Abstract

The crayfish gutter comprises a gutter equipped with sloping edges that is positioned on the sediment. Invasive freshwater crayfish walk into the gutter and are directed to tubes on its sides, from which they exit the gutter and enter an above-water collection container. To investigate whether this also works in a semi- field situation, the set-up was tested at the outdoor test facility De Sinderhoeve. Investigated was how much of the installed crayfish population was captured, with which efficiency crayfish were caught, whether the was a risk of capturing juvenile eel, and which angle and inner cover of the tube would be most effective. With an efficiency of 93%, respectively 73.3 and 75% of the inserted crayfish were caught in a weeks’ time. Juvenile eel was not caught in the crayfish gutter. The crayfish density in the experiments for tube-efficiency was not high enough to stimulate the crayfish to leave the actual gutter.
