Invasive vs Native Mussels: What's the Difference? When you work in the realm of invasive species, your first thought when hearing the word mussel is "uh-oh". You start thinking, "Ok, which one? Zebra mussel or Quagga mussel?". But then you remember that there's a whole different kind of mussel; Wisconsin's native freshwater mussels. These [...]

Menasha Lock Re-Opening Plans Put On Hold Indefinitely

Cost for Electric Fish Barrier Significant, Board Votes to Stop Project

Original Story: Fox River Navigation System Authority

The Fox River Navigational System Authority (FRNSA) board voted in late June to halt work on the Menasha lock re-opening project, with no set date for resuming development of an electric barrier in the lock channel.

The Menasha lock (located between Lake Winnebago and Little Lake Butte des Morts) had been the most-used lock in the system between Lake Winnebago and Green Bay. After the discovery of a round goby below the Neenah dam in 2015, FRNSA voluntarily closed the lock in an effort to keep the invasive fish out of Lake Winnebago. Since then, the round goby has become abundant in the Fox River and Little Lake Butte des Morts.

The FRNSA has spent more than $750,000 on a proposed electronic barrier which would have allowed boats to pass through the lock, but emit a DC current to repulse fish from entering the lock channel.

However, with an installation cost of $7 million, plus an annual operating cost of $300,000-$400,000, the FRNSA board voted to stop work on the project. Since 2015, FRNSA has been working with experts in aquatic ecosystem management to design a plan using a system of an electric deterrent barrier and water flow regulation at the Menasha lock. Board members indicated further work on the proposal was not within the organization’s budget.

Prior to closing the Menasha lock, it had been the busiest lock on the system; now the DePere lock is the busiest. The locks are the only way the Fox River is navigable—from Menasha to the Bay of Green Bay the river drops in elevation 168 feet. From the Menasha lock to the Rapide Croche lock the river has 17 miles of navigable water. On the northern end of the river from Rapide Croche to the Bay of Green Bay the river is navigable for 20 miles.

“Our goal has always been to restore navigation of the Fox River through the lock system, but we also want to ensure we are protecting the waterways,” Ramlet said. He added FRNSA has maintained a testing program for invasive species for years.

Update: 2022 Spiny Waterflea Findings in Lake Winnebago

On: April 24, 2024

Additional Monitoring Reveals No Other Spiny Waterfleas

Following up from a spiny water flea finding in Lake Winnebago in 2022, the WI Department of Natural Resources and local partners conducted extensive monitoring for spiny water fleas through the summer and fall of 2022. Biologists were searching for additional adult spiny waterfleas as well as eggs that would have been laid in the sediment of the lake. Following analysis of the samples collected, we are please to report that no evidence of spiny waterflea were found which includes not finding any eggs!

This is fantastic news for our waterways! Currently, there is no evidence that the spiny waterfleas found in 2022 were able to establish a population in Lake Winnebago. Ongoing monitoring by UW-Green Bay as part of the Fox River Navigational System Authority (FRNSA) AIS Monitoring Program will continue to keep an eye out for spiny waterflea and other invasive species.

Remember- an ounce of prevention is worth a pound of cure. It’s easy to help prevent the spread of all aquatic invasive species between lakes. No matter what lake or river you visit, follow these steps to protect your wild places:

Spiny waterflea on a fingertip

· Inspect equipment (boats, fishing line, etc.) for attached aquatic plant, animals, or mud

· Remove all attached plants or animals

· Drain all water from buckets and containers

· Never move live fish away from a waterbody (fish out of water = dead)

Waterfowl Hunting? Protect Those Places

Take 5 Minutes Each Hunt for Invasive Species Prevention

Original Story: WDNR

Invasive species are nonnative plants, animals and diseases that cause great ecological, environmental or economic harm. Some have already been found in Wisconsin, while others pose a large risk of surviving and causing problems if they are introduced and become established here.

Just a few minutes of preventative action can help preserve and protect hunting lands for generations to come.

Before launching into and leaving a waterbody, waterfowl hunters should:

– Inspect waders, boats, trailers, motors and hunting equipment, including boots, blinds and dogs

– Remove all plants, animals and mud to the best of their ability

– Drain all water from decoys, boats, motors, livewells and other hunting equipment

– Remove all seed heads and roots when using vegetation for duck blinds

– Never move plants or live animals, such as snails, away from a water body

Lots of hunting spots have boot brush stations to help you clean off your gear (see picture). Want to have one installed at your favorite hunting spot? Contact Chris using the info below!

Be Careful With Those Plants; Dispose but Don’t Release!

Original story: Melinda Myers

As we start see leaves drop, lots of folks are starting to prepare their homes and gardens for winter. If you’ve got a water garden, you’ll be starting to do the same thing! Water gardens make a great addition to any landscape masking unwanted noise, inviting songbirds to take a drink, and providing a beautiful oasis in any landscape. Fall is the time to prepare your water garden for winter. Tropical plants need to be moved indoors and aggressive or invasive plants should be removed and disposed of properly. Contact your local municipality for tips on disposing these and your local Department of Natural Resources for a list of invasive plants in your area that need to be removed. Eliminating invasive plants from our landscapes helps keep them out of our lakes and waterways!

With a history of popular water garden plants being released in our region, following these steps is an easy way to be a steward for your local waterways and your water garden!

Pet Rehoming Event in Green Bay Sees Eight Exotic Pets

On: September 25, 2023

In: 2023, aquatic invasive species, Bay of Green Bay, Exotic, fox-wolf, Green Bay, Habitattitude, invasive, invasive species, Lower Fox River, Outreach and Education, PET, surrender

Original Story: J&R Aquatic Animal Rescue

Eight animals were turned in at an exotic pet surrender event at the Barkhausen Waterfowl Preserve in Brown County on Sunday September 24th. Included in the surrenders were fish and two yellow bellied sliders!

Area organizations were on hand accepting fish, invertebrates, reptiles, pet birds, small mammals, and plants — no questions asked.

In some areas, there are no rehoming options for exotic animals such as fish, birds, and reptiles. Some pet owners that are unable to care for their pet may think that releasing the animal is the right thing to do, however, releasing a pet is harmful for the animal and the environment. Pet Surrender events are now being held across Wisconsin help provide an avenue to pet owners to rehome pets without harming the pet or the environment.

There are multiple places that are currently tackling issues from illegally released domestic and exotic animals. The most well known example are the Burmese pythons that have had an enormous impact on the Everglades in Florida. However, multiple cases of released pets causing problems in our waters occur every year including an alligator found in Long Lake in Summer 2022! Released pets can easily become nuisance or invasive species if they start a breeding population.

The Pet Surrender event brought together a collection of area rehoming partners that provide responsible alternatives to release for exotic pet owners who are no longer able to care for their pets. J&R Aquatic Animal Rescue (JRAAR) hosted the October 30th event with help from several other area organizations including Fox-Wolf Watershed Alliance and University of Wisconsin Sea Grant/Water Resources Institutes.

Invasive Tracking: Researchers trying to trace zebra mussel infestations

While initial populations of invasive zebra mussels were brought to the Great Lakes on boats and in freighter ballast water, a new source of the invasive species has researchers concerned — pet stores.

The Minnesota Aquatic Invasive Species Research Center has partnered with the University of Minnesota Genomics Center to genetically trace zebra mussels that have been found in aquarium moss balls in pet stores.
