Common misunderstandings of cultivating Loach in cement Pond

Do you know the common misunderstandings and solutions of cultivating Loach in cement pond? In recent years, the price of Loach has been rising, the number of wild Loach has decreased year by year, and many people have failed in breeding. Now several common misunderstandings and solutions are summarized.

Buy seedlings indiscriminately

Many farmers go to other places to buy so-called imported high-quality seedlings at high prices. Due to long-term temporary cultivation and long-distance transportation, the mortality rate can reach 70-90%, resulting in breeding failure.

Solution: at present, there is no special breed for breeding. The local Misgurnus anguillicaudatus and Paramisgurnus anguillicaudatus are farmed. The former has strong disease resistance and the latter grows fast. You can choose Loach seedlings according to your own situation.

Improper stocking

The Misgurnus anguillicaudatus with a size of more than 10 cm has eggs in the body, the transportation operation is slightly improper, and the mortality rate is as high as 80-100%, so it cannot be stocked.

Solution: from February to March, the temperature difference between day and night in the pool water varies greatly, so it is appropriate to put large seedlings of 8-10 cm, and seedlings of 5-7 cm from April to May.

The construction of cement pool does not accord with the ecological habits of Loach.

Misgurnus anguillicaudatus often has rotten mouth disease, the condition is light, thin, heavy death, some mortality rate is more than 40%, the curative effect is still not ideal. In fact, the disease is caused by the construction of the cement pool does not conform to the ecological habits of Loach, Loach is very sensitive to surface vibration, when the surface vibration of Loach will be frightened out of 5-6 meters, Loach vision is poor, if the pool is too small, mouth easy to hit the pool wall injury caused by the disease.

Solution: the area of the cement pool should not be less than 200-300 square meters and the corner of the pool should be round. Soda was removed with blisters for 20-30 days before seedling release in the new pond, and then fully mature chicken manure was wrapped in sack slices, 5 kg each, 10-20 packets per mu. When the pond wall turned green, the sack bag was taken out and put into the Loach seedlings, which can effectively prevent Loach rotten mouth disease.

Abuse of manure

The small water body and excessive application of manure fertilizer in Loach Pond can easily corrupt the water quality and induce diseases. Be sure to pay attention to the time of fertilization.

Solution: when the water transparency is more than 35 cm, use sack slices to pack fully rotten chicken manure, 5 kg each, 10-20 packets per mu; when the water transparency is 20-25 cm, take out the sack bag in time.

Ignore the role of aquatic plants

Fish farming first raises water, and grass carp is only fat. According to statistics, in the case of water plants, the survival rate of Loach is 1.07 times higher than that of soil and 1.46 times higher than that without shelter. Therefore, it is not feasible to raise Loach with the method of raising conventional fish in Baitang.

Solution: plant water hyacinth, water peanuts and other water plants in the Loach pond. The roots of these aquatic plants are well developed, which not only provides a safe habitat for Loach, but also plays a role in preventing heat and cooling and purifying water quality.
