Research


The ambition of the PFA is to maintain a sustainable fishery for pelagic fish stocks, both now and in the future. Collaboration with science and research is an important requirement for that ambition. Martin Pastoors is PFA's Chief Science Officer and responsible for the implementation of the PFA research strategy.

PFA in ICES training course on acoustic surveys


19 June 2017

Martin Pastoors participated in the first ICES training course on acoustic surveys (12-16 June 2017) that was lead by Paul Fernandes (University of Aberdeen) and John Horne (University of Washington) and attracted 25 participants from Europe, USA, Canada and Kenia. The course provided a thorough overview from the basic physics of underwater sound all the way up to the calculation of an age composition in an acoustic trawl survey. The overall process of an acoustic survey can be characterized by the following steps: survey planning - calibration - data collection (acoustic data, biological data) - echogram scrutinizing (identification of fish schools and species compositions) - biological data processing - calculation of fish densities on the survey track - interpolation to abundance estimates - splitting by age or maturity. It was very instructive to be guided through this whole process. Some ideas that could be picked up in the research within PFA: annual calibration of acoustic equipment on trawlers, using software for integrating multiple frequencies in one screen and training in acoustics for vessel crew.
