Gray Triggerfish Balistes capriscus is an economically valued reef fish species, managed by the South Atlantic Fishery Management Council as part of the snapper-grouper complex fishery. Over the past twenty years, commercial landings cumulatively approached over 7,000,000 lbs. in U.S. Atlantic waters. Despite the economic importance of this species, no peer-reviewed published information exists concerning age, growth, and reproduction in U.S. Atlantic waters. Fishery-independent samples were utilized to assess life history parameters of the Gray Triggerfish population off the southeastern U.S. Atlantic coast during 1991-2012. Specifically, temporal variation in life history parameters was determined by comparing parameters between 1994-1997 and 2009-2012. Specimens were assigned ages from increment counts on the first dorsal spine. Sex and reproductive state were determined from histological section of the gonad. Males were significantly larger than females (337 and 304 mm FL, respectively). Mean ages were significantly different between males and females (3.7 years and 3.4 years, respectively). Female spawning season occurred from April to September with a peak spawning period from May to August. Mean lengths of males and females significantly increased between the two time periods. These results provide essential life history information for any future stock assessments and have the potential to affect future management decisions of the Gray Triggerfish population off the southeastern U.S. Atlantic coast.
