Resource managers need effective methods to limit the spread of invasive Asian carps (Hypophthalmichthys spp.) into new areas. This study evaluated carbon dioxide (CO2) as a barrier and deterrent to Asian carps in a small outdoor pond. Telemetered silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis) were monitored for 72h (24h before CO2, 24h during CO2, 24h after CO2) using a two-dimensional acoustic telemetry array to evaluate behavioral responses to CO2. Water quality was measured concurrent with acoustic telemetry to determine the concentration and extent of the CO2 plume. Results are intended to provide information on the potential application of CO2 as an invasive fish deterrent...
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...

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...
Recent studies have shown the potential of acoustic deterrents against invasive silver carp (Hypophthalmichthys molitrix). This study examined the phonotaxic response of the bighead carp (H. nobilis) to pure tones (500– 2000 Hz) and playbacks of broadband sound from an underwater recording of a 100 hp outboard motor (0.06–10 kHz) in an outdoor concrete pond (10 × 5 × 1.2 m) at the U.S. Geological Survey Upper Midwest Environmental Science Center in La Crosse, WI. The number of consecutive times the fish reacted to sound from alter- nating locations at each end of the pond was assessed. Bighead carp were relatively indifferent to the pure tones with median consecutive responses ranging from 0 to 2 reactions away...
This dataset contains a combination of physiological and behavioral approaches for characterizing the response of bighead and silver carp to potentially attractive chemicals associated with sex pheromones identified in common carp. The dataset contains eight tables: 1) EOG responses from untreated and masculinized silver carp to prostaglandins, 2) mixture discrimination indices of the prostaglandins tested with the EOG, 3) relative distribution (percentage) of initial behavioral/attractiveness tests of individual PGF’s to silver carp, 4) release rates of prostaglandin mixtures from PGF2α-implanted bigheaded carps, 5) relative distribution (percentage) of masculinized silver carp to PGF2α-implanted carp odors, 6)...
This dataset assesses the responses of native (largemouth bass Micropterus salmoide and bluegill Lepomis macrochirus) and invasive (silver carp Hypophthalmichthys. Molitrix) fishes to an acoustic stimulus (playback of a 100 hp boat motor. Fish were collected from the Illinois River and Emiquon Preserve and implanted with a Passive Integrated Transponder (PIT) tag. Fish movement was monitored using PIT antennas installed in a water control structure (WCS) that connects the Emiquon Preserve to the Illinois River.
The effectiveness of an acoustic barrier to deter the movement of silver carp, Hypophthalmichthys molitrix, and bighead carp, H. noblis, was evaluated. A pond (10 m, x 5 m x 1.2 m) was divided in half by a concrete-block barrier with a channel (1 m across) allowing fish access to each side. Underwater speakers were placed on each side of the barrier opening and an outboard motor noise (broadband sound; 0.06 – 10 kHz) was broadcast to repel carp that approached within 1 m of the channel. Broadband sound was effective at reducing the number of successful crossings in schools of silver carp, bighead carp and a combined school. Repulsion rates were 82.5% (silver carp), 93.7% (bighead carp) and 90.5% (combined). This...
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.

Invasive Asian carps established in the United States spawn in turbulent water of rivers and their eggs and early larvae develop while drifting in the current. The eggs are slightly denser than water and are held in suspension by water turbulence. The eggs are believed to perish if they settle before hatching. It is thus possible to use egg drift modeling to assess the capability of a river to support survival of Asian carp eggs. Data to populate such models include the physical properties of the assessed rivers, and information on egg size, density, and terminal fall velocity (sinking rates). Herein, we present the physical characteristics of the eggs as a function of post fertilization time. We recorded mean egg...

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.

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 accompanies the article "Upstream experience and experimental translocation of invasive bigheaded carps results in increased upstream passage success at a navigation lock in a large river". The data come from the experimental capture and tagging of invasive bigheaded carp with acoustic transmitters and physically moving some groups farther downstream. These transmitters emit signals that are detected and recorded on receivers that are strategically placed above, within, and below Mississippi River Lock and Dam 19 (LD 19). Once the data from the receivers were downloaded, we could show when successful upstream passage through LD19 occurs and compare the origin of the fish and the physical characteristics...
Invasive silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp, collectively referred to as bigheaded carps, threaten aquatic ecosystems of the Upper Midwestern United States. Due to extensive ecological impacts associated with these species, prevention of their further range expansion is the aim for fisheries management. Recent behavioral studies indicate bigheaded carps are deterred by acoustic barriers and exhibit negative phonotaxis in response to anthropogenic sound sources (≥ 150 dB re 1 μPa SPLrms). However, the impact of long-term exposure to these sounds on the hearing capabilities of bigheaded carps has not been well documented. In this study, the auditory evoked potential (AEP) technique...
