Longbill spearfish might be the least encountered of the bunch. They weren’t even formally described as a valid species until 1963, 171 years after the first billfish species (sailfish) was described. They are thought to inhabit the Atlantic Ocean only, with higher densities in the western than eastern side of the pond. However, we have little in the way of good fisheries data for this species. Until fairly recently, ICCAT lumped catch data for longbill spearfish and sailfish into a single stock assessment. In 2009, the combined catch data was split with sailfish getting periodic assessments, with the most recent taking place this year. However, no assessments have been conducted on longbill spearfish, so as of right now, the status of their stocks remains largely unknown.
