In natural rivers and lakes and other bodies of water, the larger weight of bighead carp usually seen will be more than 10 kilograms, and the larger ones can be up to 50 kilograms or so, China's largest bighead carp was caught in Zhangjiajie in a farm, weighing 100 pounds. Under the conditions of artificial culture, from the economic benefits of consideration, the breeding cycle will not be too long, the common bighead carp more than ten pounds is normal, twenty or thirty pounds is relatively rare. It can be said that more than a hundred pounds of bighead carp belong to the size of the super large.

A bighead carp can grow up to how many kilograms

1, in the natural rivers and lakes and other bodies of water, usually see the larger weight of bighead carp will be in the 10 kilograms or more, and the big ones can be up to 50 kilograms or so. In artificial farming conditions, from the economic benefits of consideration, the breeding cycle will not be too long, a year a cycle of most of the specifications in the 2 kilograms or so, we common bighead carp more than ten pounds belong to the normal, twenty or thirty pounds of it is relatively rare.

2, the world's largest silver carp was caught in Spain, weighing 206 pounds, converted into our unit of measure for 93 kilograms, an entry into the Guinness Book of Records. The largest silver carp in China was caught in a farm in Zhangjiajie, weighing 100 pounds, the body length is up to 1.5 meters. With reference to these values, you can roughly have a judgment on the growth limit of the silver carp. As you can see, anything over 100 pounds is super-sized.

Second, bighead carp farming ratio

1, general farming bighead carp will be mixed with other fish, such as grass carp, carp, channel catfish, bream, tilapia and so on. In the reservoir fishery production, in the fish species specifications 13.2 cm, stocked species return rate of about 40%, the starting rate of commercial fish to about 70%, adult fish starting standard 1 kg / tail, different nutrient types of large and medium-sized reservoirs each year, the stocking density of fish species and with the proportion of the following:

(1) eutrophic reservoirs: fish productivity of 30 ~ 40 kg / mu, stocking density 110~140 tails/mu, the matching ratio of silver carp is 35~40%, the matching ratio of bighead carp is 50~55%, and the matching ratio of grass, carp, bream and channel catfish is 5~15%.

(2) Medium-nutrient reservoirs: fish productivity of 20-30 kg/mu, stocking density of 80-110 fish/mu, 30-35% bighead carp, 55-60% bighead carp, 5-15% grass, carp, bream and channel catfish, etc.

(3) Medium-nutrient reservoirs: fish productivity of 20-30 kg/mu, stocking density of 80-110 fish/mu, 30-35% bighead carp, 55-60% bighead carp, 5-15% grass, carp, bream and channel catfish.

(3) nutrient-poor reservoirs: fish productivity of 15-20 kg/mu, stocking density of 50-80 tails/mu, the matching ratio of bighead carp is 25-30%, the matching ratio of bighead carp is 60-65%, and the matching ratio of grass, carps, breams, channel catfish, etc. is 5-15%.

2. The mixing ratio between bighead and silver carp as the main fish needs to be adjusted according to the growth rate of the same-age fish. If the individual growth of bighead carp at the same age is significantly faster than that of bighead carp, then the proportion of bighead carp can be increased appropriately; on the contrary, the proportion of bighead carp stocking should be increased appropriately. Bighead carp as the main fish, should be a small amount of with or without stocking bighead carp.
