Culture techniques of fish in ponds

Pond fish is also called Hu Zi catfish, many people may not know much about it, it is a yellow or black body color, the size is not very large edible fish. The main producing areas of pond fish in China are Guangzhou, Fujian and other places. So how much do you know about the pond fish? Do you know how the pond fish are cultured? Next, let's follow the editor to learn the culture techniques of the fish in the pond.

1. Culture preparation

First of all, we should choose a good place to choose and build a good culture pond. In general, we use ponds for aquaculture. The water resources around the ponds are rich, which is convenient for drainage and water change. we trim the bottom of the ponds and arrange anti-escape nets at the inlets and drains. Some aquatic plants can be planted around the pond, which can play a role in purifying water quality and shading. And it is better to set up 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. Fish fry restocking

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

3. Feed feeding

Pond mackerel is a kind of omnivorous fish based on clothing and meat, and its feed types are also very many. For example, field snails, mussels, maggots, fish and shrimp, animal offal and so on can be used to feed pond fish. Of course, if you need high-protein feed, you can also use red worms, earthworms, yellow pink insects and so on. Pond fish usually need to be fed twice a day, around eight o'clock in the morning and around six o'clock in the afternoon. Finally, we should pay attention to the reasonable allocation of feed proportion and feeding quantity according to the change of weather and the growth state of pond fish.

4. Daily management

In the usual feeding and management, we should reasonably apply organic fertilizer according to the fertile degree of the water body and cultivate sufficient plankton to increase natural feed. The second is to change the water frequently, usually every half a month or so to prevent the deterioration of the water quality. of course, if the temperature is higher, we need to adjust the cycle of water change according to the situation. There is to regularly disinfect the aquaculture pond, usually every half a month to 20 days or so with quicklime. The last is to patrol the pond management, check the growth and activities of pond fish, timely understand the weather changes, and take protective measures.

5. Disease control

There are many diseases in pond fish culture, but these diseases are also relatively common and frequent, and may occur in many aquaculture. For example, rotifer disease, third-generation worm disease, water mildew disease, enteritis, melon disease, coccidiosis and so on. We can use cupric sulfate, potassium permanganate solution, salt water, fish germ clear, mercurous nitrate, formaldehyde solution for prevention and treatment respectively.

Today the editor wants to introduce to you the pond fish culture technology here, I believe that through the above reading, the pond fish culture also have a general understanding. If you want to know more about the pond fish, you can leave a message below.
