Evidence indicating that the western north Atlantic bluefin tuna spawns in the Straits of Florida during May and early June is presented. Such evidence includes the occurrence of ripe and recently spawned adult fish simultaneously with what may be fertilized eggs and larvae. Further evidence includes the occurrence of juveniles and young in the vicinity of the spawning grounds. It is inferred that the large, adult fish spawning in the Straits of Florida are the same which are found in northern waters during summer. The discovery of spawning grounds in the western Atlantic also suggests that the American and European bluefin tuna represent separate, independent units.
