An understanding of behaviour is used in zoos, laboratories and agriculture to reduce stressful aspects of the captive environment for animals. While fish are one of the most cultivated of all vertebrate groups, incorporating their behaviour into production management has proved elusive. Here, we evaluate the current evidence base relating to use of (i) innate behaviours of fish and (ii) their ability to learn new behaviours via human‐mediated training or through social learning, in fish farms. Studies that tested habituation and conditioning (training) as a tool to improve welfare demonstrate positive effects for improving fish welfare and coping capacity. However, methods solely reliant on innate behavioural responses to stimuli will always be imperfect, due to variation in individual responses which are often context dependent. To date, there has been no successful demonstration of social learning as a tool for aquaculture. While many experimental scale studies report promising results, few have translated to commercial scale, highlighting a mismatch between theoretical and practical use and cautions against extrapolation of results from small‐scale studies to commercial situations. While some promising evidence exists that fish behaviour can be integrated into farm management, logistical and scale‐related hurdles must be overcome before this can occur. We conclude that fish behaviour is an additional and currently under‐researched resource that could be integrated into farm practices to improve production and welfare in industrial aquaculture.

采取鱼类行为以提高工业水产养殖产量和福利的挑战和利益

在动物园,实验室和农业中使用对行为的理解,以减少圈养动物的压力。尽管鱼类是所有脊椎动物中最受养殖的鱼类之一,但将其行为纳入生产管理已被证明是可望而不可及的。在这里,我们评估了当前在鱼类养殖场中与使用(i)鱼的固有行为和(ii)通过人类介导的培训或通过社会学习学习新行为的能力有关的证据基础。检验习惯性和适应性(训练)作为改善福利的工具的研究表明,改善鱼类福利和应对能力具有积极作用。然而,由于个体响应的变化通常取决于上下文,因此仅依赖于对刺激的固有行为响应的方法将始终是不完善的。迄今为止,没有成功地证明社会学习是水产养殖的一种工具。尽管许多实验规模的研究报告了令人鼓舞的结果,但很少有成果转化为商业规模,这凸显了理论和实际用途之间的不匹配,并提醒人们不要将结果从小规模研究推算到商业环境中。尽管有一些有前途的证据表明鱼类行为可以纳入农场管理中,但在此之前必须克服与物流和规模有关的障碍。我们得出的结论是,鱼类行为是一种额外的且目前尚未得到充分研究的资源,可以将其整合到农场实践中以改善工业水产养殖的生产和福利。尽管许多实验规模的研究报告了令人鼓舞的结果,但很少有成果转化为商业规模,这凸显了理论和实际用途之间的不匹配,并提醒人们不要将结果从小规模研究推广到商业环境。尽管有一些有前途的证据表明鱼类行为可以纳入农场管理中,但在此之前必须克服与物流和规模有关的障碍。我们得出的结论是,鱼类行为是一种额外的且目前尚未得到充分研究的资源,可以将其整合到农场实践中以改善工业水产养殖的生产和福利。尽管许多实验规模的研究报告了令人鼓舞的结果,但很少有成果转化为商业规模,这凸显了理论和实际用途之间的不匹配,并提醒人们不要将结果从小规模研究推算到商业环境中。尽管有一些有前途的证据表明鱼类行为可以纳入农场管理中,但在此之前必须克服与物流和规模有关的障碍。我们得出的结论是,鱼类行为是一种额外的且目前尚未得到充分研究的资源,可以将其整合到农场实践中以改善工业水产养殖的生产和福利。尽管有一些有前途的证据表明鱼类行为可以纳入农场管理中,但在此之前必须克服与物流和规模有关的障碍。我们得出的结论是,鱼类行为是一种额外的且目前尚未得到充分研究的资源,可以将其整合到农场实践中以改善工业水产养殖的生产和福利。尽管有一些有前途的证据表明鱼类行为可以纳入农场管理中,但在此之前必须克服与物流和规模有关的障碍。我们得出的结论是,鱼类行为是一种额外的且目前尚未得到充分研究的资源,可以将其整合到农场实践中以改善工业水产养殖的生产和福利。
