Developmental process of gonad in the white-streaked grouper and the honeycomb grouper was investigated using physiological and histological methods. In addition, spawning migration and return behavior to feeding ground were observed using a biotelemetry method. In this study, we have following results. 1) Both species have a reproductive endocrine system associated with lunar rhythm and gonadal development and spawning are controlled by the endocrine system. 2) In female fish, final oocyte maturation was not observed in the feeding ground. 3) These groupers move to spawning ground from the feeding ground for spawning. After spawning, fish retune to the feeding ground. 4) The rearing water of male has a strong effect on induction of final maturation in female. 5) It appears that the final maturation in female is completed by receiving the maturation-inducing pheromone from male in the spawning ground. These results are useful information for conducting resource management in groupers.

用生理学和组织学方法研究了白条纹石斑鱼和蜂窝石斑鱼性腺的发育过程。此外，用生物遥测法观察了产卵迁移和返回取食地的行为。在这项研究中，我们有以下结果。1)两个物种都有与月相节律相关的生殖内分泌系统，性腺发育和产卵受内分泌系统控制。2)雌鱼在取食地未观察到卵母细胞最终成熟。3)这些石斑鱼从觅食地迁移到产卵地产卵。产卵后，鱼返回觅食地。4)雄鱼的饲养水对诱导雌鱼最终成熟有较强的影响。5)雌鱼的最终成熟似乎是在产卵地接受雄鱼诱导成熟的信息素完成的。这些结果为石斑鱼资源管理提供了有益的信息。
