Abstract

We evaluated the feasibility of classifying ommastrephid and loliginid squid species by statolith shape analysis into fisheries management units or stocks. Statoliths of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) were studied from multiple areas of the North East Atlantic and Northern Mediterranean Sea during 2021–2022. I. coindetii and L. forbesii individuals were categorized into multiple stocks across the areas studied. Stocks migrating between fishing areas as well as multiple stocks in the same area, as identified for L. forbesii in this study, need to be considered for sustainable fisheries management.

通过统计形状分析辨别两种欧洲鱿鱼（Illex coindetii 和 Loligo forbesii）的种群

我们评估了通过统计石形状分析将乌贼和鱿鱼物种划分为渔业管理单元或种群的可行性。在 2021-2022 年期间，我们对东北大西洋和地中海北部多个区域的 Illex coindetii (Verany, 1839) 和 Loligo forbesii (Steenstrup, 1856) 的体片进行了研究。I. coindetii 和 L. forbesii 个体在研究区域内被划分为多个种群。在可持续渔业管理中，需要考虑在渔区之间洄游的种群以及同一地区的多个种群，如本研究中发现的福氏鳞鱼。

期刊介绍： Fisheries Management and Ecology is a journal with an international perspective. It presents papers that cover all aspects of the management, ecology and conservation of inland, estuarine and coastal fisheries. The Journal aims to: foster an understanding of the maintenance, development and management of the conditions under which fish populations and communities thrive, and how they and their habitat can be conserved and enhanced; promote a thorough understanding of the dual nature of fisheries as valuable resources exploited for food, recreational and commercial purposes and as pivotal indicators of aquatic habitat quality and conservation status; help fisheries managers focus upon policy, management, operational, conservation and ecological issues; assist fisheries ecologists become more aware of the needs of managers for information, techniques, tools and concepts; integrate ecological studies with all aspects of management; ensure that the conservation of fisheries and their environments is a recurring theme in fisheries and aquatic management.
