Lansing, Michigan - The Great Lakes Fishery Trust announced today a
$750,000 grant to address viral hemorrhagic septicemia (VHS), a deadly
viral disease in fish. Researchers from the U.S. Geological Survey's
Western Fisheries Research Center, Michigan State University, and
Cornell University have joined together to provide resource managers
in the Great Lakes region with new tools and information to better
understand, predict, and manage the threat posed by this fatal
disease.
The research will compare the effects of VHS on important native
and Great Lakes sportfish, including lake trout and Pacific salmon,
and develop new and faster detection techniques which are key
information gaps on this virus as identified by the Department of
Natural Resources.
"This research allows us to be proactive and focus on the highest
priority needs for this new and emerging disease," said Great Lakes
Fishery Trust Board Chair and DNR Director Rebecca Humphries. "This
funding will provide critical management tools to protect our fish
populations."
First identified in the region as the cause of a large die-off of
freshwater drum in Lake Ontario in 2005, VHS is considered a serious
viral disease of fish. Since that time, a number of outbreaks have
occurred in the Great Lakes with the exception of Lake Superior where
it has not been detected. While having no affects on humans, over 25
fish species have been found with VHS in the Great Lakes region.
Significant losses among muskellunge, walleye, yellow perch,
smallmouth bass, round gobies, bluegill, black crappie and gizzard
shad have been seen during the period from 2005-2007. It is not known
how VHS was introduced to the Great Lakes, or exactly how long it has
been in the ecosystem, but the discharge of ballast water from
ocean-going vessels is a prime suspect. Within the Great Lakes region,
movement of infected baitfish has also been suspected as the source of
VHS that has been found in certain inland lakes of New York, Michigan
and Wisconsin.
"This intensive, multi-research institute focus on VHS offers the
best approach to effectively respond and manage VHS in the Great Lakes
region," said Dr. James Winton, chief of U.S. Geological Survey's Fish
Health Section. "The Great Lakes Fishery Trust is a key funding
partner in this effort and should be recognized for this valuable
contribution."
The Great Lakes Fishery Trust (GLFT) was established in 1996 as a
result of a settlement agreement with the Ludington Pump Storage
Utility Plant on Lake Michigan. The mission of the GLFT is to provide
funding to enhance, protect, and rehabilitate Great Lakes fishery
resources. Since inception, the GLFT has awarded over $30 million to
enhance and protect fishery resources and provide enhanced shore-based
angling access.
