The Haemulon plumieri is a typical reef-associated and tropical species found in warm and temperate waters of the Western Atlantic. Due to the large fishing effort directed to H. plumieri, the knowledge about its reproductive biology is essential for correct stock management and conservation. The aim of this study was to characterise reproductive biology with a focus on its seasonal variation of gonadal maturation stages, first maturation size and fecundity. Specimens were monthly collected and a total of 119 females and 136 males were analysed. The reproductive cycle of Haemulon plumieri is seasonal, with higher activity between March and May. Size at first maturity (L50) was estimated at 16.86 and 18.55 cm for females and males, respectively. The total fecundity ranged between 17,816 and 120,333 mature oocytes per female and relative fecundity was 235 ± 63 oocyte.g-1 whereas batch fecundity varied between 20 and 25% from total fecundity. Since the species is widely caught, we suggest a closed season from March to May and to establish a minimum catch size of 18.5 cm for both sexes, since there is no evident sexual dimorphism.
黑锯眶雀鲷是一种典型的与珊瑚礁相关的热带物种，分布于西大西洋的温暖和温带水域。由于针对黑锯眶雀鲷的捕捞力度较大，了解其生殖生物学对于正确的种群管理和保护至关重要。本研究的目的是描述其生殖生物学特征，重点关注性腺成熟阶段的季节变化、初次成熟大小和繁殖力。每月采集样本，共分析了119只雌性和136只雄性。黑锯眶雀鲷的生殖周期是季节性的，3月至5月间活动更为频繁。雌性和雄性的初次成熟体长（L50）分别估计为16.86厘米和18.55厘米。每只雌性的总繁殖力在17,816至120,333个成熟卵母细胞之间，相对繁殖力为235±63个卵母细胞·克-1，而分批繁殖力占总繁殖力的20%至25%。由于该物种被广泛捕捞，鉴于没有明显的两性异形，我们建议3月至5月为禁渔期，并为两性设定18.5厘米的最小捕捞体长。
