I am somehow reminded of my grandfather's recipie for fresh caught campfire cooked carp.
stuff with onions lemon and dust with salt,pepper and flour.
find 1x6" board.
Nail carp at head and tail to board.
prop or bury one end of board so fis is facing campfire at about 45 degress abouth 12" from good banked coals
allow to cook for 1/2 hr or more, keeping hot coals at consistant distance,for even cooking.
When carp is done remove carp from board, cut board into bite-sized pieces and serve over rice.
