Unfortunately there will always be people who do not abide by the laws and what is equally unfortunate is there are a lot of people who for some reason think that if they own property on a lake then the rules really don`t apply to them, I know of several who fall into this category.
Having said all that the decline of the Walleye population over the last couple of decades is due in large part IMHO to the introduction of the Crappie.
The Crappie are thriving and the Walleye population is taking a severe beating. Personally I think that there should be no limits on both the white and the black Crappie.
I know "my" weekend lake used to a very good Walleye lake and a pretty good Musky lake but the Pike and Crappie have pretty much destroyed the Musky and Walleye fishery.
I know Crappie are caught in my lake in the spring and their bellies are full of Walleye fry!
I think the problem can be fixed but unfortunately it`s going to take someone in the Ministry with some stones to make some tough decisions, the most recent changes to the regulations indicate to me that I should not hold my breathe waiting for the right thing to be done!!!
