Etymology: Salmo: Latin, salmo, Plinius = salmon (Ref. 45335).
More on author: Duméril.
Issue
A better resolved species level taxonomy and more detailed morphological examination of peri-Mediterranean and African 'macrostigma' trouts is needed and feasible.
Environment: milieu / climate zone / depth range / distribution range
生態學
海洋; 淡水; 半鹹淡水 底中水層性; 溯河洄游 (Ref. 51243). 深水域
Africa: restricted to Algeria (Ref. 13696, 55619, 59043, 87713), also in Mediterranean basins of Morocco (Ref. 107622). The other peri-Mediterranean populations referred to as Salmo macrostigma belong to several species (Ref. 87713).
歐洲: 在地中海中已知只來自 Corse 的島了。 不出現在歐洲的大陸。 或許受益於環境規章通過了 8/12/88之上在法國。 需要更多的研究。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 18 - ? cm

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 13 - 15; 臀鰭軟條: 11 - 13; 脊椎骨: 57 - 58. Diagnosis: dorsal fin slightly higher than long; located more posteriorly than in other Salmo species; caudal fin more forked than other Salmo species; 8-12 round, black spots (parr marks) on sides (Ref. 4904, 52923, 94703, 94704), which are more prominent in juveniles and are retained in adults (Ref. 55619). Low gill raker count and dark spots on sides distinguish it from S. akairos; it differs from S. trutta in slightly lower vertebral count and pyloric caeca counts, and having the parr marks more conspicuous; 10-11 anal fin pterygiophores (Ref. 55619). 14-17 small scales between adipose fin and lateral line (Ref. 1878, 52923, 55619).
Possesses a particular diet due to poor insular ichthyologic fauna; its food consists mainly of tadpoles, insects and urodela (Ref. 11941).
持有一個特別的食性由於少量的島魚類學的動物相。 它的食物主要地蝌蚪，昆蟲與 urodela 組成。 (參考文獻 11941)
