Well thank you Champlain Islander for this information. DTD river channel is full of these species so other fish species are threatened. In our waters we have carps, catfishes {also from USA}, pikes, walleyes, roaches, breams and some other species which English names I don’t know. Sunfishes are pests that eat other fish’s eggs. They are smaller then yours but very good disseminated and annoying.
Please when you go fishing next time think about this.
