These high catch levels quickly decreased as stocks were fished down. For example, a fishery with a hypothetical unfished biomass of 100,000 tonnes will be allowed to be fished down to a biomass of 40,000 tonnes (assuming that this is the biomass that provides for the maximum sustainable yield) over a number of years. The multi-frequency acoustic optical system (AOS) enables scientists to differentiate the types of fish acoustically ‘seen’ during the survey and works on slopes that previously made effective surveying impossible in some areas.
