Actually you are mistaken.
The post immediately above mine makes that analogy very directly.
As far as a solution, there is no short and catchy answer to this. Government policy decisions are never completely driven by science, because they need to get reelected and people don't generally vote according to science, and pacific salmon is a regional issue that can get sacrificed to bigger political ambitions, and both whales and salmon are large attractive animals to people who might vote liberal across the country, and don't have a in depth understanding of the issue (and don't care beyond the surface reaction). It is also the case that the science on this is fairly inconclusive, and it is reasonable to employ the precautionary principle when making a decision where the cost of getting it wrong is very high.
There is now a considerable history of fisheries being managed into the ground in Canada and around the world. I think its pretty likely that freshwater habitat and ocean conditions as well as any intensive commercial harvest have much more impact than sport fishing. I also think most sport fishers have less impact on whales than other types of marine traffic. Last year the whales we saw feeding were mostly humpbacks and they seemed totally oblivious to sport fishers which as far as I saw made an effort not to bother them.
I don't know myself if the SRKW closed areas will make a difference for the whales, I honestly don't have the expertise. I tend to think the closures are unnecessary and of course I don't like anything which limits my fishing.
I however really don't think it is in the political interests of sports fishers to take on the image of the antivax trucker protest.I
