Review of fishery monitoring and forecast procedures
Abstract: The Secretariat monitors the catches of all target and by-catch species (or species ... closed 68 fishing areas, and the total catches of Dissostichus in areas closed using the forecast model ... averaged 98.5% of the relevant catch limits. The forecast model relies on the assumption that the fishery ... the prediction. Using this prediction approach assumes that there will be underruns and overruns of ...
