1. Loach is a warm water fish, living in the range of 15-30 ℃, feeding in the optimal 24-27 ℃ water temperature range.

2. Male and female loach can be identified by their appearance: male head pointed, pectoral fins narrow and long, the body and the tail end of the same thickness, the tip of the tail upturned fins at the base of a bony lamellae; female head was oval flat type. Female loach spawning power is extremely strong, a female loach early summer to early fall can produce more than 4,000 eggs, generally 2-3 times a year, more than 10,000 eggs.

3. Because loach is omnivorous fish, so no matter rice bran, or wheat, fly maggots can be fed as bait, generally three times a day. Feeding amount is generally determined according to the feeding situation.

4. loach feeding process, can be appropriate to supplement some organic fertilizer, but in the fertilization, must not be too much too often, and to change the pool water, generally 10-15 days to change the water once.

5. To catch loaches, first of all, the pool water should be drained, take the approach of catching big and leaving small, to ensure that there is a certain number of loach seedling in the pool, which is conducive to the succession of breeding and high yield.

6. With the growth of loach species, gradually deepen the water level to the depth it should be, usually a little shallow, hot and high temperature can be deepened a little, and often injected into the new water to maintain a good water environment.

7. At the end of fall and early winter, the water temperature drops to 10 ℃ ~ 15 ℃, the loach feeding is reduced, you can fish.
