As a youth (Tri-Cities) we treated this species with disdain. It wasn't until I became an adult, and married into a family of chefs that I discovered their value as a food species. Carp--when kept in clean, cold running water--is somewhat sweet, and very expensive. They do have a lot of bones, which puts off a lot of people. They do not need to be deep fried a la Chinoise, but can be served raw (or Peruvian ceviche); note, however, raw fish from fresh water is highly risky because of the chance of parasites.
As for me, if I think back to the warm waters of the Yakima River delta (confluence with the Columbia), there is no way that I would eat them. Your choice!
