Diving on the St. Croix

During September, several Region 3 scuba divers completed dives twice a week to check for gravid winged mapleleaf mussels on the St. Croix River near Saint Croix Falls(WI). Winged mapleleaf mussels are listed as endangered at both the state and federal level. This was, by far, the highlight of my diving season since I had the chance to observe several different mussel species displaying their lures to attract potential host fish. On one of my dives, we had the chance to observe two winged mapleleaf that were gravid and actively displaying. Nathan Eckert from the Genoa National Fish Hatchery brought these animals back as brood stock for future recovery efforts.

Welcome Aboard

Jenna

We’ve all heard the saying “Third time’s the charm.” This statement rang true during October in a mutually beneficial manner when Jenna Merry resumed working at the La Crosse FWCO … now as a permanent employee! Jenna first began working here during the summer of 2010 as a Student Temporary Employee while enrolled as an undergraduate at Winona State University. She returned to work here again in 2012, on a part-time basis, while enrolled in graduate studies at the University of Wisconsin-La Crosse where she earned a Master of Science degree (Biology) in 2015. Jenna left our office earlier this year to work briefly for the Carterville FWCO in Wilmington, Illinois, where her primary duty was keeping Asian carp out of the Great Lakes. Jenna is a now a fishery biologist at our office whose focus will be to help prevent/control the spread of aquatic invasive species in the Upper Mississippi River Basin. Welcome home and back on board!

Kids Ice Fishing Day Sets Record

crowd All,

Many thanks for all that you did to make the Kids Ice Fishing Day a success this year!  Over 355 children were registered, and including their parents and/or guardians over 608 tickets were handed out.  So attendance was well over 600 people that came out to spend a morning on the ice with us, not including volunteers and staff!  Many thanks to the Midwest Fisheries Center, our Friends of the Upper Miss, and the Genoa staff for making the event run like clockwork.  Here’s hoping that many memories were made that will last a lifetime, and that the attendees can carry an outdoor ethic to their children in the future.
Thanks again for your willingness to pass on your love of the outdoors to the next generation and your efforts to preserve the natural resources of the Upper Mississippi River Region.
Sincerely,

Doug Aloisi

Connecting Children with Nature

Last month students from Southern Bluffs Elementary, Summit Environmental and Lincoln Middle Schools (LaCrosse WI) spent the day trading in text-books for hands on learning at the Genoa National Fish Hatchery. The hatchery partners with Southern Bluffs, Lincoln and Summit schools to support their mission of providing students with a solid educational foundation in the core academic areas with an environmental focus integrated throughout the curriculum. This directly correlates to the U.S. Fish and Wildlife Service’s connecting children with nature initiative. Genoa collaborates directly with teaches to match activities at the hatchery with corresponding class work. Students visit the hatchery in fall, winter and spring each year as part of the outdoor classroom and Genoa staff members also visit the classroom for in class lessons. In class lessons consist of native fish identification, fish anatomy, native fresh-water mussels and monarch restoration and habitat enhancement. During the first session of outdoor classroom students experience hands on learning activities based off of lessons in the classroom.animal tracks

 

 

 

 

Students make and identify different animal tracks

In the fall students tour the hatchery and learn about the importance of aquatic resource management and the role the hatchery plays in sustaining and recovering fish and mussel populations. In winter students learn about animal tracks, furs, and experience the history and sport of trapping and importance of trapping as an effective management tool. Students also grow milkweed in the classroom over the winter months for planting on hatchery grounds in the spring. During spring session the students will have a tour of the hatchery to see how the fish have grown overwinter. This allows students to observe different species of fish and life stages from eggs through adults. The students end their day with a lesson on prairie restoration and the ecological benefits of prairies to many species of animals. In addition students plant milkweed that was grown over the winter in the classroom. Students also use quadrats to assess the amount of cover of different species of prairie grasses and possible invasive plants. This data allows the hatchery to assess its restoration practices and take action where needed. These hands on experiences trap memories and instill conservation in the minds of these future stewards of our natural resources.

Mussel Host Test Conducted at Genoa

In an effort to further Genoa National Fish Hatchery’s mussel production the staff at the hatchery is constantly looking for ways to improve methods. Some improvements may come in the form of culture facility updates and others may come in the form of simply trying new things with fish. Production of the black sandshell at Genoa is an example of our constant efforts to get better. The black sandshell is widely known to use walleye and sauger as hosts for their glochidia, however with the uncertainty of how pond production can go sometimes the station is stuck in a position where there are simply not enough fish for mussel production goals. Enter yellow perch. Yellow perch are also raised at Genoa NFH and we consistently produce large year classes that are not as common with walleye production. Yellow perch and walleye are closely related and are both members of the perch family; therefore it was thought that perhaps black sandshell could utilize yellow perch as a suitable hose as well. In December we set up a small host test to determine if we were on to something. The glochidia from a black sandshell were used to inoculate 10 yellow perch. They were maintained in our aquarium system for two weeks while we counted the live and dead mussels that dropped off. In the end we recovered 160 live juvenile mussels. This equals 16 per fish and less than 2% transformation of all the glochidia that attached to the fish. Walleye and sauger will transform over 70% of attached glochidia and usually yield over 700 juveniles per fish. A moderate host for this species would be expected to transform at least 30%. While our results didn’t provide a host to be used for hatchery mussel production we did find that the larvae could transform at some level on the yellow perch. This trial won’t change future work at the hatchery, but we wouldn’t know if we didn’t take the time to try.

Construction of Genoa National Fish Hatchery’s Visitor Center continued despite high temperatures of the single digits being reached in some of this winter’s coldest weather. Construction crews from C3T Inc., of Milwaukee Wisconsin continued steel erection and buttoning up the building so work could continue in a somewhat controlled environment, at least compared to outside temperatures.

The Visitor Center is aptly named the Great River Road Interpretive Center due to the project receiving a grant from the Department of Transportation’s Scenic Byway Program. The Scenic Byway Program is a grass-roots collaborative effort established to help recognize, preserve and enhance selected roads throughout the United States. The U.S. Secretary of Transportation recognizes certain roads as All-American Roads or National Scenic Byways based on one or more archeological, cultural, historic, natural, recreational and scenic qualities, and State Highway 35 which intersect the hatchery has been selected as one of America’s scenic byways.

The purpose of the center will be to interpret and inform travelers of the great history of the local area, the conservation history and value of local natural resources, and local history exhibits of the area such as the Blackhawk war, in regards to its local and national significance.

Timeline for completion of the building is somewhat fluid due to weather and material constraints; construction completion is still planned for the fall of 2016. Exhibit design and construction will continue into the winter with building opening tentatively scheduled for the spring of 2017. The Genoa NFH staff is excited about the new center and looks forward to the benefits it will add to our outdoor classrooms and conservation education program.

Monarch Recovery Effort

butterflies
In response to declining monarch butterfly habitat the Genoa National Fish Hatchery has made it a priority to participate in a Monarch Joint Venture to conserve monarch butterfly habitat along their 3,000 mile migration route. Last fall, staff at Genoa collected hundreds of pods from two different types of milkweed containing thousands of seeds. Those seeds were planted around the hatchery grounds including the native prairie and notable increases in common milkweed and swamp milkweed plants were seen. Throughout this past summer adult monarchs and monarch caterpillars were seen all over the hatchery on the milkweed ensuring that the efforts taken were successful. Milkweed plants are an essential diet for monarch caterpillars and adults feed on the nectar of the flowers. Providing an area rich in milkweed will attract adults continuously to lay their eggs on the plants. This fall staff was at it again collecting even more seed pods than the previous year in hopes of providing even more essential habitat next summer for the migrating monarch butterflies. Genoa has also taken additional steps in monarch conservation in the form of information about monarchs available to the public, milkweed and monarchs in the classroom, as well as including information and trips around the wetland to explain monarch life history and habitat on guided tours. The staff at Genoa is looking forward to informing the public about the importance of monarchs and steps that can be taken to assist in recovery of these butterflies. Information can also be found on the internet for anyone who is interested in the status of monarch butterflies and steps that can be taken assist maintaining butterfly habitat as well as information on flower gardens to help attract them on their migration routes.

USFWS Sends Sturgeon delegation to China

Chinese

Bill Wayman observes a captive sturgeon

On November 10th a delegation of 6 fish biologists from across the US traveled to China to take part in an information exchange between the two countries concerning sturgeon conservation and propagation. The delegation was comprised of biologists with varying backgrounds, yet all working with sturgeon at their stations. From the Midwest Region 3, Beka McCann from the La Crosse Fish Health Center, Dave Hendrix from Neosho National Fish Hatchery and Angela Baran from Genoa National Fish Hatchery were selected for the group. China has eight species of sturgeon, three of which are now listed species. The Chinese sturgeon was listed as a protected species in 1994 and the country has been working to prevent extinction and restore it through habitat conservation, propagation and stocking, fishing regulations and commercial production to eliminate the need for harvest. There are less than 1,000 Chinese sturgeon left due to the same stressors experienced in US sturgeon populations; loss of habitat due to pollution or construction of dams and over fishing (or getting caught as bycatch in nets), recovery of the species is slow due to the life history of sturgeon: mature after 15 -20 years and only spawning every 3-5 years.
The Chinese sturgeon spawns only in the Yangtze River and has lost a large portion of their spawning route due to the construction of 2 dams as well as the loss of their staging grounds in the Yangtze River Estuary. The delegation trip followed the route of the sturgeon along the Yangtze River, visiting hatcheries, nature reserves and two dams as well as the commercial production facilities of Kaluga Queen. The Ministry of Agriculture has set up two critical Nature Reserves for the Chinese sturgeon, the Yangtze River Estuary Nature Reserve and the Hubei Sturgeon Reserve.

 

pens                                                        Sturgeon in net pens

The estuary serves as critical habitat used by fingerling lake sturgeon as they migrate out to sea and for the spawning adults who may stage there for 1-2 years before travelling up the river to the spawn-ing site. The adults will also return to the estuary to feed, regain their strength and reacclimate to saltwater after spawning before they go back out to sea. Construction of the Gezhouba Dam on the Yangtze River near Yichang shortened the spawning route of the Chinese sturgeon by eliminating any possible passage upriver. The Hubei Sturgeon Reserve was established in 1996 to preserve the critical spawning habitat now used by the sturgeon just below the dam. There are conflicts between protection of the species and development of the city. Protection of the site is now forcing developers to design and build in more sturgeon friendly ways, such as no construction structures in the river, so bridges must span the entire width of the river and while work is being done, lights and noise must not disturb the sturgeon. In addition to protection efforts, a hatchery in Jingzhou City was established in 2012 to propagate juvenile sturgeon for stocking efforts. To reduce the impact on native species and still support the demand for caviar and sturgeon, the Ministry has allowed commercial aquaculture to obtain gametes from wild fish several years ago to begin a brood line for captive rearing. The company is now using the second captive generation for production, no wild fish have been used in over 15 years.

In exchange, the company provides juvenile fish for several other aquaculture companies and releases fish back into the wild for restoration efforts as well. The Kaluga Queen company uses both intensive (hatchery buildings) and extensive (net pens in lakes) to raise sturgeon for caviar, meat and leather. To minimize the possible environmental impact from the net pen culture in Qiandao Lake, the company employs a dual pen system and has created a cleaning system. The sturgeon are reared in the top pen with another species in a secondary pen to capture any waste feed. They have devised a collection system under the pens for the fish waste that can be siphoned out, filtered and then the water returned to the lake.
This trip highlighted both the similarities and differences between sturgeon restoration in the two countries, allowing both sides to share information and obtain possible new methods for culture or conservation efforts. Both countries hope to preserve the native populations and to educate the public to create a sense of stewardship for the resources, ensuring future generations continue the fight to preserve these great fish.

This summer we tested a culture unit known as a SUPSY for rearing sub-adult mussels to a size suitable for stocking. SUPSY stands for suspended upwelling system and is made from a pair of two gallon buckets nested together with window screen cut-outs to allow water flow through the unit. Air flow provided by a blower creates lift that continually circulates water through the system. A total of eight SUPSY units were placed in the Ice Harbor at Dubuque, Iowa this spring in cooperation with the National Mississippi River Museum and Aquarium. The eight units consisted of six sets of fatmucket and two sets of Higgins’ eye mussels. The mussels were monitored from late May through early October. During that time they were visited on a two week schedule for routine cleaning and data collection. The trial proved to be successful, with good growth and survival.

The results speak for themselves with 481% growth and nearly 96% survival for fatmuckets and 210% growth and a little more than 80% survival for Higgins’ eye. And more importantly, the mussels exceeded growth rates that could be expected using methods currently available at the hatchery. The Museum and Aquarium was able to incorporate the SUPSY maintenance with their summer outreach programs providing a valuable benefit for both stations. We wish to thank the Museum and Aquarium for their assistance on this project and we look forward to continuing the partnership in the future.

Isolation Building Currently Home to Lake Trout and Future Home to Whitefishes

As lake sturgeon culture and pond harvest wrap up for the fall, Genoa National Fish Hatchery (NFH) staff begin to focus their attention on hatching cold water fish during the winter months. Currently lake trout eggs are beginning to hatch as we wait for new arrivals of coaster brook trout and rainbow trout eggs.

Genoa NFH staff member Jeff Lockington collected wild lake trout eggs from Cayuga Lake, New York. The hatchery collects gametes from approximately 100 pairs of lake trout to maximize genetic contribution for future brood lines. Eggs collected from Cayuga Lake are shipped back to the Genoa NFH for incubation in the current regional isolation facility. As the eggs begin to hatch, an equal representative sample of fry are transferred to culture tanks for grow out. Lake trout are held in the isolation facility until clearing three separate disease inspections by the La Crosse Fish Health Center. Once the lake trout clear disease inspection after two years, they are transferred to Iron River NFH in Wisconsin and Sullivan Creek NFH in Michigan. These fish will serve as future broodstock in the National Fish Hatchery system.

Addition to Isolation Building. Credit: USFWS

Construction is currently underway on a new 90 square foot addition to the isolation building. In the future, this addition will be home to bloater chubs and other species of coregonids (whitefishes). These fish are an important part of the prey fish community in the Great Lakes and serve an important role in many predator-prey relationships. In an effort to reestablish these species the U.S. Fish and Wildlife Service has partnered with multiple agencies to create broodstocks to assist in the reintroduction of lake herring and whitefish in the Great Lakes. Bloater chubs have experienced a decline in the Great Lakes due to commercial fishing, habitat degradation and an invasion of non-native species such as invasive plankton, alewife, and zebra and quagga mussels. A top priority with Great Lakes managers has been to recover native species to provide a better balance in food-web structure and function.

With the new addition, hatchery biologists will have the ability to recirculate at least 90 percent of the water. The building will be equipped with an incubation system, 12 circular tanks for fry and two rectangular tanks for juvenile and adult fish. Supply water will be fresh well water from the hatchery. In addition, there will be a drum filter, UV treatment system, injectable oxygen, and water temperature control systems for incubation of eggs and larvae and rearing of and quarantining of the new arrivals.
