How Grad Student Schlenker “Sniffs Out” Oil’s Effects on Mahi-Mahi

Story by Maggie Dannreuther Laboratory studies at the University of Miami suggest that exposure to Deepwater Horizon oil may have negatively affected heart function in mahi-mahi, reducing their ability to swim efficiently. Lela Schlenker is expanding that research to investigate if and how oil exposure alters the way mahi-mahi migrate and respond to predators and … Continued

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 … Continued

Study Finds Oil, UV Radiation, and Temperature Affect Mahi Survival Processes

Story by Maggie Dannreuther Researchers conducted exposure experiments with mahi-mahi embryos using oil, ultraviolet (UV) radiation, and temperature to determine how multiple stressors affect their survival. Compared to controls, exposed embryos floating near the ocean’s surface started to sink sooner and at faster rates, which intensified at higher temperatures. The embryos also exhibited higher oxygen … Continued
