Following the development of demand-feeding systems, many experiments have been conducted to explore feeding motivation and feed intake in farmed fish. This work aims to review a selection of studies in the field, focusing on three key factors, related to demand feeding and fish welfare. Firstly, we outline how demand feeders should be considered when developing feed management strategies for improving welfare in production conditions. Secondly, via laboratory demand-feeding experiments, we show self-feeding activities depend not only on feeding motivation and social organisation, but also on individual learning capacity and risk-taking behaviour. Thirdly, we report encouraging results demonstrating that when presented with two or more self-feeders containing complementary foods, fish select a diet according to their specific nutritional requirements, suggesting that demand feeders could be used to improve welfare by allowing fish to meet their nutritional needs.
随着需求 feeding 系统的发展，许多实验已经探索了养殖鱼类的摄食动机和摄食量。本工作旨在综述该领域的一些研究，重点关注与需求 feeding 和鱼类福利相关的三个关键因素。首先，我们概述了在制定饲料管理策略以提高生产条件下福利时应如何考虑需求 feeder。其次，通过实验室需求 feeding 实验，我们表明自我 feeding 活动不仅取决于摄食动机和社会组织，还取决于个体的学习能力和冒险行为。第三，我们报告了令人鼓舞的结果，表明当提供两个或更多含有互补食物的自 feeder 时，鱼类会根据其特定的营养需求选择饮食，这表明需求 feeder 可用于通过允许鱼类满足其营养需求来提高福利。
