Descriptions of the U.S. Gulf of Mexico Reef Fish Bottom Longline and Vertical Line Fisheries Based on Observer Data. Scott-Denton Marine Fisheries Review, 73(2):1-26, 2011. Paper abstract bibtex In July 2006, a mandatory observer program was implemented to
characterize the commercial reef fish fishery operating in the U.S. Gulf of Mexico.
The primary gear types assessed included
bottom longline and vertical line (bandit
and handline). A total of 73,205 fish (183
taxa) were observed in the longline fishery.
Most (66%) were red grouper, Epinephelus morio, and yellowedge grouper, E.
flavolimbatus. In the vertical line fishery,
89,015 fish (178 taxa) were observed of
which most (60%) were red snapper, Lutjanus campechanus, and vermilion snapper,
Rhomboplites aurorubens. Based on surface observations of discarded under-sized
target and unwanted species, the majority of fish were released alive; minimum
assumed mortality was 23% for the vertical
line and 24% for the bottom longline fish- ery. Of the individuals released alive in the
longline fishery, 42% had visual signs of
barotrauma stress (air bladder expansion/
and or eyes protruding). In the vertical line
fishery, 35% of the fish were released in a
stressed state. Red grouper and red snapper size composition by depth and gear type
were determined. Catch-per-unit-effort for
dominant species in both fisheries, illustrated spatial differences in distribution
between the eastern and western Gulf.
Hot Spot Analyses for red grouper and red
snapper identified areas with significant
clustering of high or low CPUE values.
