Stock composition of northumberland strait, nova scotia atlantic salmon (salmo salar) commercial fisheries by Canada( Book )

One of the major challenges facing the management of Atlantic salmon is estimating the stock mixture of commercial fisheries. This report presents the results of scale samples from Atlantic salmon caught in 1983 in the Northumberland Strait, Nova Scotia commercial fisheries, as well as salmon returning to Miramichi, New Brunswick and 4 Northumberland Stait, Nova Scotia rivers. Circuli count and distance measurements in freshwater, first sea summer and first sea winter zones were used to differentiate stock origin of the commercial catch. Only virgin 2SW salmon were analyzed, as they comprised most of the commercial catch
