Edison Sault Electric Company is a longtime partner with Lake Superior State University (LSSU) and the Aquatic Research Laboratory (ARL) in promoting education, research and outreach. Now, Edison has donated a 16,000 square-foot, three-story building which will allow the ARL to nearly quintuple its present size and modernize its facilities to enhance undergraduate training and education at LSSU. Since the mid-1970s, Edison Sault, a subsidiary of Wisconsin Energy company since 1996, has provided space for LSSU's Aquatic Research Laboratory in the ARL Newsletter 2008 Volume 3, Issue 1 east end of its hydroelectric power plant. Through Edison's generosity, the ARL expanded over the years and has outgrown the available space. The donation will allow the ARL to add a number of facilities, including a visitor center and discovery room, given that the ARL already hosts approximately 1,000 visitors per year. In addition, the new building will include a fish health laboratory, classrooms, teaching and research labs, and space to allow the ARL to support collaborative projects with researchers outside LSSU. President Donald Sawruk of Edison Sault said the local area needs to help LSSU grow. "The ARL is a unique project because you have a business working hand-in-hand with a local university and that relationship turns out benefits both for students and the region," said Sawruk. LSSU's President, Dr. Rodney Lowman, noted that the work being done at the Aquatic Research Laboratory is an example of the fine "hands-on" training Lake State students receive. “Not only do we turn out fisheries and wildlife graduates who are in great demand,” said Dr. Lowman, “but the ARL also serves sport fishers who benefit from the Atlantic salmon we grow there. Our research on fish helps to prevent disease and improve the growth of fish in an ecologically sound way.” "This [new building] will allow us to add a hands(Continued on page 2) Page 1 ARL Highlights-For more information visit: www.lssu.edu/arl A Fish Tale Comes True Greil, who has managed the ARL for 18 years. "Edison has been a great partner over the years. They on facility to get our visitors more involved when they have always been there for us when we needed them, tour the lab," said Dr. Ashley Moerke. "It will let them and this is another example of the kind of support they spend more time in the lab when they visit, and it will have given us. We owe them a lot." give us a better ability to educate the community on what we're doing and why." The ARL offers the sort of "real-world" experience that LSSU prides itself on. It provides students with a variety of fish hatchery skills, research and monitoring experience, and support for their senior thesis research projects, all of which help them get jobs and placements in graduate schools. "Our current lab does include some research space, but we need to redesign the rooms for each project," added Dr. Geoffrey Steinhart. "With more dedicated lab space, we can support many student projects and collaborate with other agencies and universities much more easily." "We are very excited about this building and the opportunities it will open for us," commented Roger The future home of the ARL. Photo by D. Traynor. (Continued from page 1) Fish & Wildlife Club Lands Regional Award By Brandon Gerig (‘09) The LSSU Fish and Wildlife Club was honored with the Most Active Student Sub-unit of the American Fisheries Society, North-Central Division (NCD) Award. “Lake Superior State University stood out as the unanimous award winner among seven nominated Student Subunits” said NCD President Jessica Mistak. This was quite an accomplishment considering the club has only been an official subunit since December 2006. The LSSU chapter received the award for its commitment to professional development and community service. Featured events included participating in a lake sturgeon telemetry study, lake surveys on the Hiawatha Sportsmen’s Club and aiding in the maintenance of a Kids Fishing Pond in Sault Ste. Marie. Winning this award adds to LSSU’s reputation as one of the premier universities in the Midwest for Fisheries Management. Seventeen members of the LSSU Fisheries and Wildlife Club attended the 68th annual Midwest Fish and Wildlife Conference in Madison, Wisconsin to receive the award. Additionally, at the conference, four members of the club were selected to attend the Janice Lee Fenske Memorial Breakfast. The breakfast, which was by invite only, allowed exemplary students to engage professionals with questions regarding career and graduate school opportunities. The conference also was a valuable experience in which students learned about current research while making connections with natural resource professionals. Two students presented their research projects at the meeting. All students benefited from attending the meeting, and an LSSU Alumni Social, which allowed networking opportunities for graduate school, jobs and summer internships. Attending this meeting was definitely a highlight of the year for the club and we plan to continue a strong showing, representing LSSU well at future meetings.

Of the 45 species in Michigan, over one-third are listed as a species of concern, endangered, or threatened. Information on the status and distribution of these important animals is vital for future management decisions that would protect and preserve these delicate populations. During summer 2007, Fisheries and Wildlife students Jen Johnson and Kate Harriger were employed by Michigan Natural Features Inventory to survey freshwater mussels throughout the eastern Upper Peninsula of Michigan. This was the first time a scientific evaluation had been conducted for these imperiled animals in the Upper Peninsula. Initial thoughts were that freshwater mussel populations would be low, but it turned out to be quite the opposite. Several species were documented; most notably fat muckets (Lampsilis siliquoidea), cylindrical papershells (Anodontoides ferussacianus), and giant floaters (Pyganodon grandis). Surveys were conducted in of wadeable streams using glass bottom buckets in order locate mussels buried in the substrate. Survey sites were marked using GPS units and later imported into GIS software for further analysis. Jen recently finished her senior thesis which analyzed possible correlations between geology/land use and overall mussel populations.

Johnson. focusing on the distribution of mussels throughout Hannah Creek, a small tributary to the Carp River, and how it’s related to microhabitat and mussel age. Jen presented her final results at this year’s meeting of the Michigan Chapter of the American Fisheries Society. Jen also received the inaugural Sault Naturalist’s Best Senior Thesis Award, awarded for outstanding natural resource research at LSSU. Kate will be presenting her results at several conferences, including the 2008 Midwest Fish and Wildlife Conference.

ARL Newsletter 2008 Volume 3, Issue 1 Page 3 ARL Highlights-For more information visit: www.lssu.edu/arl Everything You Ever Wanted to Know About Atlantic Salmon, but Were Afraid to Ask By Jesse Kamps (‘09) Each year, hundreds to over a thousand Atlantic salmon (scientific name Salmo salar, meaning the salmon leaper) return to the St. Marys River and the Aquatic Research Laboratory, where they were hatched. Eggs are collected from these returning fish and raised in the hatchery. Each spring the ARL releases about 25,000 Atlantic salmon yearlings into the St. Marys River. Fish from the ARL travel throughout the Great Lakes and have been caught in every Great Lake from Lake Superior to Lake Ontario. Every fall, our salmon journey up the St. Marys River to spawn, returning directly below the hatchery. The fish are attracted to the flow and odor of the discharge water from the ARL’s hatchery. When the water temperature reaches 10°C, students start collecting Atlantic salmon and taking records for our research. The length, weight, and sex of each fish are recorded, along with the number of sea lamprey scars. Fish also are checked for fin clips, allowing the fish to be aged (see How Old is My Catch? on page 5). After all records are taken for each fish, they are placed into sex-specific holding containers where they remain (for up to two weeks) until they are sexually “Stripping” eggs (left) and milt (right) from Atlantic salmon.

Lunn. mature or “ripe.” When the Atlantics are ripe, they are sedated to reduce stress. A female is stripped of eggs by applying gentle pressure on the abdomen. Eggs are stripped into a bucket where they will await the milt. Males are stripped of milt in much the same fashion. The milt and eggs are then mixed together and water is added in order to start the fertilization process. Samples of both eggs and milt are taken and tested for diseases before any eggs from different pairings are mixed together. Fertilized eggs are cleaned with an iodine solution, to remove any bacteria that may compromise the eggs. Disinfected eggs are then placed into individual containers until results of the disease testing come back. Eggs from parents that test positive for bacterial kidney disease (BKD) are discarded. Healthy eggs are placed into eggs trays and are ready for rearing. Eggs also are tested for early mortality syndrome (EMS, a vitamin B deficiency) and all eggs are treated with a vitamin B bath to stave off this damaging deficiency. The young fish stay at the ARL for about a year and a half and are released in May or June at a size ranging from 6-12.” From there, we wait for their return in one to three years.

Each year-class of Atlantic salmon receives a different fin clip to identify which fish are returning. If you hold the fish upright, with the head away from you, the fish’s right fins are on your right, and the left fins on your left. In 2008, you might catch Atlantic salmon of any year-class from 2004-2008 (see table below). Year Class Fin Clip Age in 2008 Average Length 2008 2007 Right ventral Right pectoral 1 year 2 years < 15 in 22 in 2006 Left ventral 3 years 28 in 2005 Left pectoral 4 years > 28 in 2004 Right ventral 5 years > 28 in Characteristics of different Atlantic salmon year classes in the St. Marys River during 2008.

The St. Marys River supports world-class Atlantic salmon fishing. What makes the St. Marys so special? “What is most unique about our Atlantics is that they aggressively feed in the river, unlike many Atlantic salmon on the east coast,” says local fishing guide John Giuliani. Indeed, from May through late August, Atlantics in the St. Marys aggressively feed on the abundant prey fish. Once spawning starts, Atlantics will still bite out of instinct and aggression. Some Atlantics are caught all winter long in the St. Marys River rapids. Tips from local guide John Giuliani (www.worldsites.net/riverfishing): • Atlantics attack schools of smelt at the surface—look for bird activity or splashes to find the fish. • Troll minnow patterns (flies or spoons) at the surface in front of the hydroelectric plants during summer. • Cast minnow patterns in the rapids (accessible only from the Canadian side, Ontario license required). • Atlantics can be caught near DeTour, MI from mid-May through July, near Sault Ste. Marie, from midJune through July. Fishing off the docks or near the St. Marys River rapids is good through August. News and Notes: • LSSU has added a new Bachelor’s of Science degree in Fish Health. This degree will train the next genera- tion of fish pathologists for agencies, zoos, and hatcheries.

By Corey Jerome (‘09) Eurasian watermilfoil is an invasive species introduced into the United States in the 1940s. Watermilfoil has become a large problem within many inland lakes because of its ability to form a dense surface canopy and out-compete native plants. This nuisance aquatic weed limits recreation abilities by impeding boating traffic and other water recreation. Because of problems caused by watermilfoil, lake associations and conservation agencies have been looking into ways to control the aquatic plant. One possible control agent is the milfoil weevil. This native aquatic insect eats the plant and lays its eggs in the stems of Eurasian watermilfoil. Weevil larvae damage the stem, which halts nutrient movement throughout plant. As weevils damage the plant, it causes the milfoil to sink out of the water column. Weevils can multiply quickly: within a typical growing season, weevils are able to complete three generations. Therefore, weevils are a good candidate for the control of the milfoil because they can be self sustaining after the first planting. An unknown factor I am studying for my senior thesis is the predation on the weevil by panfish. Panfish are known to forage within weed beds and may feed on milfoil weevils. Agencies are concerned that panfish predation on weevils may limit weevil populations to where they will not be able to control Eurasian water milfoil.

LSSU hosted the annual meeting of the Michigan Chapter of the American Fisheries Society on 3-5 March, 2008. It was the first time the meeting has been held at LSSU and it has been over a decade that MIAFS last convened in the Upper Peninsula. Three LSSU students and two faculty presented talks on their research. Another seven LSSU undergraduates presented research posters. In the end, LSSU won both the best student presentation awards. Scott Collins (‘08) won the best student presentation award for his research on how Pacific salmon effect stream communities. Ryan Namespetra (‘08) won the best poster award for his research on sea lamprey control techniques. “The AFS meeting was a great way to meet people and inform them about your research,” said Ryan. “I feel that the senior thesis process was very helpful in understanding research techniques.” Seventy-six people attended the meeting which included 21 oral presentations and eight posters. For the first time in many years, there were concurrent sessions for oral presentations and the meeting was well received by MIAFS members. The plenary speaker was Dr. Paul Seelbach (Institute for Fisheries Research (IFR), Michigan Department of Natural Resources (MDNR)) spoke of Michigan’s proposed water withdrawal assessment process and water management policy. Dr. Kevin Wehrly (IFR, MDNR) led a workshop on non-gamefish identification that was so popular we had to cap enrollment at 30 participants. The meeting not only highlighted current research, but also gave LSSU students, faculty, and staff a chance to highlight Ryan Namespetra (‘08) presents his award winning poster on sea lamprey repellents.
