Data and R code to support: Estimating densities of zebra mussels (Dreissena polymorpha) in early invasions using distance sampling
(2019-01-18) Ferguson, Jake M; Fieberg, John R; McCartney, Michael A.; Blinick, Naomi S.; Schroeder, Leslie; jakeferg@umn.edu; Ferguson, Jake M; Minnesota Aquatic Invasive Species Research Center (MAISRC)
These files are the data and code needed to reproduce the analysis of the manuscript "Estimating densities of zebra mussels (Dreissena polymorpha) in early invasions using distance sampling". The data include spatial coordinates of transects used to survey for zebra mussels in Lake Sylvia and Lake Burgan in the summer of 2017, the counts of zebra mussels on each transect, and environmental covariates collected along transects and at each detection. We also provide the R code needed to process and analyze these data following the distance survey approach described in the manuscript. We provide code for a straightforward distance survey, which doesn't include any spatial covariate information, as well as a more computationally intensive analysis that does include spatial covariates.

(2019-11-27) Gilmanov, Anvar; agilmano@umn.eu; Gimanov, Anvar; Minnesota Aquatic Invasive Species Research Center (MAISRC)
The Computational Fluid Dynamic (CFD) and Agent-Based (AB) Code initially developed by Dan Zielinski (Zielinski, et al., 2018) and further improved by Anvar Gilmanov (Gilmanov, et al., 2019) are presented in this documentation. The solution of 3D fluid equations obtained by ANSYS-FLUENT is not considered here. We will focus on AB-Code with a description of how to simulate fish swimming in the given fluid environmental. Description of the algorithm, computational input parameters, source code in Fortran and examples on fish swimming simulations through Lock and Dam #2 at the Mississippi River are presented.
Data and R code for analysis of walleye and yellow perch age-0 length in Minnesota's Large Lakes
(2019-12-10) Hansen, Gretchen J A; Bethke, Bethany J; Ahrenstorff, Tyler D; Dumke, Josh; Hirsch, Jodie; Kovalenko, Katya E; LeDuc, Jaime F; Maki, Ryan P; Rantala, Heidi M; ghansen@umn.edu; Hansen, Gretchen; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Invasive species represent a threat to aquatic ecosystems globally; however, impacts can be heterogenous across systems. Documented impacts of invasive zebra mussels (Dreissena polymorpha) and spiny water fleas (Bythotrephes cedarstroemi; hereafter Bythotrephes) on native fishes are variable and context dependent across locations and time periods. Here, we use a hierarchical Bayesian analysis of a 35-year dataset on two fish species from 9 lakes to demonstrate that early life growth of ecologically important fishes are influenced by these aquatic invasive species. Walleye (Sander vitreus) grew more slowly throughout their first year of life, and were on average 12 or 14% smaller at the end of their first summer following invasion by Bythotrephes or zebra mussels, respectively. Yellow perch (Perca flavescens) growth was less affected by invasion. Yellow perch on average grew more slowly in their first year of life following invasion by zebra mussels, although this effect was not statistically distinguishable from zero. Early life growth of both walleye and yellow perch was less tightly coupled to degree days in invaded systems, as demonstrated by increased variance surrounding the degree day-length relationship. Smaller first-year size is related to walleye survival and recruitment to later life stages and has important implications for lake food webs and fisheries management. Future research quantifying effects of zebra mussels and Bythotrephes on other population-level processes and across a wider gradient of lake types is needed to understand the mechanisms driving observed changes in walleye growth.
Complete Data and Analysis for: Constraining invader dominance: Effects of repeated herbicidal management and environmental factors on curlyleaf pondweed dynamics in 50 Minnesota lakes
(2020-01-08) Verhoeven, Michael R; Larkin, Daniel J; Newman, Raymond M; michael.verhoeven.mrv@gmail.com; Verhoeven, Michael R; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Curlyleaf pondweed (Potamogeton crispus) is one of the most widespread and widely managed aquatic invasive plants in North America. Despite decades of management, the efficacy of long-term management strategies and the effects of environmental drivers on curlyleaf pondweed populations remain uncertain. To evaluate the effects of management and environmental factors on within-lake distribution and local density of curlyleaf pondweed, we collated monitoring data from aquatic plant point-intercept surveys collected by a variety of lake managers across Minnesota, USA. The goal of the study was to examine the influence of herbicide treatment, water clarity, snow depth, and ice cover duration on curlyleaf pondweed distribution and density between 2006 and 2015. The data included in this repository includes the complete dataset as a comma-separated-value file and all Program R code necessary to replicate the data processing, analysis, and visualizations used in the study.
Data from: Tests in a semi-natural environment suggest that bait and switch strategy could be used to control invasive Common Carp
(2020-07-10) Hundt, Peter J; Amberg, Jon; Sauey, Blake; Vacura, Kristen; Bajer, Przemyslaw G; hundt002@umn.edu; Hundt, Peter J; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Common Carp (Cyprinus carpio Linnaeus, 1758), is a highly invasive species that has had profound effects on biodiversity and ecosystem services. Many Carp management methods have been applied including physical removal, pesticide treatments of whole lakes, and water drawdowns. Herein, we tested key elements of a potential “bait and switch” approach in which corn could be used to induce feeding aggregations of Carp and then switched for corn pellets with a pesticide Antimycin-A (ANT-A) to selectively target the Carp. First, laboratory experiments were used to determine if addition of lethal concentrations of ANT-A to corn pellets deterred Carp from eating corn-based food pellets. Second, a pond experiment tested if a corn-based bait containing ANT-A functioned as a species-specific Carp management tool in a semi-natural environment with three common native fishes: White Sucker (Catostomus commersonii Lacepède, 1803), Yellow Perch (Perca flavescens, Mitchill, 1814), and Bluegill (Lepomis macrochirus Rafinesque, 1819). The use of baited sites by Carp and native species was monitored using passive integrated transponder (PIT) tags. Mortality of each species and presence of corn in their digestive tracts was also monitored.
KHV disease data from wild Cyprinus carpio from Lake Elysian (Le Seuer, MN) and cohabitation disease trial of Cyprinus carpio, Pimephales promelas and Carassius auratus
(2020-09-28) Tolo, Isaiah; Phelps, Nicholas B. D.; phelp083@umn.edu; Phelps, Nicholas; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Koi herpesvirus (KHV) is an important pathogen worldwide and a common cause of mass mortality events of wild common carp (Cyprinus carpio) in North America, however reference strains and genomes obtained from wild carp are not available. Additionally, it is unclear if fishes native to North America are susceptible to KHV infection due to incomplete susceptibility testing. Here we present the first North American type strain and whole genome sequence of KHV isolated from wild carp collected from a lake with history and recent incidence of carp mortality. Additionally, the strain was used in an in-vivo infection model to test the susceptibility of a common native minnow (Pimephales promelas) and goldfish (Carrasius auratus) which is invasive in North America. Detection of KHV DNA was confirmed in the tissues of a single fathead minnow but the same tissues were negative for KHV mRNA and samples from exposed fathead minnows were negative on cell culture. There was no detection of KHV DNA or mRNA in goldfish throughout the experiment. KHV DNA in carp tissues was reproducibly accompanied by detection of KHV mRNA and isolation on cell culture. Additionally, environmental KHV DNA was detected on all tank filters during the study. These findings suggest that fathead minnows and goldfish are not susceptible to KHV infection and that detection of KHV DNA alone in host susceptibility trials should be interpreted with caution
Network connectivity patterns of Minnesota waterbodies and implications for aquatic invasive species prevention

D.; phelp083@umn.edu; Phelps, Nicholas B D; Minnesota Aquatic Invasive Species Research Center (MAISRC); Division of Health Policy and Management, School of Public Health, University of Minnesota; Odum School of Ecology, University of Georgia; Department of Fish and Wildlife Conservation, Virginia Polytechnic Institute and State University; Key Laboratory of Animal Ecology and Conservation Biology, Chinese Academy of Sciences; Department of Veterinary Population Medicine, College of Veterinary Medicine, University of Minnesota
The data contains simulated boater movements across lakes in the state of Minnesota (MN). The data were simulated based on the boater inspection program conducted by the Minnesota Department of Natural Resources in 2014-2017. Using the inspection survey, we employed machine learning technique, XGBoost, to construct three predictive boater movement models. First, we predicted the number of boater traffic on a lake for a year. Second, we predicted the boater connection between any pair of lakes in MN. Third, we predicted the number of boaters between two lakes that were predicted to have connection.
Complete Data and Analysis for: Niche models differentiate potential impacts of two aquatic invasive plant species on native macrophytes
(2021-01-22) Verhoeven, Michael R.; Glisson, Wesley J.; Larkin, Daniel J.; michael.verhoeven.mrv@gmail.com; Verhoeven, Michael R; Minnesota Aquatic Invasive Species Research Center (MAISRC)
The goal of our study was to elucidate the mechanisms by which two invasive aquatic plant species (Myriophyllum spicatum and Potamogeton crispus) interact with native plant communities in lakes in Minnesota, USA. We used an observational dataset of aquatic plant occurrences—and associated light availability, depth, and temperature—to construct probabilistic models of the ecological niches of 34 aquatic plant species. We then compared shared-ness of these niches between the two invasive aquatic plants and 32 native species to infer the degree of direct competitive interaction. This repository contains the complete dataset as a comma-separated-value file and Program R code necessary to replicate the data prep, exploration, analysis, and visualizations presented in the manuscript.

(2021-02-12) Levers, Lucia; Pradhananga, Amit; llevers@umn.edu; Levers, Lucia; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Willingness to pay data from surveys conducted with recreationists (primarily boaters) at four Minnesota Lakes (Minnewaska, Koronis, Gull, and Pokegama) in the summer of 2019.
Carp Edema Virus Host Range Study in Lake Swartout and Outbreaks in four other lakes
(2021-03-02) Tolo, Isaiah; Phelps, Nicholas B. D.; tolo0007@umn.edu; Phelps, Nicholas; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Mass mortality events of common carp (Cyprinus carpio, carp) associated with carp edema virus (CEV) alone or in coinfections with koi herpesvirus (KHV), is an emerging issue. Despite recent outbreaks of CEV in wild carp populations, the host range of North American species has not been well studied. To that end, we intensively sampled carp (n = 106) and co-habiting native fish species (n = 5 species; n = 156 total fish) from a CEV-suspect mass-mortality event of carp in a small Minnesota lake (Lake Swartout). Additionally, fecal and regurgitant samples (n = 73 each) from double-crested cormorants (Phalacrocorax auritus, DCCO) were sampled to test the potential of DCCO to act as a vector for virus transmission. CEV was confirmed to be widespread in the Lake Swartout carp population during the outbreak with high viral loads and histological confirmation, suggesting that CEV was the cause of the mortality event. There were no detections of CEV in any native fish species; however, DCCO regurgitant and fecal samples were positive for CEV DNA. In addition, three CEV-positive and one CEV+KHV-positive mortality events were confirmed with no observed mortality or morbidity of non-carp species in other lakes. This study provides evidence that CEV infection and disease may be specific to carp during mortality events with mixed-species populations, identifies DCCO as a potential vector for CEV, and further expands the known range of CEV, as well as coinfections with KHV, in North America.

Complete Data for: Desiccation tolerance of the invasive alga starry stonewort (Nitellopsis obtusa) as an indicator of overland spread risk
(2021-10-13) Glisson, Wesley J.; Wagner, Carli K.; Verhoeven, Michael R.; Muthukrishnan, Ranjan; Contreras-Rangel, Rafael; Larkin, Daniel J.; wjglisson@gmail.com; Glisson, Wesley, J; Minnesota Aquatic Invasive Species Research Center (MAISRC)
The ability of invasive macrophytes to survive out of water, i.e., their desiccation tolerance, is an important indicator of capacity for spread to new waterbodies through overland transport. Invasion by the alga starry stonewort (Nitellopsis obtusa [Desv. in Loisel.] J. Groves; Characeae) in North America is likely driven via overland transport, but little is known regarding its ability to remain viable out of water. We conducted laboratory and outdoor experiments to evaluate desiccation tolerance of N. obtusa propagules, including single stem fragments, small and large clumps of fragments, and bulbils (asexual reproductive structures). Propagules were removed from water after 15 min to 5 d to identify desiccation thresholds. The data from these experiments are documented and available here for public availability and use.
Complete data for Overwinter survival of Corbicula fluminea in a central Minnesota lake
(2021-11-01) Weber, Megan M; Cibulka, Daniel; mmweber@umn.edu; Weber, Megan M; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Corbicula fluminea is regarded as one of the most pervasive freshwater aquatic invasive species in the world. It has been widely cited to have a lower lethal temperature threshold of 2 degrees Celcius, which suggests the species would be unable to survive in Minnesota outside of areas of thermal refuge from sources such as power plant, water treatment facility, and other raw water user effluent). In August 2020 a volunteer participating in Starry Trek, an aquatic invasive species early detection event, recovered live C. fluminea from an inland Minnesota lake with no known thermal refuge (Briggs Lake, Sherburne County). This data set documents the distribution, overwinter survival, and size class structure of the population in Briggs Lake and observational data at a nearby lake (Big Lake, Sherburne County) where additional clams were discovered by a volunteer towards the end of the Briggs Lake project timeline. The data from this study are available here for public use.
Phenology data for watermilfoil taxa Myriophyllum spicatum, M. sibiricum, and M. spicatum x M. sibiricum in Minnesota, USA, 2017 - 2018
(2021-11-15) Glisson, Wesley J; Larkin, Daniel J; wjglisson@gmail.com; Glisson, Wesley; Minnesota Aquatic Invasive Species Research Center (MAISRC)
In North America, the hybrid aquatic plant Myriophyllum spicatum × Myriophyllum sibiricum (hybrid watermilfoil, HWM) is a cross between non-native invasive Eurasian watermilfoil (M. spicatum, EWM) and native northern watermilfoil (M. sibiricum, NWM). We compared HWM to its parental taxa, EWM and NWM, by examining the amount and timing of: 1) flowering, 2) surface cover, and 3) biomass (using stem counts as a proxy). We conducted repeat surveys of Myriophyllum beds at eight lakes (2–3 lakes/taxon) in the Minneapolis-St. Paul Metropolitan area (Minnesota, USA) between June 2017 and November 2018. To sample biomass without destroying plants, we developed a novel sampling device that uses underwater video to measure Myriophyllum stems; we validated the utility of this device by comparing Myriophyllum stem counts and biomass collected from the same locations. The data from these studies are provided and documented here.
Phenology data for the invasive macroalga Nitellopsis obtusa (starry stonewort) in Minnesota, USA, 2017 - 2018
(2021-11-22) Glisson, Wesley J; Muthukrishnan, Ranjan; Wagner, Carli K; Larkin, Daniel J; wjglisson@gmail.com; Glisson, Wesley; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Understanding the phenology of aquatic invasive plants is critical for evaluating and predicting their ecological impacts and timing control efforts. Despite its 45-year invasion history in North America, relatively little is known about the phenology of the invasive macroalga Nitellopsis obtusa (starry stonewort). We tracked N. obtusa phenology from 2017-2018 in two Minnesota (USA) lakes representing northern and southern clusters of N. obtusa invasion in Minnesota. We measured N. obtusa biomass and counted bulbils (asexual reproductive structures) throughout the growing season and in winter, under ice. These data are provided and documented here.
Investigation of cyprinid herpes virus 3 (CyHV-3) disease periods and factors influencing CyHV-3 transmission in a low stocking density infection trial
(2021-12-13) Tolo, Isaiah; tolo0007@umn.edu; Tolo, Isaiah; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Pathogens are the primary limitation to aquaculture production of fish and a major issue in consideration of the interface between cultured and wild populations of fishes worldwide. While rapid spread of fish pathogens between populations (wild or farmed) is generally anthropogenic and the result of trade, the mechanisms of transmission once a pathogen has been introduced to a fish population are not well understood. The most widespread pathogen impacting both aquaculture and wild populations of common carp (Cyprinus carpio, carp) is Cyprinid herpesvirus 3 (CyHV-3). To understand how CyHV-3 is transmitted in a population we conducted a series of infection trials, designed to determine the kinetics CyHV-3 infections, identify the contributions of direct and indirect forms of CyHV-3 transmission, and to determine the contributions of contact rate, viral load, pathogenicity, and contact type. We found that direct contact between fish was the primary mechanism of CyHV-3 transmission rather than transmission through contaminated water. Additionally, CyHV-3 transmission occurred primarily during the incubation period of CyHV-3, prior to the appearance of disease signs and disease-associated reduction in contact rate.
Data for A small native predator reduces reproductive success of a large invasive fish as revealed by whole-lake experiments
(2022-01-10) Poole, Joshua R; Bajer, Przemyslaw G; bajer003@umn.edu; Bajer, Przemyslaw; Minnesota Aquatic Invasive Species Research Center (MAISRC)
The extent to which native fish communities might control the success of invasive fish has been of interest to ecologists, but it has been rarely addressed using experiments. We conducted an experiment in six small lakes in the Upper Mississippi Region to test the effects of a small native predator, bluegill sunfish (Lepomis macrochirus) on the recruitment of a large, invasive fish, the common carp (Cyprinus carpio). Bluegills are predominant throughout the region and were previously shown to consume carp eggs and larvae. We stocked both lakes at each of our 3 sites with adult carp (spawners) and one lake at each site with bluegills. We repeated the experiment at two of the three sites for two consecutive years. In each lake we assessed the abundance of post-larval carp one month after spawning (backpack electrofishing surveys) and at the end of the season (mark-recapture). For each site/year combination, catch rate of post-larval carp was typically an order of magnitude higher in control than bluegill lakes, but it often declined quickly over time. The abundance of end-of-seasonal juveniles was significantly higher (no 95% CI overlap) in control lakes than in bluegill lakes, except for one pair of lakes during one year when both the control and bluegill lake had similar, low abundance of end-of-season carp. Overall, our results support the hypothesis that common carp recruitment is substantially reduced in habitats dominated by bluegills. We also suggest our results may be applicable to other species, and that managers should explore how predation on early life stages may control other invasive species.
Data for Evaluation of a broadband sound projected from the gates of a navigation lock in the Mississippi River shows it to be a weak deterrent for common carp and unable to block passage
(2022-01-19) Riesgraf, Andrew T.; Finger, Jean S.; Zielinski, Daniel P.; Dennis III, Clark E.; Whitty, Jeff M.; Sorensen, Peter W.; soren003@umn.edu; Sorensen, Peter W.; Minnesota Aquatic Invasive Species Research Center (MAISRC)
There is an urgent need to block the passage of carp and other invasive fishes through navigational locks in large rivers. Although the broadband sound of an outboard motor has been shown to strongly repel three species of carp in laboratory flumes and to a lesser extent inside of a lock chamber, it has not yet been tested to see if it can stop carp from entering a lock. To test this possibility, we attached speakers to lock gates and played the sound of an outboard motor while measuring its efficacy by tracking free-ranging transplanted tagged common carp in its vicinity. Eight groups of 20 carp were tested while the sound system was turned on and off for 2 week periods. When the sound system was on, these carp spent approximately one-third less time in front of the gates than when it was off which when modeled by GLMM was shown to no greater than the effects of river discharge or temperature. Further, there was no indication that this sound blocked carp from entering and presumably passing through the lock. However, the number of times that tagged carp entered the lock was low even when the sound was off. A number of factors may have contributed to the limited efficacy of this deterrent system including the sound itself.
Data for: "Effect of light on macrophyte sprouting and assessment of viable seedbank to predict community composition"
(2022-02-22) Dunne, Melaney A; Newman, Raymond M; Newma004@umn.edu; Newman, Raymond M.; Minnesota Aquatic Invasive Species Research Center (MAISRC)
These are data from the paper: “Effect of light on macrophyte sprouting and assessment of viable seedbank to predict community composition” Sediments cores from each lake were pooled and homogenized and placed in trays with controlled lighting and temperature. Germination was determined for low light conditions (low water clarity), higher light conditions (high water clarity) and a treatment with gibberellic acid to induce germination and sprouting (maximum emergence – called maximum germination in the JAPM publication). Trays were examined weekly for newly sprouted plants that were identified to species and enumerated.
