背棘 (总数) : 0; 背的软条 (总数) : 16; 臀棘: 0; 臀鳍软条: 12 - 13; 脊椎骨: 56 - 58. Diagnosis: Salmo akairos differs from all other Salmo species and archaic trouts by the combination of contrasting black and white leading edges on dorsal and anal fins and the lack of dark spots on the sides of the body; high number of dorsal fin pterygiophores, 14-16 is distinctive, as other Salmo species and archaic trouts have modally 12-13; high number of gill rakers, 19-23, is also diagnostic with slight overlap in comparison with S. trutta often having a colour pattern on the fins similar to that of S. akairos (Ref. 55619).
与所有的喧扰区分 斑鳟属 种与已废的鳟鱼藉由在背鳍与臀鳍上对比黑白的前缘组合与那缺乏深色的斑点在身体侧边上。 背鳍支鳍骨 (14-16) 与鳃耙 (19-23) 的高数字的高数字.(参考文献 55619)
