This project will aim to address a pressing issue related to acoustic telemetry developments and estimating predation rates from marine mammals by generating telemetry data on preys (here the most widely distributed anadromous salmonid species, the brown trout or sea trout, Salmo trutta) and predators (here the most widely distributed pinniped species, the harbour seal, Phoca vitulina) to quantify spatio-temporal interactions and predation rates on prey tagged at different acoustic frequencies; i) well-within the hearing capacity of most marine mammal species at 69 kHz; and ii) outside their hearing capacity at 180 kHz. The project will use a combination of tagging techniques on both trout and seals. (edited)
