Assessment of the analysis of anomalous CPUE data from data-poor exploratory fisheries
high CPUE for Dissostichus spp. revealed by several vessels in the Subareas 58.4.1, 58.4.2 and 48.6. A ... number of objective and subjective factors, which can have a principal effect on results of the analysis ... of anomalous high CPUE, are described. The opinion has stated that a criterion of anomalous CPUE ... should be specified under condition of CPUE standardization of different types of longlines. There is a ...
