湘华鲮是湖南特有的一种鱼，在沅水流域产量最高，以前当地老百姓经常能见到。但上世纪八十年代开始，由于修建电站阻断了它的洄游通道，加之环 境污染和过度捕捞，湘华鲮的数量急剧下降，一度面临濒危。现在之所以能再次出现在大众视野，与近些年我国大力推进生物多样性保护治理的努力是分不 开的。 通过数年不懈地技术攻关，研究人员摸索出了一整套湘华鲮的"驯养—繁殖—养殖"技术，成功把湘华鲮从灭绝边缘拉了回来。不过，要让像湘华鲮这样 的濒危物种延续，技术攻关只是第一步，要让它们真正能繁衍壮大，就要实现产业化养殖。 目前，随着我国经济社会发展，对生物多样性保护工作也提出了更高要求。对一些有开发利用价值的濒危物种，不仅要进行保护，还要让其繁衍壮大， 实现产业化来造福百姓。不过，湘华鲮的生长速度缓慢，要三年才能上市，这让养殖企业很担心利润问题，不敢轻易尝试。后来，怀化市政协委员、本土企 业家张在权决定试一试。 张在权投资建设了湘华鲮的保种基地、繁育基地和商品鱼养殖基地。当地相关部门也不断对湘华鲮养殖做知识普及和宣传，并提供一些政策支持，有越 来越多的养殖户陆续加入了进来。 央视网消息（焦点访谈）：5月22日是国际生物多样性日，在"万物共 ...
