Young bull sharks find NC sounds inviting

— While seven people have been bitten by sharks off the North Carolina coast in the past month, an expert says people are increasingly likely to encounter a shark in the state's sounds.

Between 1969 and 2011, only nine juvenile bull sharks were found in Pamlico Sound, but researchers have documented 50 young bull sharks in the sound in the last four years alone.

"The main thing that's changed is the temperature's gotten hotter," said Chuck Bangley, a researcher at East Carolina University.

In the last decade, Bangley said, water temperatures in Pamlico Sound have increased about 4 degrees Fahrenheit.

Researchers don't have an explanation for the temperature increase, but they're seeing the effects.

"If the water gets in the 75-degree or higher range for a lot of May, you'll begin to see a lot of juvenile bull sharks show up in the area," he said.

The young sharks will leave in the fall for warmer waters then return again next year, he said.

While people enjoy the sound for the relatively calm waters, young sharks use it as shelter from larger predators, Bangley said.

"Large sharks will come into the sound, but for the most part, what you're looking at are 5, 4 feet or less," he said. "They're also not species that typically eat large prey."

Bull sharks are blamed for biting more people than any other species of shark. Known for their aggressive nature, their bite is particularly strong.

"Even those accidental bites, because we're talking about a big, powerful animal, can do a lot of damage," he said.

Researchers are still collecting data on the number of bull sharks in Pamlico Sound, but Bangley said their presence indicates the shark population, which had been on the decline, is reversing course. It also is a sign of a healthy ecosystem in the sound, he said.

"The fact that bull sharks are pupping in North Carolina suggests the waters are clean, there's an abundant food source for them and there's plenty of habitat," he said.

    WRAL-Please read the study and don't take things out of context. There were more than 9 bull sharks in Pamlico Sound in the past 40+ yrs and many large ones at that. They only caught that many during sampling. Please WRAL have some journalist integrity and do proper reporting. But I know, if it bleeds it leads.

    My hometown was featured on "River Monsters" for the same thing: Bull Sharks raising their young in the brackish waters of the Indian River Lagoon. This species has the most testosterone of any species of animal and is extremely aggressive when it decides something is prey.

    When I was little kid, we were not allowed in the Indian River, even in water merely halfway up our calves, because of the potential that a Bull Shark might be lurking nearby. That my parents considered them a greater risk than Florida's ubiquitous alligators should tell you something.

    More so than anything, shark conservation actions of the 2005-2012 time period have yielded a rise in the total number of sharks in the near shore waters. More Sharks= more potential for shark/human interaction.

    without fishing, many of these communities would not even exist. Fishing not only brings in revenue dollars but a very large proportion of tourist come to the coast for the sole purpose of fishing which supports the local economies.

    What evidence do you have of this? Fishing licenses are at the state level, not local.

    and the chumming of waters because local communities can charge large fees for fishing licenses do not help
