The incidental White Bass caught deepwater Pickeral trolling on Lake Erie were actually pretty decent on the table, White Perch on the other hand tend to be found in much warmer, discolored and poorer quality waters and I have found their flesh of poor quality. Some of the Erie White Bass were a real good size too.
edit: Now that I think of it , we called them Silver Bass not White Bass, same fish though. Probably if they had come from the luke warm water where I had White Perch from they would have not been a palatable as they were from 60 something degree water where the Pickeral were.
