More than 80,000 animals were caught in a catching trial of American crayfish in Krimpenerwaard, but the trial turned out to be unsuccessful. That is what the Water Board of Schieland and the Krimpenerwaard says to on Wednesday after reporting from Broadcasting West. A national approach is needed to solve the lobster problem.

80,000 lobsters seems like a lot, but there aren’t enough and they weren’t caught until they had grown and reproduced. The caught lobsters are mainly used for research and go to restaurants, which process them in their food.

The research is now entering a second phase, in which the animals will be examined in several areas, says Paula Korteweg of the Schieland and Krimpenerwaard Water Board (HHSK). During the trials, further research will be done into the effect of catching lobsters and how much money and people are needed for catching.

National approach needed to solve the problem

A national approach is needed to end the plague, as happened with the muskrats, says Korteweg. The capture tests and studies that are now being done are a preparation for this.

Korteweg explains that such an approach is difficult, because the law does not allow free fishing for the lobsters. Ultimately, it is up to the national government to make it possible for the crayfish to be culled.

American crayfish have been a pest for years. The animal was introduced to the Netherlands around 1985. At first it was not noticeable, but when the animals started to reproduce vigorously, the problems started. They disrupt the ecosystems in different areas, eat all kinds of animals, insects and plants and dig holes and corridors. This makes banks unstable, which affects farmers.
