白鲫(Carassus Cariei Tets)是1976年从国外引进的鲫鱼新品种。经试养,它具有比本地鲫生长快、体型大、起水率高、并以吃浮游植物为主等优点。近年来通过较大面积的池塘养殖与移植到湖泊、水库大水体中试养,效果较好,因此,这些年白鲫苗种需求量很大。为了解决白鲫在自然繁殖条件下,产卵不集中、持续时间长与受精率、孵化率低,形成不了大批量鱼苗生产的问题,为此,1987年我们从白鲫亲鱼培育、药物催产、孵化进行了试验。
Carassus Cariei Tets is a new species of carp introduced from abroad in 1976. After the test, it has faster growth than the local crucian carp, body size, high starting rate, and to eat phytoplankton-based and so on. In recent years, large-scale pond culture and transplanting to lakes, reservoirs and other large bodies of water trial and good effect, therefore, the demand for white carp seed in these years is very large. In order to solve the crucian carp in the natural breeding conditions, lay eggs are not concentrated, long duration and fertilization rate, hatching rate is low, can not form a large number of fish fry production problems, therefore, in 1987 we white carp parent fish cultivation, drug oxytocin, Incubation was tested.
