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 / 深度上下限 / distribution range
生态学
海洋; 淡水; 半咸淡水 底中水层性; 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。

背的软条 (总数) : 13 - 15; 臀鳍软条: 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).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Possesses a particular diet due to poor insular ichthyologic fauna; its food consists mainly of tadpoles, insects and urodela (Ref. 11941).
持有一个特别的食性由于少量的岛鱼类学的动物相。 它的食物主要地蝌蚪，昆虫与 urodela 组成。 (参考文献 11941)
