池塘成鱼亩产从三、四百斤上升为六、七百斤,高产试验塘达到千斤以上。总结几年来科学养鱼的经验,我们有以下几点体会:一、多品种分层放养,充分利用水体。初养成鱼时,由于缺乏草鱼饲料,我们 Under the auspices of the campaign to rectify forest winds, we actively carried out scientific experiments. The yield of adult fish increased year after year. The yield per mu of ponds rose from three or four jin to six or seven jin and the yield reached more than one kilogram. Sum up the past few years the scientific experience of fish farming, we have the following experience: First, multi-species stratified stocking, make full use of water. Initially raised into fish, due to a lack of grass carp feed, we
