Koi is the Japanese word for carp. Apparently, the carp all got together and hired a PR firm and after extensive research decided that they would get more traction in the U.S. if they went by the Japanese name rather than plain old carp. In ancient times, when I was a Boy Scout, I learned about carp. My Scoutmaster told me that when you went fishing for carp, if you caught one, you would gut it, spread the fish out on a pine board and cook it until it was done and then eat the board. I think this came from the feeding habits of the carp which I will not go into in a family rated blog.
