释
dabry's sturgeon
达氏鲟
硬骨鱼纲(Osteichthyes)鲟形目(Acipenseriformes)鲟科(Acipenseridae)鲟属(Acipenser)一种。又称长江鲟、沙腊子、小腊子。为中国特有物种,是鲟科鱼类中淡水定居型鱼类,属长江大型经济鱼类之一。因外形同分布于长江中的中华鲟很相似,渔民把个体大、洄游性的一种(中华鲟)称“大蜡子”,而把体型较小,淡水定居性的一种(达氏鲟)称“沙蜡子”“小蜡子”。鳇、鳣、鱏、玉版、鮥等词语在古籍或俗语中作为鲟鱼的通称,有时也用来指达氏鲟。1989年被列为国家一级重点保护动物,也是世界自然保护联盟(IUCN)列为极危(CR)物种,濒危野生动植物国际贸易公约(CITES)附录II保护动物。
