Abstract:The short-snout icefish, Salangichthys(Neosatanx)tangkahkeii taihuensis Chen, is one of commercial fishes in Taihu Imke.Investigation on the embryonic development of this sort of fish was made during the year 1981-1983.The ovarian egg of this fish is demer, colorless, spherical or spheroidal, measuring 0.53-0.82mm in diameter, with extem a1 filaments.The bends in the lake is the spawning ground.Fertilized egg hatching takes 312 hours 15 minutes at the water temperature of 5.9-14.2℃ The just hatched larva is 244mm in tota1 length.with the melanopho rea around the aDus open.Them yotome numberis 42+13:55 In 3 days, larva's mouth begins to open and the air bladder is abounded by gas.The string melonophorss are scattered on the yolk and above the ventral fin fold In 5 days.the yolk is al-most entirely consumed and the 1arve attained 4, 60mm in total 1enth.In 9 days.the yolk is en-tirely consumed.In 12 days.the lalva dies off.It has been found that the fertilized eggs could be used in transplanting.As to lakes and res-ervoirs where there is no ice fish, great economic benifits can be achieved after the transplantation of Salangichthys(Neosalanx)tangkahkeii taihuensis Chen succeeds.
