DEC UPDATE ON STATUS OF VHS IN NEW YORK STATE WATERS
New Federal Order Issued That Restricts Interstate Transport of Live Fish
The New York State Department of Environmental Conservation
(DEC) is issuing this update on the presence of Viral Hemorrhagic Septecemia
(VHS) Virus in New York State waters and a new federal order that restricts
the interstate transport of certain live fish. The virus is a pathogen of
fish and does not pose any threat to public health. It was first confirmed
in Lake Ontario and the St. Lawrence River, and has now also been confirmed
in Lake Erie and Conesus Lake.
VHS is a fish disease that causes the hemorrhaging of the fish’s tissues,
including internal organs. Often, fish do not exhibit any external signs of
having the disease. The disease affects all sizes of fish and not all
infected fish develop the disease, but can continue to carry it and spread
it to others. There is no known cure for VHS. The impact of this particular
strain of VHS on fish populations is uncertain. It has caused fish
mortalities ranging from a few fish impacted to thousands of fish impacted.
While VHS is relatively common in continental Europe and Japan, where it
affects both freshwater and marine fish, prior to 2003 the disease was
limited in North America to marine species in the Atlantic and Pacific
Oceans. In 2005, a die-off of freshwater drum and round goby in Lake
Ontario’s Bay of Quinte (Ontario, Canada) and muskellunge in the Michigan
waters of Lake St. Clair was attributed to a new strain of VHS. This is the
same strain found in the infected fish in New York waters.
VHS was first confirmed in New York waters in May 2006 when it was linked to
the death of round gobies and muskellunge in Lake Ontario and the St.
Lawrence River. More recently, VHS caused the death of walleye in Conesus
Lake. The virus has now been confirmed in round goby, burbot, smallmouth
bass, muskellunge, pumpkinseed, rock bass, bluntnose minnow, emerald shiner
and walleye in infected waters in New York State. To date, the virus has not
been confirmed in trout and salmon from these waters and it is unknown
whether this strain of VHS will impact these species.
DEC, in cooperation with the College of Veterinary Medicine at Cornell
University, is sampling a number of waters across the State including all
waters used as sources of brood stock for DEC hatchery activities to help
determine how far the disease has spread in New York. DEC is also exploring
options for actions that could be taken to prevent the further spread of the
disease in the State.
Due to the potential adverse effects of this disease on fish populations and
the desire to prevent or delay its spread to other states, the USDA Animal
and Plant Health Inspection Service (APHIS) issued a Federal Order on
October 24, 2006, that prohibits the importation of certain species of live
fish from Ontario and Quebec and interstate movement of the same species
from eight states bordering the Great Lakes, effective immediately. The
states included are Illinois, Indiana, Michigan, Minnesota, New York, Ohio,
Pennsylvania and Wisconsin.
Fish species included in the federal prohibition are: Atlantic cod, black
crappie, bluegill, bluntnose minnow, brown bullhead, brown trout, burbot,
channel catfish, chinook salmon, coho salmon, chum salmon, emerald shiner,
freshwater drum, gizzard shad, grayling, haddock, herring, Japanese
flounder, largemouth bass, muskellunge, Pacific cod, northern pike, pink
salmon, pumpkinseed, rainbow trout, redhorse sucker, rock bass, rockling,
round goby, smallmouth bass, sprat, turbot, walleye, white bass, white
perch, whitefish and yellow perch. Additional fish will be added to the
order as they are confirmed to be carriers of this disease. Additional
information on the Federal Order can be found on the APHIS website
www.aphis.usda.gov/vs/aqua/ .
VHS can be spread from waterbody to waterbody through a variety of means,
not all of them known at this point. One known mechanism is through the
movement of fish, including bait fish. To reduce the likelihood of spreading
VHS in New York State, DEC encourages anglers and boaters to abide by the
following guidelines:
* Remove all mud, aquatic plants and animals from all gear, boats, motors
and trailers before leaving a body of water;
* Drain your live well, bilge and bait tanks before leaving the fishing or
boating water. Anglers or boaters using infected waters should disinfect
their live wells and bait wells with a 10 percent chlorine/water solution.
Rinse well to remove all residual chlorine;
* Do not transport fish from one body of water to another. Note that this
practice is illegal without a DEC fish stocking permit;
* Only use bait fish in the waterbody it was taken from. Bait purchased
commercially should not be released into any body of water; and
* Do not dispose of fish carcasses or by-products in any body of water.
The public is advised to contact their nearest DEC regional office if they
witness a large number of dead or dying fish (usually 100 or more).
Questions about VHS and potential DEC actions to prevent its spread can be
e-mailed to fwfish@gw.dec.state.ny.us or by calling 518-402-8896. The public
is also advised to regularly check the Department website
