In this paper, the influence of temperature on the embryonic developments of flat-bream (Rhabdosargus sarba) is reported.The parent fish of the flatbream cultured in the pond were induced by using HCG and LRH-A and the fertilized eggs produced through artificial propagation were reared under five different water temperatures. 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℃.
The preliminary result of study on the artificial seed breeding of garrupa, Epinephelus akaara, larva obtained from the artificial propagation was report. 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.
