All you tuna fishing persons, ever see this behavior in the linked video?

Saw that earlier.
All I can think of is has a parasite or maybe a hook in it's gut?
That there Tuna looked like he's tryin ta beach hisself!
Maybe it got disoriented by the shallow water. It certainly had a lot of power, not like it were sick or dying.
Weird, maybe it's in distress, like something wrapped around it's tail. :o
