The technique of cultivating Loach in Cage in Pond

Based on the conclusion drawn from many years of culture, the technology of cage culture of Loach in pond has achieved the greatest success.

1. Misgurnus anguillicaudatus seedlings are purchased from the nearest market and strictly screened before putting into the cage to ensure that the fish species are disease-free, lively, fat-shaped and consistent in specification, and soak in 3% salt solution for 10 minutes and then put into the cage. The best time for the release of Loach seedlings in the cage is from May to June 10-20, with a total of about 1200 jin of Loach per mu, with a specification of 5 grams, with an average of 10 square meters per cage of about 30 jin of Loach.

2, the raw material of the cage is made of polyethylene, the type of wire mesh; the length × width × height is 6 meters × 4 meters × 1.8 meters, and the cage frame is made of bamboo poles, each with 6 bamboo poles and 3 long sides, which are directly fixed in the water; the underwater part of the cage is 1.5 meters, the water is 0.3 meters, and the bottom of the cage is about 0.5 meters from the bottom of the pond. 15 days before the stocking of Misgurnus anguillicaudatus, the cage was placed to attach algae to the cage wall, and water peanut and water hyacinth were transplanted into the cage, accounting for 1 / 3 of the cage area. An average of one cage is placed per mu of water.

3. Misgurnus anguillicaudatus is an omnivorous fish. in the whole culture process, the plant bait is mainly rice bran, vegetable cake, wheat flour, potato dregs, corn meal, and animal baits are yellow powder worm, snail, earthworm, maggot, small miscellaneous fish and so on. The weight gain rate will be significantly improved and the benefit will be better.

4. Net should be added to cultivate Loach in cage. The unique intestinal respiratory function of Loach makes the Loach often move up and down in the cage and swallow the air. in the actual breeding production, it is easy to be pecked by waterbirds. Only by adding a net can this phenomenon be avoided.

5. Inspect the pond every morning and evening to check whether the cage is damaged and whether the Loach activity is normal; in the high temperature season from July to August, the water area covered by water hyacinth accounts for 1 beat 2 of the cage; usually remove too many water hyacinth in the cage, so that the coverage area of the cage is maintained at about 1x3.

6. during the whole experiment, the cage was not brushed, and the intestinal respiratory function of Loach was overly relied on, so it was not easy to die from hypoxia. In fact, the cage should be brushed frequently to speed up the exchange of water inside and outside the box, so that the water quality in the box is better and conducive to the growth of Loach.

7. After 5-8 months of feeding, the body weight of Loach can increase by 4-6 times, the average yield of Loach per cage is 120,150jin, and the yield of pond per mu is 4500-5000 jin. In terms of 13 yuan, the output value is 55000-60000 yuan and the net income is more than 30, 000 yuan.

Therefore, the economic benefit of pond cage culture of Misgurnus anguillicaudatus is very considerable, which is worth adopting by breeding enthusiasts.
