长江刀鲚(Coilia nasus)“生态活水”育种研究

Study on the Cultivation of Coilia nasus Seedlings in “Ecological Living Water”

为提高刀鲚生态养殖水平,开展了刀鲚“生态活水”育种试验。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亩产量分别为19.06 kg和20.2 kg,分别比对照池高出23.0%和30.5%。试验池亩平纯效益分别达8130元和8294元,比对照池亩平纯效益3893元分别提高1.08倍和1.13倍。

In order to improve the ecological cultivation level of Coilia nasus, the experiment of cultivating Coilia nasus seedlings with "ecological living water"was carried out. The experiment shows that "ecological living water"can improve the ecological environment of the pond, accelerate the growth of Coilia nasus seedlings, improve the survival rate, realize energy conservation and con-sumption reduction, reduce costs, improve quality, increase production and income. The average yield per 667 square meters of Coilia nasus was 19.06 kg and 20.2 kg respectively, 23.0% and 30.5% higher than that of the control pond. The net benefits of the test tank per 667 square meters are 8130 yuan and 8294 yuan respectively, which are 1.08 times and 1.13 times higher than those of the control tank per 667 square meters.
