While most mussels or many are endangered there are the invasive zebra mussels. The black and white does not sound too good. They had a huge outbreak in Virginia, and wiped them out completely with Potassium. It's non toxic but just destroys mussels. Potassium Chloride is also widely used as a water softener. You have to positively identify what you have as you cannot just completely eradicate an endangered species, or if they are invasive, state may do it for you. If they are just some common mussel, you can do it yourself and it won't hurt your fishes. And just regular bluegill won't help to keep them from coming back. Red Eared Sunfish are specifically equipped with bone crunching abilities or shellcrackers. Nice fish to stock anyway.
