More than half a million fish die in Neuse River

More than half a million fish were found dead Tuesday morning in the Neuse River between Otter Creek and Carolina
Pines.
They were killed by a lack of oxygen, said Susan Massengale, public information officer for the North Carolina Division
of Water Quality.
Still water tends to separate into layers with different levels of oxygen, she said. The top layers have the most, while the
bottom layer hardly has any.
Sensors have measured particularly low oxygen levels on the bottom layer for the last five days. But Monday at 11 p.m.
oxygen levels dropped rapidly from the surface to the bottom of the river.
Something stirred the river so that the water with low oxygen was spread up to the fish, she said.
"The fish were already stressed from high water temperatures," Massengale said. "Warm water doesn't hold oxygen.
"It was probably wind or currents that came along and stirred the water. It's not likely it was something unnatural like an
egg-beater."
The Neuse River Rapid Response Team is investigating the fish kill. It is sending samples to a lab at North Carolina
State University to see if algae contributed.
Massengale said about 538,000 fish will be seen floating on the river and drifting to the banks on the three-mile stretch
between channel marker 11 and Carolina Pines during the next few days. Species killed include striped mullet, croaker,
flounder, shrimp, blue crab, silverside and spot, all juvenile.
"We don't want people to panic," Massengale said. "We're investigating, but it was most likely a natural occurrence."
The Neuse River Rapid Response Team wants to hear from the public. Anyone who sees anything unusual is asked to
call (888) 764-7661.
