Aquaculture is a growing industry that is increasingly providing a sizable proportion of fishery products for human consumption. Thus, in the last years, several efforts are made in improving fish welfare. As well as in the rest of vertebrates, fish welfare is sensible to a balanced redox status. Numerous inputs like diet and environmental factors could alter this balance. In this sense, the last feeding strategies are focused on developing a more sustainable aquaculture, trying to maintain a redox balance. On the other hand, under culture conditions, animals cannot migrate to more favourable conditions, and environmental stress is one of the most relevant inputs that could compromise redox balance. This chapter is focused on the review of last works in redox balance analysis in Mediterranean aquaculture species and is organized as follows: (1) redox reactions on poikilotherms versus homeotherms; (2) effect of feeding strategies and environmental stress in fish redox balance; and (3) wide vision in fish redox balance.
