Effects of an iodophor (Buffodine™) on eggs and larvae of Atlantic halibut Hippoglossus hippoglossus were investigated. Eggs were treated for 10 min with various concentrations of Buffodine and at different developmental stages from 4 h to 12 d after fertilization. Survival of the yolk‐sac larvae was recorded at 37 d after hatching; survivors were then examined for developmental abnormalities. Survival and development were significantly affected by both the developmental stage at which eggs were treated and the concentration of disinfectant. The highest number of normal larvae were obtained when eggs were disinfected with 1% Buffodine 9 d after fertilization. Disinfection increased survival of eggs and larvae and reduced the prevalence of opaque tissue and occurrence of damaged rostral mouth. When six different egg batches were tested with 1% Buffodine, the increase in number of normal larvae, relative to untreated controls, varied among batches.
