  • Tsolum River Limiting Factors to Pink Salmon Production
    Tsolum River Limiting Factors to Pink Salmon Production Tsolum River Restoration Society K. Campbell 2010 Abstract Pink salmon ( Oncorhynchus gorbuscha) production in the Tsolum River has declined from a high of 100,000 pink salmon adults returning per year in 1935 and 1936 to a record low of ten pink salmon returning to the river in 1984. Copper leaching from the mine site was identified as a threat to all salmon species in the river in 1986, however historical escapement data shows that pink salmon stocks declined sharply in 1957; ten years before the opening of the Mount Washington copper mine. Stocks continued to decline after the mine was closed and despite hatchery enhancement efforts there has been only a limited recovery of odd year pink salmon stocks, and no recovery of even year stocks. The Tsolum River Restoration Society (TRRS) has been successful in seeking funding for projects to reduce copper leaching from the mine site. These efforts include directing flow from the Mt. Washington mine site through the Spectacle Lake wetland in 2003 and the covering of the mine site with a geotextile membrane in 2009. Restoring productivity of pink salmon in the Tsolum River will require the reduction of copper levels from the Mount Washington Mine as well as habitat restoration, changes to hatchery enhancement strategies, and development of estuary habitat. The goal of this report is to identify the limiting factors that must be addressed to restore pink salmon productivity in the Tsolum River after the copper concentrations in the river are reduced to levels that are no longer threaten salmon survival.

  • Investigation of Restoration and Protection Options for Juvenile Salmonids in the Courtenay Estuary
    Investigation of Restoration and Protection Options for Juvenile Salmonids in the Courtenay Estuary March, 2011 Prepared for: Comox Valley Project Watershed Society PO Box 3007, Courtenay B.C. V9N 5N3 Prepared by: Lora Tryon, R.P.Bio Lake Trail Environmental Consulting1 With financial support of: BC Fish and Wildlife Compensation Program (BCFWCP Project # 10.PUN.08) 1 EXECUTIVE SUMMARY The Comox Valley Project Watershed Society is a non-profit group working in the Comox Valley to promote “community stewardship of Comox Valley watersheds through information, education and action” since 1993 (Project Watershed, n.d.). In their efforts to achieve this mission, they have identified the Courtenay River estuary as a critical area of interest, partly due to its importance in sustaining healthy salmon runs. The Courtenay River estuary has experienced past and ongoing impacts from human population growth and development and there was a need to understand how these impacts affect salmon in the estuary. The goal of this study was to provide a foundation for future activities that will help to restore and protect important habitats in the estuary for salmon, including the food webs of which they are a part and the processes that support them. In consideration of the highly complex nature of the Courtenay River estuary, reaching this goal required an ecosystem management approach. Key aspects to ensuring the success of this project were to include ecological principles into the methodology; to identify critical ecological processes that supported healthy salmon populations in the estuary; to include the knowledge and expertise of stakeholders; and finally, to ensure that the results could be interpreted and applied, and were adaptable as new information arose.

    DNA analysis of Puntledge River Summer Chinook - assessment of run timing inheritance and BKD (bacterial kidney disease) resistance Year 1 FWCP Project No. 14.PUN.01 Prepared for: Fish and Wildlife Compensation Program Prepared by: R. Withler 1 and E. Guimond 2 Prepared with financial support of: Fish and Wildlife Compensation Program on behalf of its program partners BC Hydro, the Province of BC, Fisheries and Oceans Canada, First Nations and public stakeholders. March 2015 1 Fisheries and Oceans Canada 2 473 Leighton Ave. Pacific Biological Station Courtenay, BC Molecular Genetics Section V9N 2Z5 Nanaimo, B.C. V9T 6N7 Puntledge River Summer Chinook DNA Analysis 14.PUN.01 EXECUTIVE SUMMARY Genetic analysis methods will be used in this multi-year study to identify individual Puntledge River summer-run Chinook salmon back to parental crosses (both those that were performed in the hatchery and those that occurred in the wild) to study the effects of parental Chinook return migration time and BKD status on their progeny. The genetic analysis is known as ‘parentage-based tagging’ and it allows identification of an individual offspring (at any age, including adults) to its parental pair, as long as both parents have been sampled and genotyped. The genotyping of parents and offspring will be conducted with a set of fifteen microsatellite loci (genetic markers) that are analyzed in the Molecular Genetics lab (MGL) at the Pacific Biological Station. Fisheries and Oceans Canada (DFO) considers the Puntledge River summer-run Chinook salmon a population of high conservation concern. This research will provide information on the most effective strategies to implement in re-establishing successful reproduction both in the hatchery and in the wild.
