The accurate definition of population units (stocks) and local adaptation are the cornerstones of fishery management. Unfortunately, this knowledge is unknown mainly for abalone species in the Northeast Pacific, where stocks have failed to recover. The pink abalone (Haliotis corrugata) is a fishing resource on the western coast of the Baja California Peninsula (BCP) and is currently catalogued as diminished with a recovery trending pattern. This research determined if the biological units matched the administrative and stock assessment units along the west coast of the BCP and the implications for fishery management. To test this hypothesis, a double digest restriction site-associated DNA sequencing approach was used to generate 1 733 neutral and 6 putative outlier loci for population genomic analysis. Neutral markers detected a smooth partition in two regional groups, the southern (San Juanico, La Bocana, Bahía Asunción, Puerto Escondido, Punta Eugenia, and Natividad Island) and northern regions (Cedros Island, Faro San José, San Jerónimo Island, and Guadalupe Island). Putative outlier loci indicated evident differentiation of those groups. The population subdivision at 28° latitude with both marker types was related to a biogeographic boundary. Results did not support the current administrative zones of pink abalone fisheries and contrasted with genetic homogeneity reports in the region.

粉红鲍鱼（Haliotis corrugata）的中性和适应性种群结构：渔业管理意义

种群单位（种群）的准确定义和当地适应是渔业管理的基石。不幸的是，这些知识主要是在东北太平洋的鲍鱼物种中未知，那里的种群未能恢复。粉红鲍鱼 (Haliotis corrugata) 是下加利福尼亚半岛 (BCP) 西海岸的一种渔业资源，目前被归类为减少，并呈现复苏趋势。这项研究确定了生物单位是否与 BCP 西海岸的行政和种群评估单位相匹配，以及对渔业管理的影响。为了验证这一假设，使用双酶切限制性位点相关 DNA 测序方法生成 1 733 个中性和 6 个假定的异常值基因座用于群体基因组分析。中性标记在两个区域组中检测到平滑划分，南部（圣胡安尼科、拉博卡纳、巴伊亚亚松森、埃斯孔迪多港、蓬塔尤金尼亚和纳蒂维达岛）和北部地区（塞德罗斯岛、法鲁圣何塞、圣热罗尼莫岛和瓜达卢佩岛）岛）。假定的异常位点表明这些组有明显的差异。具有两种标记类型的 28° 纬度的人口细分与生物地理边界有关。结果不支持当前的粉红鲍鱼渔业行政区，并与该地区的遗传同质性报告形成对比。假定的异常位点表明这些组有明显的差异。具有两种标记类型的 28° 纬度的人口细分与生物地理边界有关。结果不支持当前的粉红鲍鱼渔业行政区，并与该地区的遗传同质性报告形成对比。假定的异常位点表明这些组有明显的差异。具有两种标记类型的 28° 纬度的人口细分与生物地理边界有关。结果不支持当前的粉红鲍鱼渔业行政区，并与该地区的遗传同质性报告形成对比。
