Descrição suscinta

Espinhos dorsais (total): 3 - 4; Raios dorsais (total): 10-15; Espinhos anais 3-4; Raios anais : 9 - 14; Vértebras: 57 - 59. Fusiform body (Ref. 51442). Head little and pointed (Ref. 51442). Mouth large, extending mostly after the eye and has well developed teeth (Ref. 51442). Teeth on shaft of vomer numerous and strongly developed (Ref. 7251). Caudal fin with 18-19 rays (Ref. 2196). Caudal peduncle thick and rounded (Ref. 51442). Little scales (Ref. 51442). Body is grey-blue colored with numerous spots, also below the lateral line (Ref. 51442). Blackish colored on upper part of body, usually orange on sides, surrounded by pale halos. Adipose fin with red margin.

Found in streams, ponds, rivers and lakes (Ref. 5951). Individuals spend 1 to 5 years in fresh water and 6 months to 5 years in salt water (Ref. 51442). Juveniles mature in 3-4 years (Ref. 6885). Lacustrine populations undertake migration to tributaries and lake outlets to spawn, rarely spawning on stone, wave-washed lake shores. Spawns in rivers and streams with swift current, usually characterized by downward movement of water intro gravel (Ref. 59043). Spawning takes place normally more than one time (Ref. 51442). They prefer cold, well-oxygenated upland waters although their tolerance limits are lower than those of rainbow trout and favors large streams in the mountainous areas with adequate cover in the form of submerged rocks, undercut banks, and overhanging vegetation (Ref. 6465). Life history and spawning behavior is similar to the salmon Salmo salar (Ref. 51442). Each female produces about 10.000 eggs (Ref. 35388, Ref. 51442). Mainly diurnal (Ref. 682). Sea and lake trouts forage in pelagic and littoral habitats, while sea trouts mainly close to coast, not very far from estuary of natal river (Ref. 59043). Juveniles feed mainly on aquatic and terrestrial insects; adults on mollusks, crustaceans and small fish (Ref. 26523, Ref. 51442). Marketed fresh and smoked; eaten fried, broiled, boiled, cooked in microwave, and baked (Ref. 9988).
