No Asian carp environmental DNA found after additional testing in Lower Fox River

MADISON, Wis. -- Additional tests for Asian carp environmental DNA in the Lower Fox River have come back negative, Wisconsin Department of Natural Resources officials said.

Bob Wakeman, aquatic invasive species coordinator for DNR, said the additional tests were requested after one out of 200 sample collected in June and July from the Lower Fox River tested positive for silver carp. The latest round of testing - by the U.S. Fish and Wildlife Service - included collecting 200 additional samples from the Lower Fox River on two days of sampling in the weeks following the initial results.

"We're pleased that the results came back negative and it's a good indication there are no live silver carp in the river," Wakeman said. "We're particularly grateful to the U.S. Fish and Wildlife Service for their work in carrying out the water sampling and analysis. Through continued monitoring and the preventive efforts of Wisconsin anglers, waterfowl hunters, recreational boaters and commercial partners, we hope to keep Asian carp out of Lake Michigan."

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. Asian carp species including bighead and silver carp were introduced into the southern United States in the 1970s.

The tests for eDNA 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. Contaminated bilge water also can carry traces of the fish and the latest negative results suggest the source of eDNA from the summer sampling originated from a temporary source.

While the genetic fingerprints are clear enough to identify specific invasive carp species, the eDNA testing program relies on multiple positive samples over time to indicate the likelihood of live fish. The single positive result among 1,950 samples from Wisconsin tributaries to Lake Michigan in June and July followed by the negative results returned this week recalls a similar situation in 2013. Then, a single positive sample from the Sturgeon Bay area was followed by all negative results.

In addition to the federal eDNA monitoring, DNR fisheries team members conduct a variety of netting, electroshocking and trawling operations in state waters. To date, these efforts have not captured any Asian carp in any waters of the Lower Fox River, Green Bay or Lake Michigan.

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, dnr.wi.gov, by searching "Asian carp."

Fishing the Fox River at De Pere for Monster Spring Walleyes

Author: Craig Buchinger
March 2014

Nothing marks the start of spring like the thousands of walleyes that migrate up the Fox River each year...and the anglers that follow them. The walleye fishing on the Fox River is world class and offers a good chance at a walleye weighing more than 10 lbs. Understanding the dynamics of this river, such as how water clarity can change with precipitation and runoff, is critical to finding and locating big walleyes; and getting them into the boat.

Moving beyond PCBs: improving water quality in the Lower Fox River and Green Bay

Public has until July 26 to comment on the draft Total Maximum Daily Load

MADISON - The public has an opportunity to comment on a new report that explains efforts to improve water quality in the Lower Fox River and Lower Green Bay and tributary streams. Fourteen water bodies in this watershed do not currently meet water quality standards.

The Wisconsin Department of Natural Resources, in conjunction with local stakeholders, has developed what is basically a “pollution budget,” for the Lower Fox River Basin and Lower Green Bay. Known as the Total Maximum Daily Load (TMDL), the plan establishes the total amount of phosphorus and total suspended solids that water bodies covered by the TMDL can receive and still meet water quality standards.

A public informational hearing to learn about the draft TMDL and to provide oral comments is set for July 12, 2010, in Grand Chute. People also may submit written and electronic comments through July 26, 2010, with details provided below.

“This is an important step forward in cleaning up the Lower Fox River and Green Bay,” says Bruce Baker, DNR’s top water quality official.

“In order to improve water quality, all sources of total phosphorus and total suspended solids will need to be reduced,” Baker says. “DNR will work together with stakeholders to find solutions and reduction strategies to meet the water quality goals of the TMDL in concert with the cost effective framework that is in the proposed phosphorus rules.”

The TMDL document details the amounts of phosphorus and total suspended solids each of those waters can receive and still meet water quality standards, and identifies the reductions needed from each source of those pollutants, says Nicole Clayton, DNR coordinator for the lower Fox River TMDL project.

“Once we determine the total amount of a pollutant a body of water can receive and still meet water quality standards, we can calculate needed reductions from specific sources,” she says.

Phosphorus is a naturally occurring nutrient that also is found in soils, livestock manure, commercial fertilizers and wastewater discharges. It fuels algae and plant growth, sometimes leading to excessive levels of both. Total suspended solids include small particles of materials such as soil and leaves that get washed into streams and make the water look muddy and cloudy and degrade habitat for fish and other aquatic life. These pollutants reach rivers and streams from polluted runoff from farm fields, barnyards, residential yards and wastewater treatment plant discharges.

DNR developed the TMDL with help from the U.S. Environmental Protection Agency and a private consultant, the Cadmus Group, Inc., and with feedback from science, technical and outreach teams including various stakeholders groups and the public.

The goal for Lower Green Bay is to improve water clarity to support a diverse biological community and expand the area of beneficial bottom-dwelling plants. To meet established targets, a certain percentage reduction is needed in different types of pollutants. Upon reaching these goals the local streams and Green Bay will have better dissolved oxygen levels, less turbid water, and fewer algae blooms. This is expected to improve habitat for fish and aquatic life and improve recreational opportunities, Clayton says.

The public informational meeting begins at 1 p.m. Monday, July 12, at the Grand Chute Town Hall, 1900 Grand Chute Blvd.

As part of the review and submittal process for TMDLs, a 30-day public comment period runs through July 26, 2010. People may submit written or electronic comments to Nicole Clayton at the DNR, WT/3, 101 S. Webster, Madison, WI 53703 or nicole.clayton@wisconsin.gov.

People can view the draft TMDL report and formal public notice on the DNR website.

Port of Green Bay Webcam

Hey! Why not check out the web cam at the mouth of the famous Fox River in Green Bay, WI. The Fox is well known Nationally for it's Walleye, Musky, Catfish and so much more as it runs up to the Depere Dam. It has been the home of many recognized tournaments. The "Cam" is located near the Green Bay Yacht Club and you can get a perfect view of the Leo Frigo Bridge (formerly Tower Drive Bridge) as well.

There are those that say on certain very dark nights you can see a mysterious glow coming from above the Lambeau Field area.

Input session planned on Fox River & Lower Green Bay “Area of Concern”

DNR and US Environmental Protection Agency to host

GREEN BAY - The Wisconsin Department of Natural Resources and the United States Environmental Protection Agency will host a public input session for the Lower Green Bay and Fox River Area of Concern on Thursday July 23rd from 6:30 to 8:30 pm at the Bay Beach Wildlife Sanctuary Nature Center Auditorium.

In the 1980s, Lower Green Bay (out to Long Tail Point and Point Au Sable) and the Fox River below the De Pere Dam were listed as one of 43 Great Lakes Areas of Concern by the International Joint Commission of Canada and the United States.

Areas of Concern are places where contaminated sediment, poor water quality, or habitat problems affect the use of the waterway such that it needs priority attention. Goals or targets must be set, and then met, for each of the problems before the area can be considered restored. The end goal is for all of the Areas of Concern to be restored and protected so that they can be “delisted,” or removed from the list of Great Lakes Areas of Concern.

The purpose of this public input session is to share information about problems in the Area of Concern and restoration goals (known as “delisting targets”) that have been developed to address them. Input received at the session will be included in the Lower Green Bay and Fox River Area of Concern delisting targets report that will be finalized in the summer of 2009.

Problems identified in the Lower Green Bay and Fox River Area of Concern are related to: fish and wildlife habitat, populations, health, and consumption advisories. Other populations including plankton (free floating plants and animals) and benthos (bottom living plants and animals), nutrient pollution and undesirable algae, beach closings, aesthetics, and restrictions on drinking water and dredging.

Identifying the restoration goals for each of the problems is only one step in removing Lower Green Bay and Fox River from the list of Great Lakes Areas of Concern. “The process will take time and commitment, and like most of the other Areas of Concern, restoration is still in progress, “ said John Perrecone, RAP/AOC Program Manager for the US EPA Great Lakes National Programm Office. Of the 43 Great Lakes Areas of Concern designated in the United States and Canada, only three have been delisted and two more are considered in recovery.
