| 摘 要： | 参照鮨科鱼类胚后发育时期划分的一般方法，结合豹纹鳃棘鲈的形态特征将其胚后发育时期划分为仔鱼期（分卵黄囊期仔鱼和后期仔鱼）、稚鱼期和幼鱼期，并对各时期的形态特征进行了描述。记录了各时期的形态特征，豹纹鳃棘鲈体型修长，幼鱼通体红色，在鱼体上有数列排列整齐的蓝色或黑色斑点；在早期发育阶段第二背鳍棘和腹鳍棘的绝对平均长度可达13．12mm和10．19mm，而臀鳍发育较慢，当腹鳍棘和第二背鳍棘开始回收时其臀鳍棘才开始长出。

| Abstract: | The general practice on division of the postembryonic development period of osteichthyes was used as reference, based on the morphology characteristic, the postembryonie development period of Plectropomus leopardus was divided into larval stage （including yolk-sac larva and late-stage larva）, juvenile stage and young fish stage, and the morphology of the fish during its various development period was described in detail. The type of build of P. leopardus was slender, and the color of the all juvenile fish body was red. There were the neat blue color or the black spots on the body. In the early developmental stage, the average length of the ventral fin thorn and the second dorsal fin thorn attained 13.12 mm and 10.19 mm respectively, but the growth speed of the anal fin was so slow that its anal fin thorn start growing up when the ventral fin thorn and the second d.rsal fin thorn of the fish degenerate. |
