Data collected from a comprehensive set of hydrodynamic experiments conducted with live grass carp eggs and larvae, to evaluate drifting and swimming patterns with 3 different in-stream obstructions: (1) a gravel bump, (2) a single cylinder, and (3) submerged vegetation. The hydrodynamic behavior of eggs and larvae with each obstruction was continuously monitored for about 85 consecutive hours. Transient spatial distributions of the locations of eggs and larvae across the water column were generated for each flow scenario.

Diploid and triploid Grass Carp (Ctenopharyngodon Idella) tagged with acoustic transmitters were observed in Truman Reservoir, Missouri from February 2017 to March 2019 to determine habitat usage in winter. Habitat parameters were measured at used and available sites to model habitat preference. In addition, tagged fish were targeted during removal attempts to determine the efficacy of using tagged Judas Grass Carp in removing wild conspecifics. This dataset includes information on tagged Grass Carp and habitats they selected as well as capture events and characteristics of the wild fish caught during these attempts.

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.

Diploid and triploid Grass Carp (Ctenopharyngodon Idella) tagged with acoustic transmitters were observed in Truman Reservoir, Missouri from January 2017 to October 2019 to determine longitudinal movements potentially associated with spawning. Passive acoustic receivers were deployed throughout the reservoir and its tributaries to monitor fish movements as they traversed up and downstream. This dataset consists of the detections made by passive receivers and those made by manual tracking.

A series of laboratory experiments were conducted to better understand the behavior of grass carp eggs and larvae in moving water in order to develop and implement new strategies for control and prediction of their dispersal and drift at early life stages. Settling velocity and density of a representative sample of eggs were estimated, and three trials of flume experiments with different flow conditions were conducted with live eggs in a temperature-controlled setting with a mobile sediment bed. In these trials, egg and larval stages were continuously analyzed over periods of 80 hours; and eggs and larvae interactions with the flow and sediment bed were monitored and characterized qualitatively and quantitatively....

Black carp Mylopharyngodon piceus and grass carp Ctenopharyngodon idella are morphologically similar species imported from eastern Asia to North America as biological control organisms. Preferred identification methods are coloration and pharyngeal tooth form. Grass carp possess serrated teeth and black carp molariform teeth. Examination of pharyngeal teeth causes extensive damage to a specimen, and is labor and time intensive. Coloration can vary within a species and fades with preservation. We present a suite of external characteristics consisting of a truss network canonical variate analysis of distance measurements among landmarks on the lateral view of the head of each fish, the ratio of head length to mouth...

Grass Carp (Ctenopharyngodon idella) are a non-native species to North America that were first introduced for vegetation control in the 1960s. However, wild-reproducing Grass Carp can negatively impact aquatic habitats and aquatic communities by consuming substantial amounts of aquatic vegetation and increasing turbidity. Numerous fisheries techniques have been used in an attempt to control or eradicate Grass Carp, including electrofishing. However, electrofishing efficiency for Grass Carp has been variable, and optimum electrofishing waveforms and parameters for inducing a capture-prone response have not been determined. The objective of this study was to determine the optimum electrofishing waveforms and parameters...

The goal of this study was to develop a simple, cost effective method to mark fish through oral delivery of an indicator that could be qualitatively and quantitively assessed based on consumption. Our objectives were to 1) determine the concentration of orally administered Sudan Black B required for qualitative confirmation of ingestion, 2) trace the biodistribution of Sudan Black B in several fish tissues, and 3) quantify feed consumption by extracting orally delivered Sudan Black B from several tissues. Additionally, the time required to detect Sudan Black B in each tissue, effects between species, and optimal tissues for Sudan Black B extraction were determined. Methods were developed to quantify absorbance of...

This data set includes acoustic telemetry detection data and biological attributes for walleye and grass carp in the Sandusky River and Bay, OH. The detection data also includes information about the receivers that recorded the detection of acoustic telemetry tags implanted in walleye and grass carp from from 2014 to 2021. Receiver attributes include location and deployment history of each receiver. Detections indicate where and when an individual fish implanted with a unique acoustic telemetry tag was recorded by a receiver. The attributes for each individual fish implanted with a tag and detected by a receiver include biological characteristics, tag details, and post-tagging release location.
In this experimental series we studied the swimming capabilities and response of grass carp (Ctenopharyngodon idella) larvae to flow turbulence in a laboratory flume. We compared three different experimental configurations, representing in-stream obstructions commonly found in natural streams (e.g. a gravel bump, a single vertical cylinder, and patches of submerged rigid vegetation). Grass carp larvae (post gas bladder emergence) were introduce to each experimental configuration and subjected to a variety of hydrodynamic forces of different magnitudes and scales. We varied the flow velocities and water depths and found threshold values of turbulent kinetic energy and Reynolds stresses that triggered an apparent...

This is the qPCR and loop-mediated isothermal amplification (LAMP) data in support of the article "Validation of a portable eDNA detection kit for invasive carps". There are four types of data contained in five files including: limit of detection analysis for each method (qPCR and LAMP), qPCR analysis and LAMP analysis of eDNA samples collected over time from ponds containing 3 or 33 Grass Carp (Ctenopharyngodon idella) mixed with thousands of baitfish. The standards and controls data collected with the eDNA sample analysis are split into separate files for each method to simplify the statistical analysis of the eDNA sample data.

Grass Carp Ctenopharyngodon idella was imported to the United States in the 1960s for research into its usefulness as a biocontrol agent for nuisance aquatic vegetation. Escapees and intentionally stocked individuals founded wild, spawning populations in the Mississippi River and tributaries to the Laurentian Great Lakes. USGS-led research on the Sandusky River, a tributary to Lake Erie, demonstrated spawning of Grass Carp in 2015. In 2018, sampling with ichthyoplankton nets in the Sandusky River 11-13 June produced thousands of suspected fertilized Grass Carp eggs. Genetic analysis of 49 eggs identified by microscopic analysis as Grass Carp eggs confirmed all were from Grass Carp, demonstrating 100% accuracy of...

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...
