We are extremely proud to introduce you to Dr. Christina Pasparakis! On August 10th, Dr. Pasparakis successfully defended her Ph.D. dissertation entitled “Effects of Temperature, Ultraviolet Radiation and Crude Oil Exposure on Early – Life Staged Mahi – Mahi (Coryphaena hippurus). It has been an honor to work with her and be a part of … Continued
Original story by Emily Frost of Smithsonian Ocean Portal For a month during the summer of 2016, Lela Schlenker spent several hours in the dead of night watching mahi-mahi and waiting to catch them in the act. The colorful and large fish spawn in the cloak of darkness, and she needed to say with certainty … Continued
Story by Diana Udel MIAMI– University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science Professor Martin Grosell received the Award of Excellence in fish physiology from the American Fisheries Society. The award was presented to Grosell during the 13th International Congress on the Biology of Fish for his outstanding career contributions to the … Continued
From Story by Danielle Hall from Smithsonian Ocean Under the lens of a microscope—in a shallow, glass well—spindly orbs pulse at regular intervals. They are, in fact, heart cells from a mahi-mahi fish, specially prepared with the precision and care required of a surgeon. A quick succession of shocks administered by fish scientist … Continued
We are extremely proud and happy to introduce you to Dr. Jason Magnuson! It has been an honor to work with him and be a part of his Ph.D journey through RECOVER at the University of North Texas. We are excited to see what the future holds for him as he continues on into his … Continued
Over the course of the past two months, we have released two videos – Mini Mahi Tags Part 1 and Tunnels and Tags: Mini Mahi Tags Part 2. These two videos are part of our three part video series featuring one of the innovative research projects being conducted by RECOVER team member, CJ McGuigan. At … Continued
Dr. Aaron Roberts, a co – principal investigator with the RECOVER consortium and based out of the University of North Texas, brought larval fish and oil spill science into the classroom at Newton Rayzor Elementary. During this 2 – week outreach program, Dr. Roberts went into the first grade classroom of Mrs. McGary and aided … Continued
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
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
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
