The result of the experiment showed that the embryos of flat-bream were relatively sensitive to the change of the temperature, and its optimal temperature for the development was 21-4℃.展开更多

The larva were fed with rotifers and copepods. Thirty two days later, postlarva were reared, with a survival rate of 0.8%.While the juvenile were fed with minced shrimp and fish, as well as small shrimp and fish, their survival rate was 100% After nine months of seed breeding, young fish attained the total length of 180mm on the average, and the weight was 100g.展开更多
