This paper provides abundance estimate for western North Pacific common minke whales (Balaenoptera acutorostrata) based on dedicated sighting surveys conductedÃ£â‚¬â‚¬inÃ£â‚¬â‚¬2013,Ã£â‚¬â‚¬2015,Ã£â‚¬â‚¬2016,Ã£â‚¬â‚¬2017Ã£â‚¬â‚¬andÃ£â‚¬â‚¬2018 withÃ£â‚¬â‚¬IWCÃ£â‚¬â‚¬oversight. The common minke whale abundances in sub-areas 7, 8, 9, 10E and 11 were estimated by standard methodology following the Ã¢â‚¬ËœRequirements and Guidelines for Conducting Surveys and Analysing Data within the Revised Management SchemeÃ¢â‚¬â„¢. These estimates are presented for possible use in conditioning of the current Implementation Review for western North Pacific common minke whale.
