A disaster. 
A disaster.

1:50 July 20, rescue teams received flood control headquarters command, geheyan reservoir area will start a new round of flood discharge schemes, waste discharge at any time to increase to more than 7000 cubic metres per second to waste discharge of 10000 cubic meters per second, requiring all emergency rescue ship nearby suspended flight on standby. A lot Qingjiang branch floating cages come from.
The gaobazhou cages in the reservoir area flood losses of hundreds of millions of Yuan, generation of Zhang Huiyun White Duck NAO village is one of the hardest-hit areas. 14 total cage of her home, the flood resulted in the cage all damaged about 3,000 pounds of farmed fish were washed away.

湖北一水库泄洪,万吨鲟鱼逃逸，将导致长江生态灾难|鲟鱼|逃逸|中华鲟_新闻资讯
湖北一水库泄洪万吨鲟鱼逃逸 9月20日，清江（长江支流）梯级水电站泄洪。 7月19日，受强降雨影响，隔河岩水电站大坝18年来首次泄洪。当日晚上，来势凶猛的洪峰一路横扫河中养殖的数百口网箱。 大量网箱从清江支汊漂来。 80后张会云所在的白鸭垴村是此次重灾区之一。她家共有网箱14个，此次水灾，导致网箱全部损毁，养殖的约三千斤鱼全部被冲走。 受灾现场。 受灾现场。 受灾现场。 9月20日，农业部长江办（农业部长江流域渔政监督管理办公室）相关负责人告诉澎湃新闻，因清江（长江支流）梯级水电站泄洪，湖北省长阳、宜都地区养殖网箱中近万吨外来鲟鱼、杂交鲟鱼逃逸，这些鲟鱼目前已经扩散到长江中下游干流中，“洞庭湖、鄱阳湖，哪儿哪儿都是。扩散范围很大，可能对长江水生生物和生态造成灾难性的影响。该负责人表示，农业部长江办已组织多位水生生物专家，对清江鲟鱼逃逸事件展开调查和生态影响评估。（稿件来源：海外网）
7月19日，受强降雨影响，隔河岩水电站大坝18年来首次泄洪。当日晚上，来势凶猛的洪峰一路横扫河中养殖的数百口网箱。
7月20日凌晨1：50分，救援队接到防汛指挥部命令，隔河岩库区将启动新一轮泄洪方案，随时将泄洪量加大到7000立方米每秒以上至10000立方米每秒的泄洪量，要求所有应急救援船舶就近停航避险待命。大量网箱从清江支汊漂来。
此次水灾导致高坝洲库区网箱损失数亿元，80后张会云所在的白鸭垴村是此次重灾区之一。她家共有网箱14个，此次水灾，导致网箱全部损毁，养殖的约三千斤鱼全部被冲走。她说：“鱼肯定是养不好了，我准备转型发展种植业，把家里几亩农田改种柠檬。”
农业部长江办专家组前期调查报告显示，受7月19日洪水冲击，湖北长阳、宜都地区总重量约0.98万吨的养殖鲟鱼或死亡、或大量逃逸。
7月20日起，长江干流宜昌段以下渔政部门陆续接到来自渔民的外来鲟鱼捕捞记录。7月26日-8月2日，仅在洪湖螺山、嘉鱼等地就有100余尾外来鲟鱼被捕捞到。
参与该调查的中国水产科学研究院长江水产研究所研究员、农业部淡水生物多样性保护重点实验室主任危起伟告诉澎湃新闻，这些逃逸的外来鲟鱼、杂交鲟鱼的数量之大，可能超过长江中下游干流鱼类现存生物量总和，也远远超过了中华鲟的野生种群数量。“这些外来鲟鱼可能与中华鲟等杂交，造成纯种中华鲟难觅。”危起伟说。这是濒临灭绝的中华鲟面临的新威胁。
