Shark fishing is alive and well, but the fishermen who do it are increasingly prioritizing conservation. And, an unknown ant was spotted in Manhattan in 2011, and it quickly spread through New York City. We now know what it is.
Fishing For—And Saving—Sharks off the Jersey Shore
At an undisclosed beach at 5:30 p.m. in New Jersey, shark fisherman AJ Rotondella and two clients wait for beachgoers to leave. Once the beach is empty, Rotondella cuts up some chunks of fish as bait, and casts lines into the water.
“I shark fish, shark fish, shark fish, eat pizza, and shark fish … that’s pretty much it,” Rotondella said. “Waking up in the morning … wide open ocean, anything could be anywhere at any time. And I think that’s fascinating. No matter how long you’ve done this, you’ve never seen it all.”
He has always loved fishing, and got into shark fishing 13 years ago, when his brother told him they could catch sharks from the beach. They caught two on their first day and could not catch another shark for the rest of the year.
“That really got me interested because I knew it was possible, but I couldn’t do it again,” he said. “I … absolutely obsessed over this.”
But Rotondella had a steep learning curve ahead of him. By trial and error, sometimes staying on a beach for multiple days, he learned how to read the tides, water temperatures, currents, and even phases of the moon to figure out how to track the sharks.

Scientists Identify The ‘ManhattAnt’ Spreading Across NYC
New York City is home to more than 8 million people. But there’s another massive population below their feet: ants.
In 2011, when surveying ant populations on Broadway and Times Square, researchers got quite a surprise: an unidentified species of ant, which was soon dubbed the “ManhattAnt.” Since then, it has become the second-most populous ant species in New York City.
Earlier this year, the first study on this unidentified species was released. It concluded that this species, Lasius emarginatus, likely hitchhiked from Europe to the US. Though their populations have grown tremendously, it’s unclear how the ants are interacting with New York’s native ants.
Joining guest host Sophie Bushwick to discuss this ant species is Dr. Clint Penick, assistant professor of insect ecology at Auburn University in Auburn, Alabama.
