Project: Assessing fish passibility using a robotic fish sensor and enhanced digital imaging

Passibility of spawning fish from lowland rivers to tidal estuaries presents a major challenge to the establishement of sustainable fish populations in the Baltic Sea. Although it is well-known that the vast majority of existing fish passes are at best partially functional, there remain few scientifically objective methods to investigate their complex flows. Metrics focusing solely on only the local hydraulic conditions in and around the fish passes are often missing the "big picture." The main goal of this work is to provide a robust methodology which combines both the recent developments in biomimetic sensor technology and hydrodynamic imaging data in order to improve fish passibilty in tributaries to the Baltic Sea. In order to compare functioning and non-functioning passes, the use of a biomimetic fish robot which experiences the flow via a lateral line sensor can greatly improve both the quantity and quality of information gained. Correlating the results of the local flow field measurements and global sensing information with functional and non-functional passes is expected to provide a state-of-the-art analysis of these complex structures in concert with changing environmental conditions.
