Sharing an interesting article about rotenone laced pellets to selectively target carp. I'm surprised the company making the pellets didn't continue to try to add more fish meal or other 'flavorants' to cover the 'taste' that made fish spit it out. There is a fairly large need for a selective pellet based fish removal tool. Who ever made my Optimal make my hands smell awful at the same time made fish go crazy over its taste. They probably could take over this research!
