 Recent hot weather, low water prompts fish kills in southern Wisconsin; citizens asked to report dead fish to DNR
A long stretch of hot weather combined with a lack of precipitation has created low water and oxygen levels in many waterways, said Scot Stewart, DNR south central district fisheries supervisor. “As water temperatures go up, water is not able to hold as much oxygen, which fish need,” said Stewart. “Respiration by plants can reduce the amount of oxygen to levels lethal to fish. That’s when summer fish kills occur.” The four fish kills occurred in the Rock River in Dodge County, upstream from the Horicon dam; near Hustisford in Dodge County at the base of Lake Sinissippi; Beckman Mill Pond in Green County; and on the Yahara River below Lake Kegonsa in Dane County. The department estimates the Rock River kill caused the death of more than 500 fish, mostly carp, but a number of walleye also. The fish kill near Hustisford involved close to 2,000 fish, including a large number of walleye and channel catfish. The agency is still investigating the other two fish kills, said Stewart. “Unfortunately, fish kills due to hot weather and from other factors happen every summer around the state, and we encourage citizens to call the DNR as soon as they think they see one,” said Stewart. Stewart added that the sooner the DNR knows about a fish kill, the more accurate information staff can collect, which helps the department learn the exact causes. To report a potential fish kill, or if you see dead fish, please call the DNR Tip Line at 1-800-TIP-WDNR (1-800-847-9367). Read more here: For more information:

Grant boosts investigations into why bass are booming, walleye waning in some lakes
A consortium of researchers and fisheries biologists from the University of Wisconsin’s Madison and Stevens Point campuses and the Department of Natural Resources have received a $760,000 federal grant over five years to help investigate the shifting fish populations and tease out the most likely reasons behind the shift. Apple River Flowage largemouth “We’re excited to have a large-scale, collaborative research project underway to tackle our key questions and help inform our management decisions,” says Jon Hansen, one of the DNR fish biologists involved in the study and leader of DNR’s bass committee. “The issue is very complicated, and identifying the causes of these changes requires various approaches and the expertise that the different partners bring to the table.” Says Steve Carpenter, a UW-Madison limnologist and a principal investigator in the study, “At this point, we have nothing but hypotheses. Now we can get to work on gathering real information and figuring out which of the many hypotheses might be right.” The grant is funded by the U.S. Geological Survey and will be led at UW-Madison by Carpenter, at Stevens Point by Dan Isermann, and at the DNR by a team of DNR Bureau of Science Services researchers and Fisheries Management biologists. The work will build on, and draw data from, ongoing state efforts to adjust bass and walleye fishing regulations and attempt to determine how much anglers affect these populations. Bass are the fish Wisconsin anglers reported releasing most often in a 2006-07 statewide mail survey, with only 5.4 percent of bass harvested, while 30 percent of all walleye were harvested. “These traditional approaches (changing regulations and collecting data) are important to do, but if that is all we did, we’ve never be able to figure out what this is happening,” says John Lyons, the DNR fisheries researcher who assembled the collaborative research team. “We’d still be speculating. What this study will do is not necessarily provide the solution, but it will narrow down the explanations from 10 plausible reasons to two or three that are highly plausible, and which of our management tools could work.” Read more here: For more information:

Assembly committee takes no action on ‘X-bow’ bill
Wisconsin Outdoor News Contributor Tim Eisele writes: “Madison - The Assembly Committee on Natural Resources heard testimony Jan. 18 on a bill that would allow crossbow use during most firearms seasons for big game and small game, but the committee didn't vote on the bill that day. AB 384 would not allow use of crossbows during the archery deer season beyond the exemptions that already exist - for those 65 and older, and for handicapped hunters. It would allow crossbow use in gun seasons for deer, bear, elk, turkeys, and small game. Read More... | |||||||||||

Wisconsin leads nation in trophy whitetail bucks
MADISON -- The number of trophy bucks taken in Wisconsin has risen by 857 percent in 30 years, with a record-breaking 383 entries during the five years ending in 2010, according to historical records kept by the venerable Boone and Crockett Club. That makes Wisconsin the number one state or Canadian province in North America for trophy whitetail production, muscling up from its earlier position of third. The records show the number of trophy white-tailed deer in North America shot up by 400 percent during the past 30 years. During the period from 1980 to 1985, North American hunters entered 617 trophy whitetails, every one of those antlers scored by a certified Boone and Crocket “measurer,” a designation that can take years to earn. For the period 2005-2010, that number jumped to 3,090 trophy deer, dramatic evidence that North America’s whitetail deer herd has grown by leaps and bounds. One long-time, certified measurer is Marlin Laidlaw of the Wisconsin Buck & Bear Club, also a member of the Wisconsin Conservation Congress big game committee. Laidlaw says Wisconsin’s number one ranking is about a lot more than numbers. Laidlaw said while there is good deer range throughout the state, there are more unofficial refuges now – private lands where deer are not hunted or are hunted lightly – where bucks have a chance to grow older. “Plus, you have people who just don’t care to shoot small bucks anymore,” Laidlaw said.
