我场于1985年以来用本场面积9.6亩的鱼塘进行分格培育鲢鳙亲鱼,即把原来的大塘用白夹竹分而围成4块2～2.6亩不等的长方形小水体,使亲鱼分开培养,而水体相连。通过五年实践证明,亲鱼分格培育后,成熟早、催产率高、生产稳定。一、避免了因拉网而影响催产效果。以往,我场经常遇到在同一池里,第一天拉网催产效果很好,第二天的鱼次之,再后的就催而不产了。这主要是拉网惊吓引起的
My field since 1985 with an area of ?? 9.6 acres of fish ponds were sub-grid to cultivate silver carp and bighead carp, that is, the original big pond with white bamboo points and surrounded into 4 2 ~ 2.6 acres of rectangular water body, Broodstock to cultivate separately, and the water body connected.

First, to avoid pulling the net and affect the effect of oxytocin. In the past, my field often encountered in the same pool, the first day pull net oxytocin good effect, the second day of the fish second, then the reminder but not produced. This is mainly caused by dragging scared
