    The article is concerned with discussion of the Analysis of anomalous CPUE data from data-poor exploratory fisheries (WG-FSA-12/07). Key points of the paper were presented and discussed during the Workshop for the Analysis of the Anomalous High CPUE by Korean Vessels in the CCAMLR Area (2013,April 29th - May 1st, Busan, Korea). This paper attempts to explain possible reasons of anomalous 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 conclusion that a discussion on anomalous high CPUE in the specified areas using available data and techniques of their processing is bleak.
