Aquatic Research Laboratory “Creating Partnerships in Water Resources” 650 W. Easterday Ave., Sault Ste. Marie, MI 49783 | 906-645-1949 | www.lssu.edu/arl Mission Statement: “The LSSU Aquatic Research Laboratory will combine education and research on aquatic biota and their associated habitats within the Great Lake Basin to serve the academic, scientific, and public communities.” LSSU Alums – Sturgeon Allies by Stefan Tucker ‘12 J ohn Bauman (‘05), Jason Lorenz (‘08), and Stefan Tucker (‘12) began their fisheries careers while attending LSSU and each graduated with a Bachelor’s degree in Fisheries and Wildlife Management. At LSSU they had the opportunity to work with and research a small, remnant population of Lake Sturgeon in the upper St. Marys River. Currently these three LSSU alumni find themselves working collaboratively, representing three different agencies, to restore a struggling population of Lake Sturgeon (Acipenser fulvescens) on the Kalamazoo River in southwest Michigan.

The current Lake Sturgeon population is said to be at < 1% of its historical abundance due to extreme overharvest and habitat fragmentation and degradation. These prehistoric giants of the Great Lakes can easily exceed 6 feet long and weigh over 100 pounds. Many aspects of the Lake Sturgeon’s life cycle are remarkable and a true testament to their struggle to persist.

CAT recently initiated a research project aimed at improving manipulation of Atlantic Salmon cells for improving cell culture methods and conditions. Cell culture and in vitro methods for salmon cells will provide important research tools with wide ranging applications in aquatic animal health and immunology, physiology, developmental biology, endocrinology, cell biology, and aquatic toxicology. One area of research is in the development of germ cell manipulation and transplantation, given their strong potential for uses in basic research, conservation and biotechnology applications. The focus at CAT has been on working out techniques for isolation of cells and evaluation of cell quality by testing cell potency. In late 2013, in a collaboration between CAT, Lake Superior State University’s ARL, and the Michigan DNR Fisheries Division, approximately 300 juvenile Atlantic Salmon were transported 2,500 miles to CAT’s research facility in San Diego, California, for tissue isolations and cell culture work. Shipments of LSSUs juvenile salmon to San Diego (via insulated air-shipped boxes) went very well, with > 99% survival following the transfer. Sex determination of LSSU Atlantic Salmon using a realtime PCR assay CTA’s Aquatic Research Facility (San Diego) After arrival in San Diego, the groups of salmon were fin-clipped, and DNA was isolated and screened by real-time PCR assay using a gender-specific marker to allow for sex determination and sorting of males and females into separate systems. Over the course of several months, male and female gonadal tissues were isolated, and methods for evaluating the cells were developed. The major focus has been development of micro-manipulation techniques for transfer of isolated germ cells into functional gonads as an indicator that the isolated cell retains potency and the ability to differentiate. Results to date, thanks to the efforts and assistance of the team at LSSU, are encouraging and indicate that significant progress has been made toward establishing germ cell culture methods in Atlantic Salmon.

Dr. Kapuscinski by Staff K evin Kapuscinski began working for LSSU in July as Co-director of the ARL, and as an Assistant Professor in the School of Biological Sciences in August. where he will be teaching Ichthyology, Fisheries Management, Freshwater Fish Culture, and Fish Ecology at LSSU. In addition to his teaching and research interests, Dr. Kapuscinski is an associate editor of the North American Journal of Fisheries Management. Prior to coming to LSSU, Dr. Kapuscinski earned B.S. degrees in Biology and Water Resources (Fisheries) from the University of Wisconsin at Stevens Point, and then worked as a fisheries biologist for the states of Montana and Wisconsin. While in Montana, he worked to recover populations of Pallid Sturgeon, a federally endangered species. In Wisconsin, he had various job responsibilities but was especially active in efforts to reintroduce Muskellunge to Green Bay, Lake Michigan. In 2006, Dr. Kapuscinski left Wisconsin to pursue his Ph.D. in ecology at the State University of New York at Syracuse, and then worked as an Adjunct Professor conducting research on the Niagara and St. Lawrence rivers. Although some of Dr. Kapuscinski’s research in New York is still ongoing, he is getting involved in the ARL’s research on understanding the influence of tributaries to Whitefish Bay, Lake Superior, and is looking forward to developing additional projects in the region. Dr. Kevin Kapuscinski joins the faculty at LSSU as an Assistant Professor and Co-director of the Aquatic Research Lab. ogy and management of Lake Trout, Muskellunge, Walleye, and Rudd. He conducts research that helps guide the management, conservation, and restoration of native fishes and their habitat. To support his work, he has acquired over $2.5 million in grants, and looks forward to contributing to the fundraising efforts associated with renovating the ARL. Congratulations! • Coleson Wrege - Gilbert Gleason Memorial Scholarship Dr. Kapuscinski’s research generally focuses on understanding the population characteristics and ecology of fishes inhabiting nearshore areas of the Great Lakes and their connecting waters. He is particularly interested in (1) the ecology and management of Muskellunge, (2) understanding which habitat factors influence fish assemblage structure, (3) determining which environmental factors influence aquatic vegetation assemblages, and (4) understanding how non-native species, especially the omnivorous Rudd, affect ecosystem structure and function. • Samantha Griffin - Headwaters Chapter of Trout Unlimited Fisheries Scholarship To date, Dr. Kapuscinski has published more than 10 technical reports and 14 articles in peer-reviewed, scientific journals, which have focused on the ecol- If you or your organization are interested in establishing a scholarship at LSSU please contact our Foundation Office ([email protected]).

Sturgeon - continued from page 1 natural reproduction is limited with extreme annual variability. The large size of a female sturgeon allows her to produce hundreds of thousands of eggs, yet less than 1% of these eggs will survive due to a poor fertilization rate, poor spawning habitat, and egg predation. Existing Lake Sturgeon populations have stood the test of time and endured the negative impacts of humans and now require our help to survive. Currently, Lake Sturgeon are listed as a threatened species in Michigan, but with the dedicated efforts of biologists, researchers, and conservation enthusiasts these fish have the opportunity to make a comeback in the Great Lakes. Historically 36 Lake Sturgeon populations existed across Michigan waters. Currently 24 populations remain, only 5 of which (including the Kalamazoo River population) are thought to be breeding. Together, Tucker (Michigan Department of Natural Resources), Bauman (US Fish & Wildlife Service), and Lorenz (Gun Lake Tribe) are assisting the Michigan Department of Natural Resources to monitor the population in the Kalamazoo River by tagging and collecting biological information (age, size, and sex) of adults as they migrate upriver to spawn. Naturally produced Lake Sturgeon eggs and larvae are being collected and raised in a unique streamside rearing facility to protect them and ensure a stable environment during their most vital and vulnerable life stages. The young-of-year will be raised and studied throughout the summer of 2014 and grown to 6” before being tagged and released back into the Kalamazoo River in the fall to continue their journey and complete one step along the way of Lake Sturgeon rehabilitation.

LSSU alumni are scattered everywhere; state and federal agencies, tribal and non-profit organizations, to name a few. What is even more amazing is how well represented LSSU is with so few alumni compared to larger universities. It really brings to light the unique learning environment that LSSU offers and highlights the quality education one receives if he/she decides to attend this “small” college. Since graduating in 1997 I have been fortunate to stay in Michigan. Soon after graduation, I received a 180day temporary position with the U.S. Fish and Wildlife Service in Alpena, MI, and I loved the work. Who can complain when your job requires you to launch a boat 80% of the time and catch fish. After I reached the 180 day limit of that position, I competed for, and obtained, a 4-year term position with the F&W Service. This position was again located in Alpena. During this appointment I added several technical skills to my resume. It was still a field based position and I spent a great deal of time on a boat, but I also gained a lot of knowledge and experience on the “management” side of the fishery. As I was entering year 3 of a 4-year appointment, I began looking for my next opportunity. The Bay Mills Indian Community was seeking to fill a vacancy in their Biological Services Program. I decided to throw my name in the hat. After a phone interview and a second in-person interview, the position was offered to me; I finally had full time employment without any term limits! My time at Bay Mills was great. I learned about Tribal natural resources and how important land and water resources are to their community both culturally and spiritually. After three years working for Bay Mills, another opportunity presented itself with the F&W Service in Alpena. This was a permanent full time fishery biologist position. Once again, I was fortunate to compete for and be offered the job. I had finally reached my goal - full time federal employment. Aquatic Research Laboratory | Volume 7 Issue 2 Scott Koproski has enjoyed a 17 year (and counting) career as a fisheries biologist in Michigan. It has been a great journey for me! I recognize the value of each position I have held over the last 17 years. However, without the education that I received from LSSU, I doubt I would have ended up where I am at today! I will be eternally indebted to the faculty and staff at LSSU; long live the Laker legacy! LSSU Students Continue to GRO by Trevor Dunn ‘15 E ach year, hundreds of applicants from across the nation submit proposals to EPA’s prestigious Growing Research Opportunities (GRO) Fellowship. Recipients of the fellowship receive $50,000 to assist with tuition, a paid internship, travel to professional conferences, and funding to conduct a research project. Each year, fewer than 40 of these fellowships are awarded nationwide. In 2014, Trevor Dunn, a Fisheries & Wildlife major continues what is now an LSSU tradition. Our students have successfully competed for these fellowships each of the last 3 years (John Griffioen 2012; Addie Dutton 2013; and Garret Price 2013). Dunn, a junior from Alpena, MI will investigate the impact of road crossings on the ecology of streams. Inputs of sediments and the potential reduction of flow can have a significant influence on many ecological factors. He plans to relate the classification of stream-road crossing condition to sediment input as well as fish diversity and size.

Frog-bit Invasion in the St. Marys River by Alexis Schefka (’15) and Devin Daly (’16) I t was a routine sampling day for LSSU’s Great Lakes coastal wetland monitoring crew in July 2014. While setting up a fyke net to sample wetland fishes in a patch of common reeds in Raber Bay, and close to Raber Bay Resort’s boat launch, the crew noticed extremely high densities of what looked like quarter-sized lily pads. The crew quickly recognized that this was a new type of vegetation, and confirmed that it was an invasive species called European Frogbit (Hydrocharis morsus-ranae). Frog-bit is an aquatic invasive plant that looks similar to a small water lily, but its lily pad is leathery and has a distinct heart-shaped pattern. It also produces a single small white flower during the summer. As observed in Raber Bay, frog-bit grows at densities Page 6 European frog-bit is an invasive aquatic plant capable of altering coastal wetland ecosystems. Continued on page 7 Aquatic Research Laboratory | Volume 7 Issue 2 To view the ARL FishCam visit: www.lssu.edu/arl/fishcam.php Little Rapids – Big Impact by Nate Sleight H istorically, the Little Rapids was an area possessing high flow and supporting diverse fish and macroinvertebrates, similar to the main rapids in the St. Marys River. Over a half century ago, a causeway was built to connect Island No. 1 to Sugar Island, which destroyed the Little Rapids by impounding flow upstream and restricting flow connection to two submerged 6’ culverts. As a result of the lost rapids habitat, the Little Rapids area was identified by the Michigan Department of Environmental Quality as a target for habitat restoration. With the assistance of many local, state, and federal agencies and organizations, the project received federal funding from the National Oceanic and Atmospheric Administration in 2014 and construction will begin in 2015. Flow restoration will be achieved by replacing the two small culverts with larger box culverts spanning 600’. The restoration goal is to improve flow through the causeway and restore habitat for fish, bottom organisms, and wildlife. LSSU’s ARL is leading a baseline assessment of biological organisms inhabiting the Little Rapids area to evaluate the change in composition and abundance of organisms after restoration. The pre-restoration monitoring objectives are to: 1) quantify successful fish reproduction by evaluating larval fish densities and fish community composition, and 2) quantify macroinvertebrate community diversity and abundance prior to the restoration of flow. After two summers of sampling in the Little Rapids, ARL staff and students found that the Little Rapids area currently is dominated by a warmwater fish community typical of a lake system. Natural reproduction of salmonids was observed in the Little Rapids area, but in low numbers. Additionally, few aquatic insects were collected, suggesting poor habitat and water quality. After flow restoration, aquatic insect and coolwater fish diversity and abundance are expected to increase. Post-restoration monitoring will be conducted in 2015 and 2016 to evaluate the project’s success. The Little Rapids restoration has been a valuable learning opportunity for LSSU students, including Aquatic Research Laboratory | Volume 7 Issue 2 two senior thesis students (Zach Berry and Nate Sleight). They have received real-world experiences and an opportunity to contribute to a data set that will help inform restoration projects elsewhere. Nate Sleight (‘15) collects samples to assess the status of the Little Rapids area of the St. Marys River. The work is being conducted to prepare for habitat restoration efforts. Frog-bit - continued from page 6 so thick that it blocks out sunlight for plants below, limits fish movement, and restricts boat traffic. The introduction of frogbit can result in changing ecosystems drastically by reducing plant, invertebrate, and fish diversity in coastal wetlands. Historically, frog-bit was introduced to the lower Great Lakes region from Asia and Europe through the ornamental plant industry. The plant was suspected to have escaped from commercial growers and since spread to a handful of locations in Lake Huron. Unfortunately, the Raber Bay invasion isn’t the first in the St. Marys River; frog-bit was discovered in Munuscong Bay in 2013. It is suspected that frog-bit was introduced to these areas and further spread accidentally by recreational boaters. Frog-bit gets caught on motors and trailers, and if it is not cleaned off then it is transferred to new waters easily. Luckily, European frog-bit was detected early and with the help of LSSU students and the local conservation district, efforts have been made to remove frog-bit near boat launches in Raber Bay. Over 600lbs of frog-bit has been removed since its discovery. This effort, along with outreach to boaters, will help minimize the spread to other critical habitats in the St. Marys River and Great Lakes. Page 7 NON-PROFIT ORG U.S. POSTAGE PAID SAULT STE.
