Monitoring the Migratory Behavior of Fish

The migratory behavior of fish is a key component of their life history and as such crucial for the ecological management of our watercourses. In turn, this means that related management measures can only be optimized through an in-depth understanding of the migratory behavior.

An efficient ecological management of our water courses requires a good understanding of the migratory behavior of local fish populations. With this knowledge, the actual effectiveness of potential management scenarios can be evaluated at an early planning stage, i.e. before their implementation. Examples for this are:

• Where should potential spawning sites be built for a target species and how should they be made attractive?
• How does habitat use differ between species and is a fish pass necessary?
• A weir must be equipped with a fish pass, but is it otherwise really impassable?
• What are the survival rates of highly migratory fish in our watercourses and what are the influences of predation, industrial water intakes, etc.?

A particularly suitable method for answering these and many other questions is fish telemetry, one of our core competences.

Our Profish scientists are actively involved in the development, efficancy analysis and assessment of management actions, underlining our commitment towards an ecological continuity of our rivers and streams.
