Increased aquaculture production has raised concerns about managing protocols to safeguard the welfare of farmed fish, as consumers demand responsible aquaculture practices to provide 'welfare friendly' products. Feeding is one of the largest production cost in a fish farm and can be one of the biggest stressors for fish. Under farming conditions, fish are challenged with artificial diets and feeding regimes, and inadequate feeding conditions cause stress, alteration of normal behavioural patterns, poor performance and eventually diseases and death, which are by no means acceptable neither economically nor ethically. This review aims to highlight the impact of feeding rhythms and feeding time upon physiological and behavioural welfare indicators, which show circadian rhythms as well. Therefore, all these variables should be considered when designing feeding strategies in farming conditions and assessing the welfare state of cultured fish.
水产养殖产量的增加引起了人们对管理方案的关注，以保障养殖鱼类的福利，因为消费者要求负责任的水产养殖实践，以提供“对福利友好”的产品。在鱼类养殖中，饲料是最大的生产成本之一，也是鱼类最大的应激源之一。在养殖条件下，鱼类面临着人工饲料和饲养制度的挑战，而饲料条件不足会导致应激、正常行为模式改变、表现不佳，最终导致疾病和死亡，这在经济和道德上都是不可接受的。本综述旨在强调摄食节律和摄食时间对生理和行为福利指标的影响，这些指标也显示出昼夜节律。因此，在设计养殖条件下的饲养策略和评估养殖鱼类的福利状况时，应该考虑所有这些变量。
