Twilight at the crayfish station

When other animals go to bed, crayfish and other aquatic animals become really active.
For many, the aquatic habitat with its numerous, often secretive inhabitants is a largely unknown world. Crayfish, for example, are among the oldest creatures on our planet and play an important role as water policemen. But even small organisms such as water fleas, freshwater shrimps, snails or whirlpool worms can provide important information on how healthy a stream or river is. On the excursion to the crayfish station, you will learn more about the diverse life under water. Jeannot Müller, WWF Riverwatcher, has set himself the goal of repopulating suitable bodies of water in the region with crayfish. During breeding, he strives to promote a near-natural ecosystem in the tanks so that the crayfish can get used to the conditions in the stream early on and have to find their own food. As a result, various other animal and plant species can be found in the pools alongside the crayfish. Jeannot Müller provides an insight into the rearing of the decapods and their development. And he uses various examples to show which animals share the aquatic habitat with the crayfish.
