Bycatch from purse seining and longlining has been the subject of a considerable amount of research. Small-scale tuna fishing and the associated bycatch have received relatively little attention, and no work has been carried out to obtain a global overview. This document summarizes, on a national level, catch information of small-scale tuna fisheries and those small-scale fisheries that catch tuna. It also aims to identify on a regional basis data gaps, major issues and management concerns associated with these fisheries and their bycatch.
