Organismal Biology research activity focuses on effects of environmental factors on fish swimming withis the constext of energetics, predator-prey interactions, intra-specific behaviour and habitat selection. A lot of information on fish locomotion has been collected, focusing on fundamental questions such as the mechanisms of locomotion. However, small attention has been given to the behavioural and ecological context within fish movements. IMC activity is taking into account how swimming performance is modulated by:

The research includes both laboratory and field investigations. A recent development is the measurements of differential pressure at the tail level (as an indicator of tail beat frequency and amplitude, hence swimming velocity) and at the opercular level (as an indicator of ventilation frequency, hence oxygen consumption). Laboratory experiments allow a calibration of the methodology. In situ experiments are done by transmitting data via radio.

Laboratory work includes respirometry, high speed video, special tanks for behavioural experiments, software for on-line and off-line analysis of animal movements and kinematics .
