The article says that its possible the hurricane displaced it from a pond into the lake. I would say that could be feasible. If that is the case, and the previous owner of that fish see's this story, they are going to be very unhappy people.
And we wonder why....the fed governemnt wants to pass laws.....when stupid people put non native fish in lakes and streams and rivers it destroys the eco balance.
Granted I would prefer that they kept the fish alive and found a home for him....but it just ruins this hobby when idiots turn fish loose!
