Gandolf, Google "Cleaning trout", and you will get at least 12 video's. many similar, but many with their own twists. do the same for "Cooking Trout" and the list gets even larger.

While I'm not attempting in any way to suggest that folks should keep rather than release their fish. Folks should know the signs of a mortally wounded fish. The one obvious sign is when a fish is bleeding from the gills, it will not survive. It may swim off from your hand, but it will die. For them, that is an open chest wound with a punctured lung. Personally, we owe it to th fish as good stewards to kill and eat that fish. My personal rule of thumb (And this is from personal experience, not a scientific study), is if after 10 minutes of reviving a fish, it still cannot right itself, or is still gasping, it's going to die. To do otherwise is no different than saying "Oh, this one's gonna die, and throwing it up on the bank." Same result. You killed it, and gave it to the raccoons.
