Status of Atlantic salmon (Salmo salar L.) in Campbellton River, Notre Dame Bay (SFA4), Newfoundland in 1999.

By P.R. Downton, D.G. Reddin, and R. Johnson

Abstract

The status of Atlantic salmon in Campbellton River in 1999 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. The assessment was conducted in response to major management changes that were introduced in 1992 and continued into 1999. Stock status is defined in comparison of the actual egg deposition to conservation requirements. Specifically, there was a moratorium on the commercial Atlantic salmon fishery in insular Newfoundland and restrictions were placed on recreational fishing in each Salmon Fishing Area. In 1999, adult returns were 3,076 small and 493 large salmon compared to the average of 3,061 small and 333 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 for the 1993 and 1994 year class were 0.69% and 0.71% respectively. The percent of the conservation egg requirement achieved for Campbellton River in 1999 was 326%. On average, for the period of 1993-99, Campbellton River achieved 281% of its conservation requirement. However, based on historical runs Campbellton River is only seeing just less than 30% of those past adult salmon migrations.
