Culture technique of Loach

Misgurnus anguillicaudatus pond requires sufficient water source, fresh water quality, no pollution and convenient injection and drainage. The pond was cleaned, renovated and disinfected 20 days before stocking Loach seedlings. Can be directly fed to aquatic insects, yellow powder insects, earthworms, wild fish and livestock scraps, etc., in addition, we should also pay attention to frequent inspection of escape prevention facilities, timely repair of loopholes, timely treatment of fish diseases.

1. Stocking preparation

The pond was cleaned, renovated and disinfected 20 days before stocking, and barbed wire was used to prevent escape at the inlet and outlet. Dig a fish sliver with a depth of 30 centimeters and 50 centimeters and cover the bottom of the pond with a layer of decaying clay.

2. Bait selection

Artificial breeding can directly feed aquatic insects, yellow powder insects, earthworms, maggots, clams, snails, fish meal, wild miscellaneous fish meat and livestock and poultry scraps, etc., can also be fed with artificial formula feed. The fish were fed once in the morning and evening, usually 3-4% of the body weight of the fish in the early stage of culture and 4-6% of the body weight of the fish in the middle stage, and the amount of compound feed could be reduced appropriately in the later stage.

3. Water quality control

The water quality is required to be "fat, live, tender and cool". The water color is yellowish green and the transparency is 20cm to 30cm. When the transparency is more than 30 cm, 20 kg of organic fertilizer is applied per mu to increase the natural bait organisms of Loach such as radial rent and cladocera in the pond. If the transparency is less than 20 cm, topdressing should be stopped or reduced. In the hot season, new water is often injected, part of the old water is replaced, and the aerator is turned on regularly.

4. Daily management

Persist in patrolling the pond in the morning, middle and evening every day, keep abreast of the water level, water quality and feeding of Loach at any time, and deal with problems in time. Usually weed the pond side frequently, use chlorine dioxide every 15 days in high temperature season, sprinkle quicklime in the whole pool every 7 days, and apply microbial preparation once a month in the middle and later stages of culture. Often check anti-escape facilities, timely repair of loopholes, timely treatment of fish diseases, and make a good breeding diary.
