简单描述 型态特徵 | 形态测量图

背棘 (总数): 0; 背的软条 (总数): 12-16; 臀棘 0; 臀鳍软条: 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).
有别于所有的其他 斑鳟属 种, 除了 S. platycephalus, 藉由全身暗褐色或者黑色的彩色斑纹, 没有对比鲜明的颜色在躯干与鳍上当成鱼时。 斑鳟属 pallaryi 容易地最被与 S. platycephalus 区分藉由深的而且狭窄的, 有时尖的吻而大的眼窝 22% 的头长; 而且在脂鳍与侧线之间的众多鳞片 (通常 18-20, 对 16)。 斑鳟属 pallaryi 在臀鳍支鳍骨 12-14 的数字中不同进一步, 典型地 13; 其他的 斑鳟属 种典型地有 10-11, 很少地 12.

生物学特性     字汇 (例如 epibenthic)

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).
