Run timing and migration routes of returning Atlantic salmon in the Northern Baltic Sea: implications for fisheries management
Abstract Return migration of Atlantic salmon, Salmo salar L., was studied in the Gulf of Bothnia, northern Baltic Sea, by a mark‐recapture experiment and catch records from commercial trap‐nets. Coastal salmon fishing is regulated by delayed opening of the fishery in consecutive regions based on the...
