The author studied the artificial inducement for spawning,the hatching of fertilized egg, the bait series selection, the zoology temperament of larva fish,juvenile and young fish of Inimicus japonicus,also conducted the consecutive observation of the embryo growth of Inimicus japonicu. The research for artificial breeding acquired (110.25) thousand young Inimicus japonicus after 35 days, the average hatching rates of fertilized egg was (62.9%),the average survival rate of breeding was 30.2%, by artificial hastening in using the hormone LRH-A and HCG,hatching of fertilized egg in artificial and breeding to the young fish.The result shows the hatching rate of Inimicus japonicus fertilized eggs will increase with the increasing of the seawater salinity; rotifer,artemia and copepodid are high quality bait series; larva fish,juvenile and young fish have two death peak periods, and quality of water is a main factor influencing the survive rates of breeding.
