Techniques of raising carp

Carp, also known as carp crutch, is a very common freshwater fish in our life, and it is also a kind of omnivorous fish. Carp is rich in protein, and the utilization and absorption rate of protein is very high, so it is a very high quality protein. But today we are mainly here to learn the breeding techniques of carp, so please take a look at the wonderful content below.

1. Parent fish selection

Before carp breeding, we should first cultivate parent fish, so carp parents should generally choose species with good physique, strong, energetic, active, disease-free, no mechanical injury, no parasites, high reproduction rate, and the ratio of body length to height is three to one. Carp parent fish female fish generally about three jin, male fish is more than two jin is appropriate. Females should choose a wide body, a high back, a small head and a wide and soft abdomen. Males should choose those with a larger head, a small and hard abdomen, and a slightly concave anus.

2. Feeding and management

In order to enhance the resistance and reproductive ability of carp parents, we must raise them scientifically. The feed of parent fish is generally bean cake, silkworm pupa, fish meal and other high protein content feed, which is very beneficial to the growth of parent fish. Secondly, in the process of culture, we should pay attention to the regulation of water quality, change water frequently, and it is best to keep the water flowing slightly in the culture pond, which can promote the development of sex hormones and enhance the fecundity of carp parents.

3. Accelerate the birth and incubation

When the water temperature in the aquaculture pond rises to about 16 degrees, and the water temperature is relatively stable and does not cool down, it is time to induce labor. Generally speaking, we induce labor during the period from Qingming Festival to Grain Rain. The way of inducing spawning is divided into natural spawning and artificial spawning, and the management mode is also divided into natural hatching and debonding hatching. During the induction of labor, the main feed formula is bean cake, flour, milk powder, broad bean powder, corn powder and spices in a ratio of five to one mixed with water.

4. Seedling cultivation

After the breeding of parent fish, we should put the hatched seedlings into the breeding pond for cultivation. The breeding pond should be disinfected with quicklime before releasing seedlings, and the impurities in the breeding pond should be cleaned up with a dense net, and then the carp seedlings should be put into the breeding pond. During the breeding period, we mainly feed with soybeans and cooked egg yolk, and the earlier the fry begins to eat, the better it grows. During the fry cultivation period, it is necessary to strengthen inspection and observation, record the fry activity, growth, feeding, water quality changes, enemy damage, diseases, and timely management and prevention. In addition, four principles must be followed when feeding, which has an important impact on the growth of fish fry. Finally, it is necessary to do a good job in flood control and escape prevention.

These are the breeding techniques of carp that the editor is going to introduce to you today. In the above, the editor simply skipped the cultivation and reproduction of fish fry and did not give a detailed answer. If you are interested and want to know, you can leave a message below.
