利用“生态活水”培育刀鱼种试验

Experiment on the cultivation of Coilia nasus fry by using “Ecological Living Water”

为提升刀鲚生态养殖水平,开展了"生态活水"培育刀鲚鱼种试验。试验表明,"生态活水"能全面改善池塘生态环境,加快刀鲚苗种生长,提高成活率,实现节能降耗节本和提质增产增收。试验池刀鲚鱼种平均单产分别为19.06 kg/667 和20.2 kg/667 m^2,分别比对照池高出23.0%和30.5%。试验池单位面积平均纯效益分别达8 130元/667 m^2和8 294元/667 m^2,比对照池的3 893元/667 m^2分别提高1.08倍和1.13倍。

In order to improve the ecological breeding level of Coilia nasus, the experiment of"ecological living water"was carried out. The results showed that"ecological living water"could improve the ecological en vironment of pond, accelerate the growth of C. nasus, improve the survival rate, realize energy saving, cost saving,quality improving, yield increasing and income increasing. The average yield per 667 m^2 of C. Coilia in the experimental pool was 19.06 kg and 20.2 kg respectively, which was 23.0% and 30.5% higher than that one in the control pool. The average and pure benefit per 667 m^2 of the experimental pool was 8 130 yuan and 8 294 yuan,respectively, which was 1.08 times and 1.13 times higher than that of the control pool(3 893 yuan).
