Physiological effects of freshwater bathing of Atlantic salmon ( Salmo salar ) as a treatment for amoebic gill disease
The physiological effects of bathing marine net-pen reared Atlantic salmon with freshwater: the treatment for amoebic gill disease (AGD) in Tasmania was evaluated. Acute exposure of AGD affected salmon to hyperoxic freshwater for at least 2 h resulted in a decrease in gill succinic dehydrogenase act...
