Three SAS code files were used to analyze data for this study and they included: 1) code to compare the weight of fish distributed to the tanks, 2) code to compare the survival of fish by treatment groups, and 3) code to analyze the weight and condition of fish at exposure termination.
We applied Zequanox using a custom-engineered, boat mounted application system to replicated 0.30 Hectare plots within a small inland lake. The objectives of these applications were to determine if uncontained, open-water Zequanox applications could effectively control zebra mussel populations and protect native unionid mussel populations within zebra mussel infested systems. The datasets included are as follows: Exposure Water Chemistry Hardness and Alkalinity Native Mussel Sonde Water Chemistry Zebra Mussel Density Zebra Mussel Length Zebra Mussel Mortality Zequanox Concentration ShapeFiles: PLOTS, UNIONID, ZEQUANOX CONCENTRATION, ZM_DENSITY, ZM_MORTALITY

Control technology for dreissenid mussels (Dreissena polymorpha and D. bugensis) currently relies heavily on chemical molluscicides that can be both costly and ecologically harmful. There is a need to develop more environmentally neutral control tools to manage dreissenid mussels, particularly in cooler water. Previously, carbon dioxide (CO2) showed selective toxicity for Zebra mussels, relative to unionids, when applied in cool water (12 °C). Carp-Carbon Dioxide (carbon dioxide, CO2) is registered as a pesticide by the U.S. Environmental Protection Agency (EPA) for deterrence of Asian carp and to control aquatic nuisance species when applied under ice (USEPA 2019). The current registration would allow the use of...

Dreissenid management has focused primarily on chemical tools which are efficacious, but not without ecological or economic costs. There is a need for additional control tools that are less expensive, readily available, and will not leave a residue after treatment. Carbon dioxide has these advantages over chemical pesticides and has demonstrated effectiveness for control of a range of aquatic invasive species, including dreissenid mussels. Carbon dioxide was lethal to adult zebra mussels at levels that were safe to juvenile unionid mussels and lower levels cause detachment and gaping. Dreissenid veligers are more sensitive than adults to water quality conditions, including pH. Therefore, we hypothesized that effective...

This dataset contains the supplementary data to the dataset entitled "Assessments of the binary mixtures of four toxicants on Zebra Mussel (Dreissena polymorpha) mortality." These data describe the exposure conditions to include water chemistry before, during, and after exposures as well as mussel condition throughout the study. Monitored water chemistry parameters include dissolved oxygen, temperature, and pH. Periodic measurements of alkalinity, total hardness, and specific conductance where taken before each exposure period. Mussel condition was also assessed at the initiation of each exposure. Mussel condition included shell length and tissue dry weight.
Five R Markdown files (.Rmd) were created for the study entitled: Assessments of the binary mixtures of four toxicants on Zebra Mussel (Dreissena polymorpha) mortality. R codes were used to determine toxicant mixture ratios, summarize data, and analyze dose-response relationships in single toxicant and toxicant mixture trials. Files are described in the readme file in the order in which they were used for the study. Each R Markdown file has a complimentary R Script file (.R) with the same file name. All R Markdown files were created in RStudio version 1.2.1335 with R version 3.6.1 and Tidyverse version 1.3.0. Additional packages are listed in braces, “{},” with the corresponding R Markdown description.

This dataset captures the Zebra Mussel dose-response to four independent toxicants and each binary mixture of those toxicants. Toxicants included EarthTec QZ, Clam-Trol CT-2 (syn. Spectrus CT1300), niclosamide, and potassium chloride. Each dose of toxicant was verified with either ICP-OES or UHPLC, depending on analyte, and comparison to a standard curve. Mortality was tabulated for each observation.

Zequanox® is an EPA-registered biopesticide for controlling populations of dreissenid mussels (zebra and quagga mussels). Zequanox has demonstrated selective toxicity toward dreissenid mussels; however, a recent laboratory study indicated the potential for Zequanox to impact a non-target salmonid species. We assessed the potential exposure risk by observing the avoidance behavior of two representative species of cold-, cool-, and warm-water fish (lake trout, brook trout, lake sturgeon, yellow perch, fathead minnow, and bluegill). Fish were subjected to the maximum allowable concentration of Zequanox per the product label (100 mg/L active ingredient). Naïve juvenile fish (n = 30 per species) were individually observed...
The efficacy and subsurface application of Zequanox®, a commercially prepared spray-dried powder formulation of Pseudomonas fluorescens (strain CL145A), were evaluated for controlling zebra mussels (Dreissena polymorpha) within 27-m2 enclosures in Lake Minnetonka (Deephaven, Minnesota). Five treatments consisting of (1) two whole water column Zequanox applications, (2) two subsurface Zequanox applications, and (3) an untreated control were completed on each of three independent treatment days during September 2014. The two types of samplers used in the study were (1) custom built multi-plate samplers (type 1 samplers), with wood, perforated aluminum, and tile substrates that were placed into Robinson’s Bay in June...

Zebra mussels (Dreissena polymorpha) have continued their spread within inland lakes and rivers in North America despite diligent containment and decontamination efforts by natural resource agencies and other stakeholders. Identification of newly infested waterways with early detection surveillance programs allows for rapid response zebra mussel eradication treatments in some situations. Previous eradication treatments have been conducted during times of variable water temperatures and temperature has been shown to influence the efficacy of molluscicides. Natural resource managers would benefit from knowledge regarding the impacts of water temperature and exposure duration on toxicity of molluscicides to zebra mussels....

Alternatives to chemicals for controlling dreissenid mussels are desirable for environmental compatibility, but few alternatives exist. Previous studies have evaluated the use of electrified fields for stunning and/or killing planktonic life stages of dreissenid mussels, however, the available literature on the use of electrified fields to control adult dreissenid mussels is limited. We evaluated the effects of sinusoidal alternating current (AC) and square- wave pulse direct current (PDC) exposure on the survival of zebra mussels at water temperatures of 10, 15, and 22°C. Peak voltage gradients of ~ 17 and 30 Vp/cm in the AC and PDC exposures, respectively, were continuously applied for 24, 48, or 72 h. Peak power...
Control technology for dreissenid mussels (Dreissena polymorpha and D. bugensis) currently relies heavily on chemical molluscicides that can be both costly and ecologically harmful. There is a need to develop more environmentally neutral control tools to manage dreissenid mussels, particularly in cooler water. Carbon dioxide has been shown to be lethal to several species of invasive bivalves, including zebra mussels and Asian clams (Corbicula fluminea). We evaluated the effects of various treatment regimes [i.e., exposure duration and pCO2 (partial pressure of carbon dioxide)] on mortality, byssal thread formation and attachment, and narcotization behavior. The effects of elevated carbon dioxide on nontarget native...
