Restoring an Ancient Legacy Continues

 In June 2019 hatchery staff, Doug Aloisi and Orey Eckes, aided with the collection of lake sturgeon eggs from wild caught spawning fish below the NYPA dam in Massena, NY. After fertilization, eggs were transported to GNFH and DEC Oneida Hatchery. Sturgeon were fed diets of brine shrimp, bloodworms and krill until they were 7 inches long by the beginning of October. All sturgeon from GNFH were coded wire tagged, which gives them a batch identification number, allowing resource managers to assess future population growth and survival. By mid-October sturgeon were ready to make their journey back east. In October 2019 hatchery staff ventured out east with approximately 18,000 tagged lake sturgeon. Upon arrival they were welcomed by local press representatives and staff from USFWS-NYFO, DEC, SMRT, NYPA and USGS. The sturgeon were released into the St. Lawrence River at Ogdensburg and below the NYPA dam in Massena, as well as several larger tributaries. With this cooperative effort among agencies, biologist are hopeful populations of lake sturgeon in the St. Lawrence River may one-day return to historic numbers. Since 2013 when the partnership began 87,500 juvenile lake sturgeon have been stocked. The Genoa staff are looking forward to working with these partners for years to come to establish a growing tradition toward the restoration of lake sturgeon to the St. Lawrence River.

Visitors from Yellowstone are Making Themselves at Home

The Genoa National Fish Hatchery (NFH) have some visitors that are making themselves right at home. In fact, they like southwest Wisconsin so much that they don’t plan to leave for at least 16-18 months. That is if all goes as planned and they clear their 3 fish health exams and are able to visit other exotic places such as the Iron River (WI) National Fish Hatchery and Sullivan’s Creek (MI) National Fish Hatchery. There they will be incorporated into the Fish and Wildlife Service’s long range effort of restoring lake trout to the upper Great Lakes. The reason why we are so interested in having these visitors from Wyoming come stay with us is that many decades ago, lake trout from Lake Michigan were stocked into Lewis Lake in Yellowstone National Park. These fish, even though stocked generations ago still should maintain a cadre of genetics that was developed over time to survive in Lake Michigan. This genetic refugia is doubly valuable, as nearly all of the native lake
trout in Lake Michigan disappeared due to the effects of pollution, overharvest and the introduction of the parasitic sea lamprey into the Great Lakes. The Service has developed this Lewis Lake strain into a captive broodstock and egg source in order to use in their re-stocking efforts. Biologists from Iron River NFH and the Jordan River (MI) NFH with the Lander (WY) Fish and Wildlife Conservation Office captured adults from Lewis Lake and collected eggs from 150 pairs of adults and shipped them to Genoa’s quarantine facility. The eggs are being carefully cared for and equal numbers from each egg take will be used to make 2 lots of broodstock. The lots will be housed in Genoa’s quarantine facility until they clear 3 separate fish health inspections. Then they will be transported to the Service’s captive broodstock stations and the 2 lots will then be crossed with one
another. This is to reduce any chance of interbreeding with other closely related fish. Careful managementshould preserve the genetic diversity of the brood line and also ensure a fighting chance of survival once the yearling fish are released. Great progress has been seen in Lake Huron and Lake Superior in developing self sustaining lake trout populations, and with this native strain of lake trout available for stocking in, it is hoped that we may someday see the same results in Lake Michigan.

The Great Exchange

As the leaves begin to fall, the ponds at Genoa National Fish Hatchery begin to drain and the dragonfly larvae lose their summer home! During the summer months, the Hine’s emerald dragonfly larvae spend their time in cages in the hatchery ponds, eating all the zooplankton that swim by and are small enough for them to catch. As the temperatures cool, the station begins to drain the ponds to stock out the fish. This fall, hatchery staff met folks from the University of South Dakota just off the highway to transfer the larvae and in turn, received over 800 eggs. The larvae will be cooled down to go dormant over the winter and then next spring, USD staff will place them in cages near their future release sites to prepare for eventual emergence. Once back on station at the hatchery, the eggs were also chilled down and placed in the station’s large industrial cooler where fish feed is stored. The eggs will be monitored throughout the winter to check for any early hatches or fungus issues and water will be changed out periodically. By: Angela Baran Dagendesh

Jeni and a lake sturgeon in a river/USFWS.

Jeni grew up on the banks of the Missouri River climbing trees, hunting mushrooms, finding out where that great horned owl was sleeping and fixing up scratches, bruises and cuts for any wild kid or animal in the neighborhood. She studied biology and fish health at the University of South Dakota, then moved to the University of Wisconsin-La Crosse in 2001 for work on a master’s in fish parasitology. She started work at the La Crosse Fish Health Center in October the same year. After experiences including lake trout restoration at Pendills Creek National Fish Hatchery and work on lake sturgeon, fresh water mussel and sportfish recovery at Genoa National Fish Hatchery, she moved back to the La Crosse Fish Health Center in 2012 to help build the new Whitney Genetics Lab and eDNA program. Today you will find her in the La Crosse Fish Health Center’s flow cytometry lab working on new technologies for invasive species and fish health management, performing fish health inspections at Federal and Tribal fish hatcheries, sampling fish for the National Wild Fish Health Survey, or serving as Region 3 Study Monitor for the National Investigational New Animal Drug Program. Developing new technologies for conservation management is an exciting challenge. Working with the Service’s many great partners to provide the healthiest fish and aquatic wildlife for conservation is the most rewarding part of the job.

A Biologist Goes West!

This summer a call for help went out from Region 6 for the Jones Hole National Fish Hatchery in Vernal, Utah. The station had experienced a couple of retirements and their biological technician stepped up as a biologist at a new station, leaving Jones Hole with only a fish biologist, a term biological technician and seasonal fish technician for an extended period of time while they were waiting for positions to fill. During the summer months, they received help from a project leader out in Region 1 and I was able to fill in for 4 weeks. The detail provided experience at a new station, learning new species, new systems and tested troubleshooting skills! The remote station is located 40 miles, over 1 hour of driving time, from Vernal, Utah, 1 mile north of Dinosaur National Monument and less than a half mile from the Colorado border. The station is complicated not only by the remote location, but also by the maintenance workload they have, and the federal partners surrounding the hatchery, (National Park Service and the Bureau of Land Management). Because of the location, the hatchery is responsible for all of the electrical service once it reaches the outskirts of the station, the transformers, the powerlines and poles. If there are any issues, they first have to figure out if it is with the station services or the electric company, sometimes requiring the repair crews of both the electric company and then a private high voltage company to determine the issue and how to resolve it. In addition to the power responsibilities, they maintain 13 miles of the road leading to the hatchery, guardrails, pavement and snow removal… which in the mountains in the winter can be a full time job for a crew just to open the road back up to get out. The time on station shifted from my comfortable fish and mussel rearing skill set to managing larger issues for contracting and station maintenance, where small issues like a door repair are further complicated by trying to find a company willing to drive an hour to complete a smaller job. The initial thought of being on station for 4 weeks seemed like a long time to be able to accomplish things so a list was developed working with the staff. By the end of the second week, that focus had to shift from adding to the list to prioritizing items that could be completed or set in motion before the end of the detail. It seemed as if I just blinked and the time was done! The whole experience was invaluable and I thoroughly enjoyed the time out west, but it was still good to return home to the staff, fish, mussels and dragonflies at Genoa. By Angela Baran Dagendesh

Pond Research Yields Bountiful Harvest

As fall is upon us, the growing season for fish and mussels are quickly coming to a close. This is when ponds at Genoa National Fish Hatchery (NFH) are drained and fish and mussel are either placed in their winter homes for continued grow out at the hatchery, or released into their wild habitats. This season the staff at Genoa were trying to determine the best water quality and fertilization schemes to rear both fish and freshwater mussels in 2 hatchery ponds. 24 hour monitoring equipment was acquired and 2 seasonal employees were tasked with taking daily and weekly water quality measurements. Our mussel biologists, Megan and Beth also pitched in and took measurements of food particles throughout the growing season. In early June largemouth bass with Fat Mucket (Lampsilis siliquoidia) mussel larvae attached to their gills were placed in propagation cages in two similar sized ponds. Ponds were fertilized weekly dependent on healthy water quality parameters. This week the ponds were harvested and cages were carefully checked for mussels. The three + month old mussels could be hard to find but with the help of the Prairie du Chien Advanced Placement High School Biology class, partners from the Iowa DNR and some of our trusted volunteers the harvest was bountiful. Over 35,400 juvenile Fat Muckets were removed from the cages and began to be distributed for further grow out this winter. This is exciting news for us as rearing mussels co-located in fish ponds would save us many hours of transportation. It would also save us the uncertainty of uncontrollable variables such as high water and cage siltation in the natural environment. We still have yet to try these methods on other species that may have more challenging culture and water quality requirements but are optimistic that results are repeatable with careful pond monitoring and course corrections throughout the growing season with other species and host fish requirements.

Pond Harvest in Full Swing

Pond Harvest is in full swing at Genoa NFH. We had 18 ponds involved in production this season to fulfill our distribution and mussel host goals. Species raised in the pond program include Smallmouth Bass, Largemouth Bass, Yellow Perch, Walleye, Bluegill, Black Crappie, Channel Catfish, Golden Shiner, and Fathead Minnow. These fish head out all over the Midwest to federal and tribal waters. We have even had enough surplus to provide fish to our state partners and stock the Mississippi River right here at home with some Bluegills, Largemouth Bass, and Walleye. We hope to have harvesting completed by the end of October! By: Nicholas Bloomfield


Beka is a fish biologist with the La Crosse Fish Health Center. She earned her Bachelor’s degree in Conservation Biology from UW-Madison and her Master’s degree in Aquatic Science from the UW-La Crosse while working as a SCEP student at the lab. Her previous work experience includes behavioral research with non-human primates at the UW-Madison, work as a veterinary technician at several animal clinics, a job as a laboratory technician at a biopharmaceutical company, and working in the microbiology department of a human clinical lab. Upon graduating from UW- La Crosse in 2012, she was converted to a permanent position and now enjoys her work as a biologist because it allows for a nice balance of both lab and field work. Her main duties include working in several different labs to screen hatchery-reared and wild-caught fish for viral and bacterial pathogens and parasites, participating in wild fish surveys, and traveling to national and tribal fish hatcheries within Region 3. In her free time, Beka enjoys traveling, hiking, kayaking, camping, cooking, and road tripping to seek out the country’s best craft breweries with her husband, Ed, and golden retriever, Finn.



Corey is a fish biologist with the La Crosse Fish Health Center. He graduated from University of Wisconsin Stevens Point with a degree in Water Resources/Fisheries and Limnology. He performs a wide range of lab work including virology, bacteriology and parasitiology. He also coordinates with our many federal, state and tribal partners to schedule fish health samples, fish health inspections, wild fish samples and fish diagnostic cases /USFWS.


When she was a child, Ellen wanted to grow up to be an explorer and naturalist – and sometimes she also wanted to be a veterinarian! In veterinary school at Mississippi State University, she pursued an interest in charismatic mini-fauna such as fish and amphibians (while her classmates were pursuing charismatic mega-fauna). While getting her Ph.D. at the University of Montana, her interests focused on charismatic micro-faunal communities (bacterial microbiomes). So it should be no surprise that she joined the La Crosse Fish Health Center in 2017 as their Veterinary Medical Officer. In addition to looking at and treating health issues in fish, Ellen investigates health issues affecting the fish microbiome. She greatly enjoys the opportunity to explore these two very different aspects of fish health and ecological health at her job. In her spare time, she enjoys x-country skiing, hiking, gardening, cooking and reading science fiction. Photo: Ellen Lark/USFWS.
