Swimming exercise (bodylenghts/sec), and dissolved oxygen (DO), are important environmental variables in aquaculture. While there is an obvious physiological association between these two parameters, their interaction has not been adequately studied in Atlantic salmon, Salmo salar and Rainbow trout, Oncorhynchus mykiss. Since both variables can be easily manipulated in modern aquaculture systems, we sought to assess the impact of these parameters, alone and in combination, on the performance, health, and welfare parameters of the two species. Atlantic salmon and Rainbow trout were stocked into twelve circular 0.5 m3 tanks and exposed to either high (1.5-2 BL/s) or low (
