Back in the day, I worked as an intern at Rhode Island Marine Fisheries, where my job was basically to provide general field work help with whatever survey needed an extra pair of hands (yes, it was an awesome job). One of these was a beach seining survey looking at juvenile fishes using Rhode Island’s coastal salt ponds as nursery habitat. Among the usual silversides, mummichogs, and juvenile flounder, two of the ponds were also home to entire schools of something that I was only familiar with due to having relatives in Virginia: spot. These little Scianids, a member of the same family as Atlantic croaker and red drum, are caught in droves in the waters of Virginia and the Carolinas but traditionally have been rare north of the Chesapeake Bay. They were one of the more common species we caught in these two Rhode Island salt ponds, and occurred so consistently that we could actually observe them growing over the course of the summer. It isn’t unheard of for stray tropical fishes to get swept into Narragansett Bay on Gulf Stream eddies, where they’re either collected by aquarists or die during their first winter. However, these were populations of spot that we were seeing. I don’t know if these fish survived their first winter or have come back since I moved down to North Carolina, but even at the very beginning of my interest in fisheries ecology I knew this was odd.

Today, Pew unleashed a mini-media blitz on the importance of predation in fisheries management. This got my attention because the interaction between marine predators and fisheries is one of my major research interests. They do a great (and slickly-designed) job explaining the basics of why paying attention to predation matters in fisheries management, and bonus … Read More “Predation Matters” »

When you work on the water long enough, you encounter some unique situations. Whether it’s getting stranded during field work, surviving massive seasickness, having your equipment attacked by hostile sea life, or just seeing something unusual, these anecdotes are an important part of what makes marine science fun (sometimes moreso in hindsight). That’s why I’m creating a new category for posts here called “Fish Tales,” where we can share these stories. To start with, here is a literal fishing story.
While I was down in Morehead City for some field work (post on that coming soon), I got the chance to do a little fishing with fellow Southern Fried writers Andrew and Amy and check on potential sites for shark sampling this summer. I’d wanted to test out a new fishing rod set up for sharks and large fish, and had rigged up a wire leader with a size 12/0 circle hook. While casting, it became very clear that I hadn’t properly attached the leader to the swivel when I pulled back an empty swivel where the leader had been. Frustrating, but I’m practically required to lose gear every time I fish, so I rigged up a second wire leader with a J-hook that was on hand.
Circle hooks are used by recreational and commercial hook-and-line fisheries (and many longliners) to reduce hooking mortality in large fishes, sharks, and bycatch animals like sea turtles. The idea is that the hook more or less works by itself without being set like a J-hook. The shape of the hook prevents swallowing and encourages hooking in the corner of the mouth, where it’s less likely to do serious damage.
