Status of Atlantic salmon (Salmo salar L.) in Campbellton River, Notre Dame Bay (SFA 4), Newfoundland in 1998 / by P.R. Downton and D.G. Reddin. : Fs70-1/1999-83E-PDF
The status of Atlantic salmon in Campbellton River in 1998 was determined from the number of salmon counted through a portable fish counting weir (fence) located on the main stem just above head of the tide as well as from biological data collected from the recreational fishery. In 1998, adult returns were 3,275 small and 402 large salmon compared to the average of 3,059 small and 306 large salmon, 1993-98. Historical records indicate that circa 1800, about 12,000 adult salmon were captured at a harvesting weir. The freshwater survival from eggs to smolt from the 1993 year class was 0.68%. The percentage of the conservation egg requirement achieved for the Campbellton River in 1998 was 317%. On average, for the period 1993-98, Campbellton River achieved 275% of its conservation requirement.
