How to raise herring in winter
Herring culture mainly pays attention to increasing temperature and preventing cold in winter, because the air temperature is low in winter, the dissolved oxygen in the water decreases relatively, while the water level drops due to the freezing of the water surface, resulting in an increase in the density of herring in the pond, so it is necessary to ensure that there is a certain water level in the pond in winter.

Why should the water of crucian carp be salted?
The addition of crude salt or special salt to the water can play many roles, such as increasing the concentration of ions in the water to make the suspended matter sink to the bottom of the water, purifying the water body, balancing the osmotic pressure, alleviating the adverse reactions caused by the fish in the new environment, and replenishing salt to the wound.

The culture density of carp should be mixed with other fish properly.
It is suggested that the culture density of carp is about 3000 jin per mu, which should be mixed with about 300 jin of herring or silver carp and bighead carp, and the culture density of carp mainly depends on the water quality environment, climatic conditions and culture technology of the farm.

Herring culture density
The suitable culture density of herring is about 800-1000 fish per mu, and the reasonable culture density can not only reduce the incidence of herring, but also facilitate pond management in the later stage, during which silver carp or bighead carp can be mixed, which can improve the water quality and promote

For the conditions of herring culture, scientific feeding is the key after site selection and pond construction, and attention should be paid to the regulation of water quality.
Fish ponds: choose places with good water quality to build fish ponds. Selection of seedlings: it is appropriate to choose strong, symmetrical, lively and active fish fry, which should be sterilized before putting them into operation. Bait: scientific proportion of bait, do not overdose to cause water pollution. Feeding: fixed point, regular and reasonable feeding.

The feed formula for herring culture is mainly highland barley feed, and the feed ratio is different in different stages of culture.
The feed formula for herring culture is mainly composed of barley, corn, bean cake, fish meal, wheat bran, crude protein, silkworm pupa, rapeseed cake and wheat bran, and the feed ratio of herring is also different in different culture stages. The feed of herring

Is it easy to raise mandarin fish in winter? Before overwintering, we should reduce the breeding density and build overwintering ponds.
Mandarin fish is not easy to raise in winter, because the best temperature for Mandarin fish growth is about 20℃, and the low temperature in winter affects the growth of Mandarin fish, so it is necessary to build overwintering ponds, and merge ponds in sunny days when the water temperature is above 10℃. Before overwintering, it is necessary to breed them sparsely and deeply, so as to reduce the breeding density

Can I keep herring in the fish pond? The area of the pond should not be too large and can be mixed with other fish.
Herring can be raised in fish ponds, but fish ponds need to be built near the water source without pollution, the area should not be too large and ensure no leakage, and fish fry need to choose high-quality species with no scars and vitality, so that the survival rate of fish fry is higher.

How much is the yield per mu of herring? To increase output, attention should be paid to the density of input and scientific management
Generally, the average yield per mu of cultured black carp is about 2000 jin, if it is cultured with high density and large specification, the yield per mu can reach about 4000 jin, and the specific yield depends on the size, density and breeding conditions of fry.

The breeding technology of free-range native chicken should strengthen the management and improve the laying rate and growth rate.
Venue: choose woodland or orchard to facilitate natural food intake. Chicken vaccine: choose high-quality egg-laying and meat-type chicken vaccines and be vaccinated on time.

The method of river shrimp culture, the water quality is the most important, timely increase oxygen and actively disinfect.
Select a place with sufficient and clear water source to build a pond with an area of 3 mu and a water depth of about 1.2-1.5 m, with an appropriate amount of aquatic plants around the pond to provide shade habitat for river shrimp, and a good escape prevention facility for the inlet of the pond. Disinfect and fertilize the pond before releasing seedlings

There are three stages of mandarin fish culture cycle, seedling cultivation, fingerling cultivation and adult fish culture.
Mandarin fish culture cycle is mainly divided into fry cultivation stage, fish fingerling cultivation stage and adult fish culture stage. Seedling cultivation stage: artificial labor induction and artificial hatching. Fish breeding stage: after the mandarin fry comes out of the film, the egg membrane and dead eggs and other dirt should be screened out with a screen.
