Abstract

Various types of tags are used across a wide range of teleost and elasmobranch species to collect valuable information on life-history, behavior, migration, and habitat utilization. However, a limited number of studies have been conducted to investigate the costs associated with transporting these tags. Young-adult mahi-mahi (25-35 cm fork length) were tagged with miniature pop-up satellite archival tags (PSATs) to assess the impacts of tagging on various movement parameters in a two- part experiment. Using swim tunnel respirometry, this study revealed significant reductions in the critical and optimal swimming speeds of 10% and 24%, respectively (p0.05) between any of the parameters being analyzed. These findings will aid in the interpretation of data collected from wild, adult mahi-mahi tagged with PSAT’s and may inform work on other species.
