Second, how to raise tropical fish fry?

1. Water injection by stages. In order to meet the requirements of activity space, water quality and nutrition of fish fry in different stages, water injection by stages is an effective measure to improve the survival rate and growth rate in the process of fish fry cultivation. The specific method of operation is: the shallow water goes into the pond, that is, the water depth is about 0.6 meters when the fish flowers go into the pond, and then according to the water color and the growth of fish fry, water is injected once every 4-5 days, each time 10-20 cm, and the water depth is finally stable at 1.2-1.5 meters.

2. Daily management. Patrol the pond once every morning and evening, carefully observe the water quality, fry activity and eating, timely fish out sick fish, dead fish, immediately check, if diagnosed fry disease, should take necessary prevention and control measures. In addition, check whether there are loopholes in the dike ridge, whether the drain is in good condition, and pay attention to escape prevention.
