Descrição breve
Morfologia | Morfometria
Espinhos dorsais (total): 0; Raios dorsais moles (total): 12-16; Espinhos anais 0; Raios anais moles: 12 - 16; Vértebras: 56 - 59. Diagnosis: Salmo pallaryi differs from all other Salmo species and archaic trouts, except for S. platycephalus, by the overall dusky brown or blackish colour pattern, without contrasting colouration on trunk and fins in adults; it is most easily distinguished from S. platycephalus by the deep and narrow, sometimes pointed snout and large orbit, 25-31% of head length vs. the broad and flat snout and small orbit, 22% of head length, and more numerous scales, usually 18-20 vs. 16, between adipose fin and lateral line; it differs further in having number of anal fin pterygiophores 12-14, other Salmo species and archaic trouts have 10-12 (Ref. 55619).
It feeded on amphipod crustaceans and insects (Ref. 55619). Salmo pallaryi most probably spawned during late summer or early autumn (Ref. 55619). Supposed extinction of S. pallaryi was probably caused by altering trophic condition as a result of introduction of Cyprinus carpio in 1934 to Lake Sidi Ali (Ref. 50056, 55619).
