生物学特性     字汇 (例如 epibenthic)

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).

在淡水中度过 1 到 5 年与在咸水中 6个月到 5 年。 (参考文献 51442) 在 3-4 年中成熟。 (参考文献 6885) 它在河 (参考文献 30578) 中繁殖, 通常超过定时。 (参考文献 51442) 它偏爱寒冷,溶氧量高的丘陵地水域,虽然他们的包容限制是低于虹鳟的而且喜欢在多山的区域中的大溪流以足够的覆盖形成水下的岩石,堤岸下与上悬的植物.(参考文献 6465) 生活历史而且产卵行为是类似鲑鱼 Salmo salar.(参考文献 51442) 每个母鱼生产大约 10.000个卵。 (参考文献 35388, 参考文献 51442) 主要日行性.(参考文献 682) 稚鱼主要捕食水生与陆栖的昆虫; 成鱼捕食软件动物,甲壳动物与小鱼。 (参考文献 26523, 参考文献 51442) 在市场上销售熏制或新鲜了; 油炸后食用, 火烤,煮沸,在微波煮了, 而且烧烤了。 (参考文献 9988)

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼

Female covers the eggs by restirring the sand and fine gravel (Ref. 9696). After hatching at 12 mm, larval brown trout remain in the gravel for 2-3 weeks until they are about 25 mm long, when they emerge to begin feeding in the water column. Brown trout are territorial and begin establishing territories as juveniles. Juvenile trout from lake populations move from their natal inlets to lakes during the first 2 years of life (Ref. 6390).歐洲與亞洲: 歐洲的在西北部海岸.(參考文獻 51442) 在美國 (參考文獻 5723) 與澳洲各處廣泛地引入。 引入後的一些國家報告不利的生態衝擊。
