Abstract

Fishing has many types of impacts on the marine environment. Degradation of seafloor habitats by trawling has been widely studied, along with bycatch mortality, and ghost fishing by traps. Traps or pots are commonly used for catching crustaceans and other organisms, but little research has been conducted on the environmental impacts of trap fishing. Trap fishing causes direct impacts on benthic habitats during setting and retrieval, including dragging along the seafloor, which can lead to the damage and destruction of habitat components such as corals, sponges, and other epifauna. Lines connecting multiple traps increase the overall footprint and cause additional damage. Lost traps and debris can cause damage to coral, submerged aquatic vegetation, and epifauna, especially if moved by storms. Although the trap footprint is small, movement of the trap can expand the impact footprint by an order of magnitude. Trap lines cause whale entanglement and death, and there is much interest in reducing the number of vertical lines as well as their potential for entanglement. New technologies for deploying, locating, and recovering traps are now being developed. The future of trap fisheries will require research on new ways to reduce their negative impacts on benthic and pelagic resources.

陷阱的起起落落：环境影响、纠缠、缓解以及捕捞甲壳类动物和鱼类的未来

摘要

捕鱼对海洋环境有多种影响。拖网捕捞造成的海底栖息地退化、兼捕死亡率和陷阱造成的幽灵捕鱼已得到广泛研究。陷阱或罐子通常用于捕捉甲壳类动物和其他生物，但关于陷阱捕鱼对环境的影响的研究很少。陷阱捕捞在设置和回收过程中对底栖栖息地造成直接影响，包括沿海底拖曳，这可能导致珊瑚、海绵和其他底栖动物等栖息地组成部分的破坏和破坏。连接多个陷阱的线路会增加整体占地面积并造成额外损坏。丢失的陷阱和碎片可能会对珊瑚、淹没的水生植物和底栖动物造成损害，尤其是在被风暴移动的情况下。虽然陷阱足迹很小，陷阱的移动可以将影响足迹扩大一个数量级。诱捕线会导致鲸鱼纠缠和死亡，因此减少垂直线的数量及其纠缠的可能性引起了人们的极大兴趣。现在正在开发用于部署、定位和回收陷阱的新技术。诱捕渔业的未来将需要研究减少其对底栖和中上层资源的负面影响的新方法。
