State pursues additional testing after silver carp environmental DNA detected in Lower Fox River
MADISON -- Continued surveillance to protect Wisconsin waters against
invasive species has turned up a single positive environmental DNA, or
eDNA, sample for silver carp in the Lower Fox River.The sample, among hundreds taken statewide in recent months, does not necessarily signal the presence of live fish. To determine the source of the eDNA found in the river, the Wisconsin Department of Natural Resources is collaborating with the U.S. Fish and Wildlife Service and has asked the federal agency for its help to collect additional samples from the Fox River in the next two weeks. Asian carp pose significant ecological and economic threats to the Great Lakes region and its fishery because they eat voraciously and compete directly with valuable native fish for food. "The tests for environmental DNA are extremely sensitive and can detect genetic material shed in mucus or excrement from fish as well as from birds that have eaten the fish elsewhere," said Bob Wakeman, aquatic invasive species coordinator for DNR. "Bilge water from boats also can carry traces of the fish. While these genetic fingerprints are clear enough to help us identify specific invasive carp species, the eDNA testing program relies on multiple positive samples over time to indicate the likelihood of live fish." For example, more than 100 additional samples following a single positive detection for silver carp DNA in Sturgeon Bay in late 2013 did not turn up further evidence of the fish. In the latest case, the single positive sample from the Lower Fox River was among 200 samples collected from the river in June and July. The monitoring was part of a coordinated program that included drawing some 1,950 samples from tributaries to Lake Michigan during the summer months. In addition to the federal eDNA monitoring, DNR fisheries team members conduct a variety of netting, electroshocking and trawling operations in state waters as part of the ongoing monitoring effort. To date, these efforts have not captured any Asian carp in any waters of the Lower Fox River, Green Bay or Lake Michigan. "The U.S. Fish and Wildlife Service appreciates Wisconsin's commitment to our shared fight against these invaders," said U.S. Fish and Wildlife Service Deputy Regional Director Charlie Wooley. "At the state's request, we are providing all the resources and technical expertise we have available as part of a multistate effort to prevent the establishment of self-sustaining populations of Asian carp in the Great Lakes." Asian carp species including bighead and silver carp were introduced into the southern United States in the 1970s and eDNA has been found upstream of the electric dispersal barriers in Lake Calumet, seven miles from Lake Michigan on the Indiana-Illinois border as well as in Lake Erie. DNR encourages anglers and others to review Asian carp identification materials, to report any sightings of Asian carp and to make sure that bait buckets don't inadvertently contain the fish because young Asian carp resemble popular bait species. Photo identification tools and more information on Asian carp can be found on DNR's website, by searching Asian carp. More information on eDNA is available from the Asian Carp Regional Coordinating Committee. Results of eDNA monitoring from the Midwest region are posted here.

Michigan muskies getting fit to fight in WisconsinWILD ROSE, Wis. -- Standing sentinel around artificial weeds in the rearing pond at the Wild Rose State Fish Hatchery, newly arrived spotted musky fingerlings from Michigan leave little doubt about their predatory instincts. When a minnow strays too close, the fish dart quickly from the artificial cover, showing off their ultimate potential to make a strong Wisconsin fishery even better. With a few months of steady feeding ahead, these fingerlings will soon gain the weight and size they need for a successful introduction into brood-stock lakes managed by the Wisconsin Department of Natural Resources as well as the waters of Green Bay. "These Great Lakes spotted muskies represent an important step forward in our efforts to restore a strong and naturally reproducing population to the waters of Green Bay and Lake Michigan," said Steve Fajfer, supervisor of the Wild Rose hatchery. "In recent years, the waters of Green Bay, Sturgeon Bay and area tributaries including the Lower Fox and Menominee rivers have become known as great destinations for musky fishing -- particularly in the fall. This strain of fish from Lake Huron should help us create even more exciting opportunities in the years ahead." Tim Simonson, a DNR fisheries biologist and expert on muskies, said the productive waters of the region offer optimal conditions for the fish to grow, with current data predicting an average adult size of nearly 53 inches for female fish and 47 inches for males. "The muskellunge in Green Bay grow relatively quickly and we also see high rates of catch-and-release fishing in the area. These factors really contribute to the area's reputation for trophy fish," Simonson said. "As we continue to diversify the genetics with the addition of these latest fish, we are looking at truly world-class opportunities in the years ahead." Although spotted muskies are native to Green Bay and other Lake Michigan waters, overfishing, loss of habitat and diminished water quality extinguished local populations by the mid-1900s. DNR began a reintroduction program by obtaining spawn from a Lake Huron tributary in Michigan 1989. Additional genetics and fingerlings have come from Lake St. Clair in Michigan as well as Lake Huron's Georgian Bay in Canada. The establishment of brood-stock lakes in Wisconsin starting with Long Lake in 1989 has allowed for more efficient production of spotted musky fingerlings and stocking volume has ranged from 2,000 fish to as many as 30,000 per year in the early 2000s. However, the number of original wild fish that contributed to the brood stock was relatively small and the 2012 Green Bay Great Lakes Spotted Musky Management Plan [PDF] pointed to the need for continued expansion of the source population. "We've been pleased to see that some natural reproduction is occurring in Green Bay and we are finding a limited number of young, wild Great Lakes spotted musky," Simonson said. "However, we believe that with the introduction of a more diverse breeding population and an expanded number of stocking locations, we'll ultimately increase the chances for successful natural reproduction in the region." The new batch of 12,000 fingerlings from Wolf Lake State Fish Hatchery in Michigan is part of a cooperative effort to improve musky genetics in both states. While Michigan recently has focused on the Great Lakes spotted strain, Wisconsin's highly successful inland lake musky breeding program is contributing fish to help expand the inland strain stocking program there. Fajfer and Simonson said prominent Wisconsin musky clubs including C & R Musky Club, Dave's Musky Club, Packerland Musky Club, Musky Club Alliance of Wisconsin, Titletown Muskies and Winnebagoland Musky Club deserve particular credit for supporting the spotted musky stocking effort through the years with donations of time, talent and funds. Residents of Elkhart Lake in Sheboygan County and Anderson and Archibald lakes in Oconto County also deserve recognition for agreeing to serve as brood lakes from which DNR is able to raise fish for spawning purposes. If all goes as planned, some 2,000 of the fierce fingerlings now stalking the ponds at Wild Rose will be transferred to the three brood-stock lakes in summer 2015. The remaining fish are destined for a variety of locations throughout Green Bay in an effort to maximize the use of potential habitat. To learn more about muskies and to find the best spots for fishing this fall, visit DNR.wi.gov and search "musky." Wisconsin's musky season continues through November 30 for the state's boundary and outlying waters including Lake Michigan as well as northern inland lakes. For southern inland waters, the season continues through Dec. 31. Read more here: FOR MORE INFORMATION CONTACT:

Preliminary recommendations from County Deer Advisory Councils regarding deer population objectives will be made Nov. 3, with public comment due Dec. 5MADISON -- County Deer Advisory Councils will release preliminary recommendations regarding deer population objectives Nov. 3. These early recommendations, made on a county-by-county basis, will be open for public comment Nov. 3 to Dec. 5. "Each county's council will review deer herd metrics, work with stakeholders, and weigh comments and concerns from the public in order to develop preliminary population objective recommendations," said Kevin Wallenfang, big game ecologist for the Wisconsin Department of Natural Resources. "CDACs will help make sure anyone with an interest in deer management has an opportunity to provide input before final recommendations are submitted." Through coordination and public involvement, councils will recommend an increase, decrease or stabilization of the deer herd. Those interested in providing comment will have an opportunity to do so through a web-based survey found on the CDAC page beginning Nov. 3. Preliminary population objective recommendations for each CDAC will be posted online. For more information, visit the WIDNR website and search keyword CDAC. Once the public comment period has closed, councils will incorporate feedback from survey responses into final recommendations. Public comments are also welcome as the department reviews the recommendations Dec. 8-18. These comments can be submitted via email . READ MORE HERE ... FOR MORE INFORMATION CONTACT:
