Muskies yes, they shouldn't have too much of an impact of our native fish, especially in this climate. However, I'm not sure i would go along with stipers not causing problems. Stripers, especially mature stripers can eat a lot fish, and not just bait fish. They typically eat about 1/2 or more of their weight in fish every day from what i have researched and talked to biologists. I have definitely noticed a difference in walleye fishing at Bull Shoals since all these record fish have been making their way through the lake. They can do some damage in certain enviroments. Just my opinion.
