This paper provides abundance estimate for western North Pacific common minke whales (Balaenoptera acutorostrata) based on dedicated sighting surveys conductedã€€inã€€2013,ã€€2015,ã€€2016,ã€€2017ã€€andã€€2018 withã€€IWCã€€oversight. The common minke whale abundances in sub-areas 7, 8, 9, 10E and 11 were estimated by standard methodology following the â€˜Requirements and Guidelines for Conducting Surveys and Analysing Data within the Revised Management Schemeâ€™. These estimates are presented for possible use in conditioning of the current Implementation Review for western North Pacific common minke whale.
