The wahoo, Acanthocybium solandri (Cuvier), is a high trophic level predator in tropical and sub-tropical
marine pelagic waters worldwide. Wahoo are primarily caught as a retained incidental catch in purse
seine and pelagic longline fisheries that target tuna and swordfish. The global commercial catch of wahoo
has increased in the Pacific Ocean from 130 tin 1993 to a peak in recent years of 1339 tin 2006. Wahoo are
also a highly prized sportfish in recreational fisheries, and although catches are poorly understood, they
may be higher than the commercial catch in some regions. Despite their commercial and recreational
importance, little quantitative information exists on their biology and stock structure, particularly in
the Pacific Ocean. This dearth of information may have significant consequences for stock assessments
and management. Suggested research priorities for wahoo in the Pacific Ocean are to: (1) investigate
their biology in the region, particularly age, growth and reproductive parameters, which are essential for
stock assessment; (2) use holistic methods to determine stock structure on a timescale appropriate for
assessment and management; (3) conduct quantitative diet analyses that may contribute to ecosystem
models, and (4) quantify catch from recreational fisheries to include in estimates of total mortality
