Nurse shark tagging effort in the Dry Tortugas courtship and mating ground from 1993 to 2021.

For each sex, the total number of tags (PIT, Roto tag, and acoustic transmitter) deployed each year, and the cumulative number of deployed tags (in italics) are provided. In addition, Roto and acoustic transmitter tags that were re-deployments (i.e., on animals that had previously been tagged) are provided inside parentheses for the respective year. These re-deployments were not included in the cumulative number of deployed tags. Dashes indicate instances where no sharks were tagged with a tag type deployed in a given year, whereas grey cells indicate years where certain tag types were not yet deployed in this study.
