Abstract Shoal bass Micropterus cataractae are endemic to the Apalachicola River system in Alabama, Georgia, and Florida, USA. Despite maintaining popular fisheries, little is known about their biology and ecology. Fecundity of this species was estimated from the lower Flint River, Georgia, to better understand egg production of this species and relation with length and weight. Further, these data were used to estimate the spawning potential ratio (SPR) of this population under the current 305-mm minimum-length limit (MLL) and a more restrictive 381-mm MLL. An age-structured model was used to examine changes in yield and SPR across a range of exploitation at three levels of natural mortality. Fecundity of shoal bass ranged from 909−35,502 oocytes with a mean estimate of 10,424 ± 1089 (SD), and increased with length (r2 = 0.46; P

美国乔治亚州弗林特河下游浅滩鲈 Micropterus cataractae 的繁殖力和产卵潜力比

摘要 浅滩鲈 Micropterus cataractae 是美国乔治亚州阿拉巴马州和佛罗里达州阿巴拉契科拉河系统的特有种。尽管维持着受欢迎的渔业，但对其生物学和生态学知之甚少。该物种的繁殖力是从乔治亚州弗林特河下游估算的，以更好地了解该物种的产蛋量以及与长度和重量的关系。此外，这些数据用于估计该种群在当前 305 毫米最小长度限制 (MLL) 和更严格的 381 毫米 MLL 下的产卵潜力比 (SPR)。年龄结构模型用于检查在三个自然死亡率水平的一系列开发中产量和 SPR 的变化。浅滩鲈的繁殖力范围为 909-35,502 个卵母细胞，平均估计值为 10,424 ± 1089 (SD)，并且随着长度的增加而增加 (r2 = 0.46; P
