Problems solved by technology

At present, large-scale artificial breeding of yellow croaker has been carried out in Fujian and Zhejiang in my country, but the special compound feed for juvenile yellow croaker has not been developed yet, and the breeding feed mainly uses rotifers, artemia and copepods, etc. Feeding yellow croaker with the existing seawater larvae and juvenile feed has a series of problems such as incomplete nutrition, poor palatability, and low absorption and utilization rate, which seriously affects the survival rate of croaker and restricts the further development of its aquaculture industry.
