Look for opportunities for overall improvement, but leave details for others more knowledgeable. Bob PSEF - $30 million program in late 1990s from federal. Work managed by PSF, $ managed by – Vancouver foundation. Focused on developing recovery plans on number of watersheds (Shuswap/Salmon R, River Inlet, Coldwater, Englishman, Nimpkish, Cowichan later under different funding and same methodology). Program eventually folded into PSF funding framework. Lots of work on habitat, some on harvest. Probably all still relevant information. Not much has changed since then. David suggest pairing Chilliwack and Harrison, thus representing almost all Fraser lates. – Dave run them separately, or together as single. – Gayle/Chuck run them separately – Dave what CWT represents Clayoquot? – Roberston, ocean mortality adjusted at Area 23 (?). take info from CWT to characterize Chuck/Wilf – Clayoquot as wild stock. Dave so this would be another paired stock set? (Yes) – [discussion of hatchery/wild contributions to each of the pilot stocks] [description of homework, to think of sensitivities] Dave – Jeff to test out examples of this ideas like increasing harvest by X% and by Y%, or increasing – – production by 200% or decreasing by 50%, or assuming increasing in productivity from habitat of 10% or 20%. Then I say, I am interested in outputs of escapement vs. benchmarks over time, and catch by fishery and by area, and overall abundance. Is that what we’re looking for. Dave yes, except cannot estimate overall abundance if all fo the populations and stocks aren’t in there. – Jeff need to understand broader impacts on overall catch and abundance want to know if slight – – reduction in Nicola results in large reductions in catch of other stocks (due to mixed stock) [missed] Dave often most useful to look at relative changes between scenarios instead of absolute. May be – dangers with absolute predictions if analyses don’t include all stocks.
