🐟Cutthroat trout
克拉克大麻哈魚（学名：Oncorhynchus clarkii），俗称割喉鱒（英語：cutthroat trout），是鲑科麻哈魚屬的一種溫帶淡水辐鳍鱼，分布於北美洲太平洋西北地区、科迪勒拉山系（包括大盆地）和密苏里河上游流域，在北美曾有过仅次于湖鳟的栖息范围，可做為適合各种烹飪方式的食用魚，另亦可做為游钓鱼（特别是飞蝇钓）和觀賞魚。 割喉鳟的拉丁文种小名“clarkii”源于刘易斯与克拉克远征，原因是探险家威廉·克拉克在1805年的远征日记中首次记载了在现今蒙大拿州大瀑布城附近的密苏里河上游中看到的一条割喉鳟；割喉鳟的亚种之一西坡割喉鳟（O. c. lewisi）则是以梅里韦瑟·刘易斯命名。而俗名“割喉鳟”则是源于户外运动作家查尔斯·哈劳克（Charles Hallock，1834～1917）于1884年在为 《美国钓客》（The American Angler）杂志写的一篇文章中对其的形容。
