Exploitation rates in different sea fisheries were estimated by tag returns of Atlantic salmon released as hatchery-reared smolts in the River Drammenselv, SE Norway, 1984-1986. The salmon were exploited in distant fisheries at the Faroes and Greenland, in marine fisheries in Norwegian home waters and in the River Drammenselv. The exploitation rate of these fish was low at Greenland, moderate at the Faroes and relatively high in Norwegian home waters. However, the exploitation rate in home waters was lower than for other Norwegian salmon stocks. Exploitation within the River Drammenselv was estimated by combining catch statistics, counts of ascending fish in a salmon ladder and mark-recapture experiments downstream from the ladder. From 1985 to 1988, the rod exploitation rates varied between 0.33 and 0.53.
