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!

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

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.


Shedd Aquarium Nets Some Coaster Brook Trout for Native Fish Display

Since Genoa National Fish Hatchery (NFH) is centrally located, many Midwestern aquariums periodically contact us for fish for their exhibits to engage the public with. Through these exhibits, our conservation message is also relayed to the public, which helps us to complete our mission to engage the public to conserve and protect our nation’s fish and wildlife resources for the continuing benefit of the nation’s populace. We were able to do this again this spring by making available a net full of nine to ten inch coaster brook trout for display at the world renowned Shedd aquarium at Chicago, Illinois.

These fish were available because of our ongoing cooperative restoration efforts that include the waters of the Grand Portage tribe on the northern shore of Lake Superior in Minnesota. The Fish and Wildlife Service has been working with the Isle Royale National Park staff and the tribe since the mid 1990’s to return this popular sportfish to its formal prominence in eastern Lake Superior. Reservation waters receive 10,000 yearling brook trout from Genoa NFH annually.

Through these efforts and strict harvest limits along the north shore that were implemented by the Minnesota Department of Natural Resources, fall coaster brook trout surveys have indicated an increase in numbers for the recent decade. Good news for the American people, this popular sport fish and a beautiful native fish historically abundant in Lake Superior.

Lake Sturgeon Growth Project

Genoa National Fish Hatchery (NFH) has been committed since 1993 to the goal of restoring lake sturgeon to its native range. In order to do this in the most effective and economic manner, the hatchery initiated a multi-year study to examine differing water temperature regimes with respect to lake sturgeon growth and feed consumption. The over-arching goal of the study was to determine growth rates across a wide spectrum of water temperatures for lake sturgeon    in order to create population models to estimate final size at stocking.

By also researching growth and food consumption at four separate water temperatures, we are also constructing feeding tables across this range of temperatures in order to gauge feeding efficiency and be able to project feed ordering needs for the entire production season.

Our maintenance staff at the station constructed a culture system consisting of six research tanks that have the capability of maintaining two distinct temperature regimes at once using a mixing valve. The experiment was run over two rearing seasons to include four test temperatures.

Results are being written up this winter for submission into an aquaculture journal in order to further lake sturgeon aquaculture programs. Our hope is to allow sturgeon culturists to better plan their production year and measure growth and efficiencies.
Many thanks to the Genoa NFH staff for all of their efforts to collect and disseminate great data, and our maintenance staff for their creativity and talents in order to make this project possible.

Every fall tens of thousands of lake sturgeon depart their temporary home at the Genoa National Fish Hatchery (NFH) and begin their lives out in the wild, beginning the long process of maturing into 20 plus year old fish that are capable of reproducing on their own.  Lake sturgeon populations have been severely reduced throughout their native range the past century due to human influenced effects such as over harvest, dam construction blocking spawning   migrations, and degraded water quality. This year two far off restorations took hatchery crew over 500-1000 miles away in order to restore this intriguing species to two river systems within its native range. Genoa NFH was part of a cooperative effort to return lake sturgeon to the Maumee River, Ohio for the first time since they disappeared from the system in the mid 1900’s. This October, 2,400 fingerling lake sturgeon were transported the 9.5 hours to Toledo, Ohio where they were part of the first release ceremony in a cooperative release effort with the Toledo Zoo.
The fish were tagged with a PIT tag, or Passive Integrated Transponder tag, that transmits a unique tag number to an electronic reader when scanned, much the same as a tag that may be used to tag domestic house pets. They were then
released safely into the waters of the Maumee. The next week, over 12,000 fingerling lake sturgeon were transported over 1,000 miles away to assist the New York Department of Environmental Conservation’s sturgeon restoration efforts. This year the waters of New York benefited by having another year class of lake sturgeon to grow and thrive in the St. Lawrence River, New York and Lake Ontario watersheds. These multiple year restoration programs ensure that lake sturgeon population numbers and genetic diversity are at levels that can begin to rebuild populations naturally once these long lived species begin to multiply on their own again. In these instances, long range partnerships provide great dividends for natural resource conservation in two distant states.
