The dataset consists of count data derived from a series of sonar images. The data are fish counts per image from 1) a computerized process to extract fish counts, and 2) three manual assessors. Each image has a total of four associated fish counts.

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 hydrology and water temperature on dam passages by bigheaded carps using a complementary log-log model for continuous-time processes to estimate a Cox proportional hazards regression model (Allison 2010).

This is collection of multiple datasets for bighead and silver carp from the the Illinois, Ohio, and MIssissippi rivers. This data was collected by researchers, monitors, and managers between 1997 and 2018. Jahn Kallis created this dataset by combining these individual datasets.

In the Lamine, Moreau, and Little Chariton rivers, light traps were used to capture larval bigheaded carps moving into tributaries. Traps were set on a weekly basis in each river, at roughly 1-kilometer intervals up to 7 km upstream. Ichthyoplankton tows were done in locations near the confluence of each tributary with the Missouri River, and within the Missouri River itself. Data includes identification of larval fish, size, and developmental information of subsampled invasive carp species. Flow readings were taken at up to five points across the channel with a Marsh-McBirney flow meter, and water quality was measured at the surface with a YSI ProPlus before retrieval of light traps.

An eDNA-based sampling approach used by the U.S. Fish and Wildlife Service for bigheaded carp Hypophthalmichthys spp. in the upper Mississippi River and Great Lakes Basins that collects hundreds of water samples per event. The U.S. Fish and Wildlife Service detected a single positive sample for bighead carp _H. nobilis_ during the spring 2021 sampling event in the Kinnickinnic River within the Milwaukee River Basin, and detected a second single positive sample for bigheaded carp during the fall 2021 sampling event in the Milwaukee River. The U.S. Fish and Wildlife Service did not detect any bigheaded carp or bighead carp in previous years (2015 to 2020) or in either the spring or fall 2022 sampling events. These detections lacked perspective such as detection numbers for other species. We reanalyzed the 2021 and 2022 samples for four existing species of fish: two fairly common species (common carp Cyprinus carpio and gizzard shad Dorosoma cepedianum) and two fairly rare species (burbot Lota lota and grass carp Ctenopharyngodon idella). This dataset contains the eDNA-base detection and nondetection data from the 2021 and 2022 sampling events.

In September 2023, the USGS demonstrated the use of side-scan sonar to image large densities of invasive carp in Creve Coeur Lake, Maryland Heights, Missouri, USA. A 400-meter reach was surveyed using a Humminbird Helix sonar system. Proprietary sonar data were converted to PNG image files (i.e., rectified and speed-corrected) using SonarTRX Pro. The resulting data set includes one CSV file, original side-scan sonar images (PNG files), speed corrected side-scan images (correcting distortions in imagery due to small changes in boat velocity; PNG files), and a KMZ file of original rectified images for a mosaic display in Google Earth Pro.

The invasive carp environmental DNA (eDNA) sample data was collected and processed by the U.S. Fish and Wildlife Service (USFWS) and is used for the early detection and monitoring of invasive carp. The reportable eDNA detection summary data along with static maps are shared with the public along with a public facing ArcGIS Online Feature layer, Web Map, and Dashboard. For further information on data collection and processing please refer to the Quality Assurance Project Plan eDNA Monitoring of Bighead and Silver Carps (see files and links). Additional information on the Invasive carp eDNA program for the U.S. Fish and Wildlife Service can be found on the Whitney Genetics Lab Facility web page (see files and links). A positive eDNA detection result means there was invasive carp eDNA in the water body, which can be from live or dead fish, but it could have also been transported via boat, bird, or water current. A positive eDNA detection does not necessarily mean there were invasive carp present at the time samples were taken. For more information or questions, please contact the eDNA Program Coordinator, Nick Frohnauer at (nicholas_frohnauer@fws.gov). Complete ISO 19115 FGDC metadata can be found under the hosted view feature layer on the FWS AGOL platform.

This dataset represents fish targets (presumed Silver Carp, Hypophthalmichthys molitrix) recorded using Adaptive Resolution Imaging Sonar (ARIS; Sound Metrics, Bellevue, WA) in five backwater embayments of Kentucky Lake and Lake Barkley, KY (2022 February). A surface-to-bottom block net was set across embayments in a “chevron” shape pointed upstream to guide fish movements downstream through net openings (about 15 m wide) along each shoreline and within sonar range for quantification. Fish targets were enumerated then subsampled for length measurement using a systematic random approach.

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 recorded at the time of tagging. The shipping industry and barge movement data were also included in summaries to evaluate how traffic around these navigation barriers may be preventing or assisting fish movements. To ensure data were being collected with confidence, periodic field testing of the acoustic receiver were performed and included in the final study materials.
