CHARACTERIZATION OF SWORDFISH BUOY GEAR
CATCHES IN THE FLORIDA STRAITS

Swordfish buoy gear (SBG) is a relatively new commercial fishery located off the eastern and
southern coasts of Florida that began in 2002. The area targeted by this fishery, part of the Florida East
Coast statistical area (FEC), has been closed to commercial pelagic longline gear (PLL) since 2001.
Swordfish buoy gear has largely taken the place of PLL as a commercial fishery for swordfish (Xiphias
gladius) within the FEC. Conceptually, SBG is similar to a vertical longline, with free-floating individual
buoys and “high-flyers” connected to approximately 100 meters of monofilament with one or two hooks
constituting one “buoy.” Most vessels currently using this gear are fishing approximately 10 “buoys”
simultaneously. Due to the way each individual “buoy” drifts independently with the current, SBG is
considered to fish more like PLL than the former NMFS classification of the “handgear” gear type. This
study qualitatively compares swordfish catch rates, bycatch rates, and time on hook between
contemporary SBG field data and historical PLL observer data from the FEC. Initial analysis shows
higher CPUE for SBG vs. PLL (92.2 to 31.8 per 1000 hooks), lower bycatch rates (12.2 to 21.6 per 1000
hooks), and lower average time on hook (2:15 to 6:59). Initial conclusions show that SBG is a cleaner
and more efficient commercial fishery for swordfish in this area when compared to PLL.
