Fished on Logan Martin in Alabama yesterday. One of the fish that I caught had about a six inch Lamprey stuck to it's dorsal fin. I was surprised at how much blood it could draw through the fin. Note the red spot on it's fin in the attached pic.
Wondered if anyone else has see these things on Logan Martin. This is my first encounter with one however I have caught fish with these red sores on them before. So maybe they had Lampreys stuck to them but got pulled off when I reeled them in. I hope these things don't start hurting the population. Nasty looking thing!
