There are lots of fish called by another name like this thread has lead to pointing out.
There is the yellow perch native to North America, it is a northern fish, not native to the South. Colt.45 in the north where the yellow perch is a native species and a lot of people fish for them there. I caught some while working in Michigan in 98. Good eating little fish.
Many of us grew up fishing for and catching and eating "perch" that in reality are sunfish of some sort like the large mouth bass is a member of the sunfish family as well as bluegill, red ear, Worm mouth....
One thing about all of those, if they are from clean water they are all good eating, especially baby bass
