"The abundance estimates for different salmon species are affected by different sources of potential bias and uncertainty. We conducted a comprehensive review of the Nass salmon capture-recapture estimation programs and annual abundance estimates. This review examines assessment and estimation procedures including a comprehensive review of key input data sources and analysis methods used to estimate abundance for each species. We identify key assumptions and sources of bias in the current program; explore the sensitivity of mark-recapture estimates to these assumptions; and identify new sources of relevant information from species-specific research projects"--Abstract, page xi.
