Wow, good debate. There is definitely no perfect answer here, but strictly choosing from the list I would have to go with D. I have lots of other opinions...many of which have already been brought up...
I also thing total yearly bag limit has to be reduced to maybe 10 or so Chinook...at the VERY most. 30 is ridiculous. That, plus some coho (don't forget about sox & chum) is more than enough for anybody. If you are trying to feed a big family, bring some of them with you for the increased limits...not to mention the experience.
It's clear that most on here are mainly chuck fishermen (I am too) but I don't think we could/should ever totally cut out the river guys. I believe there should be selective fisheries on enhanced hatchery rivers where those populations can handle it (stamp, vedder, etc), and leave the wild rivers alone (where necessary) for a full salmon cycle. (6 years in my opinion - except the handful of systems with 7 year fish - Whonnock, Kilbella, etc). We need to put more effort into enhancement to provide more harvesting opportunities...the US seems to do a better job of this than we do.
I don't think shutting down winter spring fishing would have any measurable effect, and I would sooner see people on the water keeping an eye on things, and providing reports...because DFO clearly doesn't have our waters covered well enough, and I often question their studies. I believe they have alot to learn from fishermen...they just need to learn to work with us a little better.
Do you know that IGA is selling Chum fillets from CHINA that are caught in the north pacific? The package calles them "wild pacific salmon". Ours are used for their roe, cat food and fertilizer. Why do I rarely see Canadian chum on the shelf?
I think we need to farm salmon (we farm everything else we eat) but we need to do it much more responsibly - in tanks, etc.
While sporties are definitely part of the problem I believe there are even bigger commercial and FN issues have to be addressed, and Canada and the US have to do a better job of managing our shared resource together...but I don't have time for that can of worms right now.
Cheers, Jay
