Fish roast brilliantly, and you actually can tell when a trout is done. Put a meathook through the lower jaw and hang in front of a fire, twiddling regularly with the swivel. Place a plate under the fish. When it is cooked, the trout falls off the hook onto the plate. You can cook any fish by this method, though I will agree that whitebait are fiddly.
