I will help out Chris on his last question. Several species of fish in Lake Erie have been reported to eat Zebra mussels, FW drum, perch, pumpkinseeds come to mind. I think your RES will eat the smaller individuals of Zebra mussels-possibly 1/8"-5/32" in length. I have no ideas how growth rates will be for RES on a diet of Zebra mussels. That would be good data to report -publish.

One study stated that RES did eat ZM . EW
