Research Abstract

1. The low tcmperature tolerance of embryo of red sea bream and flounder were docreased at stage of clcavage, early blastula, cmbryo appearance and blastopore closure, respectively. 2. Thyroid hormone plays the roles of an inducer in the morphological and bchavioral transformation from post-larva to juvenile. 3. Optic tectum and cerebellum of red sea bream begin to develop on 30-37th day after hatching, although telencephalon is still undeveloped on the 42nd day. 4. Phospholipase A_z was demonstrated immunohistochemically in mucosa of the upper intestine of post-larva and adults of red sea bream. 5. The molecular weight of phospholipase A_z purified from homogenates of red sea bream was cstimated to be about 21,000. 6. A significant reduction of maximal isometric twitch tension in lateral musculature of chum salmon fry was caused by trypto-phan deficiency in the dict. 7. The precceding twitch tension of both red sea bream and black sea bream juveniles jncreased linearly their body leng … More th. 8. Red sea bream fry acquired a behavioral tendency to avoid the averssive electro-convulsive shocks in response to start of lighting signaling an onset of the ECS. 9. Bacterial flora in alimentary tract of flounder, tiger puffer, rockfish and red grouper at their larval and juvenile stages was studied in re-lation to the microflora of their diets and ambient waters. 10. Rockfish juveniles often suffer-ed from vibriosis caused by Vibrio ordalii and the efficacy of immersion vaccination against the vibriosis was confirmed by artificial challenge tests. 11. After released into the pond(7,500 m^2), the young red sea bream which had been intensively produced by the supply of artificial diet didn't survive longer than the extensively produced group feeding on natural organisms also. 12. Some differences in energy accumulation were found among red sea bream seedlings produced by different rearing systems. 13. The period just after release and over-wintering might be severe to the released red sea bream seed, then, in terms of resistance to starvation, optimum size for release was defined 5cm in total length.
