Observations and subtle shifts of vegetation communities in western Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities. Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic vegetation communities and establish baseline conditions for assessing future effects. Existing aerial imagery was used with object-based image analysis to detect and map aquatic vegetation in the western basin of Lake Erie.

Data set includes water Sr:Ca, Ba:Ca, and δ18O for the Upper Mississippi River and tributaries and otolith Sr:Ca, Ba:Ca, and δ18O data from bigheaded carp collected in pools 19-21 of the Upper Mississippi River. Abstract from manuscript: Knowledge of environments used during early life history and movement patterns of Bighead Carp (Hypophthalmichthys nobilis) and Silver Carp (H. molitrix), collectively termed bigheaded carps, in the Upper Mississippi River (UMR) would be valuable for informing control measures to limit further population expansion and impacts of these species. Lock and Dam 19 (LD19) is a high-head dam on the UMR that delineates downriver areas where bigheaded carps are well-established from upriver...

This dataset contains Sr:Ca of water and fin ray samples of native fish to evaluate upstream fish passage through a navigation lock in the Des Plaines River (Brandon Roads Lock and Dam). Fin ray samples from several native fish taxa (catostomids, ictalurids, centrarchids, and lepisosteids) were collected in two river reaches downstream of Brandon Roads Lock and Dam, and in a river reach upstream of Brandon Roads Lock and Dam. Fin ray Sr:Ca derived from microchemistry analyses of fin ray materials from a laser ablation transect is included as both edge values and entire transect (including edge). Edge values of Sr:Ca were used to characterize chemical signatures of residency for each of the rivers and make comparisons...

Description of Work This work began by assembling fish toxicant data into a common database and examining the database for trends in toxicant data. The trends found in the toxicant database were linked to physiochemical properties of the individual toxicants. Combining the toxicant trends with the physiochemical properties may allow for the prediction of toxicity and the identification of chemicals with selectivity for the Asian carp. Identifying a selective toxicant may provide control of Asian carps while minimizing effects on other non-target aquatic species. When Asian carp specific toxicants are identified from the initial screen within the database these toxicants are then further screened in toxicity assays...

To evaluate how bigheaded carps use a restored backwater habitat, their passages into and out of and residency within a backwater was monitored using acoustic telemetry. This dataset describes the results of this study and was used to compare activity of bigheaded carps between species, at a diel scale, among seasons, and how activity related of environmental conditions. Calculation of passages and residency are available in the thesis of Douglas Schultz (Southern Illinois University, 2006). http://fishdata.siu.edu/schultz.pdf

Data set includes water Sr:Ca, Ba:Ca, and δ18O for the Mississippi River and tributaries, and otolith Sr:Ca, Ba:Ca, and δ18O data from bigheaded carp (Silver Carp and BIghead Carp) collected in navigation pools 16-19 of the Upper Mississippi River in 2016 to 2018. Bigheaded carp (Bighead Carp and Silver Carp) are invasive species in the US and have spread throughout most of the lower Mississippi River Basin. Population abundance upstream of Lock and Dam 19 (LD19) on the Upper Mississippi River (UMR) has likely been limited by the high-head dam at this location, which restricts all upstream fish passage to the lock chamber. To determine early-life environments of adult bigheaded carp captured upstream LD19 at the...

Description of Work To achieve a better understanding of seasonal habitats and migratory behaviors of Asian carp, we will conduct studies using telemetry, sonar and conventional fish sampling to determine 1) if, when, and where Asian carp congregate, 2) habitat overlap between Asian carp and native fishes, especially native filter-feeding fishes and potential predators, and 3) the suitability of large rivers and tributaries for spawning by Asian carp. We will also assess feeding behaviors by sampling food particles from areas with telemetry-tagged fish, at random sites and in Asian carp stomachs. Food from these sources will be characterized with a particle analyzer, genetics and microscopy to determine preferences...
Studied changes in the profiles of digestive enzymes of two planktivorous fishes, silver carp and gizzard shad. Results from this study will help scientists develop and design a novel oral delivery formulation to control the invasive silver carp while minimizing impacts on native fishes like the gizzard shad.
These datasets include data that was used to evaluate the efficacy of carbon dioxide (CO2) injected under-ice as a tool for reducing the overwinter survival of invasive carps.

In 2016, for the first time, an abundance of age-0 silver carp (Hypophthalmichthys molitrix) were captured at several sites upstream of Lock and Dam 19 on the Upper Mississippi River near Keokuk, Iowa. These data were collected in an attempt to determine the early life environments and frequency and timing of the reproductive events that led to a large year class of age-0 silver carp. This information is important for informing decisions about control measures. We sampled these fish to determine age (days) and early life environments using their otoliths. Sampled age-0 silver carp were collected from navigation Pools 18 and 19 from July–October 2016 using a variety of sampling gears. We aged these fish by counting...
This data contains environmental DNA (eDNA) sample assay results that were collected from water samples taken from a tank housing Asian carp and placed either on ice or at room temperature. At both treatment temperatures, water samples were left untreated or were treated with an ethanol and sodium acetate solution (EtOH-NaAc). This was done to evaluate an ethanol and sodium acetate solution to maintain the integrity of the DNA samples for the time between collection and lab testing. Every day for 6 days following collection, a subset of the samples was removed from each treatment and DNA was extracted and nuclear and mitochondrial markers were assayed with qPCR. Results showed comparable persistence of DNA between...

Description of Work Hydroacoustic surveys were used to characterize the distribution of fish within the backwater before, during and after the addition of algal feeding attractants, establishment of a water gun barrier and commercial fishing activities. Algal feeding attractants were injected at predetermined locations in the backwater to attract and concentrate Asian carp in the closed portion of the backwater. Nine days after the first algal feeding attractant was added, a water gun barrier was established at the narrowest location on the backwater. The water gun barrier was established about 14 hours before commercial fishers began 3 consecutive days of carp removal; the water gun barrier operated continuously...
Bighead Carp, Silver Carp and Grass Carp (collectively Asian carp) were introduced to North America in the 1960s and 70s and have established in the lower Mississippi River basin. Previously published evidence for spawning of these species has been limited in the upper Mississippi River to just below Dam 22 (near Saverton, MO). In 2013 and 2014, we sampled ichthyoplankton at 18 locations in the main stem of the upper Mississippi River from Dam 9 through Dam 19 and in four tributary rivers that empty into the Mississippi River (Des Moines, Skunk, Iowa and Wisconsin Rivers). We identified eggs and larvae using morphological techniques and then used genetic tools to confirm species identity. The spawning events we...
This dataset includes information derived from a Vemco telemetry array located at Lock and Dam 19 on the Mississippi River near Keokuk, IA. Ten fish species, comprised of both native and invasive species, were detected with this system. Lock Queue Reports, which detail the daily lock operation for river traffic, were obtained from the U.S. Army Corps of Engineers. Temperature data were recorded on the Vemco receivers and stage height data were obtained from the U.S. Army Corps of Engineers. Six worksheets are included in this file, including a meta-data sheet that describes the datasets, provides variable names, and associated units of measure.
Spreadsheets include data that was used to evaluate the efficacy of carbon dioxide (CO2) deterrence at different temperatures in invasive carps. There are 8 csv files and 2 folders containing text documents associated with this study.

Observations and subtle shifts of vegetation communities in Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities. Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic vegetation communities and establish baseline conditions for assessing future effects. Existing aerial imagery was used with object-based image analysis to detect and map aquatic vegetation in the eastern basin of Lake Erie.
This dataset was used to evaluate bigheaded carp movement (net and total) between the upper and lower Illinois River and to create a multistate model in Program MARK to estimate movement probabilities among river pools.
Silver and bighead carp frequency detection was evaluated in response to 100 Hz to 9 kHz using auditory evoked potentials (AEPs). AEPs, consisting of measured minimum Sound Pressure Levels (SPL; dB re 1 ms-2) and Particle Acceleration Thresholds (PAT; dB re 1 ms-2). SPL and PAT were recorded every 100 Hz from 100 Hz to 1000 Hz plus 1500, 2000, 3000, 4000, and 5000 Hz for five individual Silver Carp and five individual Bighead Carp. Minimum detectable PAT and SPLs were measured at 100, 200, 400, 600, 800, 1000, 2000, 4000, and 5000 Hz for three individual Common Carp.
Locks and dams are possible management points to block the spread of invasive Asian carps in the United States. Infusion of carbon dioxide (CO2) into water is one deterrent strategy being considered at navigational structures to reduce upstream fish passage that would not directly interfere with lock and dam operations. The goal of this study was to determine lethal concentrations of CO2 to non-target species. Bluegill (Lepomis macrochirus) and Fathead minnows (Pimephales promelas) were exposed to CO2 continuously for 12 hours using a diluter system. Trials were performed on both species at target water temperatures of 5, 15, and 25°C. See related manuscript for additional details on experimental methods.

These environmental DNA data and corresponding water quality data were collected and analyzed by the Fish and Wildlife Service in 2017. The samples were collected from 4 sites in pools 17 and 18 in the Upper Mississippi River on 3 sampling trips. The data was used to study occupancy modeling of eDNA data and determine optimal sampling effort required for reliable detection of invasive Bighead Carp and Silver Carp in streams with similar attributes at the Mississippi River.
