What kind of fish is a big head fish?

The four major domestic fish in China refer to herring, grass carp, silver carp and bighead carp raised in captivity. The big-headed fish is also known as bighead carp, so people may wonder, what is the big-headed fish?

What kind of fish is a big-headed fish?

Big-headed fish is one of the four famous domestic fish in China. The head of this fish is large and fat, accounting for 1/3 of the body length, the meat is snow-white and delicate, the side of the body is black and spotted, and the eye position is low. Fish brain is rich in nutrition, which contains a kind of fish oil needed by the human body, and fish oil is rich in polyunsaturated fatty acids, which can maintain, improve and improve brain function.

Second, what are the culture techniques of big-headed fish?

1. Seedling stocking

In the past, the stocking specification of bighead carp in lakes and reservoirs was generally about 13.2 fish. Under modern technical conditions, 0.15 kilograms per fish or even 1.0kg large fish species were required.

two。 Stocking time

It should be done in winter or early spring when the water temperature is 5-10 ℃. At this time, it is conducive to the high-density transportation of fish species, which can reduce the casualties in transportation; the activity ability of fish species and ferocious fish is weakened, and the harm of ferocious fish to free-range fish species is also relatively reduced.

3. Stocking site

Should choose in the upstream of the reservoir shallow water, shelter, sunny fertile reservoir bay. In this way, far from the spillway and spillway in the lower reaches of the reservoir, the escape chance of stocking fish species can be reduced, the adaptation time to the large water surface environment can be shortened, the growth can be accelerated, and the survival rate can be improved.

4. Stocking weather

You should choose a sunny day, not a windy, snowy or frozen day.

5. Quarantine and disinfection

Fish disease quarantine and fish seed disinfection must be carried out before fish fingerling are put into storage. It is strictly forbidden to put fish species with infectious diseases into the warehouse.

6. Careful operation

After the long-distance transportation of fish species to the reservoir, the reservoir water should be slowly added to the fish container, and then the fish species should be slowly put into the reservoir when the temperature difference between the container water and the reservoir water is small. After releasing the fish species, the stocking personnel should also stand on the edge of the reservoir or on the boat, gently stir the reservoir water with oars, and slowly drive the fish species to swim to the big water surface.

Big head fish is also known as freshwater fish, its nutrition is rich, it is the first choice of fish head hot pot, and it is not difficult to raise.
