WARREN, PA-A disease outbreak has prompted the removal of more than
700,000 trout from Pennsylvania's Allegheny National Fish Hatchery, and
officials say many of the fish might need to be destroyed.
U.S. Fish and Wildlife Service officials announced last week that lake
trout and brook trout at the hatchery had tested positive for the
infectious pancreatic necrosis virus, which causes hemorrhaging of
internal organs. The infection is highly contagious in fish and can
cause up to 90 percent mortality in young fish. There's no known cure or
treatment, but the virus doesn't affect humans.
The hatchery is home to 720,000 juvenile lake, brook and rainbow trout
and 2,500 lake trout broodstock. The fish are stocked in lakes Erie and
Ontario and around the Allegheny National Forest. Hatchery staff are
working to remove the fish and disinfect the facility.
