LINCOLN, Neb. (AP) — Nebraska fisheries biologists are investigating the cause of a fish die-off in a central Nebraska reservoir.

The Nebraska Game and Parks Commission said in a news release Thursday that dead carp have been reported at Davis Creek Reservoir south of North Loup.

The commission says a viral infection is the expected cause of the die-off, and samples have been taken to verify the cause.

The reservoir remains open to fishing, and no other species of fish have been impacted. Anglers should expect to see significant numbers of dead and decaying carp at the reservoir, with the possibility of more distressed fish dying in the coming days.
