Dolphin interactions with coastal fisheries are of major concern, reportedly leading to gear damage, which increases the cost of coastal fishing globally and in the Mediterranean Sea. The aim of this study was to determine the effect that gear, target species, mesh size, depth, soaking duration, fishing area, and season have on net depredation frequency and to offer insights on possible mitigation solutions. From November 2013 to February 2016 we monitored 107 active coastal fishers in 22 ports of the northern Aegean Sea coastline, identified the main target species of the fishery and recorded the damages on gill nets and trammel nets caused by dolphins, mainly the common bottlenose dolphin (Tursiops truncatus). Quasi‐binomial generalized linear models were used to determine the relationship between the examined factors and depredation frequency. The analysis revealed that the gears mostly depredated were gill nets and trammel nets with small mesh sizes, mainly targeting surmullet (Mullus surmuletus), red mullet (Mullus barbatus), common sole (Solea solea), European hake (Merluccius merluccius), and caramote prawn (Melicertus kerathurus). The probability of depredation was also significantly dependent on the fishing area.

影响爱琴海北部沿海渔业中海豚捕食的因素：对确定缓解措施的意义

海豚与沿海渔业的相互作用是主要问题，据报道导致渔具损坏，这增加了全球和地中海沿岸捕捞的成本。这项研究的目的是确定渔具，目标物种，网眼大小，深度，浸泡时间，捕鱼面积和季节对净折旧率的影响，并提供有关可能的缓解措施的见识。从2013年11月到2016年2月，我们在爱琴海北部海岸线的22个港口监视了107位活跃的沿海渔民，确定了该渔场的主要目标物种，并记录了海豚对，网和and虫网的破坏，主要是常见的宽吻海豚（run藜）。使用准二项式广义线性模型确定检查因素与折旧频率之间的关系。分析表明，大多数不赞成使用的渔具是网眼尺寸较小的刺网和tram虫网，主要针对苏mul（Mullus surmuletus），红鱼（Mullus barbatus），普通（Solea solea），欧洲无须鳕（Merluccius merluccius）和水獭大虾（Melicertus kerathurus）。掠夺的可能性也明显取决于捕鱼区。
