Fishing rules aim to curb spread of disease in baitfish The Associated Press (4/20) The state of Michigan has new fishing regulations that are designed to curb the spread of fish diseases and fight invasive species. Michigan State University assists Michigan DNR in illegal bait investigation Lansing State Journal (11/19) Michigan State University assisted the Michigan DNR in an investigation of uncertified bait that netted a $2,000 settlement. Documentary being shot in Rhinelander, Wis. on controlling Great Lakes invasive species WTAQ - Rhinelander, WI (8/8) A Chicago-based film crew was in Rhinelander, Wis. this weekend to shoot part of a one hour documentary on the efforts to control invasive species in the Great Lakes. Brule Hatchery could close, others may open Ashland Current (5/17) A study released this week on Wisconsin’s 17 fish hatcheries says it will take $155 million to moderenize them.
Efforts to bolster lake herring populations in Lake Huron may be stunted by deadly disease Great Lakes Echo (12/8) Although Michigan officials want to bring lake herring back in Lake Huron, there’s a new concern – the fish are highly susceptibility to an emerging fatal disease: Viral haemorrhagic septicaemia virus.
Viral Hemorrhagic Septicemia (VHS) is a viral fish pathogen that has invaded the Great Lakes, threatening native fish populations. As its name suggests, this is a serious systematic disease that often causes fish to hemorrhage which can result in individuals bleeding to death. Typically found in marine fish, VHS was found in the Great Lakes in 2005 and 2006 with the occurrence of large fish kills in lakes Huron, St. Clair, Erie, Ontario, Michigan, and the St. Lawrence River. VHS-infected fish died by the thousands, including muskies, freshwater drum, yellow perch, gizzard shad, redhorse, bluegills, black crappie and round gobies. Other species of fish—Chinook salmon, walleye, lake whitefish, white bass, rock bass, smallmouth bass, emerald shiners, spottail shiners, burbot, northern pike, channel catfish, lake trout, rainbow/steelhead trout, and white sucker—also were infected, but did not die in large numbers.
This viral invader is not a threat to people handling or eating infected fish, but can be deadly to more than 15 fish species and can infect at least another 10 species in the Great Lakes basin. This is the first time a virus has affected so many different species across such a wide range of Great Lakes fish families.

Studies, Assessments and Management Plans
Emergency Prevention and Response Plan for Viral Hemorrhagic Septicemia (March 2008) National Park Service and Grand Portage Band of Lake Superior Chippewa This plan is focused on (1) preventing VHS contamination of the waters of the four units of the National Park Service located in the Lake Superior basin and the Grand Portage Indian Reservation; (2) detecting the introduction of VHS; and (3) responding to VHS detection and outbreaks.
Evaluation of the Efficacy of Iodophor Disinfection of Walleye and Northern Pike Eggs to Eliminate Viral Hemorrhagic Septicemia Virus – Fact Sheet (January 2009) U.S. Geological Survey This factsheet presents the results of a study that assessed the effectiveness of chemical disinfection for eliminating VHSv (strain IVb) from fertilized eggs of walleye and northern pike intentionally challenged with VHSv following egg fertilization.
Focus on Fish Health: VHS Viral Hemorrhagic Septicemia Iowa State University, U.S. Department of Agriculture - Animal and Plant Health Inspection Program Launched as part of a national outreach campaign to educate the public about VHS, and to inform individuals involved in recreation and aquaculture about the simple precautions that can be taken to help prevent the spread of the virus.
Molecular Epidemiology of Viral Hemorrhagic Septicemia Virus in the Great Lakes Region (January 2008) U.S. Geological Survey The purpose of this factsheet is to review the results from molecular analyses that have added to our understanding about the distribution and spread of VHS.
Surveillance for Viral Hemorrhagic Septicemia Virus in Wild Fish in Canada (March 2008) Canadian Food Inspection Agency The CFIA implemented a 2-year bilateral surveillance of wild fish in Canada for the presence of VHS virus in the spring of 2007.
