Shark Tagging with Gang Alternative


By Jake Jerome, RJD Graduate Student and Intern On Wednesday, July 16, the RJD crew set out to waters around Miami’s historic stiltsville just off Key Biscayne in hopes to tag and release sharks for our ongoing research. We were joined by kids from the Gang Alternative program and a few citizen scientists. Many had never been on a boat before and were excited to see what was in store for the day. After a discussion about sharks, led by our trip leader Pat, we set off for our fishing waters. Once we arrived, we deployed our first set of … Continue reading

Shark Tagging with Rutgers

By Laura Vander Meiden, RJD Intern Our chartered boat, the Diver’s Paradise, headed out under sunny skies early Friday, July 11th with a volunteer crew of Rutgers graduate students. There was a slight swell to the ocean, but given the stormy weather earlier in the week we were happy to be out on the water no matter the conditions. The boat was headed to a tagging location nicknamed Sandbar Palace by one of the RJ Dunlap interns. Located within sight of Miami Beach, this spot acquired the name due to a large number of sandbar sharks caught there on a … Continue reading

It was exciting to hear that many of them were not from coastal states and were getting the chance to see sharks … Continue reading

Bioactive Compounds Derived from Marine Algal Species

D. Salina

By Kyra Hartog, RJD Intern 1. Introduction Marine algal species produce a variety of compounds that are ultimately beneficial to human health. These compounds are often produced as secondary metabolites [1], meaning they are not essential to the algal species’ survival but benefit the organism in some way. These compounds include, but are not limited to, polyunsaturated fatty acids and carotenoids, as well as compounds with antibiotic and antifungal activity. Those compounds with antibiotic and antifungal activity are being investigated for use as components in anti-fouling paints for maritime industries around the world [1]. Polyunsaturated fatty acids are being studied … Continue reading

Shark Tagging with the University of Miami Alumni Association


By James Keegan, RJD Intern Saturday’s trip looked like it would be a gloomy one with overcast and rain. I was excited for the catered trip, but I left for Crandon Marina with a sense of dread. The prospect of tagging sharks in choppy waters and cold rain did not thrill me. However, once the RJD team loaded the Diver’s Paradise, the skies cleared up a little. After Captain Eric and Neil went over safety and gear deployment, members of the Alumni Association and the RJD team introduced themselves. As we left for Soldier Key, the skies completely cleared, and … Continue reading
