Etymology: Salmo: Latin, salmo, Plinius = salmon (Ref. 45335).
Eponymy: Paul Maurice Pallary (1869–1942) was a French-Algerian malacologist who collected the type specimen of the barbel. [...] (Ref. 128868), visit book page.

簡短描述

背棘 (總數) : 0; 背的軟條 (總數) : 12 - 16; 臀棘: 0; 臀鰭軟條: 12 - 16; 脊椎骨: 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).
有別於所有的其他 斑鱒屬 種, 除了 S. platycephalus, 藉由全身暗褐色或者黑色的彩色斑紋, 沒有對比鮮明的顏色在軀幹與鰭上當成魚時。 斑鱒屬 pallaryi 容易地最被與 S. platycephalus 區分藉由深的而且狹窄的, 有時尖的吻而大的眼窩 22% 的頭長; 而且在脂鰭與側線之間的眾多鱗片 (通常 18-20, 對 16)。 斑鱒屬 pallaryi 在臀鰭支鰭骨 12-14 的數字中不同進一步, 典型地 13; 其他的 斑鱒屬 種典型地有 10-11, 很少地 12.
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).
