Fish welfare at harvest is easily compromised by poor choice of handling and slaughter methods, lack of attention to detail and by unnecessary adherence to fish farming traditions. The harvest process comprises fasting the fish to empty the gut, crowding the fish, gathering and moving the fish using brails, fish pumps, and sometimes also road or boat transport and finally stunning and killing the fish. The harvesting processes commonly used for bass, bream, carp, catfish, cod, eel, halibut, pangasius, salmon, tilapia, trout, tuna and turbot are outlined. These harvesting processes are discussed; the consequences for fish welfare identified and practical tests which can be made at the harvest site highlighted. Welfare at harvest for the majority of farmed fish species can be improved by adopting and adapting existing procedures already known to be beneficial for fish welfare through their use in other fish farming systems or with other species. It is seldom necessary to develop completely new concepts or methods.
鱼类在收获时的福利很容易受到处理和屠宰方法选择不当、缺乏细节关注以及对水产养殖传统的不必要坚持的影响。收获过程包括让鱼禁食排空肠道，将鱼群集，使用绳索、鱼泵收集和移动鱼，有时还需要进行道路或船只运输，最后对鱼进行致昏和宰杀。本文概述了鲈鱼、鲤鱼、鲫鱼、鲶鱼、鳕鱼、鳗鱼、大比目鱼、 Pangasius 鱼、三文鱼、罗非鱼、鳟鱼、金枪鱼和大菱鲆等鱼类常用的捕捞方法。讨论了这些捕捞方法，确定了对鱼类福利的影响，并强调了在收获现场可以进行的实际测试。通过采用和调整已经在其他水产养殖系统或其他物种中使用的、已知对鱼类福利有益的现有程序，大多数养殖鱼类的收获福利都可以得到改善。很少有必要开发全新的概念或方法。
