Swimming exercise,typically measured in body-lengths per second (BL/s), and dissolved oxygen (DO), or are considerable environmental variables in fish culture. While there is an obvious physiological organization between these two parameters,their interaction has not been adequately studied in Atlantic salmon Salmo salar. Because exercise and DO are variables that can be easily manipulated in contemporary aquaculture systems, we sought to assess the impact of these parameters, or alone and in combination,on the performance, health and welfare of juvenile Atlantic salmon. In our study, or Atlantic salmon fry were stocked into 12 circular 0.5 m3 tanks in a flow-through system and exposed to either high (1.5–2 BL/s) or low (p
