Nanaimo News Bulletin: Inquiry into sockeye collapse more relevant in light of 2010 record run.

David Welch, Kintama’s President & CEO, was interviewed for a Nanaimo, BC newspaper article, voicing his concerns over Pacific salmon management and emphasizing the major difference between this year’s record-breaking sockeye run and last year’s poor returns.

Analysis submitted to Cohen Commission

David Welch submitted a document to the Cohen Commission containing an analysis of where the 2009 Fraser River sockeye run failure likely occurred.  The submission is titled: “Location & Timing Of Poor Marine Survival Causing The 2009 Fraser Sockeye Failure: Elevated Smolt Mortality After Migration Through Discovery Passage & Queen Charlotte Strait.”  The Commission is a federally appointed inquiry into the decline of Fraser River sockeye.

2009 report submitted to Bonneville Power Administration (BPA)

The Columbia River study, continued now for four years, shows no significant difference in survival between Chinook smolts travelling through either 4 or 8 Columbia River dams.  The addition of an early release group of barged smolts in 2009 indicated no difference in survival despite the length of time between the first and last release groups (approximately 1 month), but some behavioral variations were observed.

2006-2009 Multi-year Summary Report for Bonneville Power Administration

The findings of the BPA project from 2006 to 2009 have been compared and summarized.  Highlights include: 

  1. Repeatedly over the entire study, no difference in delayed mortality was found between hatchery-origin spring Chinook from the Snake River (8 dams to transit) and the Yakima River (4 dams).
  2. Barged and freely migrating Chinook revealed no evidence of differential-delayed mortality; this does not support the hypothesis that stress from transportation results in a reduction in survival.
  3. Survival rates in freshwater and coastal ocean are equivalent. Read the report here.

Report to BC MoE in – Bulkley Steelhead

Kintama recently delivered the report, “Acoustic Telemetry Measurements of Migration and Movements of Adult Steelhead (Oncorhynchus mykiss) within the Bulkley River, 2009”, to British Columbia’s Ministry of Environment.  The study provides correction numbers for the yearly mark-recapture program in the Moricetown Canyon.  Of note, only 56% to 59% of tagged fish were observed passing the recapture site during active recapture efforts.

Skeena/Bulkley steelhead report submitted to BC MoE

Our 2008 research on the Skeena and Bulkley Rivers has spawned a report for the British Columbia Ministry of Environment: “Acoustic Telemetry Measurements of Survival and Movements of Adult steelhead (Onchorhynchus mykiss) within the Skeena and Bulkley Rivers, 2008.”  Acoustic technology has again proved itself useful, this time in the free-flowing Skeena and Bulkley Rivers, following its application for identifying survival, travel speed and areas of milling for returning adult steelhead.

Salmon River Fishway Assessment Study report in.

The BC Hydro diversion dam on the Salmon River, Vancouver Island, poses a physical barrier to adult salmon migrating up the river.  In 2008, Kintama receivers indicated that less than 7% of adult coho might travel up through the fishway near the dam.
