Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Northeast Atlantic: southward to southern Norway; Iceland; southern Greenland. Non-migratory and land-locked relict populations south to the British Isles and central France. Reported from Greece (Ref. 27724), Estonia (Ref. 33247) and Argentina (Ref. 9086). Elsewhere circumpolar. Likely to benefit from environmental regulation passed in France on 8/12/88 (Ref. 2163). Considered a synonym of Salmo trutta trutta by Kottelat (Ref. 13696).

Biology     Glossary (e.g. epibenthic)

Repopulation of stocks usual in Europe. Original population still exists in the island of Corse in the Mediterranean Sea (Ref. 682). Often found in fast-flowing streams of mountain and sub-mountainous regions and sometimes even valleys (Ref. 9696). Feed on benthic invertebrates, insect larvae, aerial insects (in rivers) and mollusks. In addition, adults consume fish and frogs (Ref. 30578). Utilized fresh and smoked; eaten fried, broiled, microwaved and baked (Ref. 9988).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00663 (-0.09141 - 0.10467), b=3.05 (2.98 - 3.12), based on LWR estimates for species & genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.55 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=1-5; tmax=8; K=0.21; Fec=1,000).
Vulnerability (Ref. 59153):  Moderate vulnerability (45 of 100) .
Price category (Ref. 80766):   Very high.
