Tunnels and Tags: Mini Mahi Tags Part 2

Last month, we released Mini Mahi Tags Part 1. This video featured the different methods being used to assess the metabolic cost and behavioral changes in captive mahi that are carrying pop – up satellite archival tags (PSATs). Wildlife Computers, developer of our PSAT tags, designed a scaled down, non – data collecting “mini” tags to be used specifically for this RECOVER research.

Here we present the second installment of our story, Tunnels and Tags: Mini Mahi Tags Part 2

The first part of the experiment, featured in this video, assess’ the metabolic cost, or cost of doing and maintaining activity, of PSAT tags on mahi raise at the University of Miami Experimental Hatchery. These trails, conducted through swim chamber repirometry, collect data on oxygen consumption and swimming ability by slowly increasing the speed within these chambers over time.

This research, led by University of Miami based RECOVER Master’s student CJ McGuigan, is first of its kind and will provide a comprehensive assessment of our PSAT tags and their impact on wild mahi – mahi. Through this research, RECOVER scientists increase their understanding of how crude oil impacts the biology of this economically and ecologically important fish.

This research was made possible by a grant from the Gulf of Mexico Research Initiative (GoMRI) to the RECOVER Consortium.

The Gulf of Mexico Research Initiative (GoMRI) is a 10-year independent research program established to study the effect, and the potential associated impact, of hydrocarbon releases on the environment and public health, as well as to develop improved spill mitigation, oil detection, characterization and remediation technologies. An independent and academic 20-member Research Board makes the funding and research direction decisions to ensure the intellectual quality, effectiveness and academic independence of the GoMRI research. All research data, findings and publications will be made publicly available. The program was established through a $500 million financial commitment from BP.
