Development of a 3D Fish Tracking System and Ethohydraulic Analysis of Trajectories Using 3D HN Simulations

Project members

Abstract

The Department of Hydraulic Engineering and the Institute for Geodesy are developing a 3D fish tracking system, which records the coordinates of the fish’s trajectories in three dimensions. Various flow parameter can be assessed along the fish’s path using a 3D hydrodynamic numerical model. Thus, within the meaning of ethohydraulic analysis, a direct comparison of the swimming paths to hydraulic signatures can be made. In order to use the tracking system in the field, technologies are used, that are even operative in high water turbidity. Therefore, an infrared camera with structured light technology is utilized.

Abstract

In this DBU-sponsored project, the Department of Hydraulic Engineering in cooperation with the Ecohydraulic Engineering Office SJE, the Office for Water Ecology HYDRA and the Centre of Biorobotics at the Tallinn University of Technology are developing a combined measuring and modelling system for the downstream migration of fish. In addition to the development of a fish shaped measuring sensor equipped with an artificial lateral line organ (by TalTech) as well as the research of new ethohydraulic signatures, it is the aim to implement a behavioral matrix into the model system CASiMiR (by SJE) and thus, to enhance the design, evaluation and optimization of facilities for the downstream migration of fish at hydropower plants.
