Abstract
The influence of formalin and malachite green on ventilation rate, cough rate and oxygen consumption rate of rainbow trout, Salmo gairdneri Richardson, was investigated. The effect of suspended silt on these parameters is also described. In all cases ventilation rate increased by up to 60%. Cough rate increased more dramatically by up to 300%. Some acclimation to the various treatments was observed. Rates of oxygen consumption increased markedly in all cases but particularly when the fish were exposed to silt, when an increase of 500 to 700% was noted. These data emphasize the need for stress-free husbandry when using prophylactics or disease treatments and demonstrate the high oxygen demand of fish in these conditions.
