Rainbows Depart for Warmer Pastures

 

You don’t see too many rainbows in Southwest Wisconsin in the middle of winter. That view is usually saved for thunderstorm season in the heat of the summer time. And if you were looking for a Rainbow this winter, you would find 8,000 less of them. That Rainbow, of course, is the Rainbow Trout, raised in Coulee Region of Southwest Wisconsin at the Genoa National Fish Hatchery. Due to some good quality eggs from the Ennis (MT) National Fish Hatchery, and good survival the hatchery was fortunate to have a surplus this year. It was fortuitous as our sister hatchery Neosho National Fish Hatchery in Missouri was limited in rearing space due to a construction project. The Neosho station found a weather window and sent two drivers up in December to pick up their new charges. 8,000 8 inch trout weighing a total of nearly 1800 pounds were loaded onto 2 trucks for the long 12 hour trek back to the Ozark Plateau of southern Missouri. Word back has it that they like southern Missouri just fine, and the 60 degree weather has sweetened their disposition and diet. They will be raised for roughly another 2 months and stocked as 11 inch fish in Lake Taneycomo, to mitigate for the federal water project of Table Rock Dam. The dam and its resulting deep cold water discharge eliminated a local smallmouth bass fishery below the water control structure. Rainbows like the cooler waters of the downstream Lake Taneycomo, and create a very popular fishery there. Plenty of Rainbows still remain in southwest Wisconsin, however. Plenty enough to brighten many fisherperson’s disposition and creels coming this spring for the trout season opener. Over 30,000 still await the spring trout season, when they should be 12 inch sticks of dynamite, just waiting to fight their way into a lucky creel. The trout will be used to create recreational fisheries on Midwestern tribal waters, in Fort McCoy Army base ponds, and also be used at Genoa’s kids fishing events, and limited accessibility fishing events.

Tracking Lake Sturgeon Release in Maumee River

 

 

 

 

 

As part of a multi-agency effort (Toledo Zoo, USFWS, USGS, Ohio DNR, Michigan DNR, University of Toledo and Ontario Ministry of Natural Resources and Forestry) lake sturgeon have been released for two consecutive years (as part of a 25-year stocking plan) into the Maumee River, a tributary of Lake Erie. A sturgeon trailer was deployed near the Toledo Zoo in 2018 to raise 1500 lake sturgeon on Maumee River water and for 1500 fish to be reared at Genoa National Fish Hatchery on hatchery supply water. To date 3,000 lake sturgeon have been stocked from the Genoa (WI) National Fish Hatchery. The project calls for paired releases of sturgeon from both locations for 25 years to reach a target self-sustaining population. Once fish are 6-8 inches at both locations, they are tagged with a PIT (passive integrated transponder) tag to monitor future growth, survival and adult returns during spawning. In addition, 40 fish from 2018 and 40 from 2019 were implanted with acoustic transmitters to track juvenile lake sturgeon movement, habitat use, and survival in the Maumee River and migration into Lake Erie. This data will be used to do address questions: 1) Do Lake Sturgeon reared in traditional or stream-side hatchery facilities show similar short-term survival rates after stocking? 2) Do juvenile Lake Sturgeon reared at traditional and stream-side facilities show similar post-release movement behaviors, and what type of habitat do juvenile Lake Sturgeon use after release? The acoustic transmitter project will go into 2020 to address these questions. To date sturgeon released in the Maumee River from both rearing locations (Toledo Zoo and Genoa) have made their way out to the western basin of Lake Erie. Also, an exciting bit of news just reached biologists this fall from a commercial fisherman operating in the western Lake Erie basin. He captured one of the stocked lake sturgeon from the 2018 year class. It had already reached a size of 18+ inches and after checking its PIT tag number, its origin was found to be from the Genoa facility. Pretty exciting news: a lake sturgeon travelled as egg from the east coast of Michigan (St. Clair River, to Wisconsin’s beautiful west coast as a larvae/fingerling (Genoa NFH) to juvenile release in the Maumee River, now traversing as a sub adult in the western basin of Lake Erie. One of our babies is growing up fast and making a name for itself! By: Orey Eckes

Freshwater mussels are host specific, not just any fish will do. Snuffbox, a federally endangered species of mussel, depend on Logperch, a large darter that can grow up to approximately six inches and is found across the Midwest to transform their larvae into juvenile mussels. This fall a biologist with the Columbia Environmental Research Center in Missouri let us know that he’d had a great year raising Logperch in his ponds and we were able to pick them up in November. Five hundred Logperch arrived on station and were moved into quarantine. Logperch are a favored fish species because they learn very quickly to associate food with people and are charming when they beg for their breakfast with their rostrums (noses) out of the water. The Logperch are here to act as hosts for Snuffbox collected from the Wolf river system in the late fall. The hatchery is hosting three female Snuffbox collected from the Wolf River for the winter. Biologists from the hatchery and Wisconsin DNR plan to infest the Logperch in the spring and then drop off and grow the juveniles for a couple of years before reintroducing the species back into Wolf River streams where the species has been extirpated.

Volunteers Answer the Call to Prepare Minnow Broodstock

We were able to finish up harvest of the Fathead Minnow pond in December. We brought in over 2.6 million minnows! Many of these went into overwintering ponds to sustain broodstock and future mussel host fish over the winter. We also brought some inside to be used for feeding other fish on station. Not all of these minnows are destined to be a meal for a bigger fish, however. Using a grader, which separates bigger fish from smaller ones, we set aside tens of thousands of the biggest minnows we had. These lucky ones will go back out to the pond in the spring, their only goal being to produce millions more for next year. Unfortunately, there are some unwanted friends lurking within. Brook Sticklebacks frequently infiltrate the minnow pond and reproduce themselves. They are not as desirable a meal for fish as Fatheads, and the reason why is hidden in their name. This is where the volunteers come in. With their help, we are able to go through every minnow that will go back into the minnow pond and remove the sticklebacks. Hopefully that action combined with a good winterkill in the pond will result in a better food source for 2020. We couldn’t do it without the help of our volunteers! By Nick Bloomfield

ICE FISHING DAY POSTPONED

Due to unsafe ice conditions on our ice fishing pond, we are going to have to postpone and possibly cancel the Kids Ice Fishing Day. We were hoping colder temperatures this week would have created enough ice, but we still have open water on our pond as of today. We suspect the high groundwater levels this fall have also contributed to the open water by allowing groundwater to infiltrate the pond inhibiting the ice forming. Stay tuned for updates, possible makeup dates would be the remaining Saturdays in February if the weather permits enough safe ice to form.

A cooperative effort among the U.S. Fish and Wildlife Service – New York Field Office (USFWS-NYFO), Genoa National Fish Hatchery (NFH), USFWS – New York State Department of Environmental Conservation (DEC), the St. Regis Mohawk Tribe (SRMT), the New York Power Authority (NYPA) and the U.S. Geological Survey (USGS) is leading to the restoration of lake sturgeon to the St. Lawrence River and its tributaries.

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 Genoa NFH and DEC Oneida Hatchery. Sturgeon were fed diets of brine shrimp, bloodworms and krill and were seven inches long by the beginning of October. All sturgeon from Genoa NFH 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, biologists 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 NFH 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.

All Hands on Deck for Long Term Research and Monitoring Work

Prior to the 2019 field season, Region 3 Fish and Wildlife Conservation Offices (FWCO)  were asked to assist with Asian carp work being conducted within the Illinois River. Great Lakes crews from Alpena, Michigan, Ashland and Green Bay, Wisconsin, along with Large River crews from Columbia, Missouri and La Crosse, Wisconsin, all worked together to complete electrofishing, as well as, hoop and mini-fyke net surveys throughout the field season. The surveys followed the Long Term Research and Monitoring (LTRM) protocol that has been a successful model for collecting fish community data in large Midwestern rivers for nearly 30 years. This LTRM sampling effort is used to better understand the impacts of invasive species on native fish communities, to help inform hydroacoustic surveys, to evaluate contracted commercial harvest of Asian carp, and to detect young-of year Asian carp.

This unique opportunity brought together field staff that normally wouldn’t interact. New friendships were forged, new skills learned, and staff received a first-hand look at the conditions at “ground zero” in the battle to keep Asian carp out of the Great Lakes. For many Great Lakes personnel, this was their first time actually seeing invasive Silver and Bighead Carp in the wild. Watching them jump behind the boat and boil from the water when electrofishing put the threat these fish pose to our Great Lakes into perspective, and galvanized our efforts to keep them from gaining a foothold in Lake Michigan and beyond. Crews traveled long distances and worked long days in the heat and humidity while dodging flying carp. Through the teamwork and the dedication of FWCO personnel, the sampling was completed safely, correctly, and on time. Thanks to all!

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.

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.
