11月18日，武汉渔政码头热闹非凡。随着放流箱缓缓倾斜，一尾尾胭脂鱼和长吻鮠欢快 地跃入长江怀抱。这是武汉市水生生物增殖放流（第二批）活动现场，共向长江"冬补"了40 万尾珍贵鱼苗——胭脂鱼和长吻鮠各20万尾。 这次放流的"主角"之一胭脂鱼，是长江鱼类中的"明星"。它外形漂亮，姿态优雅，是中 国特有的淡水珍稀物种，更是国家二级保护野生水生动物。成年后，它们身上出现鲜艳的胭 脂色条纹，这种"亮色"在长江鱼类中并不多见，因此赢得了"淡水美人鱼""中国美人鱼"的美 誉。不过，它们在野外成熟期较长，雄鱼要5年以上，雌鱼甚至要7年以上才能繁育后代。 "这次放流的胭脂鱼，都是我们自己繁育的。"武汉青鱼原种场负责人丁运敏介绍。该场 持续多年攻关胭脂鱼人工繁育技术，利用自己培育的亲本胭脂鱼，去年成功繁育了200万尾 鱼苗，今年又繁育了100万尾，为长江增殖放流提供了有力支撑。 武汉生态志愿者们放流胭脂鱼。 今年6月6日"全国放鱼日"，同样在武汉渔政码头放流了国家一级保护动物中华鲟10210 尾、国家二级保护动物胭脂鱼15万尾、湖北省重点保护水生野生动物长吻鮠30万尾，以及青 鱼300万尾、草鱼200万尾、鲢鱼200万尾、鳙鱼 ...
