Gymnocephalus ambriaelacus is a species of freshwater ray-finned fish, a ruffe, from the family Percidae which is endemic to Lake Ammersee, in the upper Danube basin in southern Germany. This species can reach a length is 11.7 centimetres (4.6 in) (SL).[2] The species is classified as Critically Endangered as its population is declining following the introduction of the ruffe (Gymnocephalus cernua).[1] Some authorities suggest that this taxon may be synonymous with the Balon's ruffe (G. baloni).[3]
