How to choose stocking time

The stocking time is usually around mid-April and the pond water temperature is stable above 14°C, but it should be sooner rather than later. Early release has two advantages: First, the temperature, water temperature is relatively low, less fry activity, high relative survival rate; second, it can relatively enhance the fish breeding time, thereby increasing fish breeding specifications. When stocking, first use the net to put the fish species in a relatively small range for domestication and feeding, then do the timing, fixed point, quantitative feeding, until the fish form a conditional reflex, then remove the seine net, and normal breeding. It usually takes about a week from stocking to normal food and eating. The timing of seedling release of fingerlings should be based on the size of the fry, and the method of stocking density operation is similar to that of adult fingerlings, but the time for domestication and feeding is longer. In the later period of seedling cultivation, the ponds in the plastic greenhouses were counted for winter. When the adult fish is reared the following year, it will be placed in the pond again.
