Sea Movements of Canadian Atlantic Salmon Kelts
Salmon related to various rivers of eastern Canada were tagged and liberated after spawning, by the Department of Fisheries in various years from 1913 to 1936. Analysis of the recaptures shows varied movements, the differences from river to river and for the one river from year to year being seen as...
