Bakal, USFWS Emerging conservation problems require immediate attention. Viral Hemorrhagic               Septicemia, or VHS, is one such issue. This viral fish disease has recently   caused major episodes of fish die offs in the Great Lakes. Scores of game and   non game species died in droves in spring and early summer of 2006 in several   waters in the Great Lakes. Large fish kills were reported in the U.S. and   Canada. To address this issue, the U.S. Fish & Wildlife Service’s Division of the   National Fish Hatchery System convened an international body of fish health and   fishery management experts in August to address VHS. They gathered at the   Service’s Great Lakes-Big Rivers regional office in Minneapolis to share what is   known about this new virus in the Great Lakes, and charted an immediate course   to learn more and direct future fishery management needs and research. A leading expert on VHS in the United States, Jim Winton of the US Geological   Survey, indicated that the VHS virus exists in four strains, with a single,   unique substrain occurring in the Great Lakes. The VHS virus has been known in   Europe, Japan, and the coasts of the U.S. for many years; how it came to occur   in the Great Lakes is not known. Winton speculates that it may have originated   in ballast water from oceangoing ships sailing into the Great Lakes, or that it   may have hitchhiked in shipments of hatchery raised fish. Though the virus’s   origin remains unknown, Winton said that the virus’s lack of genetic diversity   in the Great Lakes indicates that it probably has only recently arrived to Great   Lakes waters. The virus could move through the Great Lakes to new species of fish that so         far have not shown vulnerability to the disease, and it could move to new         waters. The virus will probably persist in low levels and some fish will carry         the virus without disease symptoms, much like a person can carry a cold virus         without actually catching a cold. But those carriers can spread it, which can be         a problem in stemming the spread. Scientists expect the disease to spread in the contiguous Great Lakes and   possibly into tributary streams; more fishkills are to be expected, but it   could be that in time, further outbreaks will be attenuated as surviving fish   exposed to the virus become immune. Further outbreaks of the disease may be less   explosive than that which unfolded in early 2006. Inoculating fish in the wild to prevent the spread of disease is simply   impossible. From this Minneapolis meeting, the attending scientists determined   there is much to be learned about VHS, both from a biological and environmental   standpoint. They also determined that containment in the Great Lakes is   paramount. Fisheries professionals should use Hazard Analysis and Critical   Control Point planning, or HACCP, to prevent the spread of the virus.    HACCP is a   simple and orderly strategic planning tool that helps identify and manage risks   in natural resources management. Recreational boaters and anglers should clean   and disinfect their craft and gear much like they are already encouraged to do   to stop hitchhiking aquatic nuisance species. The full effect of this viral disease remains to be seen. But what is known   is the economic impact from large die-offs of important game fishes like trophy   muskellunge, smallmouth bass, and yellow perch in the Great Lakes region could   be profound. Commercial fisheries are also likely to be harmed. Of the 12 known   species impacted by the disease, only two species were not game fishes. The   affects of VHS to endangered species conservation could be equally profound, all   underscoring the immediacy of this conservation problem.

APHIS Viral Hemorrhagic Septicemia   (VHS) Emergency Order – Impacts on U.S. Fish and Wildlife Service Fisheries   Operations What does the APHIS emergency order state?The U.S. Department of Agriculture’s Animal and Plant   Health Inspection Service (APHIS) issued an emergency order prohibiting the   importation of certain live fish from two Canadian provinces into the U.S. and   the interstate movement of the same species between eight states bordering the   Great Lakes due to outbreaks of viral hemorrhagic septicemia (VHS). VHS does not   pose a risk to people but can be highly destructive to certain species of fish. http://www.aphis.usda.gov/newsroom/content/2006/10/vhsfish.shtml What is VHS?VHS is a destructive viral disease that can cause internal hemorrhaging and   death in fish. The disease does not pose a risk to people, but it has been   detected in a number of fish species previously not known to be susceptible   including baitfish species, Coho salmon and channel catfish. A list of   susceptible fish species can be found at the APHIS web site: http://www.aphis.usda.gov/vs/aqua/pdf/vhs_susceptible_species.pdf Will the APHIS emergency order impact the Service’s ability to meet its         treaty obligations to Native American tribes in the Great Lakes?No. The Service’s stocking of lake trout and other Great Lakes fish species in         accordance with Native American treaties will not be affected by the APHIS         order. The list of VHS susceptible fish species do not include the fish species         stocked under our treaty obligations. How is the Fish and Wildlife Service responding to APHIS emergency order?The Fish and Wildlife Service has processes in place to insure that its fish   management programs will not contribute to VHS infections in managed   populations. The Fish and Wildlife Service will have representatives on the   stakeholder team that will assist APHIS in developing an interim rule on VHS   susceptible fish stocks. The Fish and Wildlife Service will also assist the   states and APHIS with surveillance through the National Wild Fish Health Survey. Will the Service’s sea lamprey control efforts be affected by the APHIS   emergency order?No. One key element of the sea lamprey control program, which the Service   conducts as an agent of the Great Lakes Fisheries Commission, is the release of   sterilized male lamprey into the Saint Mary's River in Michigan. Since sea   lamprey are not on the list of VHS susceptible species, this rule does not   affect the Sea Lamprey Control program. The Service’s sterile male lamprey   program has reduced the total lamprey population to a point where we are   beginning to see signs of lake trout restoration in Lake Huron. Currently, the   populations of sterile lamprey are undergoing fish health screening for all   reportable pathogens. Will the Service’s aquatic species restoration programs in the Great   Lakes be affected by the APHIS emergency order? The restoration of endangered native mussels in the Upper Mississippi River     watershed by the Genoa National Fish Hatchery will be affected by the APHIS     order. Walleye – listed as VHS susceptible fish by APHIS – are used as host     fish for the larvae of native mussels such as the Higgins’ eye pearly mussel.     The Service will work with APHIS to help develop an interim rule that allows     resumption of this mussel restoration effort in the Upper Mississippi River.  Lake trout and other native species the Service stocks into the Great     Lakes, such as coaster brook trout, are not included on APHIS list of     VHS susceptible species. Restoration of these species will not be affected by     the APHIS order.  Service support of state agency stocking programs by federal fish     hatcheries will not otherwise be impacted. Service programs to restore other     endangered, threatened and declining aquatic species are not presently     affected by the APHIS emergency order. What role does the Fish and Wildlife Service play in managing Great Lakes   fish populations?The Service is a participating member of the Great Lakes Fishery Commission's   Fish Health Committee, an intergovernmental, interagency group responsible for   coordinating regional efforts in the Great Lakes basin to prevent introduction   and dissemination of communicable fish diseases. The Service, in its   partnerships with state and other federal agencies, cooperates by lending its   expertise to build sustainable fisheries, recover endangered and threatened   species, and sustain healthy ecosystems and habitats.  Viral Hemorrhagic Septicemia in the Great   Lakes RegionViral hemorrhagic septicemia (VHS) virus is an extremely serious pathogen of   fresh and saltwater fish, and is causing an emerging disease in the Great Lakes   region of the United States and Canada. VHS has been found specifically in the   waters of Lake Huron, Lake St. Clair, Lake Erie, Lake Ontario, and the St.   Lawrence River. Due to its high mortality and severe economic consequences, VHS   is classified as a reportable disease by the World Organization for Animal   Health (OIE). In the past, VHS was thought to be a concern only for trout and a         few other freshwater fish raised for commercial aquaculture in Europe. However,         the recent outbreak in the Great Lakes region appears to be a new strain of the         virus. This new strain is responsible for dieoffs in the following species: muskellunge, smallmouth bass, northern pike, freshwater drum, gizzard shad,         yellow perch, black crappie, bluegill, rock bass, white bass, redhorse sucker,         bluntnose sucker, round goby, and walleye. How VHS was transferred to the Great   Lakes or how long it has been in the ecosystem is not known. The disease   transmits easily between fish of all ages. Mortality is highest at low water   temperatures between 37 and 54 degrees Fahrenheit. Some fish will show no   external signs while others show signs that include bulging eyes, bloated   abdomens, inactive or overactive behavior, and hemorrhaging in the eyes, skin,   gills, and at the base of the fins. Infected fish may also have lesions that   look like those caused by other fish diseases. Therefore, testing is necessary   to determine whether the fish is infected. Sport fishermen and recreational   boaters are asked to adhere to good biosecurity practices while fishing or   boating in waters where VHS has been found. Thoroughly clean fishing equipment,   boats, and trailers before using them in a new body of water and do not transfer   fish from one body of water to another. How You Can Protect Your Facility From VHSAlthough VHS has yet to be detected in aquaculture facilities, individuals     responsible for the movement of VHS susceptible species, regardless of origin,     should take these steps to protect their facilities: Request a health certificate stating that those fish have been tested and     are free of VHS prior to movement.  Enact appropriate biosecurity measures within your facility to prevent the     spread of this, and other, infectious pathogens. Some elements of a     biosecurity plan include:    Cleaning and disinfection      Controlling the movements         of people, animals, vehicles, and equipment      Isolating new and returning (e.g.,         brood stock) fish      Controlling effluent discharges      Conducting audits to         evaluate implementation and effectiveness of the biosecurity plan.  Stay alert for more information about the disease, particularly the names     of species newly found to be susceptible.  If you suspect VHS, you should     immediately report all findings to the State department of agriculture or fish     and game department in your area.

What is   VHS? A.VHS is a highly contagious pathogen of fresh and saltwater fish. It causes     clinical signs including internal hemorrhaging and death in susceptible     species. Some fish will show no external signs while others show signs     including bulging eyes, bloated abdomens, inactive or overactive behavior, and     hemorrhaging in the eyes, skin, gills, and at the base of the fins. Infected     fish may also have lesions that look like those caused by other fish diseases.     Therefore, testing is necessary to determine whether fish are infected. VHS     has been reported in several of the Great Lakes and related tributaries where     a number of large scale die-offs of wild fish have occurred. The disease does     not pose a risk to people, but the VHS virus has been found to infect at least     37 fish species. Q. How did   VHS arrive in the Great Lakes area? A.It is not known how the disease arrived in the Great Lakes area. In the past,     VHS was thought to be a concern only for trout and a few other freshwater fish     raised for commercial aquaculture in Europe. The disease was first detected in     Lake Ontario in 2005 and has since been detected in Lake St. Clair, Lake Erie     and the St. Lawrence River, as well as Conesus Lake. As a result of additional     research, we now know that the disease was present in Lake St. Clair as early     as 2003. Before being detected in the Great Lakes area, VHS was limited in     North America to saltwater finfish from the Atlantic and Pacific oceans. The     recent outbreak in the Great Lakes region appears to be a new strain of the     virus. This new strain is responsible for die-offs in many freshwater species. Q. What   initial action did the U.S. Department of Agriculture (USDA) take in response to   this disease threat? A.On Oct. 24, 2006, USDA’s Animal and Plant Health Inspection Service (APHIS)     issued an emergency order prohibiting the importation of 37 species of live fish     from two     Canadian provinces into the United States and the interstate movement of the     same species from the eight states bordering the Great Lakes. The emergency     order was issued in response to the rapid spread of VHS in the Great Lakes     region. In addition, the Great Lakes strain of the virus impacts a greater     number of fish species. Q. Why did   USDA revise the initial Federal Order? A.Following the release of this emergency order, APHIS held a meeting to     discuss VHS and the development of a federal regulatory program. During this     meeting, APHIS received several recommendations from participants regarding     modifications to the Federal Order that could be made to alleviate impacts on     industry and related businesses in the Great Lakes region while still     protecting against the spread of VHS. On Nov. 14, 2006, APHIS modified the     Federal Order to allow live fish of VHS susceptible species to move from the     eight states bordering the Great Lakes provided that certain conditions are     met. With the exception of salmonids, the movement of VHS susceptible species     from Quebec and Ontario, Canada into the United States remains prohibited     under the Federal Order. Q. Has VHS   been found in commercially raised fish in the United States? A.No. Detections of VHS have been limited in North America to the wild     oceangoing and freshwater fish. The goal of the Federal Order is to prevent     the spread of the disease to aquaculture facilities. Q. What   States are included in the amended Federal Order and why? A.The following states are included in the Federal Order: Illinois, Indiana,     Michigan, Minnesota, New York, Ohio, Pennsylvania and Wisconsin. The states of     New York, Pennsylvania, Michigan and Ohio have experienced fish die offs due     to VHS. While such die offs have not been observed in Illinois, Indiana,     Minnesota and Wisconsin, these states are considered to be at risk of having     the disease because they too are part of the Great Lakes watershed and     unimpeded natural fish movements between these bodies of water can spread the     disease. Entire states rather than watersheds are included in the Federal     Order because of the unrestricted intrastate movement of fish through human     activity. Future surveillance may be able to more closely delineate the     presence of VHS in specific areas. Q. Why is the   Federal Order necessary? A.The goal of the Federal Order is to prevent the spread of VHS into aquaculture     facilities while also preventing the spread of the disease from the Great     Lakes area to uninfected bodies of water. APHIS will continue to gather more     information about the disease in order to provide the best possible protection     against VHS. Q. Is APHIS   going to follow the Federal Order with official rulemaking? A.Yes. APHIS will be drafting an interim rule to further address the     international and domestic movement of VHS susceptible fish. The rule will be     published in the Federal Register along with a notice for public comment. The     Federal Order will remain in effect until the interim rule is published in the     Federal Register. Q. Do the   requirements in the Federal Order only apply to live fish? A. Yes. Fertilized eggs or other     gametes, dead fish, and tissues (organs, blood, scales, etc.) are not covered     under the Federal Order and may continue to move to diagnostic labs or in     commerce. Q. What   conditions must be met under the Federal Order to move live VHS susceptible   species interstate for slaughter? A.In order for live VHS susceptible species to move interstate for slaughter,     the fish must be:  Intended for human     consumption.    Transported to a         state inspected slaughter facility that discharges waste water into a         municipal sewage system that includes waste water treatment. As an         alternative, the facility can also dispose of waste water in a         non-discharging, settling pond or a settling pond with disinfection         according to Environmental Protection Agency (EPA) and state requirements.         Offal, including carcasses, from the slaughter facility must be either     rendered or composted.    Accompanied by the proper         USDA documentation (VS form 1-27) for the movement of restricted animals if     not tested for VH Q. What is a   settling pond with disinfection? A.A settling pond is one of several ways a slaughter facility or processing     plant can remove waste water. Not all settling ponds incorporate a disinfection     process. State agencies overseeing slaughter plants ensure that the     disinfection process meets applicable Environmental Protection Agency and     state regulatory standards. Q. What conditions must be met   under the Federal Order to move live VHS susceptible fish for research and   testing? A.In order for live VHS susceptible species to move to research and diagnostic     laboratories, the fish must be:  Accompanied by the proper USDA documentation (VS form 1-27) for the         movement of restricted animals stating the fish are destined for a research         or diagnostic laboratory. The laboratory must be approved by state, tribal     or federal authorities for aquatic animal health.    Received at a facility         where waste fluids and carcasses are considered medical waste and disposed     of according to EPA and state requirements. Q. What conditions must be met   under the Federal Order to move live VHS susceptible species for purposes other   than slaughter, research or diagnostics? A.In order to move live VHS susceptible species for purposes other than     slaughter, research or diagnostics, the fish must be transported with     documentation from appropriate state, tribal, or federal authorities for     aquatic animal health stating that the fish have tested negative for the VHS     virus under existing national and international standards specified in the     Federal Order. National standards for testing are detailed in the American     Fisheries Society Suggested Procedures for the Detection and Identification of     Certain Finfish and Shellfish Pathogens also referred to as the AFS Blue Book.     The blue book is available online at www.fisheries.org/fhs. International     standards for testing are included in the World Organization for Animal     Health (OIE) Manual of Diagnostic Tests for Aquatic Animals, which is     available online at www.oie.int/eng/normes/fmanual/A_00022.htm. Q. Does this mean that live   fish can move interstate from the 8 states included in the Federal Order if   they test negative for VHS? A.Live fish can move interstate if they test negative for VHS and are     accompanied by documentation from the appropriate state, tribal or federal     authority for aquatic animal health. This documentation ensures that all     testing is conducted in accordance with the Federal Order at an approved     state, tribal or federal laboratory. Q. What type of documentation   is required? A.The appropriate documentation is determined by the competent state, tribal or     federal authority for aquatic animal health. It could be a letter, health     certificate or permit depending on individual state, tribal or federal     requirements. Q. What is a competent   authority for aquatic animal health? A.A competent authority is defined as the state, tribal or federal agency that     has jurisdiction over aquatic animal health. It is recommended that producers     contact their state aquaculture coordinator for more information. A list of     state aquaculture coordinators can be found at www.aphis.usda.gov/vs/aqua/under "General     Information." Q. Who determines whether the   testing meets national and international standards? A.The appropriate state, tribal or federal competent authority in the     originating jurisdiction will make that determination. Q. Do all species of fish need   to be tested for VHS? A.No. Only live VHS susceptible species originating from the 8 states included     in the Federal Order need to be tested before moving interstate. The list of     VHS susceptible species included in the Federal Order can be found at: www.aphis.usda.gov/vs/aqua/.     This list may be updated as our knowledge of species susceptibility     increases. Q. Is testing farm based or   fish lot based? A.The state, tribal or federal competent authority for aquatic animal health in     the originating jurisdiction will make that determination. Q. How can producers find   approved laboratories for VHS testing? A.APHIS recommends that producers contact their state or tribal competent     authority for aquatic animal health. The appropriate authority will determine     which laboratories are approved to test for VHS. These laboratories may     include state, federal and university labs. Q. How can producers find   aquatic animal health professionals to collect samples for VHS testing? A.APHIS recommends that producers contact their state aquaculture coordinator to     provide assistance in locating an aquatic animal health professional. A list     of state aquaculture coordinators can be found atwww.aphis.usda.gov/vs/aqua/ under "General Information." Q. Does the Federal Order have   any implications for the 42 states not included in the emergency action? A. States not included in the Federal Order can continue to move live     VHS susceptible fish species with out restriction. In addition,     fish originating in states not included in the Federal order can transit the     affected Great Lakes states without oversight. Q. Do any requirements other   than those included in the Federal Order need to be met to move live   VHS susceptible species interstate? A.Yes. In addition to the Federal Order, producers need to meet their existing     state requirements as well as any requirements stipulated by the receiving     state. Q. Can live VHS susceptible   fish be imported into the United States from Canada? A. VHS susceptible fish from all     Canadian provinces except Ontario and Quebec can continue to move in U.S. commerce without     restriction. With the exception of salmonids, all live VHS susceptible species     from Ontario and Quebec are prohibited from entering the United States at this     time. VHS susceptible species of salmonid fish may enter the United States from     Ontario and Quebec only if they meet the requirements specified in the U.S. Fish     and Wildlife Service Title 50 Certification. These requirements can be found in     50 CFR 16.13.a.3 and 16.13.b. Q. Does APHIS have plans to   provide compensation for income lost as a result of the Federal Order? A.No. Under the Animal Health Protection Act, APHIS only has the authority to     provide compensation for animals depopulated as part of a disease eradication     program. Under the Federal Order APHIS is not requiring the destruction of     VHS susceptible species, we are only regulating their movement. The revisions to     the original Federal Order allow some movement while still protecting against     the spread of VHS. **USDA   Amends Order on Viral Hemorrhagic Septicemia** The Department of           Agriculture's Animal and Plant Health Inspection Service on Nov. 14           modified an emergency order that prohibited movement of 37 species of           live fish from two Canadian provinces and eight states bordering the           Great Lakes. The modifications allow for   the interstate transportation of fish susceptible to viral hemorrhagic   septicemia out of Illinois, Indiana, Michigan, Minnesota, New York, Ohio,   Pennsylvania, and Wisconsin under certain conditions to help prevent the spread   of the disease. The original prohibition was   a response to several detections of VHS, a disease affecting some saltwater fish   that also has appeared in recent years in wild freshwater fish of the Great   Lakes region (see JAVMA, Dec. 1, 2006, page 1712). The intent was to prevent movement of fish at risk   of harboring the VHS virus while APHIS gathered information and created a   testing and certification program for the interstate transportation of   susceptible species. The conditions for   interstate movement of VHS-susceptible species under the current order vary,   depending on whether the reason for transporting the fish is slaughter, research   or diagnostics, or other purposes. Proper documentation must accompany the fish,   and receiving facilities must dispose of wastewater and carcasses appropriately   to prevent the spread of the disease.

News   Updatesfrom the Aquatic Animal Drug Approval Partnership (AADAP)   Program of the US Fish & Wildlife Service Hydrogen Peroxide Updates GREAT NEWS!!!35% PEROX-AID (hydrogen peroxide) was approved on January 11, 2007 for control   of mortality in: (1) freshwater-reared     finfish eggs due to saprolegniasis,  (2) freshwater-reared     salmonids due to bacterial gill disease, and  (3) freshwater-reared     coolwater finfish and channel catfish due to external columnaris disease. Eka Chemicals, Inc.(Marietta, Georgia), is the sponsor of 35% PEROX-AID.    This is a very important approval because it is: * THE FIRST new     waterborne drug approved for a disease claim for any aquatic species in more     than twenty years.  * THE SECOND aquaculture     drug to gain designation under the Minor Use and Minor Species Animal Health     Act which entitles Eka Chemicals, Inc. to seven years of exclusivity for     marketing rights for the approved label claims.  * THE FIRST new     aquaculture drug with an original approval covering multiple label claims for     use in a variety of finfish species. Various entities played a   role in this significant achievement.  The Upper Midwest Environmental Sciences Center (UMESC; U.S. Geological Survey,   La Crosse, Wisconsin) developed the data that resulted in the approval for these   label claims and did this with financial support through base funds and the Federal-State Aquaculture Drug Approval Partnership Project.  UMESC (1)   wrote the environmental assessment that completed the environmental safety   requirements, (2) performed target animal safety studies on representative   species and their eggs so that all freshwater-reared finfish and their eggs   could be placed on this or future labels, and (3) conducted laboratory and field   effectiveness studies that resulted in these label claims being approved.    Eka Chemicals, Inc. completed the requirements for manufacturing and worked   together with the National Coordinator for Aquaculture New Animal Drug Applications to (1)   complete the requirements for human food safety, labeling, and all other   information on safety and effectiveness and (2) write the original New Animal   Drug Application. 35%PEROX-AID is approved with over-the-counter marketing status and has no       requirement for an acceptable daily intake, tolerance, withdrawal time, or       regulatory method.

(telephone:  800-283-5292 or 360-384-5898; address:  1269       Lattimore Road, Ferndale, WA  98248-9424) as the sole distributor of       35%PEROX-AID. FDA Center for Veterinary   Medicine has indicated that the Low Regulatory Priority Drug status for hydrogen   peroxide is rescinded.  Formerly, facilities could purchase and use most   any brand of hydrogen peroxide that was consistent with FDA's policy.  This   has changed and the ONLY hydrogen peroxide product that can legally be purchased   and used is 35%PEROX-AID and it is for the approved label claims.  To use   35%PEROX-AID to treat additional diseases or additional species not covered on   the current label, licensed veterinarians may be able to prescribe a legal   extra-label use. Oxytetracycline Update: New Formulation Approved for Phibro's OTC Product:Phibro Animal     Health’s NADA (#038-489-pdf)     has now been amended to change the formulation from oxytetracycline     hydrochloride to a dihydrate salt of oxytetracycline. In addition to the     supplement providing for the approval of the dihydrate salt, it also provided     for a change of oxytetracycline concentration in the Type A medicated article,     and the addition of an indication for control of gaffkemia in lobsters. For     more information, view the Federal Register Notice published on 8 August 2006 (pdf). Phibro Animal     Health is to be commended for their efforts in this regard and for supporting   the aquaculture industry. Chloramine-T Update: Supportive Field Study:As part of a joint     effort, the AADAP staff worked closely with researchers from Iowa Department of Natural Resources Rathbun Fish Culture Research Facility this past summer to conduct a field study to substantiate the effectiveness of     20 mg/L chloramine-T to control mortality caused by external columnaris in     walleye Sander vitreus. The study only needs to be considered supportive by     CVM’s Aquaculture Team (based on previous discussion with CVM’s Aquaculture     Team Leader) to substantiate results from a study conducted by Jeff Rach (USGS/UMESC)     that demonstrated the effectiveness of chloramine-T for this claim. The Final     Study Report is going through the internal review process and should be     submitted to CVM with a request for a formal review soon. Many thanks to Alan   Johnson, Jay Rudacille, and Brad Bond for carrying the water on this study.  **Return            to MTAN selection pageReturn to Ashland FRO home pageReturn to Region 3 U.S. Fish and Wildlife Service**  Product and company            names mentioned in this publication are for informational purposes only.
