The F 1 progeny of irradiated and unirradiated coho sahnon were the object of a study on the occurrence of gross physical anomalies. Experimental lots consisted of 69,000 F 1 progeny of coho salmon that had been irradiated during the egg‐and‐yolk‐absorption stage with a 0.1 curie cobalt‐60 source at a daily dose of 0.44 roentgens, resulting in a total dose of 40 roentgens. Control lots consisted of 95,500 F 1 progeny of unirradiated coho salmon. Anomalies that occurred most commonly in both experimental and control lots were those concerning the operculum, the spinal column, the tail, and the fins. No significant differences were found between experimental and control lots in regard to the occurrence of gross physical anomalies.
