人工繁殖鲤鱼与“四大家鱼”相比,其难处首先是由于鲤鱼属多次性产卵鱼类,卵子发育不同步,易导致零星产卵,其次是鲤鱼对激素反应不如家鱼敏感,由于亲鱼成熟度不一,效发时间差异性较大,常常发生雌鱼排卵与雄鱼排精不协调,致使“白卵”多,受精率低。给生产造成损失,再者,鲤鱼卵易感染水霉,孵化率低,鉴于以上各种情况,我们认为,应做好以下工作。首先要加强亲鱼培育,实行人控产卵。鲤亲鱼培育池,以面积1～3亩,水深1.5米左右较好,一般宜专池培育。秋季是鲤鱼性腺发育的重要阶段,要大量投以富含蛋白质的饲料,让其吃饱吃好。冬 Artificial breeding of common carp and the “four major domestic fish,” compared to the difficulties are due to multiple carp spawning fish, oocyte development is not synchronized, easily lead to sporadic spawning, followed by carp hormone response less than the sensitivity of the fish due to The maturity of broodstock is different, and the time of onset is quite different. It is common that female ovulation does not coordinate with male infertility, resulting in more “white eggs” and lower fertilization rate. Resulting in loss of production, in addition, common carp eggs susceptible to water mold, hatching rate is low, in view of the above circumstances, we think, should do the following work. First of all, we must step up broodstock breeding and practice human-controlled spawning. Carp broodstock breeding ponds, with an area of ​​1 to 3 acres, a depth of about 1.5 meters better, the general should train special pool. Autumn is an important stage of carp gonadal development, to cast a large number of protein-rich feed, let them eat well. winter
