2. Because loach is an omnivorous fish, rice bran, wheat and maggots can be used as bait, usually three times a day. The feed rate is generally determined by the feed intake.

3. In the feeding process of loach, some organic fertilizer can be properly supplemented, but the fertilization must not be too frequent, and the pool water should be changed frequently, usually once every 10- 15 days.

4. To catch Misgurnus anguillicaudatus, firstly, the water in the pond should be drained, and the method of catching large and releasing small should be adopted to ensure that there is a certain amount of loach seedlings in the pond, which is beneficial to secondary culture and high yield.

5. With the growth of loach species, gradually deepen the water level to an appropriate depth, which is shallow at ordinary times and deep at hot and high temperatures, and often inject new water to maintain a good water-holding environment.

6. In late autumn and early winter, when the water temperature drops to 10℃ ~ 15℃, the food intake of loach decreases and it can be fished.
