按照目前的做法，食用鱼养殖可能会引起对养殖鱼类福利的关注，这是一个受到相当关注的问题。作为脊椎动物，鱼类与更常养殖的鸟类和哺乳动物有许多共同的特征，因此从考虑这些群体中得出的许多福利原则也可以适用于鱼类。然而，鱼类有着漫长而独立的进化历史，也适应了一个非常不同的水生环境。由于这些原因，他们有一些特殊的功能，是相关的福利是如何定义，评估和促进，这些都进行了讨论。被认为是各种方法，可供研究人员识别和评估鱼类的好和坏的福利，包括身体健康和生理，行为和基因组状态的评估。还审查了可用于工作农场的实用福利指标子集。本文概述了可能损害鱼类福利的集约化水产养殖的各个方面，以及可用于减轻这种不利影响的一些战略。最后，本文结束时简要展望未来，确定可能的变化，水产养殖的做法，以及这些可能会影响养殖鱼类的福利。
As currently practised, the culture of fish for food potentially raises concerns about the welfare of farmed fish, and this is a topic that has received considerable attention. As vertebrates, fish share a number of features with the birds and mammals that are more commonly farmed, so many welfare principles derived from consideration of these groups may also be applied to fish. However, fish have a long, separate evolutionary history and are also adapted to a very different, aquatic environment. For these reasons, they have a number of special features that are relevant to how welfare is defined, assessed and promoted and these are discussed. The various methods that are available to researchers for identifying and assessing good and bad welfare in fish are considered, including assessment of physical health and physiological, behavioural and genomic status. The subset of practical welfare indicators that can be used on working farms is also reviewed. Various aspects of intensive aquaculture that can potentially compromise fish welfare are outlined, as are some strategies available for mitigating such adverse effects. Finally, the paper ends by looking briefly to the future, identifying likely changes in aquaculture practices and how these might affect the welfare of farmed fish.
