Translated from the Dutch ichthyologists of RAVON:

The numbers of river lampreys counted by RAVON this spring during spawning in a tributary of the Meuse river have exceeded all expectations. Per observation, over seventy fish were counted in eleven spawning holes.
Since 2007, volunteers of the RAVON foundation monitor the number of spawning lampreys in a tributary of the Meuse. This year, spawning began about two weeks earlier than in previous years and the number of animals counted was many times higher than in the four years before.
While in 2009 no more than four lampreys per visit across two spawning holes were observed, the maximum number of fish this year is as many as 73 animals. The number of spawning holes (eleven) is more than in previous years (two to six) as well.
