Fish Tagging

A large number of scientific projects investigating migration behaviour of fishes are carried out in Germany and the neighbouring countries.

At these projects fish are being marked in many different ways. The techniques in use will be presented in this chapter.


Did you catch or find a fish that is equipped with anything similar as shown below?

As an example some kinds of markings that are applied to different fish species are shown here at a European Sturgeon (Acipenser sturio).
