| 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25d的调查捕捞，共作业124船次，累计捕捞时间462h，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21d，累计捕捞时间414．5h，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。 |

| We conducted a fishing survey for 25 days in all in Ma＇anshan, Wuhu and Tongling along the Yangtze river in May in 2006 and May in 2007, with performing for 462 hours for 25 times and following the saury fishing vessels for 310 times, and not a could be found. 230 person times were visited in the past two years. Not any message related to the capture of Yangtze river reeves shad in Anhui along the Yangtze river had been seen since 1994. Literature showed Yangtze river fisheries research institute of academy of fisheries sciences organized a large scale fishing for 93 times for 414.5 hours in all and no one could be found. Results indicated the Yangtze river reeves shad had been in an endangered state. Over fishing of parent Yangtze river reeves shads, loss of juvenile fishes, environmental pollution and destruction of hydrological conditions were the main reasons. There was no delay to protect the Yangtze river reeves shad. |
