LINCOLN, Neb.- Near the start of summer the common carp living in both Lake Maloney and Sutherland Reservoir experienced a mass die off causing a fishy smell and much concern.

According to a release from the Nebraska Game and Parks Commission the tests that were sent to Washington State University revealed no explanation for the “mortality” seen in just the common carp.

At least seven different diseases contributed to the death of some of the sampled carp, though the koi herpes virus was not present in any of the samples.

At Sutherland Reservoir nearly about 8,500 common carp were washed ashore and less than 1,000 were seen at Lake Maloney.

For officials to understand the die-offs better more testing may be required.
