Expanded Information:
Pond loach, generally use cement ponds or triple clay ponds, pond depth of 70 to 100 centimeters, water depth of 50 to 60 centimeters, the bottom of the pond paved with 15 to 20 centimeters of thick fat mud, the pool can be a large area can be small to 2-3 acres is good. The area of the pond can be large or small, 2 to 3 acres is good. The pond should be easy to drain and irrigate, and the inlet and outlet of the water should be protected by wire mesh against escape.

If you have the conditions, you can set up a fish collection pit in the center of the pool and near the drainage outlet, so that it is easy to catch in the future. Before loach fry enter the pool, fertilizer should also be applied to promote the proliferation of plankton in the water. To be fertilized after 2 to 5 days, loach species can be placed in the pond. Stocking 30 to 50 kilograms per mu, there are rich water conditions can increase the stocking amount. According to the pond water quality, often cast some organic and inorganic fertilizer to fertilize the water quality.
Additionally, a certain amount of artificial bait should be fed daily. Feeding bait types are fly maggots, fish meal, pig blood powder, silkworm pupa powder, rice bran, wheat bran, vegetable cake and so on.
