N.C. algal blooms caused by heat are killing fish

EDENTON, N.C.

State health officials have issued a warning that algal blooms in the Chowan River and the Albemarle Sound, caused in part by the hot weather, could contain toxins.

Algae can be beneficial to aquatic wildlife, but hot weather and calm water can combine to create large mats or blooms.

People should avoid swimming or ingesting water where the blooms, described as "smelly pea-green soup," have formed. Tests for toxins are being done on the Anabaena planctonica, a filamentous blue-green algae, according to a release from the North Carolina Department of Environment and Natural Resources.

There have been no reports of human sickness.

Fish kills have been reported in the lower Chowan River, and near the Blounts Bay and Pamlico River areas where lower dissolved oxygen levels have been recorded.
