摘　　要：采用活体性腺观察和组织切片法对广西北海自然海区波纹巴非蛤的性腺周年发育进行了初步研究 ,并以波纹巴非蛤滤泡中生殖细胞所处的主要发育阶段作为性腺发育的分期标准 ,将性腺发育过程分为 :休止期、增殖期、生长期、成熟期、排放期和滞留退化期等 6个时期 ,同时揭示了在广西北海自然海区波纹巴非蛤的性腺发育一年只有一个周期 ;此外 ,还发现雄性早熟现象 .By observing the seasonal changes of gonad of live shellfish and the changes of gonad on histological sections,the yearly development of the gonad of the clam Paphia (Paratapes) undulata (Born) in the sea area of Beihai, Guanxi was studied.Taking the developmental status of the gametes in follicles as the main characteristics,the authors thought that the development of the gonad could be devided into six stages for both male and female,ie,resting stage,proliferating stage,growing stage,maturing stage,spawaing stage,and degenerating stage.Meantime,it was revealed that the gonadal development of the clam has only one cycle in a year in Beihai area. In addition, some precocity were found.
