Like it or not suckers have been around longer than most species of trout in AB. They serve an important role in all aquatic ecosystems where they are found. Will they eat the eggs of other fish? yes...but so do other trout. Brookies are a large part of the reason our bull trout populations are doing so poorly. Killing them is pointless and stupid. People kill them because they are ugly...and because there is some redneck myth about how they destroy fisheries...its all BS. They are there for a reason so C&R, or fish with hardware if you dont want to catch them.
If I see anyone killing suckers, im taking a page out of the Best Guide fishing manual and throwing them and their gear into the water.....
