Right. Exactly my point. We've tried different policies, none seem to work. So you try something different. I'm all for the poison, except (a) that the government won't ante up the funds and (b) they don't have the political stomach.
I have more practical viewpoint on this (sorry, but it is more practical): since no one has cited any evidence that a zero perch retention has done anything, why not try the opposite? Forget the "philosphy" of it rewarding the idiots, isn't the bottom line that we want better trout fisheries? So, short of rotenone, isn't the best way to do that is to reduce perch numbers? Additionally, you could turn off aerators, hope for a complete and total winterkill? I'm saying we've stuck to the principle of "let's not reward the idiots". Great. Awesome. And it's got us a whole lotta nothing except perch infested lakes where (until the regs changed back this year), I wasn't allowed to kill the little buggers. So... do you draw your sword on a hill of principles and rant about it....or do something practical?
We're all frustrated. Again, if anyone has some actual evidence to support the policy of zero retention perch, great. I suspect it is non-existent. So...back to chasing our tails.
Maybe a new gov't will do something... (yeah right). So sure, let's go for the poison. That is the practical solution actually: if Alberta could even come close to replicating the Manitoba parkland experience, like Don says, anglers will vote with their feet. The increased angler related tourism revenue could help offset the costs of poison.
Seriously, what else is there to do? You gotta kill the perch or kill the lake. Having a zero limit makes no sense in lakes already infested.
