What is the best time to release fry when raising fish?

A: Generally, in spring, the air and water temperatures are relatively low, and the fry have low activity levels. During catching, transport and release, it is necessary to avoid injuring the fish or to minimize injury, so as to increase the survival rate. If conditions allow, release the fry as early as possible, to encourage the fry to start feeding early, extend the fish's effective growing period for the whole year, and help increase output. But do not move it earlier blindly. It is best to stock the fry when the water temperature is stable and has reached above 18 degrees; for fingerlings, the stocking time can be slightly earlier, and it is better to stock them after Awakening of Insects (Jingzhe) when the water temperature rises to 8-12 degrees. In northern regions, for newly hatched fry going into the pond, late April to mid-May is generally better, and for larger fry going into the pond, generally May to June. If it is too early, the water temperature is low or unstable, and the survival rate will be low; if it is too late, it will delay the growing period and affect the whole year's growth.
