In order to cultivate pond fish, we should first choose the right place and build a good breeding pond. Under normal circumstances, we all use ponds for aquaculture. The water resources around the aquaculture ponds are rich, which is convenient for drainage and water exchange. The bottom of the ponds is leveled, and anti-escape nets are arranged at the water inlet and the water outlet. Some aquatic plants can be planted around the pond, which can purify the water quality and hide in the shade. It is also best to arrange a fence around the pond to prevent the enemy from entering. Finally, the pond is disinfected with quicklime before stocking to reduce the probability of disease.

2, fry stocking

We should choose the seedlings with good physique, strong health, no disease infection, no external and internal harm, and uniform size. Before stocking, we also need to disinfect the fry, which is usually washed in dilute salt water for about 10 minutes. Finally, according to the density of stocking 20,000 to 30,000 fish per mu, the fry can be put into the culture pond.

3. Feed feeding

Pond-fish is an omnivorous fish species that mainly eats meat and clothes, and its feed types are also very many. For example, snails, mussels, maggots, fish and shrimp, and animal offal can all be used to feed pond fish. Of course, if you need high-protein feed, you can also use feeds such as red worms, earthworms and Tenebrio molitor. Generally speaking, pond fish need to be fed twice a day, at around 8: 00 in the morning and around 6: 00 in the afternoon. Finally, we should pay attention to the reasonable allocation of feed ratio and feeding amount according to the weather change and the growth state of pond fish.

4. Daily management

In the usual feeding management, we should apply organic fertilizer reasonably according to the fertility of water body, and cultivate enough plankton to increase natural feed. Secondly, it is necessary to change the water frequently, usually every half month or so, to prevent the water quality from deteriorating. Of course, if the temperature is high, we need to adjust the water change cycle according to the situation. There is also the need to disinfect the aquaculture pond regularly, usually once every half a month to twenty days or so with quicklime. Finally, it is necessary to patrol the pond, check the growth and activities of pond fish, know the weather changes in time, and take protective measures.

5, disease control

There are many diseases in pond fish culture, but these fish diseases are also common and frequent, which may occur in many aquaculture. For example, wheel disease, third generation disease, water mold, enteritis, small melon disease, cercariasis and so on. We can use copper sulfate, potassium permanganate solution, salt solution, fish germ serum, mercurous nitrate and formaldehyde solution for prevention and control respectively.
