Anisotremus interruptus is a widely distributed and commercially important species in the Eastern Pacific. A multi-year research on the reproduction of this species was carried out in coastal waters of Jalisco, Mexico. For this purpose, monthly samples were gathered with gillnets of different mesh sizes from 1998-2008. A total of 1090 individuals were collected with a total length range between 15.6-61.0cm. Significant differences from expected 1:1 ratio were found for sex ratios in the total sample and for each size class, but not when comparisons among months and years were done. Temporal variations of the gonadosomatic index and proportions of maturation stages suggest that the main reproductive period is from February to May, although some less intensive spawning events were observed in other months. Seven stages of oocytes development were identified. Oocytes in different stages of development were identified in ovaries classified as mature, suggesting an asynchronic type of gonad development. Mean maturation length (L50) was 31.0 for females and 29.7cm for males. The internal organization of testes is of lobular type.
间带异孔石鲈是东太平洋一种分布广泛且具有重要商业价值的物种。对该物种的繁殖进行了一项在墨西哥哈利斯科州沿海水域开展的多年研究。为此，在1998年至2008年期间，用不同网目的刺网每月采集样本。共采集了1090个个体，全长范围在15.6 - 61.0厘米之间。在总样本以及每个体长组中，性别比与预期的1:1比例存在显著差异，但在按月份和年份进行比较时则不存在。性腺指数和成熟阶段比例的时间变化表明，主要繁殖期为2月至5月，不过在其他月份也观察到一些强度较小的产卵事件。确定了七个卵母细胞发育阶段。在被归类为成熟卵巢中发现了处于不同发育阶段的卵母细胞，这表明性腺发育为异步类型。雌性的平均成熟体长（L50）为31.0厘米，雄性为29.7厘米。精巢的内部结构为小叶型。
