Grass carp is a common fish, they can reproduce. However, in order to reproduce grass carp and reproduce successfully, certain conditions need to be met. First of all, an important aspect is the age condition, too small, gonad has not yet mature grass carp can not reproduce, only after sexual maturity of grass carp can reproduce, generally speaking, at the age of 3 or 4. In addition, the water temperature conditions, only when the water temperature is stable at about 18 degrees, grass carp can reproduce. In the case of very low temperature or very large temperature difference between day and night, grass carp generally do not breed, even if the success rate of reproduction is relatively low.
Wild grass carp can generally reproduce themselves, but they need to meet certain conditions. In addition to the age conditions and water temperature conditions mentioned above, another condition is very important, that is, water flow conditions. Wild grass carp will spawn in flowing water after sexual maturity and breeding season, and only under such conditions can they promote spawning. After spawning, the eggs are fertilized and float away, hatching in due course. If the water environment in which grass carp live is very static, then they generally can not successfully reproduce.
Artificially raised grass carp are generally unable to reproduce themselves, because the above-mentioned flowing water conditions cannot be met, and the water flow is generally static when they live in fish ponds. However, because the demand for grass carp fry is relatively large, farmers generally carry out the process of artificial incubation of grass carp. The specific reproductive process is similar to that of wild grass carp. The first is to promote female ovulation, and then to promote male ovulation of sperm, after the eggs and sperm are combined, they are placed in a similar loop, which can simulate the flowing water environment and hatch the fertilized eggs.
