Model estimates of pre- and post- abundances of the cetaceans in the Antarctic Ecosystem
IWC document SC/68D/EM/WP04 provided a list of pre-exploitation estimates of abundance for the Antarctic blue, fin, humpback, minke, southern right, sei and Bryde’s whales in the region(s) south of 60°S, based on modelling studies. The authors were tasked with compiling this list as part of the inte...
