Grass carp is a common freshwater fish, is one of the "four major domestic fish.". There are wild species of grass carp that live in rivers; Grass carp also has artificial breeding varieties, generally speaking, are large-scale farming. Grass carp can only reproduce after reaching the age of sexual maturity, and female grass carp can lay eggs.
In terms of age, grass carp will be sexually mature at the age of 3 or 4. From the weight point of view, grass carp enters the stage of sexual maturity when its weight reaches about 5 kg. But sometimes some grass carp are relatively early, sometimes less than 3 years old have the ability to reproduce. Wild grass carp usually spawn in turbulent rivers, not in still water. For example, in the confluence of dry tributaries, deep grooves of river bends and so on, grass carp often spawn. If you want to breed grass carp artificially, it can also be carried out after their 3-4 age sexual maturity, and the success rate of reproduction is relatively high.
Grass carp can reproduce after sexual maturity, and their reproductive capacity is relatively strong. The reproductive period of grass carp is concentrated in April-July every year. Especially in May, it is the peak period of reproduction and spawning of grass carp. During this stage, the phenomenon of grass carp spawning can often be seen in rivers. Grass carp can reproduce more than once a year, sometimes female grass carp lay eggs twice a year, sometimes three times a year. Specifically, it is uncertain, depending on whether the surrounding environment is suitable, especially the water temperature. If grass carp have enough rest after one reproduction, they can carry out the next reproduction and spawning process.
