An evaluation of the natural mortality rate used in the assessment of British Columbia herring stocks / J. Schweigert and R. Tanasichuk.: Fs70-1/1999-22E-PDF
The objectives of this study were to investigate the estimates of natural mortality used in recent Pacific herring assessments with a view to evaluating the impact of variation in this parameter on perceptions of the abundance and trends in stock abundance. The sensitivity of abundance estimates to variation in natural mortality also provides some insight into the significance of failures to meet some of the other assumptions about the natural mortality rate on abundance levels.
