第3002期:Data shows decline in migratory fish populations

The Atlantic salmon and the goonch catfish from Nepal are some of the 30 flagship fish species which had been prioritised for global conservation by the UN.大西洋鲑和尼泊尔巨魾均属于被联合国列为全球优先保护对象的 30 种旗舰鱼类。Population data of more than 15,000 species of freshwater migratory fish, which make up half of all fish species, were assessed by a team of international scientists to identify those most at risk and culturally significant.一个国际科学家团队对 15000 种淡水洄游鱼类的种群数据进行了评估，这些鱼类占到了所有鱼类物种的一半，从而判断哪些物种的处境最危险、且具有重要的文化价值。The fish they selected will now be put forward for listing under the International Convention on the Conservation of Migratory Species.这个团队筛选出的物种现在将被提议列入《保护野生动物迁徙物种公约》。
