few if any marine areas left in the world that are not affected by human
pressure. Human activities affecting flads are for example ditching and cutting
forests as well as dredging and construction in the flads. All these activities
affect the water quality in the flads and further the whole ecosystem. Dredging
especially in the mouth area of the flad can have large effects on the water
exchange in the flad and therefore the temperatures. This kind of changes can have
tragic effects on the flads functioning as a reproduction area for perch and
pike as the temperatures plays a huge role for their reproduction.
One of the
main goals in the project is to test restoration methods in flads and restorate
four flads. These restauration activities should result in local improvement of
the reproduction area for the fish.
