Modern technology helps to study life in the aquatic environment

Whether it is deer, elephants or lions: if you want to know how they behave, you can easily get an idea. It is relatively easy to notice the animals that live on Earth. However, the situation is completely different with fish in lakes and other bodies of water. “Exactly what fish do throughout the day, how and with whom they interact, and how different individuals react to danger and new situations is completely unknown to most natural bodies and species,” explains Professor Robert Arlinghaus, who is at Humboldt University Berlin. At the Leibniz Institute for Freshwater Ecology and Inland Fisheries it has been dealing with fisheries management issues for a long time. In the specialist journal Science, he and other experts presented a method by which the movements of fish can be accurately reproduced. With its help, it is already possible to gain deeper insights into the behavior of local fish in this country, such as pike and carp. Among the authors of the new publication is fish biologist Thomas Clevoth, a professor from the Bremen University of Applied Sciences.
