Seaward migrating Atlantic salmon smolts with low levels of gill Na+, K+ -ATPase activity : is sea entry delayed?
Two groups of migrating wild Atlantic salmon (Salmo salar) smolts caught within a 1 week interval in the River Alta, northern Norway, were tagged with acoustic transmitters and measured for gill Na+, K+ -ATPase activity in order to compare their smolt status with timing of sea entry. The first group...
