In intensive Atlantic salmon smolt rearing systems, oxygen supplementation of the water is required, but the importance of tight regulation of oxygen supply may not always be recognised. Consequently, there is a risk that fish may be exposed to water which is supersaturated with oxygen. This study was done to investigate the time course and exposure level associated with hyperoxia-induced gas bubble disease, through a combination of morphological and behavioural methods.Atlantic salmon pre-smolts were divided into three groups; one control group (no added oxygen), and two groups receiving gradually increasing oxygen saturations over three weeks, the high oxygen exposure group...</br>
