慈利县罗非鱼繁殖场从1987年以来,采用地热水提高亲鱼池水温,进行亲鱼强化培育和地热水刺激等技术措施,人工繁殖鱼苗的时间提早20～30天。摆脱了自然气候条件的制约,延长了鱼苗的生长期,提高了成活率,取得了较好的社会经济效益。 1 条件与措施 1.1 慈利县罗非鱼场有亲鱼池46口,水面31亩;园形产卵池2口,30m~2;孵化槽8口,13m~2。有亲本:草鱼100尾,9kg/尾;鲢鱼200尾,4kg/尾;鳙鱼10尾,10kg/尾;鲤鱼100尾,1.25kg/尾;胡子鲶80尾,2.5kg/尾;尼罗罗非鱼1580尾,0.4kg/尾;温泉水为优质矿泉水,流量
Tilapia breeding ground in Cili County Since 1987, geothermal water has been used to raise the water temperature of the broodstock ponds and to carry out intensive cultivation of broodstock and geothermal water stimulation. Artificial breeding of fry lasted 20-30 days earlier. Get rid of the constraints of natural climatic conditions, extending the growth of fry, increased survival rate, and achieved good social and economic benefits. 1 Conditions and Measures 1.1 Tilapia Cili County has 46 broodstock ponds, 31 acres of surface water; garden oviposit 2, 30m ~ 2; hatch 8, 13m ~ 2. There are parents: grass carp 100, 9kg / tail; silver carp 200, 4kg / tail; catfish 10, 10kg / tail; carp 100, 1.25kg / tail; bearded catfish 80, 2.5kg / tail; Tilapia 1580, 0.4kg / tail; hot spring water for high-quality mineral water, flow
