OK, so what's a mooneye??
Just kidding. I did an image search for "goldeye" and found several photos and some fishing info. They look like an american shad with teeth (yikes!). Bet they are great fighters!
How big are the ones you're catching? The sites I checked out said they average 1 - 3 lbs, but one site listed a club record of 24 lbs 9 oz. WOW!
