check out this poor fish

I got a 25 # bass SE of Monomoy with a similar mark like that, but it was on its' underbelly, just aft of the gills. Healed up pretty good, my guess is it was one of those fat Monomoy seals.

When I was a kid, I remember my father would go out on the Trader Five, out of Harwichport, for swordfish tournaments. One year he was the angler for what would have been the tourney winning fish. Unfortunately the fish got dinged by one of the wheels (propellers), which disqualified the fish. I remember the pictures, and they did not look like that scar. (I also remember the owner blaming the captain for allowing the fish to get under the boat.....)
