Research vessel drift-netting in the Irminger Sea during the summers of 1966 and 1973-75 yielded 80 salmon, of which 77 were one-sea winter fish, 2 were two-sea-winter fish , and 1 was a previous spawner. The proportions of salmon of North American and European origin caught in 1973-75, estimated by discriminant functions based on scale characters, were 21 and 79% respectively. The average smolt age of North American salmon (3.4 yr) was significantly higher than that of European salmon (1.9 yr), but the average length of the former (62.9 cm) was lower than that of the latter (67.8 cm). The recapture at East Greenland of adult salmon tagged as smolts in North American and European rivers also indicates a mixed population in the area. The size of the feeding population could not be estimated from the available data, but catch-per-unit-effort data indicate that it is probably much smaller than in West Greenland waters.
