What kind of trout is this?

CUTTHROAT NO DOUBT Not to be rude or offensive, but anyone that would have any question on what species of fish that is should not be fishing a lake where it is required to know. IT took less than a second looking at the thumbnail picture to make the call. As mentioned before by another poster, I see far too many people keeping "in the slot cutts" and even arguing that they are rainbows. But maybe they should let people keep a couple of them and go home, many kill more than 2 every trip out due to mishandling. But that is another story for another day.
