Freshwater Drum/Sheepshead?

[abc91686]

Hey everyone I was just wondering if my initial reaction to what this fish was was indeed correct. I caught a crayfish in the river and put it on my hook with a bobber about 4 feet above the bait and tossed it into a pool about 5' deep only 15' off the bank of the river. Let it sit for a while and actually saw the bobber go under from our horseshoe pits and ran down to fight the fish. I only have 4 lb test on the reel, so it was a really good fight. Its the biggest fish I've ever caught on the allegheny! I revived it after a photo or two and he just swam back off. For future reference are these guys any good to eat? Thanks for your responses in advance.
