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...

In 2013 and 2014, standardized electrofishing was conducted above and below Lock and Dam 19 (i.e., in Pools 19 and 20 respectively) of the Upper Mississippi River (UMR). Sampling was consistent with the UMR Restoration program’s Long Term Resource Monitoring element (LTRM) and The Illinois Natural History Survey’s Long Term Electrofishing program (LTEF) allowing for standardized comparisons among the reaches we sampled and those sampled by the LTRM (Pools 4, 8, 13, and 26) and LTEF (Pools 16-21, and Pool 25). Data in this file is includes A) new data from Pools 19 and 20 and B) data compiled from public sources for other pools (LTRM and LTEF). Generally, data codes are intended to match formatting conventions from...
This dataset includes information from ichthyoplankton sampling for silver carp and bighead carp collected from three main reaches in the Upper Mississippi River Basin, including the La Grange, Peoria, Starved Rock, and Marseilles reaches of the Illinois River, Pool 20 of Mississippi River, and the St. Croix River. Data include the number of bigheaded carp eggs and larvae identified using traditional manual sorting techniques, and genetic data derived from quantitative PCR (qPCR) and 4 bigheaded carp markers (SCTM4/5 and BHTM1/2) that were used to identify the amount of DNA in ichthyoplankton tow samples. These data provide information for natural resource agencies and managers who could use this qPCR screening...

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...

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...
The dataset is comprised of river conditions at La Grange, Peoria, Starved Rock, Marseilles, and Dresden Island Locks and Dams, along the Illinois River. Data were recorded bihourly from 1 Jan 1985 – 31 Dec 2016. For each location, pool elevation (ft), tailwater elevation (ft), head height (ft; calculated by the difference between pool elevation and tailwater elevation), discharge (cfs; when available) and total gate openness (sum of all open gates in ft), are given, where available. Open river conditions were calculated (0 = closed, 1 = open) for each two hour time period. Dam openness was assessed using the U.S. Army Corps of Engineers thresholds for open river conditions at each location.
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.

The dataset and accompanying analysis scripts accompany the article "Bayesian multistate models allow incorporation of spatial dynamics to improve invasive species management". The data are summarized detections from acoustic telemetry receivers (69 KHz) from 353 silver carp (Hypophthalmichthys molitrix) and 170 bighead carp (H. nobilis) surgically implanted with transmitters in the Illinois River, USA. The analysis scripts assess probability of detection, probability of monthly movement between navigation pools on the river, probability of apparent survival, and probability of operable transmitter battery through a Bayesian multistate hidden Markov model.

This dataset includes information derived from a Vemco telemetry array located at Lock and Dam 15 on the Mississippi River near Rock Island, IL and a longitudinal telemetry array that ranges from Pool 14 to Pool 19. Silver carp, bighead carp, and paddlefish 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.

Silver carp (Hypophthalmichthys molitrix) are an invasive species in the Mississippi River Basin; understanding their vulnerability to predation as juveniles may inform control by native predators and predator stocking. Digestion of silver carp recovered from diets makes it difficult to determine the size classes most vulnerable to predation by native fishes. The objective of this study was to determine if total length of silver carp can be predicted from the size of their chewing pad, pharyngeal teeth, and pharyngeal arch, the structures most often found intact in diets. Juvenile silver carp (n=136: <180 mm) were collected using 60 hz pulsed- DC electrofishing and mini fyke nets in 2014 and 2015 from the La Grange...
This dataset includes information from multiple taxa collected from four main reaches in the Upper Mississippi River Basin, including La Grange reach of Illinois River, Pool 2 of Mississippi River, Pool 19 of Mississippi River, and the St. Croix River. Taxa include hydropsychid caddisflies, chironomids, hexagenia mayflies, threeridge mussels, mapleleaf mussels, Wabash pigtoe mussels, bigmouth buffalo, gizzard shad, and bluegill. Seston samples were also collected, in addition to water samples for identifying and enumerating phytoplankton species. Fatty acids, lipids, and stable isotopes were quantified for the aforementioned taxa. Water quality data were recorded at the time of sample collection and discharge data...

Acoustic telemetry data (Vemco, Inc) were collected on invasive silver carp (Hypophthalmichthys molitrix), bighead carp (H. nobilis) and their hybrids in the upper Mississippi River (navigation pools 15-19) to determine movement patterns and preferred habitats during September 2013 through November 2017. We consolidated these data into intervals of fish within-pool residency and intervals of fish transitions into adjacent navigation pools (i.e., dam passages). The combined data set was then parsed into an "upstream passage" data set (in which downstream passage intervals were censored) and and a "downstream passage" data set (in which upstream passage intervals were censored). We then examined the effects of river...
