家鱼人工繁殖成功与否,与亲鱼的培育有着直接的关系。亲鱼培育得好,繁殖就顺利;反之,繁殖效果差。一、建池要求:亲鱼池位置应选在靠近水源、水量充足、排灌方便的地方,并尽可能靠近产卵池,环境要求清静。面积2—4亩、水深2—2.5尺为宜。二、放养:在亲鱼放养前10天左右用生石灰150—200斤或漂白粉8—10斤彻底清池,清池后检查池水无毒就可放鱼。放养密度,鲢、鳙每亩以200—300斤为宜,草鱼可适当大些。一口塘以养一种鱼为主,并混养少数其他亲鱼或后备亲鱼(即当年不能繁殖的成鱼)。如主养草鱼池塘每亩搭
Artificial reproduction of fish or not, and the cultivation of broodstock has a direct relationship. Breeding broodstock well, breeding on the smooth; the other hand, the breeding effect is poor. First, the pool requirements: Pro-fish pond location should be selected near the water, adequate water, irrigation and drainage convenience, and as close as possible spawning pool, the environment quiet. Area of 2-4 acres, depth of 2-2.5 feet is appropriate. Second, stocking: 10 days before the stocking of fish with lime 150-200 kg or bleach 8-10 catties thoroughly Qingchi, check the pool after the Qingchi non-toxic fish can be put. Stocking density, silver carp, 鳙 per acre 200-300 kg is appropriate, grass carp may be appropriate larger. A pond to raise a fish-based, and polyculture a handful of other broodstock or reserve broodstock (that can not breed adult fish). Such as the main grass carp pond ride
