简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 44-48; 臀鳍软条: 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).
在肛门与臀鳍之间的一条腹部中央的联机区别的特徵为这 2 列的 4 到 8个骨质板了, 在背鳍中大约 45个鳍条.(参考文献 27547) 灰色或上方褐色的, 腹面灰白的; 鳍灰色.(参考文献 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).
在海洋中度过它大多数的时间, 通常接近海岸.(参考文献 27547) 进入大河的河口而且向内陆长距离移动产卵.(参考文献 5723) 个体大于 48.3 公分主要捕食鱼; 较小的一些主要捕食宝刀鱼, 也捕食小型甲壳动物，其他的昆虫与软件动物.(参考文献 1998) 就在产卵之前，进食停止。 (参考文献 1998) 优良的食用鱼，那是卖生鲜、烟熏或冷冻的.(参考文献 9988) 卵在市场上销售如鱼子酱。 (参考文献 1998) 在以前，气囊被制成鱼胶。 (参考文献 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)
