The water depth of 1 meter is suitable for raising crucian carp, carp, grass carp, silver carp, bighead carp, anchovy, herring and so on. These fish are common economic fish, and they are widely distributed in China. They can be raised in various areas, and the difficulty is not high. If it is family fish farming, the water of 1 meter is relatively deep, so it is impossible to raise too small fish. It is necessary to raise large ornamental fish such as arowana, map fish and Luohan fish.

1. Disinfection of fry: Fish in a 1-meter-deep fish pond usually starts from raising fry. In order to ensure the health of fry, they need to be disinfected before being put into use. The disinfection method is very simple. Potassium permanganate can be used, and after being mixed with dissolved oxygen with lower concentration, the fry can be soaked in it for a period of time, and then taken out and stocked in the fish pond.

2. Release density: Because 1 meter is not very deep, the release density should not be too high, otherwise the fish will crowd each other, which is very unfavorable to their growth. However, in order to improve the efficiency of fish farming, the density should not be too small. Usually, an acre of fish pond can raise 8000-12000 fish.

3. Daily management: In the daily feeding process, the fry should be fed regularly and quantitatively, usually three times a day, or properly fertilized before stocking. The fertilizer will make plankton multiply in large numbers, thus providing food for the fry. When you grow up, you will start feeding in separate ponds.
