Abstract:

This dataset reports mahi-mahi tagging data derived from a research cruise on board the R/V F.G. Walton Smith cruise WS17177 from 2017-06-26 to 2017-06-28 in the Florida Straits as part of a mission to satellite tag adult control and oil exposed mahi-mahi (Coryphaena hippurus). The dataset includes angling time, fish condition, fork length, sex, tagging information and fate of all mahi-mahi tagged. The R/V F.G. Walton Smith cruise WS17177 was led by Chief Scientist Lela Schlenker with the objective of tagging mahi-mahi with pop-up satellite archival tags.

Purpose:

A mahi-mahi satellite tagging study in the Florida Straits.

Data Parameters and Units:

Station number, latitude (decimal degrees), longitude (decimal degrees), fish number, catch station id (station number), date (mm/dd/yy), time hooked (EST; HH:MM:SS), time boasted (EST; HH:MM:SS), time in tank (EST; HH:MM:SS), angling time (MM:SS), handling time (MM:SS), sex (female or male), fork length (cm), hook location, Samples collected (fin clips were non-lethal, heart samples were lethal), eye condition (1-3, excellent-poor), color (1-3, excellent-poor), activity (1-3, excellent-poor), initial condition score (3-9, excellent-poor), wounds (wounds present on mahi-mahi brought in for sampling), tank number (1-2, both tanks were 5,000 L recover tanks filled with oxygenated seawater), fate (released or died in the recovery tank), tag number, vessel captured (the R/V Walton Smith is the research vessel where fish were tagged, recovered, and released, the F/V Miss Britt was a small fishing vessel that caught additional mahi-mahi and transferred those fish to the R/V Walton Smith), comments, release station id, release notes.

Methods:

Mahi-mahi were captured using hook and line angling from the F/V Miss Britt 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 recovery tank overnight, and were released the following day. Fish that were too small to tag, in poor condition, or died prior to release had their hearts preserved for future analysis.

Instruments:

Hook and line angling
