点带石斑鱼仔、稚、幼鱼的形态观察

Observation on the Morphology of the Larva, Juvenile and Young Fish of Epinephelus malabaricus(Bloch & Schneider)

根据点带石斑鱼胚后发育过程中卵黄囊的消失、鳍的形成、鳞片的出现等形态特征变化 ,参照国内外对硬骨鱼类胚后发育时期划分的一般方法 ,将点带石斑鱼的胚后发育划分为仔鱼期 (含卵黄囊期仔鱼和后期仔鱼 )、稚鱼期、幼鱼期 ,并对各个发育时期的形态特征进行了较为详细的描述 ,记录了各个发育时期的体长。

According to the morphological changes appearing in the postembryonal development of Epinephelus malabaricus (Bloch & Schneider), such as the disappearance of yolk sac, the formation of fins and the appearance of scales etc., and with reference to the general practice home and abroad on division of the postembryonal development period of osteichthyes, the authors divided the postembryonal development period of Epinephelus malabaricus (Bloch & Schneider)into larval stage (including yolk sac larva and late stage larva),juvenile stage,and young fish stage.This article presented a detailed description of the morphology of the fish in its various development periods,and recorded the length, weight and growth of Epinephelus malabaricus (Bloch & Schneider)in its various development periods.
