商业捕捞物种的生态和渔民的行为往往是密不可分的。因此，了解物种生态和渔民行为对有效的渔业管理至关重要。在欧洲，Rajidae是商业捕捞的物种，容易受到过度捕捞，历史上曾在登陆数据中分组，据报道，一些物种的数量下降到了局部灭绝的程度。因此，对这些鱼种的管理很重要，但缺乏对鱼种生态及其与渔业相互作用方式的了解。在这里，我们调查如何不同的生态四个物种的影响与渔业的相互作用，考虑齿轮类型，海洋保护区，捕获和地理位移的位置。我们的研究结果表明，这四个物种与渔业的相互作用不同，例如Rajaclavata更常见的静态网捕获（69%的再捕获）和Raja brachyuramore通常由拖网渔船（77%）。这四个鱼种的捕获地点、深度和位移有明显的差异，导致与海洋保护区形式的现有管理的相互作用不同。例如53%的R。clavatarecaptures的范围内的MPA相比，18%的R。短尾亚目这些结果提供了重要的物种之间的差异，一般分组目前的管理，强调需要进一步的物种具体的研究，以确保有效的管理。
Often the ecology of a commercially fished species and the behaviour of the fishers are inextricably linked. An understanding of both species ecology and fisher behaviour are therefore fundamental for effective fisheries management. In Europe, Rajidae are commercially fished species that are vulnerable to overfishing, have historically been grouped in landings data and declines have been reported to the point of local extinction in some species. Management of these species is therefore important, however an understanding of species ecology and the way they interact with the fishery is lacking. Here we investigate how the differing ecology of four species affects interactions with the fishery by considering gear types, Marine Protected Areas, location of capture and geographic displacements. Our results demonstrate that the four species interacted differently with the fishery, for exampleRajaclavatawere more commonly captured by static nets (69 % of recaptures) andRaja brachyuramore commonly by trawlers (77 %). There were clear differences in the location of capture, depths and displacements of the four species resulting in differing interactions with existing management in the form of Marine Protected Areas. For example 53 % ofR. clavatarecaptures were within the boundaries of an MPA compared to 18 % forR. brachyura. These results provide important differences among species that are generally grouped by current management, emphasising the need for further species specific research to ensure effective management.
