If one needs to try and make an economic justification to go out fishing, then you’re going to have a bad time. For the majority of people, cost of gas/gear/time >> just buying them from the fish market.
Being able to keep something for the BBQ is a nice perk, no argument here, but if that’s how someone measures success, then they’re probably going to come out on the short end of that calculation.
As for the OP question, it would be interesting to see how much crowding would be reduced if the limit was raised to 4. Some people would leave right away. Some would release all sockeye after 3 in hopes of a spring. Some would continue to fish and release everything after 4 simply because they’re having a fun time of it out there, and that would be perfectly legal.
And isn't it plausible that raising the limit could actually motivate a lot more people to make the trip out who wouldn't otherwise go and as a result would be just as crowded or maybe even worse anyways?
Good points.
Given the popularity of this fishery, the number of people that are on the fence about going or not going based on whether the limits are two or four may not be that great. I also have my doubts about whether raising the limits will actually significantly reduce the number of trips. This fishery was much anticipated months ago and many have booked off vacation time. They will go regardless.
If they do go to a 4 fish limit, they will need to make some modifications to the rules that are currently in place:
-all fish hooked in the mouth area must be retained (no C&R).
-must stop fishing after the 4th fish is retained (same as the steelie rule)
-cannot retain any Chinook salmon over 50 cm. unless caught using a bar rig setup (can easily be defined in the regs)
-these rules apply to the fraser sockeye fishery only and not to any other river systems.
Those rules will hopefully help with the crowding and more importantly the number of fish hooked and release whom in my opinion have a very small chance of survival.
