The only definitive way to tell is the liver esp in smaller big eyes. One has dark stripes the other doesn't. To be honest I never caught a big eye less than 110#.
I have opened both them up and compared the two and it is very different and easy to tell.
Trying to tell from banding and fins is really sketchy.
No matter it sounds like a great trip. Personally I don't see the need to kill 83 fish but it sounds like you had plenty of action. Heading out there Fri/Sat and I hope to catch one!
