Final report
Publication metadata
The main purpose of this study is to provide advice to the Directorate-General for Maritime Affairs and Fisheries (DG MARE) on whether the use of circle hooks per se is effective in reducing mortalities of unwanted species (i.e. species protected and/or subject to release-alive policy), without significantly affecting the catch rates and yields of the targeted species and/or the economic viability of longline fisheries. Other gear configuration modifications, namely bait type and leader material, are also considered. This study concerns the pelagic longline fisheries targeting, in the Atlantic Ocean and adjacent seas (Mediterranean Sea), swordfish, tropical and/or temperate tunas, as well as desirable bycatches of certain species of shark (e.g. blue sharks and shortfin mako) and marlins/sailfishes contributing to the economic viability of the fisheries.
