簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 44 - 48; 臀鰭軟條: 28 - 31. Distinguished by the 2 rows of 4 to 8 bony plates on a midventral line between the anus and anal fin, and about 45 rays in the dorsal fin (Ref. 27547). Gray or brownish above, paler below; fins gray (Ref. 27547). Barbels situated closer to snout tip than to mouth; no obvious scutes behind dorsal and anal fins (Ref. 86798).
在肛門與臀鰭之間的一條腹部中央的線上區別的特徵為這 2 列的 4 到 8個骨質板了, 在背鰭中大約 45個鰭條.(參考文獻 27547) 灰色或上方褐色的, 腹面灰白的; 鰭灰色.(參考文獻 27547)
Spends most of its time in the sea, usually close to shore (Ref. 27547). Enters estuaries of large rivers and moves far inland to spawn (Ref. 5723). Individuals larger than 48.3 cm feed mainly on fishes; smaller ones feed mainly on chironomids, but also takes small crustaceans, other insects and mollusks (Ref. 1998). Feeding ceases just before spawning (Ref. 1998). Excellent food fish that is sold fresh, smoked or frozen (Ref. 9988). Eggs marketed as caviar (Ref. 1998). In the past, the airbladder was made into isinglass (Ref. 27547).
在海洋中度過它大多數的時間, 通常接近海岸.(參考文獻 27547) 進入大河的河口而且向內陸長距離移動產卵.(參考文獻 5723) 個體大於 48.3 公分主要捕食魚; 較小的一些主要捕食寶刀魚, 也捕食小型甲殼動物，其他的昆蟲與軟體動物.(參考文獻 1998) 就在產卵之前，進食停止。 (參考文獻 1998) 優良的食用魚，那是賣生鮮、煙燻或冷凍的.(參考文獻 9988) 卵在市場上銷售如魚子醬。 (參考文獻 1998) 在以前，氣囊被製成魚膠。 (參考文獻 27547)
Adults return to the sea after spawning (Ref. 27547). Spawning frequency interval every 4 years for younger females and every 10-11 years in older females (Ref. 1998).東太平洋: 阿拉斯加灣到蒙德勒，美國加州。 陸封的在蒙大納的哥倫比亞河流域, 與也許在美國加州的沙斯塔湖。 棲地移至科羅拉多河下游，美國亞歷桑那州了。 記錄來自墨西哥的下加利福尼亞北部了。 (參考文獻 2850,27436) 被認為是易受傷害的在加拿大.(參考文獻 6866) 國際間的買賣限制。 ( 引用2, 自從 1.4.98 以後)
