Abstract: The understanding of fish-flow interactions is of primary importance to the design of interventions aimed at restoring freshwater fish habitats. We propose a dual plane particle image velocimetry (PIV) based method for indirect assessment of instantaneous drag forces experienced by live fish. Preliminary experiments have been carried out on fish models combining drag measurements with acoustic velocimetry measurements to explore the performance of developed instrumentation and also optimise upcoming PIV experiments.
