Amberjack Tagging

Acoustic tagging and tracking with an extensive underwater acoustic receiver array system is being used to examine greater amberjack spawning site fidelity and movement ecology in the Florida Keys by Marine Fish Biology. To address knowledge gaps and better understand why the Gulf of Mexico stock has failed to rebuild according to rebuilding timelines established in the Fishery Management Plan, acoustic tagging of this species on the seamounts, popular offshore fishing areas in the Florida Key, began in December 2016. In this photo, FWRI biologists insert an acoustic tag into the abdominal cavity of an amberjack (left) and take a catheter biopsy sample (right) to determine gender and spawning status. The sonic tags will transmit data for up to 10 years, allowing researchers to track individuals as they make migratory movements to and from spawning areas.
