摘要
1998年 ,在沅江市白沙乡八形汊渔场的上湖 (16 0hm2 )进行了套养鳜鱼与下湖 (140hm2 )未套养鳜鱼的对比试验。结果 ,上湖平均鲜鱼产量 2 810 6kg/hm2 ,比下湖的 2 915 7kg/hm2 低 10 5 1kg/hm2 ,但上湖的产值、利润、投入产出比分别为 17973 75元 /hm2 、886 3 13元 /hm2 、1∶1 97,依次分别比下湖的 11496 43元 /hm2 、4813 5 7元 /hm2 、1∶1 72高 36 0 %、45 7%、12 7%。
In 1998,a test on poly culture Sinipera chuatsi was carried out in Baisha country,Yuanjiang,city.The Siniperca chuatsi was being bred in the upper lake and not being bred in the lower lake.The results show that the output of the upper lake is 2810.6 kg/hm 2 which is 106.1 kg/hm 2 lower than the output of the down lake which is 2915.7 kg/hm 2,But the output value,profit ,the ratio between the input and output is 17913.75yuan/hm 2,8 863,13yuan/hm 2,1∶1 97,respectively.They are 36.0%,45.7%,12 7%higher than that of the down lake which is 14496.43yuan/hm 2,4813.57yuan/hm 2,1∶1 72。
