Q: when is the best time for fish culture to release fish fry?

Answer: in general, the air temperature and water temperature in spring are relatively low, and the activity ability of fish fry is low. In the process of fishing, transportation and release, it is necessary to avoid fish body injury or less injury, and improve the survival rate. Conditional live, as early as possible to release fish fry, promote fish fry to eat early, prolong the effective growth period of fish throughout the year, which is conducive to increase production. But not blindly early. It is best to release fish fry when the water temperature is stable and above 18 degrees. The release of fish fry is easy to do this early, and it is better when the water temperature rises to 8-12 degrees after sting. In the northern region, Shuihua Xiatang is generally better from the end of April to mid-May, and Wuzai Xiatang is usually from May to June. If the water temperature is too early or unstable, the survival rate will be low. If it is too late, it will delay the growth period and affect the growth of the whole year.
