There are far more fish from foreign waters in the Wadden Sea than was previously known. According to researchers from the University of Wageningen and the Royal Netherlands Institute for Sea Research, the presence of twaite shad is particularly special.
–
A year ago, several species of fish received transmitters for study, so they could accurately map where they would swim.
–
Fin received that transmitter off the Belgian coast. “Halos twaite was known to migrate in the winter, but no one knew where to go,” said researcher Jena Edwards. Omrop Fryslan. “That it is the Wadden Sea was a big surprise.”
–
The researchers also found that sea bass swim from here to the English and Belgian coasts and that eels from the German upper Vecht also swim to the Wad.
–
All this information is valuable, says Edwin Winter of Wageningen Marine Research at the regional broadcaster: “We see, for example, that some species are dwindling in the Wadden Sea. The cause may lie in the Wageningen Sea itself, but it can also be that are located outside the Wadden Sea. We want to know which buttons we can turn to bring back those populations that use the Wadden Sea. “
