Catch and Release

I myself  am a "Catch and Release" angler. That dosent mean I dont keep a few for shore lunch. I like to call it "selective harvest". The Ministry has limits and "slot" sizes for all species of fish to keep the fishery healthy for generations to come..

Make sure your familiar with your regions rules and regulations... The authority in your area can put a quick stop to your fishing, and hit you with some pretty hefty fines!

The bigger the fish, the worse it is for eating!  .... A 2 pound Walleye tastes much better than a ten pounder.
Which brings me to the point " Let go of the breeders"!  any female fish of good size, of any species should be let go....These are the "Breeders" and these fish insure that we have great fishing for future generations!
Take a picture, and then let go of the "Breeders"

Here is an example that catch and release does work

I caught this smallmouth on 3 different occasions in the same area. The only way I knew was the chunk taken out of its lip.
