Impact of high water carbon dioxide levels on Atlantic salmon smolts ( Salmo salar L.): Effects on fish performance, vertebrae composition and structure
The role of high carbon dioxide (CO 2 ) levels on fish performance, bone structure/composition and as a potential cause of spinal deformities was studied. Two groups of fish were exposed to a low (control) and a high level of CO, for 135 days during the freshwater period. After smoltification, the f...
