The fish population in New Jersey waters is growing more diverse, and a Rutgers University scientist says climate change is driving it… Dr. Ken Able is the director of Rutgers University’s marine field station in Tuckerton, where for 27 years, they’ve been studying the baby fish that come into the Little Egg Inlet. “And we have a distinct trend,” he says. “We have warming water temperatures, and we have fewer northern species and we have more southern species. And there’s good data to support that.”
