Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 16; Duri dubur: 0; Sirip dubur lunak: 12 - 13; vertebrata, bertulang belakang: 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).
Body shape (shape guide): fusiform / normal.
Analysis of stomach content revealed Cyclops, terrestrial arthropods and a dense mat of filamentous algae and diatoms (Ref. 55619). Spawning period is in late autumn (Ref. 55619).
