Straying rates and stock structure of British Columbia herring / D.M. Ware … [et al.].: Fs70-1/2000-006E-PDF
The purpose of this paper is to quantify the straying rates of reproductively mature herring that were at large for 1 year before capture. Specifically, for each of the five major herring populations in B.C. the relationship between the distances strayed in 1 year in relation to the distances between these populations was examined. Also, the inter-annual variability in the straying rates for each population was determined, as well as one factor that appeared to modify it. Finally, the measured stray rates are used to show that the amount of biomass moving from one population to another is significant, and affects the natural mortality rate estimated by stock assessment models.
