The best water depth for raising crayfish is about 1.5 meters. It is not good to raise crayfish when the water level is too deep or too shallow. If the water is too deep, it will not only be inconvenient to catch, but there will also be crayfish. Phenomenons such as hypoxia and too shallow water are not conducive to the growth and reproduction of crayfish.

Different seasons have different requirements for water levels. If it is March-April, the water level of the crayfish breeding pond needs to be maintained at 0.6-1.0 meters. This will help the water plants, plankton, and screws in the crayfish breeding pond. Waiting for growth and molting of juvenile shrimps.

After May, the temperature gradually rises. At this time, the water temperature will also steadily increase, and the water level needs to be gradually increased to about 1.2 meters.

In July, as the temperature gradually rises, the water level needs to be raised to about 1.5 meters to prepare for the crayfish to survive the high temperature weather.

After September, the water level is controlled at 0.8-1.0 meters, which will help fertilized eggs hatch and free up part of the breeding pond bank, leaving enough space for crayfish to burrow for eggs.

In mid-to-late November, the temperature gradually drops, and the water level needs to be gradually raised according to the temperature. When the temperature drops below 10°C, the water level needs to be gradually raised to 1.2-1.5 meters to provide enough bottom layer for the young shrimps to survive the winter. Water surface temperature.
