While there seem to be few people posting, Spring Velocity, there have been 11,000 views which is interesting. The issue around declining chinook is interesting, as a general statement if one looks at the total chinook harvests over the last 10 years from California to SEAK, yes there has certainly been a decline overall. However, looking at Georgia Strait, to say that there is a huge lack of chinook I believe is misleading, and not entirely correct, but it seems to be the main focus of the save the whales groups. There are certain chinook runs which are doing pretty well, notable the South Thompson and lower Fraser chinook. The lower Fraser were at record numbers 3 or 4 years ago, and have declined a little to more average returns, but still healthy numbers. The chinook runs most in trouble are the spring and summer runs, as well as the yearling chinook which enter the sea as larger 1 or 1 + year olds. The single most successful stock, the South Thompson enter the ocean as small smolts in July into late July. We have been told by the scientists they know that seals and sea lions are eating emerging smolts, and of course they are targeting the larger smolts....yearlings for sure.
For the last three years the Lower Fraser chinook have returned through Georgia Strait, and from April through to August have been in large schools from Qualicum over to Texada Island, down to Nanaimo, Porlier Pass, and over to mainland providing excellent to outstanding fishing...reading the fishing reports from that time period for the Vancouver thread and Nanaimo thread will reinforce that....as would anyone who gets out on the water and fishes in these areas.
I still maintain that the availability of chinook is not the main problem during the April to August period if they were to forage in this large area. I believe that not is like many issues...a series of interconnected negative impacts....of course the genetics play a major role, I believe, and the build of a huge load of toxins does, I still maintain impact feeding desire and energetics of these animals. Yes, from late October to April; there is certainly a lower number of chinook, particularly in the 20 lb. range, although I understand the Birkenhead run comes through Georgia strait in February / March, and are larger fish, in the 20 lb. range.
Spring Velocity was right to look for solutions based discourse, and I think that should use the latest available knowledge to use better hatchery techniques, examine which specific stocks to choose for enhancement, and look at predation by pinnipeds as a beginning strategy.
