Occurs in deep water. Spawns only around margin of Pyramid Lake in Nevada, USA but formerly made spectacular spawning runs up Truckee River in Nevada, USA. Populations were subject to intensive fishing in the 19th and early 20th century; habitats have been greatly altered by water development projects; species is now endangered (Ref. 47054).
出現於深水域。 只在美國內華達州的金字塔湖的邊緣的周圍產卵但是在美國內華達州的 Truckee 河上面從前進行大規模產卵小支流。 族群是受在 19 世紀與 20 世紀初中密集的漁補支配; 棲息地曾經被水發展突出劇烈改變; 種是現在瀕臨絕種的。 (參考文獻 47054)
