Description:The ISC Billfish Working Group (BILLWG), in its 2016-2017 work plan, agreed to update its webpage information (ISC 2016a). To that end, this working paper presents standardized figures of the best available life history information for Pacific species regularly assessed by the group and summary figures of recent stock assessment outcomes for these species (ISC 2014a, 2014b, 2015, 2016b). This document provides such figures for three species: Pacific blue marlin (Makaira nigricans), North Pacific striped marlin (Kajikia audax), and swordfish in the North Pacific (Xiphias gladius). The latter is presented as two separate stocks, the Western and Central North Pacific (WCNP) and Eastern North Pacific (ENP) stocks of swordfish. Where possible, the billfish species' life histories are presented by sex. This working paper provides descriptions of the derivation of each figure with relevant equations and parameter sources.
