Tagging Bull Sharks in the Neuse River

Meagan Dunphy-Daly is a graduate student at the Duke University Marine Lab studying the effectiveness of marine reserves in protecting apex predators. She also has ongoing research examining bullshark/dolphin interactions in the Neuse River, NC, where she recently caught an 8 foot bullshark.

Well, it’s Shark Week and instead of heading up to the Neuse River to try to track bull sharks, I’m sitting in front of my computer staring at the marine forecast. Right now, we’re under a small craft advisory until tomorrow night and we’re all keeping our eyes on what Tropical Storm Emily is going to do over the weekend. Such is the ever-exciting life of a field biologist. Although there are a fair number of days spent in an office in front of a computer (be it checking the weather, entering data, or hoping that a manuscript will write itself), the days in the field are what make this job so sweet. I’m a graduate student in Dr. Andy Read’s Lab at Duke University and, in addition to my dissertation interest in the effectiveness of marine reserves for apex predators (think sharks, tuna, and billfish), I have the chance to carry out and participate in many other research projects in North Carolina and elsewhere (check out Reny Tyson’s previous posts on our trip to Antarctica). This summer, I’m studying bull shark habitat use in the Neuse River. Andrew joined us for a day of fieldwork last week and, although we didn’t catch a shark on this trip, we caught a big bull shark on the first day of our season the week before.

Ocean of Pseudoscience Linkfest, Round 4 and reader challenges

More people have joined in on the Ocean of Pseudoscience week.

First, Shark Diver from Underwater Thrills throws down with Shark Pseudoscience – Juicing Tweaked Bulls. Something tells me Bull Shark Testosterone isn’t going to make you cool, but let’s see if our readers can come up with an explanation why.

The link leads to this picture of an apparently giant freshwater carp that look suspiciously like a goldfish. Well, what do you think, real or fake?
