Fisheries, Midwest Region Conserving America's Fisheries First Stocking of Lake Sturgeon into the Maumee River Scheduled for October 2018 BY OREY ECKES, GENOA NFH Genoa National Fish Hatchery (NFH) recently joined a multi-agency effort to reintroduce lake sturgeon to the Maumee River, Ohio a tributary of Lake Erie. The hatchery will provide intensively cultured lake sturgeon for the stocking effort. The partners include the Toledo Zoo, U.S. Fish and Wildlife Service, U.S. Geological Survey, Ohio Department of Natural Resources (DNR), Michigan DNR, University of Toledo and Ontario Ministry of Natural Resources and Forestry. Historically populations of lake sturgeon were abundant in the river; however they are no longer present. Research has shown that the Maumee River is a strong candidate for lake sturgeon reintroduction, providing suitable habitat for spawning adults and offspring. The Southern Lake Huron (Upper St. Clair River) population will be used as donor stock for this study. Recently lake sturgeon have been cultured in stream side rearing facilities in multiple locations along rivers that are Great Lakes tributaries to allow for sturgeon to imprint on natal Lake sturgeon being raised at Genoa NFH for stocking into the Maumee River, water, with the hope of increasing site fidelity as a OH.

A sturgeon trailer was deployed near the Toledo Zoo to raise 1500 lake sturgeon on Maumee River water and Genoa NFH is raising 1500 lake sturgeon on hatchery water supply. Once fish are eight to ten inches at both locations they will be tagged with a PIT (passive integrated transponder) tag to monitor future growth and survival. This project calls for paired releases of sturgeon from both locations for 25 years to reach a target self- sustaining population. Adult returns to the river from the stocked population will be monitored to see if sturgeon cultured in a streamside rearing facility exhibit higher stocking site fidelity rates vs. fish cultured at offsite locations (Genoa NFH). In addition, researchers will assess post stocking survival rates between sturgeon cultured in a streamside facility and sturgeon reared in a traditional hatchery. Also, the streamside trailer located on the Maumee River (Toledo Zoo) property will serve as an exceptional place to engage the public in lake sturgeon restoration. The Toledo Zoo will be incorporating lake sturgeon restoration and the streamside trailer into one of the exhibits open Lake sturgeon being raised at Genoa NFH for stocking into the Maumee River, OH.

Now retired biologist Bob Vande Kopple, one of the few HCWB experts in the world, taught the group about the life history, identification, and survey techniques for the rare beetle that is only found in a few watersheds in Northern Michigan and Canada. HCWB most often occur in moderate to fast flowing alkaline streams that have good aeration and inorganic substrates. They can be found in a variety of water depths ranging from only a few inches to a few feet. They are often found in plunge pools created from debris jams (beaver or natural), man- made dams or culverts, and well aerated natural riffles. Hungerford's Crawling Water Beetle.

This workshop provided opportunities for us and our partners to learn more about existing HCWB populations, locate new populations, and help the endangered beetle on a path to recovery. The National Fish Passage Program has undertaken many projects throughout watersheds containing HCWB. Each project shows us how valuable installing properly sized culverts, removing dams, and replacing failing infrastructure can be in directly benefiting many target fish species and indirectly benefitting all Looking for individuals in a known population of HCWB.

Lindsey Adams, USFWS Projects completed near known HCWB populations have proven that these little beetles are extremely resilient and respond very well post-construction, thus showing the need to continue doing these projects.

This species is native to the southern United States and northeastern Mexico, but has been introduced to every continent except Antarctica and Oceania (i.e., Australia, Melanesia, Micronesia, and Polynesia) – thus, they are considered the most cosmopolitan freshwater crayfish species in the world. Red swamp crayfish have a high commercial value in the food industry (especially live), representing hundreds of millions of dollars annually in Louisiana alone. They also are sold by biological supply companies for use in science classrooms and for research purposes. The main vector of introduction is the transport, and subsequent release, of live individuals from the wild- capture fishery and aquaculture facilities, but red swamp crayfish also possess several characteristics that make them successful invaders. This species can colonize a wide variety of habitats (e.g., rivers, lakes, streams, canals, seasonally flooded swamps Red swamp crayfish. Credit USFWS and marshes) with varying environmental conditions (i.e., salinity, pH, oxygen, and temperature), and also exhibit rapid growth, short development time, and a flexible feeding strategy (i.e., omnivory). Red swamp crayfish can also quickly spread to adjacent habitats because they exhibit a “wandering” phase, dispersing up to 10 miles in four days. Once established, red swamp crayfish have the potential to cause ecological harm through competition with native crayfishes for food, erosion of shorelines through extensive burrowing habits, and up- rooting of native aquatic plants. Currently, little information is known about the distribution of red swamp crayfish across the Great Lakes region. To the best of our knowledge, only a few documented populations exist in states surrounding Lake Michigan and targeted sampling for these species has been limited. The spread of these small populations appears limited so far, which has allowed agencies to attempt control and management efforts. For example, the Wisconsin Department of Natural Resources has spent considerable effort trying to eradicate red swamp crayfish from a couple small retention ponds. Red swamp crayfish survived (likley in their burrows) a water drawdown and bleach treatment and separate treatment with a chemical that alters nerve function. Finally, they were eradicated by destroying their burrows by excavating the shoreline and then the ponds were completely filled in and capped with gravel. Preparing to set baited minnow traps. Credit: USFWS In 2018, Green Bay Fish and Wildlife Conservation Office (FWCO) – Aquatic Invasive Species staff realized an opportunity to use their resources to initiate a collaborative, multi-state monitoring study to better understand red swamp crayfish distribution (presence or absence) in high-risk Lake Michigan waters and connected waterways in Illinois (IL) and Indiana. We partnered with researchers at Loyola University – Chicago who are currently studying red swamp crayfish in the Chicago River. Nine hundred minnow traps (baited with cereal dog food) were used to sample interconnected waters across approximately 45 miles of the greater Chicago area. One new population of red swamp crayfish was discovered in Jackson Lagoon near Chicago, IL which is directly connected to Lake Michigan and adjacent to Jackson Harbor. In total, 17 red swamp crayfish (seven females and ten males), representing multiple age classes were captured in Jackson Lagoon. Next year, we likely will expand monitoring to include high-risk areas in Wisconsin and Michigan. Once completed, this comprehensive distribution information will aid in management and control efforts for red swamp crayfish in Lake Michigan and adjacent waterways.
