The main feature is fast growth, big mouth catfish has low requirements for water quality, more wild, but there are also a lot of artificial breeding. Among them, the moustache catfish is the best, the nutrition is very good, the price is good. So today, we will mainly introduce the breeding methods of bearded catfish, how to breed, what to pay attention to, management details and so on. Please continue to read.

1. Environmental requirements

Require clean water sources, preferably in places with sufficient living water sources to build ponds, and require ponds to be built with better water retention and not permeable. Some non-spreading aquatic plants should be planted in the pond, which can provide a living environment, but can not be blocked by aquatic plants over a large area of the water surface, blocking oxygen and breathing poorly. The inlet and outlet is covered with gauze to prevent other animals from entering and fish from escaping. The surrounding areas should be strengthened and protected.

2. Stocking preparation

After releasing the water two weeks before stocking, wash the whole pond with quicklime solution, soak for a week, and then wash the pond. Then soak in clean water until two days before stocking, re-fill with water after release, ready for release, soak the fish fry in light salt water or other disinfection solution for 20 minutes before release, sterilize, and then release. Prepare the feed to be put into the water.

3. Put in

Generally, about 20,000 fish fry are put in an acre of pond, of course, it can be even less, but it is not cost-effective. Put in the fry of the same specification, not too big or too small, it is easy to grow unevenly and kill each other. Light input, easy to adapt to the environment. It's best to put it at noon when the temperature is right.

4. Feeding

After putting in, you can feed it in a few hours, and some grain can be made into powder and kneaded with water to avoid being too loose and wasteful. You should also feed some shell meat and snail lion meat, which should be chopped and fed. Other small fish and shrimp can be fed. It is best to feed grain powder, nutritional powder and mixed meat together. The approximate amount of feed can be observed that the fish will not be fed if there is no sound. It is usually fed twice a day, and some shrimp are raised in the water as bait.

5. Maintenance

Can fertilize in the water, cultivate natural bait for fish to eat, usually pay attention to change the water, the water source should always flow, rainy days to prevent fish escape, hot days should pay attention to increase oxygen, maintain oxygen in the water. Common printing disease should be treated in time, isolation and whole pool disinfection should be taken. Disinfect with bleach. Common pests, rotifers, parasitic hazards, the use of copper sulfate, ferrous sulfate mixed use.

Moustache catfish is one of the more valuable catfish, breeding should pay attention to environmental conditions, some preparations are in place. Long-term maintenance should not be taken lightly. Pay attention to nutrition in feeding.
