Frankly, I'm OK with the 6 hali limit, but I'm sure not OK with the size limit as I have absolutely no idea how I would deal with measuring and releasing a +60 lb hali at the side of my boat. That part of the new regs are going to create some very dangerous conditions on the water and have not been particularly well thought out- no doubt conceived, as the letter writer suggested by a DFO person who has never actually dealt with a halibut that has swallowed a barbed hook.
I consider myself fortunate that in the few years since I've retired and have taken up boating and sports fishing on a somewhat regular basis, that I have not had to deal with this problem. I haven't caught any halibut over 40 lbs and I'll be quite happy if that pattern continues - as would, I suspect, most lay fishermen.
