mannerism

Bighead carp grows in freshwater lakes, rivers, reservoirs and ponds. Mostly distributed in the middle and upper layers of freshwater areas. It is a warm-water fish, with a suitable water temperature of 25-30℃, which can adapt to a more fertile water environment. Young fish and mature individuals generally grow in lakes and attached water bodies along the river.

When they are sexually mature, they lay eggs in the river. After laying eggs, most individuals enter lakes along the river to feed and fatten. In winter, the water level of the lake drops, and they return to the deep water area of the river for the winter. In the spring and warm season of the following year, they go back to breed. The bighead carp lays drifting eggs. Sexual maturity is 4-5 years old, and the youngest male fish is 3 years old. The breeding season is from April to July. The spawning grounds are mostly undulating in the river bed. When it rains in the river basin, the water level rises suddenly and the flow rate increases, breeding activities are carried out.

The spawning season is mostly from early May to mid-June, and mature individuals is also small. Generally, females weighing more than 3 kg can reach maturity. The relative fecundity of 5 kg female fish is about 40,000-50,000 eggs/kg body weight, and the spawning period is similar to that of grass carp. The absolute number of eggs conceived is 200,000-250,000. In natural rivers, lakes and other water bodies, individuals with a weight of 10 kg or more can usually be seen, and the maximum can reach 50 kg.

Under the condition of sufficient feed, 1 year-old fish can weigh 0.8 ~1kg in pond culture. Mature individuals was heavy at first; In some areas, it needs more than 10 kg, but in Guangxi and Guangdong, it is usually less than 10 kg to lay eggs.
