How to breed the knife Loach

Swordfish can be cultured in ponds or in rice fields, with slightly different methods. Pond culture needs to select a suitable pond area and disinfect it before stocking; it can be mixed culture or separate culture. Rice field culture needs to choose deacidified rice fields, do not have too much water, release fish fry per mu should be reasonably matched, and apply as few pesticides as possible to avoid damage to the knife Loach.

How to breed the knife Loach

1, pond culture: pond culture of Loach, generally choose cement pond or Sanhe soil pond, pool depth 70mur100cm, water depth 50Mel 60cm, the bottom of the pond covered with 15muri 20cm thick mud, the area of the pond can be large or small, 2MUE 3 mu is better. The pond should be convenient for drainage and irrigation, and the water inlet and outlet should be protected from escape with barbed wire. Pond cleaning and disinfection should be carried out before stocking, and its method and dosage are the same as those in fish fry ponds.

2. Pond mixed culture: that is, mixed culture with other fish. Such as silver carp, bighead carp, carp, grass carp, carp and other mixed culture. In this way, the selection, cleaning, disinfection and stocking of ponds are the same as those of pond culture.

3. Rice field culture: there is a vast rice area in southern China. Using rice fields to raise Loach can not only save water surface, but also obtain food, and has remarkable economic benefits. It is a good planting and breeding model for high-efficiency agriculture.

4. Rice field selection: weak acidity, less sediment, good water retention and no overflow during rainfall are the best paddy fields for the cultivation of Loach. High ridges should be built around the rice field. two nets should be set up at the inlet and outlet to prevent the Loach from escaping.

5. Stocking and management: put seedlings after transplanting seedlings of early or middle rice. It is generally stocked with 40-50, 000 horses per mu. Before releasing Loach, it is also necessary to apply organic fertilizer to cultivate phytoplankton in the water.
