In partnership with Casa Vieja Lodge based in Puerto San Jose, Escuintla, Guatemala, the Guy Harvey Foundation, and sponsors of the Dolphinfish Research Program, in mid-January 2023, six popup satellite archival transmitters were deployed on dorado ranging in size from 39" to 43" fork-length. In addition, vessel Release, Spindrift, and Makaira participated to tag and release 20 more dorado with conventional plastic dart tags. This effort marks the beginning of a concerted effort to better understand the movements and life history patterns of dorado off Guatemala and contributes to ongoing research being conducted in Panama, Ecuador, Costa Rica, Mexico, and within the Southern California Bight by the DRP.
