Abstract:
This dataset reports mahi-mahi (Coryphaena hippurus) tagging data derived from a research cruise aboard the R/V F.G. Walton Smith WS19159 from 2019-06-09 to 2019-06-21 in the Gulf of Mexico as part of a mission to satellite tag adult control and oil exposed mahi-mahi. The dataset includes angling time, fish condition, fork length, sex, tagging information and fate of all mahi-mahi tagged. Mahi-mahi were captured using hook and line angling from the research vessel (R/V Walton Smith), or the fishing vessel (F/V Yellowfin). Some additional mahi-mahi caught from a fishing vessel were transferred to R/V Walton Smith and were tagged, recovered, and released from there. The R/V F.G. Walton Smith cruise WS19159 was led by chief scientist Lela Schlenker with the objective of tagging mahi-mahi with pop-up satellite archival tags.

Methods:
Mahi-mahi were captured using hook and line angling from the F/V Yellowfin, or the R/V Walton Smith, were measured for fork-length, sampled for a fin clip, tagged with a pop-up satellite archival tag, were placed in a 5,000 L oil or control tanks for 10-20 hours, and were released. Fish that were in poor condition or died prior to release were not released.
