Silver carp is a common fish, belonging to freshwater fish. Silver carp can live in rivers, lakes and other freshwater waters, and can also live in artificial breeding conditions. Silver carp can reproduce themselves. Wild silver carp usually reproduce themselves, but they need to meet certain conditions. First of all, age conditions, silver carp can only reproduce after sexual maturity; Then is the water temperature conditions, in the surrounding water temperature is very low, silver carp can not reproduce, at least when the water temperature is stable at about 20 degrees, silver carp can reproduce. Specifically, in April and May of each year, the reproductive behavior of silver carp is very common. In fact, in the Yangtze River, Pearl River, Heilongjiang and other river basins, there are natural egg farms for silver carp.
Artificially reared silver carp can also reproduce themselves, but breeders generally do not let them reproduce themselves, but carry out the artificial reproduction process. This is because they can not guarantee the hatching rate if they reproduce themselves, and the current demand for silver carp fry is still relatively large, the success rate of artificial reproduction is relatively high.
As mentioned above, silver carp can reproduce, but the first condition to be met is the age condition, that is, silver carp can reproduce only when they are sexually mature. Silver carp sexual maturity is relatively early, about 3 years old on the sexual maturity. There are also some silver carp relatively early, in more than 2 years old to reach the age of sexual maturity. From the weight point of view, when the weight of silver carp reaches about 3 kilograms, they generally have reproductive capacity. When the specific reproductive process, it is best to select more mature, heavier silver carp, the success rate of reproduction is relatively high, do not choose just sexually mature age of small silver carp.
