Here in my area we also have Anhingas, which some might mistakenly call cormorant. These birds however do not have the classic hooked bill of a cormorant but also possess a long skinny neck made for ringing.
Locals call them Water Turkey, but I’m not sure why. I imagine they probably taste like a foul greasy old rotten mud duck found dead by the road two days too late. As with most birds they likely are protected and should not be shot like one might do with snakes that are also protected. Which is exactly why I prefer a nice brush axe. Neighbors.
My birds also eat snakes and alligators and crawfish. Mostly though I imagine them swallowing trophy bass and croppie. They spear the fish and if small, swallow them on the surface, but when large, taken ashore to be pummeled to death against a tree branch, then swallowed.
Your fish seems to have a gouge in it as if a hooked bill creature lost it’s grip. I’d choose six shot to ensure penetration through those swim feathers.
