I don't remember hearing about that.
That's creepy!
Every once in a while I see a ghost trout swim by.
I read an article in In-Fisherman once where Doug Stange or one of the other guys had a musky do the same thing to them while they were fishing open water on some lake up north. The fish actually stuck his head out of the water and clacked his jaws. He said he was afraid to tell anyone as he was afraid someone would think he was crazy.
