Fish taste organs are sensitive chemical receptors (taste papillae) that perceive gustatory stimuli. Taste organs in most fish are located in the oral cavity (about 20 thousand), sometimes at the tips of the antennae, gill lobes and lips (burbot, whitefish, cod), in the pharynx, fin rays, less often on the body surface (tench, carp). Fish are able to distinguish the basic taste sensations - sour, salty, bitter and sweet.
