The goal of the project is to investigate how we can combine acoustic observations with advanced behavioural models. By simulating the acoustic signal from the behavioural models will we investigate how the acoustic signal is affected by changes in behaviour, and whether it is possible to reconstruct the behaviour through the acoustic signal. In the cases that are possible, acoustic observations can be used to validate the theoretical models, while at the same time (in situ) correction factors may be established.
When observing fish densities using acoustics, may changes in fish behaviour cause changes in observed abundance, without the number of fish being altered. We are trying to estimate and compensate for this effect. At the same time, this change contains information about the fish behaviour, which is relevant for researchers focusing on collective behaviour.
