Abstract. The effects of dietary treatments were investigated as a prophylactic measure to minimize the occurrence and severity of bacterial kidney disease (BKD) infections in Atlantic salmon, Salmo salar L., at Margaree Fish Culture Station, Nova Scotia, Canada. Six diets containing various levels of calcium, magnesium, zinc, iron, copper, manganese, cobalt and iodine in addition to one commercial diet were fed to post–yearling Atlantic salmon in two consecutive experiments. Natural infection was utilized to examine the effects of each diet on the prevalence of BKD. Diet containing high levels of iodine (4.5 mg/kg feed) and fluorine (4.5 mg/kg) reduced BKD prevalence rate to 3% and 5% respectively compared to 95% and 38% with commercial feed. Some other experimental diets also reduced prevalence of BKD, but to a lesser degree than the diet with additional iodine and fluorine.
