What matters should be paid attention to by farmers in fish culture in spring?

Spring is the season for setting out fish species. In order to achieve high fish yield and good economic benefits, farmers need to pay attention to the following five things:

fish

First, pay attention to early release of seedlings

If the ponds for adult fish culture are not released in autumn, after the beginning of spring, when the water temperature reaches 7-8 ℃, the fish fry should be put in as early as possible, so that the fish can adapt to the environment and grow early, and the ponds should be strictly disinfected before restocking.

Pay attention to the regulation of water quality

After a long overwintering period, the water quality of the pond is easy to aging or slightly acidic. Attention should be paid to changing water as early as possible, so as to make the fish grow in an environment with fresh water quality, which is conducive to growth, and can reduce the occurrence of some diseases. Generally, the water level can be kept at about 0.8m after water change, which is conducive to the rise of water temperature, maintain a higher water temperature, and promote the growth of fish. To prevent the water quality from deteriorating.

Pay attention to eating as early as possible

In order to restore the fish's physique and grow early, we should pay attention to baiting the fish early so that it can start eating early.

Fourth, pay attention to timely fertilization

After changing water at the beginning of spring, fertilizing and fertilizing water should be applied in time according to the situation of water quality, which can not only make the fat and water fish in the pond have sufficient bait supply, make them eat and grow early, but also help to raise the water temperature and accelerate the growth of fish. the specific amount of fertilizer application can be flexibly controlled according to the water quality.

Pay attention to the prevention and treatment of diseases

After the beginning of spring, the water temperature is low, the physique of fish is poor, improper management of fish is easy to get sick, so we should pay attention to early prevention of disease.
