Issue
The species Salvelinus aureolus Bean, 1887 is considered as valid in Eschmeyer (CofF ver. May 2011: Ref. 86870) following Fuller et al. (1999: Ref. 87253). Treated as synonym of Salvelinus alpinus oquassa by Qadi (1974: Ref. 87252); and probably a synonym of Salvelinus alpinus

Short description

Dorsal spines (total): 4 - 5; Dorsal soft rays (total): 8-16; Anal spines: 3-4; Anal soft rays: 7 - 15; Vertebrae: 62 - 68. Distinguished by the presence of 23 to 32 gill rakers, 37 to 75 pyloric caeca and, on the sides and back, pink to red spots, the largest of which are usually larger than the pupil of the eye (Ref. 27547). Lateral line curves slightly downward from the head (Ref. 27547). Pelvic fins with axillary process; caudal emarginate (Ref. 27547). Color highly variable, depending on location, time of year and degree of sexual development. In general, back is dark, usually rather brown but sometimes with a green cast; the sides are lighter, belly pale; sides and back are liberally sprinkled with pink to red spots, the largest spots along the lateral line usually larger than the pupil of the eye; forward edges of pectoral, pelvic and anal fins, and sometimes the caudal, with a narrow white margin; fins pale in young, dorsal and caudal dark in adults (Ref. 27547). Spawning adults, especially males, are brilliant orange-red to bright red on the ventral side and on the pectoral, pelvic and anal fins. Young have about 11 dark parr marks on each side (Ref. 27547). Caudal fin with 19 rays (Ref. 2196).

Anadromous forms spend a considerable time of their lives at sea; non-migratory populations remain in lakes and rivers (Ref. 4779). Found in rivers, estuaries and lakes with cold, clear water. Occurs mainly in lakes. At the sea, lives along coasts (Ref. 59043). Inhabits deep runs and pools of medium to large rivers, and lakes (Ref. 5723). Nerito-pelagic (Ref. 58426). Freshwater populations feed on planktonic crustaceans, amphipods, mollusks, insects and fishes (Ref. 4479). Anadromous individuals feed little in freshwater and never feed during migrations. Spawning usually takes place on pebble to stone bottom in lakes. Riverine stocks spawn in rivers with slow current (02.-0.8 m/s), but there are some riverine anadromous stocks (in Norway) which spawn in fast-flowing waters of riffles (Ref. 59043). Extremely sensitive to water pollution (cold water and oxygen oriented) (Ref. 2163). Marketed fresh, smoked, canned (Ref. 27547), and frozen. Eaten sautéed, broiled, fried, microwaved and baked (Ref. 9988). Parasitized by tapeworm (Ref. 37032).
