Estimation of the Labrador component of prefishery abundance of North America Atlantic salmon (Salmo salar L.) in 1998 / by D.G. Reddin. : Fs70-1/1999-91E-PDF

Because of a lack of information on which to directly base returns to Labrador rivers, estimates of returns prior to the commercial fishery were developed using commercial catches in the Labrador fishery corrected for exploitation, origin and sea age class. Returns to freshwater were estimated by subtracting commercial catches and spawners estimated by subtracting angling catches. In 1998, the Labrador commercial fishery was closed effectively ending this time series. The purpose of this paper is to examine alternate methods for determining prefishery abundance of North American maturing and non-maturing salmon to include Labrador return and spawner estimates for 1998.
