Abstract

Climate change has significantly affected the Curonian Lagoon, the largest coastal lagoon in Europe, which is of great economic importance to fisheries and tourism. We modeled how environmental factors and fisheries affected recruitment and subsequent catches of pikeperch (Sander lucioperca L.) and common bream (Abramis brama L.) in the lagoon. Recruitment, catch per unit effort (CPUE), environmental variables, and fishery catch, and effort were used to construct Bayesian belief networks (BBNs) for both fish species. Catches of pikeperch and common bream depended more on fishing effort than recruitment. Environmental factors (temperature and riverine discharge) were only weakly related to catches of pikeperch and common bream. Changes in salinity and temperature are expected to have only minor direct effects on populations of pikeperch and common bream.

渔业或气候变化是否推动了浅层富营养化泻湖的商业捕捞？

气候变化对库尔尼泻湖（Curonian Lagoon）产生了重大影响，库尔尼泻湖是欧洲最大的沿海泻湖，对渔业和旅游业具有重要的经济意义。我们模拟了环境因素和渔业如何影响泻湖中棘鲈（Sander lucioperca L.）和鲷鱼（Abramis brama L.）的招募和随后的捕捞。利用招募量、单位努力渔获量（CPUE）、环境变量、渔获量和渔获量构建两种鱼类的贝叶斯信念网络（bbn）。刺鲈和鲷鱼的捕获量更多地取决于捕鱼努力而不是招募。环境因子（温度和河流流量）与鲈鱼和鲷鱼的捕获量相关性较弱。盐度和温度的变化预计只会对鲈鱼和鲷鱼的数量产生轻微的直接影响。

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.
