摘　　要：本文对状黄姑鱼的胚胎和仔、稚鱼各发育阶段的形态特征进行了描述。绝状黄姑鱼的受精卵为圆球形浮性卵，无色透明。在水温20～23℃，盐度26～30的条件下，经24h35min陆续孵出仔鱼。胚胎发育分为26期。初孵仔鱼至孵化后4日龄为仔鱼前期；孵化后5～22日龄为仔鱼后期；孵化后23～32日龄为雅鱼期；孵化后33日龄进入幼鱼早期。仔、稚鱼培育水温18～28C，盐度20～30。仔鱼2日龄稍开口，3～4日龄为混合营养阶段，是仔鱼的主要危险期。The morphological characteristics of early development of Nibea miIYhthioides Chu, Lo &Wu are described. The fertilized egg is spherical in shape,transparent and buoyant' The lar-vae began hatching 24 h and 35 min after fertilization at water temperatures of 20～23℃ andsalinities of 26～30. Embrjonic development can be devided into 26 stages. The prelarvalstage developed from newly hatched larva of 4 days after hatching,the postlarval stage devel-oped,during 5～22d after hatching;the juvenile stage developed,from 23 to 32d after hatch。ing. The juvenile reached the early young stage 33d after hatching. The larvae and juvenileswere reared at water temperatures of 18～28℃ and salinities of 20～30. The 2d larval slightly opened. The mixed endogenous and exogenous nutrition occurred in 3～4d after hatching,or rather the most dangerous period.
