Can catfish and loach be raised together?

Catfish and Misgurnus anguillicaudatus can not be raised together, not because of the problem of water area, but because Misgurnus anguillicaudatus is small and large, while catfish belongs to carnivorous fish, Loach is herbivorous fish, if catfish and Loach are raised together, Loach can be easily eaten by catfish.

Catfish is large, carnivorous, Loach is small, herbivorous fish, so catfish and Loach should not be raised together, catfish will lose the Loach pond.

Culture techniques of catfish

1. Release seedlings

The resistance of fish fry is weak and varies in size. If you directly put the fry into the pond, the fry will have a larger range of activities and more physical consumption, so it is difficult to eat the bait put into it, which will cause the death of fry and pollute the water quality. Therefore, farmers should cultivate fish fry twice, first concentrate on intensive culture in small ponds, and then put them into big ponds.

This is not only convenient for management, but also can reduce the loss of fish fry, so that fish fry can better adapt to the environment, fish fry in the small pond can easily eat enough food, can grow quickly.

When the fry in the small pond is cultivated to about 15 cm, the large fry can be screened inside and put into the big pond to raise, and the small fry is still cultivated in the small pond. When the fry growth is balanced and the specifications are the same, then put into the big pond to raise, so as to avoid big fish eating small fish, effectively improve the survival rate of fry and the increase of fish production.

2. Rational feeding

Catfish is carnivorous fish, more gluttonous, so to master the correct feeding method, feeding according to the number of fish, do not bait blindly. Feeding should be dispersed, bait should be evenly distributed, and a small number of meals should be achieved to prevent uneven hunger and satiety, resulting in polarization.

In the initial stage of fish fry cultivation, animal feed should be given priority to. When the fish is getting bigger and bigger, it should be gradually converted to plant feed, which should be combined with animal and plant feed. The daily feed intake is controlled according to 50.8% of the fish's body weight. According to the growth of the fish, it is more reasonable to adjust the feeding amount once a week or half a month, so that the fish can grow better.

3. to carry out rotation and separate cultivation.

Catfish is a ferocious fish, in feeding, big fish grabs food while small fish can not eat food, so the difference in fish size will become more and more obvious, so catfish in a period of time, to carry out rotation and separate culture, the big fish and small fish separate, which can improve the production of fish, but also can make the speed of fish growth to balance.

4. Advocate catfish overwintering

When the fish is raised to the market specification, when the fish is sold, a small number of adult fish can be moved to the deep pool for winter, which can not only solve the low sales price of catfish in the peak season, but also prolong the supply time of catfish, and in the case of few catfish, fish prices can be doubled, bringing good economic profits to farmers.
