Abstract:The present paper deals with the organs development of blunt snoutbream (Megalobrama amblycephala).Specimens were collected from Qing Pu Fre-shwater Fishfarm of Shanghai during May to Nov., 1985. The morphogensis of larvaewere observed continuously on living specimens. The total and standard body length,head length, greatest depth, diameter of eye and otic capsule, and intestine lengthwere all measured. In the development of the digestive system, the increase of relative length of in-testine reaches to 228% when standard body length is 59 .8mm. Teeth andgill rakersgradually increase in number. The respiratory organ at first bears a few buds on eachgill arch, then a series of gill filaments formee and divided into feather-like gilllamallae, the lamallae increase rapidly in number. The air bladder has threechambers, at first the midbober grows out from the oesophagus, and afterwardthe anterior and posterior ones develop. Olfactory and otio sense organs complete afterhatching. The morphological characteristies of larval development can be divided into A-Gstages. Stage A: The larva has just hatched, bearing a pear-shaped yolk sac, Totallength is 4.0-6.2mm. Stage B: The yolk sac reduced, air bladder inflated, fin-folddifferentiated, TL 6.2-7.0mm. Stage C: Yolk is assimilated, TL. 7.0-8.8mm. StageD:Finrays appeared in dorsal, eaudal and anal fin, TL 8.8-16.6mm. Stage E: Pelvicfins with unossified rays, TL 16.6-22.0mm. Stage F: Pelvic fins with ossified rays,scales appeared on sides of the body, TL 24.0-35.0mm. Stage G: Body is fully scaled,TL over 35mm.
Keywords:Blunt snout bream (Megalabrama amblycephala)  Organs development  Stages of development
