1, build a pool: should choose the direction of sunrise, reliable water, clean environment, easy to manage, good soil quality, no leakage of the place to build a pool. If there are conditions, you can also use l:2 cement mortar masonry. Area can be adapted to local conditions. Generally 100-200 square meters, 1 meter deep, maintain the water depth of 40-50 cm. The bottom of the pool paved 20-30 cm of fat mud, so that loach drilling and diving habitat. For the convenience of drainage and irrigation, the pool needs to be set up inlet and outlet, and make a good stop loach equipment (such as wire mesh, etc.).

2, clean pool disinfection: general mu with 50 kg of quicklime disinfection, injected into the new water, and appropriate application of some manure to fertilize the water quality. Be sure to wait for the medicinal properties of about 7 days after the disappearance, before stocking.

3, stocking loach species: artificially propagated or wild can be, but requires no disease or injury, robust and lively, uniform specifications. Before stocking, it is best to wash with 3% salt water for 10 minutes. After the beginning of spring, it is advisable to choose a sunny day for stocking.

4, baiting is reasonable: because the loach is omnivorous fish, breeding, in addition to fertilization to cultivate natural bait, can be appropriate to feed some animal bait, such as snails, earthworms, silkworm chrysalis powder, animal offal, etc.; can also be fed part of the plant bait, such as rice bran, soybean cake, rice, vegetable leaves, etc.. Its baiting amount; 1% of the total amount of loach in August, 4% in April-June, 10% in July-August and 4% in September-October. Generally to the end of autumn and early winter, loach into hibernation, can ask the pool to apply some base fertilizer, so that its insulation over winter. Baiting should be set up bait table, so as not to waste, at the same time, the bait should be moderate, it is desirable to eat within 2-8 hours is good, otherwise it will be bloated to death.

5, change the new water diligently: we should always observe the water quality changes, generally the water color is suitable for yellow-green, to prevent the pool water from over-fertilization. If you find the loach sometimes scurry out of the water, which indicates a lack of oxygen in the water, should be replaced with new water. Especially in thunderstorms, hot weather, it is more important to inject new water to increase oxygen. If the conditions, available oxygen aerator oxygen, in order to prevent the death of the pool.

6, anti-metallurgical disease: loach common diseases are water mold disease and fin rot. If these diseases occur, we can use 10-15 micrograms of antimicrobial solution per milliliter to wash for 10 minutes.
