The paper reports the process and results of studies on artificial propagation and larva-rearing of Fugu flavidus done in Fujian Fisheries Research Institute in 2004~2005.In spring,when the water temperature is above 20℃,mature parent fishes are induced to spawn by injecting DOM,LHRH or HCG,mixedly or respectively.The dosage of hormone depends on the sexual maturity of the parent fishes.The zygotes incubated under the condition of seawater salinity 20.0~30.0 and temperature 20.0~25.0℃.It took 144~156 hours for larvae to hatch.During the studies,about 60.8×106 larvae were obtained.,and all larvae were raised in outdoor ponds or indoor concrete pools.At the end,about 16.85×106 fingerlings,which mean total length is 4.43 cm and mean body weight is 1.98 g.The survival rate is 27.7%.The key technologies on parent fishes raised,inducing to spawn,incubation and pre-larvae and post-larvae raising also have been discussed in the present paper.

This paper reported the result of artificial breeding of Fugu xanthopterus by Fujian Fisheries Research Institute in 2005.At water temperature 18.6~20.2℃ and salinity 27.3~28.6,the effective time was about 39~49h;At water temperature 18~21℃ and salinity 27.3~28.6,the zygote was incubated for 120~216h;At water temperature 18~21℃ and salinity 15.0~30.0,the survival rate of larva was 69.7% after 13d's breeding;At water temperature 26.0~29.0℃ and salinity 15.0~30.0,after 300,000 juveniles were bred in outdoor ponds for 50d,50,000 fries with average length of 5.4cm and average weight of 1.1g were obtained.The survival rate was 16.7%.
