I wonder where those marks on his back are from? This isnt the only fish ive caught this year to have some sort of attack marks. In fact about ten minutes after i released this fish, i caught a brown trout that had a big scratch down her side.

Did it look like a pick mark that a bird would make, or was it more like an inscisor tooth from the weasel family..... mink , marten fisher?
