Note:
棕鱒廣泛分佈於歐洲地區的溪流、湖泊，其體型和體色會因為環境因素而有所變異。英國溪流流幅小，因此野生棕鱒的普遍釣獲體型在15到30公分左右，而湖產或人工放流者則可達40～50公分。棕鱒的掠食性格明顯，除了補食水生昆蟲和小魚苗外，一些體長60、70公分以上的大型棕鱒，甚至會掠食落水的小老鼠和青蛙。
Brown trout are wide spread in streams and lakes of Europe. The color and size of brown trout varies from different habitats. The streams in England are usually small, thus the wild brown trout often caught in the size of 15 to30cm. Some of artificial propagated trout or the one which lives in lake can grow up to 40 to 50cm. The nature of predator of brown trout is significant, it takes aquatic insects and fish fry, besides, some large size trout which maybe over 60 or 70cm even takes small mice and frogs.
