Summer is here and the Hine’s emerald dragonfly larvae arrived on station May 30th, hand delivered by the University of South Dakota (USD) staff and students attending the Captive Rearing and Augmentation Work Group meeting at Genoa National Fish Hatchery, (NFH). Genoa NFH began working with the dragonflies in 2015 after receiving funds through the Cooperative Recovery Initiative Grant, allowing the station to purchase equipment, build a mobile rearing unit and hire temporary staff. Over the last four years, the program has grown to include the Forest Preserve District of DuPage County, Brookfield Zoo and the Illinois Department of Natural Resources. This working group has established restored habitat in some of the Forest Preserves as well as creating new captive rearing locations, allowing increased production. Through the collaborative process, all parties are beginning to share information about new rearing techniques or how they have handled any complications so the program as a whole is growing and the larvae are receiving the best care possible.

This summer the station received larvae on May 30th and placed them into cages in the mobile rearing unit on May 31st. This mobile rearing unit allows the larvae to be in a highly visible tank to monitor the small larvae closely during the first couple weeks on station as well as serving as a temporary quarantine facility, keeping the larvae in an isolated water source. The mobile unit was designed to use pond water, drawing from the pump station it is located next to. This source water coming from the ponds is full of natural food sources for the larvae, teeming with zooplankton to eat and is also at the ideal rearing temperature for the larvae. Water conditions were ideal early summer and the larvae grew enough to be moved to larger cages out in one of the hatchery ponds on June 22, 2019. The cages will be checked periodically throughout the summer to monitor the larval growth and the ponds are monitored daily for oxygen levels and temperature. At the end of the summer, the larvae will be weighed and measured again and then transferred back to USD for final larval growth and eventual emergence in 2020.

Sturgeon Pen Pals: Connecting Wisconsin Students with their Lake sturgeon

Posted on by

BY GRETCHEN NEWBERRY, MIDWEST FISHERIES CENTER

It started with a question: How many students along the Mississippi River would be able to recognize a lake sturgeon? In the Driftless Area of southwestern Wisconsin, kids are often exposed to the outdoors. It’s a rolling landscape of streams, wetlands, bluffs, prairies and caves, and many students fish with their parents and grandparents, sometimes from their own backyard. But, what about the fish that don’t end up on their hook? How much do they know about fish that are less common?

The Midwest Fisheries Center has a long history with lake sturgeon conservation. Since the 1990s, the center’s biologists have worked with tribes on restoring and monitoring lake sturgeon populations. Helping young people become more knowledgeable about lake sturgeon conservation increases public awareness promotes the value of this work.

Taking the lake sturgeon into the classroom and telling their story to the students could only help. At West Salem Elementary School’s Environmental Day this last spring, I asked the students if they thought lake sturgeon lived in Wisconsin. Among six classrooms of 20 children, only half of the students were certain lake sturgeon could be found in the state, and only a couple students could identify the sturgeon in our tank.

The students were led through a series of questions to introduce them to this charismatic fish: How many of you have ever wanted to see an animal that has lived alongside a dinosaur? How big do you think a lake sturgeon can grow? How long can they live? Rather than presenting the facts, asking questions engages students and gives them ownership of their own educational process. We talked about the 19th Century caviar craze that led to near extirpation for the lake sturgeon in Wisconsin, and how we, the Wisconsin people, brought their fish back from the brink. We talked about the cultural importance of lake sturgeon for First Nations people and how spawning sturgeon was a gift at the end of a hard Wisconsin winter long before there were grocery stores to help us all survive. They witnessed the Menominee Tribe’s fish dance via a video provided by the Wisconsin First Nations. We talked about the bumpy scutes that help young vulnerable sturgeon survive, their cartilaginous skeletons, and the importance of fish passage. All of these details helped the students flesh out the story of lake sturgeon and their own place in its history.

Al Brinkman, Midwest Fisheries Center and Genoa National Fish Hatchery (NFH) volunteer, and member of the Friends of the Upper Mississippi, talked to the students about his work coded wire tagging thousands of sturgeon at Genoa NFH last summer. It was important the students understood that sturgeon persist in this state and others due to civic engagement from the Wisconsin people.

The session ended by asking the students to help me out. I wanted to wish the sturgeon a good journey as they migrate our waterways and as they travel to other states to be released by our hatcheries. I asked the students to write postcards to the sturgeon as they contemplated what these young sturgeon need to survive.

More than 3,000 people connected with hatchery staff at outreach events and school trips this spring, including more than 1,900 kids! Staff traveled to 9 outreach events at schools, museums, and nature centers conducting programs on mussels, fish, and other aquatic organisms. On station, staff hosted 21 school field trips ranging in age from pre-school to college. Students toured hatchery facilities, explored the Great River Road Interpretive Center, and some groups had the unique opportunity to view fish relocation operations. A highlight from this season includes Kids Spring Fishing Day on May 18, 2019, where close to 250 people joined hatchery staff and volunteers for a day of fishing fun. 136 children first walked through a set of 4 learning stations. After an hour of learning more about fish and conservation, the kids were allowed to put their newfound knowledge to practical use with a 2 hour open fishing event on a stocked hatchery pond. Most children went home with their five fish limit. A light lunch was provided by our Friends group, and many door prizes were distributed thanks to local area vendors supporting the event. Many thanks to the staff, sponsors, volunteers, and Friends of the Upper Mississippi for making this event possible.
Are you interested in bringing your group to the hatchery? Contact the hatchery Environmental Education Specialist, Raena Parsons, for more information. Raena_Parsons@fws.gov or 608-689-2605.

Pond Production Season Begins at GNFH

Posted on by

Pond production season is in full swing at Genoa NFH. As a new employee at the hatchery, I’m making my first journey through the annual cycle. I was promised it would be busy and hectic at times, and I haven’t been disappointed. We kicked off the season dividing bloodstock out from their overwintering ponds. The Yellow Perch are the first to take action. We barely got them into their pond in time from the overwintering pond, with eggs and milt running from the fish as they were going into the pond. These will be ready to be harvested in mid-June and sent to their new homes in several state and federal waters. Walleye were next. Once fry were hatched from the egg battery, four production ponds were stocked with around 100,000 fry each towards the end of April. Since then, we have focused on water quality and zooplankton production to start growing these guys up. Phase 1 harvest is underway as of this writing. From there, ponds will be re-stocked at new rates, with any surplus going to state and tribal partners. As waters have warmed, Largemouth Bass, Smallmouth Bass, Bluegill, and Black Crappie have started to do their thing. About 16,000 Smallmouth Bass fry were pulled from the nests in the end of May and restocked into 2 ponds to continue grow out. Soon, it will be time to conduct the phase 1 harvest on the others and divvy them to their new ponds to continue growing. As I take my first trip through a production season, I continue to learn something new every day. I can’t help but ponder the future for these fish. Some may find their way onto somebody’s fishing line and provide a meal or a smile. Some might produce the offspring that somebody catches years down the road. Fun to think about the possibilities!

Thanks for your help at 2019 Kids Fishing Day!

Posted on by
All,
Thanks very much for volunteering your time, resources and passion for the outdoors this past weekend at the 2019 Kids Fishing Day at the Genoa hatchery.  Even with all of the activities ongoing in the area and the threat of bad weather, we had 248 people attend, with 136 of those being our target audience, children ages 5-12.  The rain held off for most of the event, and everyone went home with a fish, and many with their limit of 5.  Please find a few pictures of some happy attendees.
Thanks again for your efforts to create a culture of outdoor recreation and conservation in our community and the next generation of conservation stewards.

Walleye Egg Hatch Continues to Improve at Genoa NFH

Posted on by

 BY OREY ECKES, GENOA NFH

Over the last few months, hatchery staff members have been finalizing additional renovations of the holding house from the 2018 walleye production season. Due to increased demand for more walleye eggs from state, tribal and federal partners, the hatchery had increased holding and hatching capacity for walleye eggs and fry in 2018. The modifications of hatching tanks and rearing space allowed the hatchery to collect nearly 70 million walleye and sauger eggs from the Upper Mississippi River for stocking in the spring of 2018.

Upgrades and renovations consisted of: A new aluminum head tank that was installed allowed for a larger available water volume to supply fish rearing tanks, increased particulate settling time and improved oxygenation. New oxygen lines had also been added to improve delivery of oxygen, create more working space, and allow for easier access to the oxygen supply tanks. Maintenance staff member, Jeff Lockington fabricated and installed egg incubation tanks and fry hatching tanks.

The new egg incubation setup allowed for incubation of over 60 million walleye eggs. Zach Kumlin, also a part of the Genoa National Fish Hatchery (NFH) maintenance team, installed flow meters wired to a control box (PLC) to allow biologists to review and manipulate flows for walleye egg treatments. He also installed a peristaltic pump for chemical treatment of eggs to reduce loss of eggs from fungus.

In 2019, staff members are hard at work installing a larger pump to increase water volume and are incorporating a sand filter into the system to remove particulates such as iron, which bind to eggs and newly hatching fry. These new modifications for 2019 will help increase eye up percentages, resulting in better survival of eggs and newly hatched fry. This new setup will allow the hatchery to produce and stock more walleye for recovery and restoration efforts. Genoa NFH staff will be on the Upper Mississippi River this spring in an effort to collect enough walleye eggs to meet our partners’ requests.
