金沙江鲁地拉电站建成,为渔业增殖和养殖提供129.45 hm~2水面。以短须裂腹鱼为材料,通过网箱设置、苗种投放和投饲管理,进行鱼种培育和成鱼养殖试验,总结裂腹鱼养殖模式和养殖技术,为电站库区推广养殖提供技术指导。试验结果:投放短须裂腹鱼1龄鱼种34 560尾15.62 kg,体重0.45 g,平均体长为2.77 cm,经12个月培育鱼种30 615尾685.7 kg,尾重达22.40 g,增加21.95 g,增重48.78倍,平均体长达10.06 cm,增加7.29 cm,增长2.63倍,成活率88.59%,饲料系数2.58;投放2龄鱼种16 732尾261.81 kg,体重15.65 g,平均体长为9.89 cm,经12~13个月饲养总产成鱼14 022尾2 046.10 kg,尾重达145.92 g,增加130.27 g,增重8.32倍,平均体长达17.46 cm,增长7.57cm,增长0.77倍,成活率83.80%,饲料系数2.99。结果表明,短须裂腹鱼具有生长快、病害少的特点,网箱培育鱼种和成鱼养殖效果较好。
The Jinsha River Ludila Power Station is completed, providing 129.45 hm ~ 2 surface water for fishery breeding and breeding. In order to promote the culture of power station reservoir area, the method of culturing fish breed and breeding fish was carried out through the setting of cages, the delivery of seedlings and feeding management. guide. The results showed that the first instar species of Crataegus schrenneria were 34 560-tailed 15.62 kg and weight 0.45 g with an average body length of 2.77 cm. After 12 months, 30 615 and 685.7 kg of fish were cultivated with a tail weight of 22.40 g, 21.95 g, 48.78 times weight gain, average body length of 10.06 cm, an increase of 7.29 cm, an increase of 2.63 times, the survival rate of 88.59%, the feed coefficient of 2.58; Which was 9.89 cm. After 12-13 months, the total fish production was 14 022 and 2.0466.10 kg, with a tail weight of 145.92 g and an increase of 130.27 g and a weight gain of 8.32 times, with an average body length of 17.46 cm and an increase of 7.57 cm, an increase of 0.77 Times, the survival rate of 83.80%, feed coefficient of 2.99. The results showed that the short-bell cracked fish had the characteristics of fast growth and less disease. Cage breeding fish and adult fish farming were better.
