What we call a sheepshead down here is a salt water fish with wide bars much like want we call a butterfly drum which are great eating. Sheepshead I have caught and they are called that because of their teeth. Black bars over a silver side fish. This was what we down here call a freshwater drum and pretty much all gray. Some people do eat a sheepshead like we have in salt water and they are not all bad. I just know this thing has other names, but not sure which one it is. It did have enough teeth that stopped me from lipping him, but not like a sheepshead.

Good grief I just did a search on fresh water drum and can't believe it has so many names and I guess basically all the same. Even your sheepshead name is in there, but our sheepshead is way different. Only mine was more gray than gold.
