However, I have seen Zebra (or Quagga) mussels in the stomachs of thousands of other Lake Erie fish species including: Freshwater drum (Sheepshead), Lake whitefish, Yellow perch, Pumpkinseed sunfish, Bluegill, Smallmouth bass, Round goby, Channel catfish- but never Walleye. When Freshwater drum eat mussels, their skin often takes on a shade of gold, compared to the usual silver/gray hue. If there were indeed mussel shells in the walleye stomachs, my theory is that they are inadvertently eating mussels as they inhale Round gobies from the rocks, but not deliberately seeking them, like the other species mentioned are known to do. Take pictures next time!
Nicely done and great report as...
