🐟Brown trout

Salmo trutta Linnaeus, 1758

褐鳟（学名：Salmo trutta，英語：brown trout），為鮭形目鮭科鳟属的一種具有一定广盐性的淡水輻鰭魚，广泛分布于欧洲北大西洋沿海水系以及包括西亚和中亚部分地区在内的环地中海/黑海沿岸和内陆河流，是欧洲最常见的一种鳟鱼，也是欧洲鳟的模式种。 褐鳟的种小名trutta是拉丁语中“鳟鱼”的意思。美国鱼类学家罗伯特·J·本克（Robert J.Behnke）所给出的解释是褐鳟（指海中栖息洄游的亚种——海鳟）是卡尔·林奈在1758年版《自然系统》中描述的第一种鳟鱼，也是第一种以二名法命名的鳟鱼。林奈当时还命名了另外两个褐鳟的亚种：河鳟（当时称作Salmo fario） 和湖鳟（当时称作Salmo lacustris）。
