| 摘 要： | 2006年5月和2007年5月,在安徽马鞍山、芜湖、铜陵等江段进行了为期25 d的调查捕捞,共作业124船次,累计捕捞时间462 h,跟随刀鱼渔船出江捕捞310次,未捕到鲥鱼(Macrura reevesii Richardson).2年共走访资深渔民230人次,结果表明,自1994年以来,安徽江段未曾有捕到鲥鱼的音讯.资料显示,中国水产科学院长江水产研究所于1996年组织渔民在峡江产卵场内进行试捕,共作业21 d,累计捕捞时间414.5 h,总作业93船次,结果未能捕捞鲥鱼.长江鲥鱼资源已成濒危状态,原因主要是鲥鱼亲体捕捞过度、鲥鱼幼体受到损害、水域环境污染、水文条件的影响,保护长江渔业资源刻不容缓.
