"This report presents estimates of annual catches of tuna, billfish, and other highly migratory species (HMS), and vessel participation during 2011–2015 for fisheries of the United States and its Participating Territories operating in the western and central Pacific Ocean (WCPO). All statistics for 2015 are provisional. Statistics for 2014 have been updated from those reported provisionally in the submission of 2013-2014 U.S. fishery statistics for the western and central Pacific Ocean (NOAA, NMFS 2015). Statistics for 2011–2013 have not been updated. For the purposes of this report, the WCPO is defined as the Western and Central Pacific Fisheries Commission (WCPFC) Statistical Area. For the most part, U.S. estimates of catch by weight are estimates of retained catches due to lack of data on weights of discarded fish"--Page 2 [doi:10.7289/V5/DR-16-038 (http://dx.doi.org/10.7289/V5/DR-16-038)]
