每年有超过1000万条c 35鱼类在位于埃姆斯河口的埃姆斯发电站的EC 20机组受到冲击。最丰富的是：鲱鱼鲱鱼，虾虎鱼（虾虎鱼科）。Nilsson's pipfish Sygnathus rostellatus，三刺鱼Gasterosteus aculeatus和Sprattus sprattus。撞击显示出季节性的模式，反映了在河口鱼类的存在。结果进行了比较，与其他冲击的研究在发电站在比利时和荷兰河口。1995年，冷却水入口从海岸线移至潮汐通道边缘离海岸300米处。通过比较进水管搬迁前（1992-1993年）和搬迁后（1996-1997年）冷却水和河口中鱼类密度的比值，讨论了这种搬迁对鱼类撞击水平的影响。
On an annual basis >10 million individuals of c 35 fish species are impinged at the EC20 unit of the Eems power station located on the Ems Estuary. The most abundant are: herring Clupea harengus, gobies (Gobiidae). Nilsson's pipefish Sygnathus rostellatus, three-spined stickleback Gasterosteus aculeatus and sprat Sprattus sprattus. The impingement shows a seasonal pattern which reflects the presence of the fishes in the estuary. The results are compared with other impingement studies at power stations on the Belgian and Dutch estuaries. In 1995, the cooling water entrance was displaced from the shoreline to 300 m off the coast at the edge of the tidal channel. The effect of this relocation on the level of fish impingement, determined by comparing the ratio of fish density in the cooling water and in the estuary before (1992-1993) and after (1996-1997) the relocation of the intake canal is discussed.
