DEC UPDATE ON STATUS OF VHS IN NEW \nYORK STATE WATERS New Federal Order Issued That Restricts Interstate \nTransport of Live Fish<\/span><\/b><\/p>\n
The New York State Department of \nEnvironmental Conservation (DEC) is issuing this update on the presence \nof Viral Hemorrhagic Septecemia (VHS) Virus in New York State waters and \na new federal order that restricts the interstate transport of certain \nlive fish. The virus is a pathogen of fish and does not pose any threat \nto public health. It was first confirmed in Lake Ontario and the St. \nLawrence River, and has now also been confirmed in Lake Erie and Conesus \nLake.<\/p>\n
VHS is a fish disease that causes the \nhemorrhaging of the fish’s tissues, including internal organs. Often, \nfish do not exhibit any external signs of having the disease. The \ndisease affects all sizes of fish and not all infected fish develop the \ndisease, but can continue to carry it and spread it to others. There is \nno known cure for VHS. The impact of this particular strain of VHS on \nfish populations is uncertain. It has caused fish mortalities ranging \nfrom a few fish impacted to thousands of fish impacted.<\/p>\n
While VHS is relatively common in \ncontinental Europe and Japan, where it affects both freshwater and \nmarine fish, prior to 2003 the disease was limited in North America to \nmarine species in the Atlantic and Pacific Oceans. In 2005, a die-off of \nfreshwater drum and round goby in Lake Ontario’s Bay of Quinte (Ontario, \nCanada) and muskellunge in the Michigan waters of Lake St. Clair was \nattributed to a new strain of VHS. This is the same strain found in the \ninfected fish in New York waters.<\/p>\n
VHS was first confirmed in New York \nwaters in May 2006 when it was linked to the death of round gobies and \nmuskellunge in Lake Ontario and the St. Lawrence River. More recently, \nVHS caused the death of walleye in Conesus Lake. The virus has now been \nconfirmed in round goby, burbot, smallmouth bass, muskellunge, \npumpkinseed, rock bass, bluntnose minnow, emerald shiner and walleye in \ninfected waters in New York State. To date, the virus has not been \nconfirmed in trout and salmon from these waters and it is unknown \nwhether this strain of VHS will impact these species.<\/p>\n
DEC, in cooperation with the College of \nVeterinary Medicine at Cornell University, is sampling a number of \nwaters across the State including all waters used as sources of brood \nstock for DEC hatchery activities to help determine how far the disease \nhas spread in New York. DEC is also exploring options for actions that \ncould be taken to prevent the further spread of the disease in the \nState.<\/p>\n
Due to the potential adverse effects of this \ndisease on fish populations and the desire to prevent or delay its \nspread to other states, the USDA Animal and Plant Health Inspection \nService (APHIS) issued a Federal Order on October 24, 2006, that \nprohibits the importation of certain species of live fish from Ontario \nand Quebec and interstate movement of the same species from eight states \nbordering the Great Lakes, effective immediately. The states included \nare Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania \nand Wisconsin.<\/p>\n
Fish species included in the federal \nprohibition are: Atlantic cod, black crappie, bluegill, bluntnose \nminnow, brown bullhead, brown trout, burbot, channel catfish, chinook \nsalmon, coho salmon, chum salmon, emerald shiner, freshwater drum, \ngizzard shad, grayling, haddock, herring, Japanese flounder, largemouth \nbass, muskellunge, Pacific cod, northern pike, pink salmon, pumpkinseed, \nrainbow trout, redhorse sucker, rock bass, rockling, round goby, \nsmallmouth bass, sprat, turbot, walleye, white bass, white perch, \nwhitefish and yellow perch. Additional fish will be added to the order \nas they are confirmed to be carriers of this disease. Additional \ninformation on the Federal Order can be found on the APHIS website www.aphis.usda.gov\/vs\/aqua\/<\/a><\/p>\n
Syracuse \nPost Standard<\/b><\/span>Lake diseases linked to invasive species Sunday, \nNovember 05, 2006 \n<\/span><\/b>By Delen Goldberg \nStaff writer<\/p>\n
Paralyzed water birds drown and float dead to shore. Virus-infected \nfish bleed out of their eyes. Invasive mussels and fish interact to spread \ntoxic bacteria.<\/p>\n
It’s not a worst case-scenario. It’s what’s happening now on Lake \nOntario, and scientists say invasive species and diseases are to blame.<\/p>\n
In recent weeks, a toxic form of botulism has killed more than 500 \ncommon loons on the lake. A virus that causes uncontrolled bleeding has \ninfected thousands of fish, killing hundreds and prompting federal \nofficials to ban the transport of more than three dozen species.<\/p>\n
“It’s a horrible feeling, walking around the beach and seeing a \nbunch of corpses,” said Jack Manno, executive director of the Great \nLakes Research Consortium at the State University College of Environmental \nScience and Forestry. “People who have a sense that something is \nwrong are right.”<\/p>\n
Botulism spores have long been found in the sediment lining the bottom \nof Lake Ontario, but until quagga mussels arrived in the early 1990s, no \ntoxic outbreaks bloomed, according to Helen Domske, a Buffalo-based senior \nextension specialist for New York SeaGrant. Many scientists believe the \noutbreaks began when quagga mussels started interacting with another \ninvasive species: round gobies.<\/p>\n
“You can have quagga mussels, but until you have round gobies, \nit’s no problem,” Domske said. “It’s the two working together \nthat causes these outbreaks.”<\/p>\n
Quagga musselssuck oxygen from Lake Ontario, creating a perfect \nbreeding ground for toxic botulism, Manno said. While feeding, the mussels \nabsorb botulism spores and concentrate them in their systems. Round gobies \nfeed on the mussels, then pass the toxin on to the loons, gulls and \nmergansers that eat them.<\/p>\n
The disease that is killing fish, viral hemorrhagic septicemia, also \nhas no roots in Lake Ontario.<\/p>\n
“We think VHS is an exotic, a recent introduction to the Great \nLakes,” said Gerry Barnhart, director of fish, wildlife and marine \nresources for the state Department of Environmental Conservation. \n“The virus was likely transported in ballast water in vessels coming \nfrom the Atlantic, through the St. Lawrence Seaway into the Great \nLakes.”<\/p>\n
The recent diseaseoutbreaks have the potential to affect almost every \naspect of the lake, including baitfish sales, sport and recreational \nfishing, tourism and property values.<\/p>\n
The U.S. Department of Agriculture recently banned the interstate \ntransport of 37 species of live fish to try to curb the spread of VHS. The \nstate Department of Environmental Conservation this week is discussing \nenacting similar rules, Barnhart said.<\/p>\n
“It’s an economic problem,” said Manno, of the Great Lakes \nResearch Consortium. “Much of the commercial fisheries on the Great \nLakes are baitfish.”<\/p>\n
Anglers, boaters and tourists in 2003 spent $600 million in the regions \nbordering the Great Lakes and Finger Lakes, according to a 2004 SeaGrant \nstudy, the most recent available.<\/p>\n
“All the communitiesalong the lake and at the tributaries rely \nvery heavily on summer tourism for their economic development, whether \nit’s boating, fishing or sailing,” said Christine Gray, director of \nthe Oswego County Department of Promotion and Tourism. “When there’s \na lot of reporting about issues on the lake, it has an impact on whether \npeople will come here. They often won’t.”<\/p>\n
Said Manno: “Who wants to go to the lake and see a bunch of dead \nbirds?”<\/p>\n
Barnhart said VHS could crush sport and recreational fishing if species \nsuch as smallmouth bass and walleye, both popular local game fish infected \nby the disease, start dying off in large numbers.<\/p>\n
It’s too early to tell if that will happen. Since VHS appeared only a \nfew months ago in Lake Ontario, biologists are holding out hope that the \nfish may build a resistance to the disease.<\/p>\n
But with no cures in sight, scientists expect problems to get worse \nbefore they get better – if they ever do. Biologists at the DEC agree that \noutbreaks of botulism, viral hemorrhagic septicemia and other diseases \nlikely will become yearly events on Lake Ontario, as they have on other \nGreat Lakes.<\/p>\n
“Even if it ends during this migration period, we could see it \nagain next year,” DEC spokeswoman Maureen Wren said.<\/p>\n
Like many invasive species, neither quagga mussels nor round gobies \nhave natural predators in Lake Ontario. Scientists’ only hope is to stop \nthe spread of invasive species before they begin to choke and sicken \ninland water bodies, too.<\/p>\n
That, however, takes funding, legislation and international \ncooperation, the experts said.<\/p>\n
“We’re really at the turning point,” Manno said. “We’re \neither going to do it now or we’re going to regret it later.”<\/p>\n
