New results from the FishView project

The FishView project develops a bio-inspired sensor mimicking fish lateral line measure lakes, rivers and human-made fish passages similar to fishes. The goal of the project is to make fishes happier!

The FishView sensor and project researchers making measurements at a fish passage
Academy of Finland and EU (Horizon 2020) BONUS program funded the FishView project where researchers from three countries develop a novel underwater sensor and signal processing methods to analyze underwater environment from the "fish view". The sensor structure is inspired by the biological lateral line sensor of fishes that allow them to swim economically, tax and sense other fishes and enemies in their proximity. Lateral line provides a kind of "3D view of flows".

The ultimate goal of the project is to develop a field tool for biologists and hydro engineers to inspect natural and human-made fish passages. Making better fish passages e.g. for hydrodynamic plants we can support Baltic Sea fishes natural behaviour.

The artificial lateral line probe was developed in the Centre of Biorobotics, Tallinn University of Technology, Estonia, the signal processing methods in Department of Signal Processing, Tampere University of Technology, Finland, and laboratory and field measurements made by the SJE Ecohydraulic Engineering company from Germany.

The results of the research has been recently published in scientific journals:
