The Next Step in Mahi – Mahi Satellite Tagging: Mini Mahi Tags – Part 1

Over the course of the next three months, RECOVER will begin preparing for our 15 day research cruise in the Gulf of Mexico, where we will continue to use PSATs (popup satellite archival tags) on wild mahi – mahi. As in the past, this will allow us to continue recording more data on mahi location, depth, temperature, light levels and acceleration.

As beneficial as these tags are in examining mahi behaviors in the wild, they are not without some limitations.

In Part 1 of a new three part series, we introduce master’s student CJ McGuigan and his research at the UM Experimental Hatchery that will use different methods to assess the metabolic cost and behavioral changes in captive mahi that are carrying satellite tags. Wildlife Computers, developer of our PSAT tags, designed a scaled down, non – data collecting “mini” tags to be used specifically for RECOVER research.



The next two parts of our video series, will highlight the two different experiments that will be used to asses those changes.

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. For more information, visit
