I’ve been jabbed in the foot and ankle by several catfish in the past. Hurt like hell. I’m thinking this kid picked up the catfish and then slipped or tripped and fell on top him and getting his chest impelled by the sharp dorsal fin.
Jeez! Meant impaled.
I had a fin from a hardhead get jammed into my thumb. Right hand. My whole arm went numb for a couple of hours.
That is what it sounds like, a dorsal fin bone. The whiskers couldn’t do that.
