摘　　要：为阐明花鲈鳃与鳔器官的发生机制,实验采用连续组织切片技术接合形态学观察 对出膜后1~45 d花鲈胚后发育的鳃与鳔器官的发生、发育过程进行了系统的观察与研 究。结果显示,花鲈仔稚鱼鳃的胚后发育分为4个阶段,鳃原基出现期(0~3 d)、鳃丝分 化期(4~14 d)、鳃小片分化期(15~25 d)与鳃器官完善期(26~45 d)。在水温15~18 °C条件 下,花鲈孵化后的第1天,鳃原基出现;孵化后的第15天,仔鱼假鳃上分化出鳃小片结 构;孵化后的第25天,仔鱼各鳃弓上均分化出鳃小片结构;孵化后的第45天,稚鱼鳃结 构发育完全,与成鱼相同。组织学观察结果显示,花鲈鳔器官的发育时期分为形成、扩 张、充气和退化4个阶段。花鲈初孵仔鱼未出现鳔原基,在孵化1 d后,仔鱼出现鳔原 基,5 d后仔鱼鳔开始扩张,11 d后仔鱼鳔充气完成,13 d后仔鱼鳔开始退化。In order to elucidate the development of gill and swim bladder of Lateolabrax maculatus, in this study,histological section technique and morphological observation were used to systematically study the occurrence anddevelopment of gill and swim bladder of L. maculatus from 1 to 45 days. The results showed that the postembryonicdevelopment of the gill of L. maculatus juvenile can be divided into four stages, including theappearance period of gills primordium (0-3 d), the differentiation period of filaments (4-14 d), the differentiationstage of lamella (15-25 d) and the completed period of gills (26-45 d). At the water temperature of 15-18 °C, theprimordial filament was observed at 1 d, and the lamella structures formed from the pseudobranch were firstlyobserved at 15 d. After 25 d, the lamella structures were widely distributed in each juvenile gill arch. After 45 d, awell-developed gill structure of juvenile fish was clearly detected and identical with adult fish. According to theobservation results, the development stages of the swim bladder organ of L. maculatus were divided into fourstages: formation, expansion, aeration and degeneration. The appearance of swim bladder primordium was notobserved on the newly hatched larvae, but after being hatched for 1 day. After 5 d, the swim bladder cavity oflarvae became larger and longer. The inflation of the larvae swim bladder was completed at 11 d. Finally, thedegeneration of swim bladder of larvae began to occur after 13 d.
