Return migration of Atlantic salmon in the River Tana: the role of environmental factors
Multi‐sea‐winter Atlantic salmon (75–115 cm fork length L F , 2–4‐winter fish) were radio‐tagged in the Tanafjord (700 N), Norway, in 1992–1993, and 130 fish entered the large subarctic River Tana (Teno). They entered the fresh water at any time of the tidal cycle but more so during the high and ebb...
