Abstract

Marine fisheries management models have traditionally considered biological parameters and geopolitical boundaries. The result is the existence of fisheries management units that do not match genetic populations. However, this panorama is changing with the contribution of genetic and genomic data. Pagellus bogaraveo is a commercially important sparid in the northeast Atlantic, with three stock components being considered by ICES: the Celtic Sea and Bay of Biscay, Atlantic Iberian waters and the Azores. The northern stock collapsed (1975–1985) and is essential to characterize the genetic makeup of the species, particularly in the Iberian Peninsula, where it is managed as a single stock. The mitochondrial control region was used to screen the intraspecific diversity and population structure of individuals from six locations across the species range. The genetic diversity found is similar among sites, and there is differentiation between the Azores and the remaining locations.

摘要

海洋渔业管理模型传统上考虑了生物参数和地缘政治边界。结果是存在与遗传种群不匹配的渔业管理单位。然而，随着遗传和基因组数据的贡献，这种情况正在发生变化。椴树是东北大西洋的重要商业鱼种，ICES 考虑了三个种群组成部分：凯尔特海和比斯开湾、大西洋伊比利亚水域和亚速尔群岛。北部种群崩溃（1975-1985 年）并且对于表征该物种的遗传构成至关重要，特别是在伊比利亚半岛，它作为单一种群进行管理。线粒体控制区域用于筛选物种范围内六个位置的个体的种内多样性和种群结构。发现的遗传多样性在地点之间相似，亚速尔群岛与其余地点之间存在差异。
