The onshore migration of the Atlantic salmon in the Gulf of St. Lawrence in 1937 and 1938, as determined by the tagging experiments of the Quebec Salmon Commission, is described. The salmon that were tagged at Cabot Strait were distributed to all parts of the Gulf of St. Lawrence except the eastern part of the north shore and the northern part of the west coast of Newfoundland. The salmon that were tagged at the eastern end of Belle Isle Strait were recaptured in the sections unoccupied by the Cabot Strait salmon. The separate regions of distribution, the difference in the time of run and the diverse characteristics of the two groups of salmon furnish convincing evidence that there are two distinct stocks of salmon entering the Gulf of St. Lawrence, one northerly through Belle Isle Strait and the other southerly through Cabot Strait. The extent of the distribution of the salmon from the tagging stations within the Gulf of St. Lawrence depends upon the location of the particular station. If the station is situated near the final river destination of the salmon, the distribution is local; and if the station is at some distance, coastal movements of various amplitudes are observed.
