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.

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 data was collected by the US Fish and Wildlife Service to see if environmental DNA (eDNA) varied across pools and within pools in the Illinois River basin. The data was collected in 2015 from three different habitat types: shoreline, main channel, and bays. The resulting data were then analyzed using an occupancy model.

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).

Dataset contains sampling information (site, location, and date of sampling) for largemouth bass and silver carp captured in La Grange Pool of the Illinois River during 2015 used to determine the population size structure of both species for analyzing size-specific feeding of largemouth bass on young-of-year and Age-1 silver carp. The dataset also contains information on fish prey items found in largemouth bass stomachs for diet analysis.

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.

Complete ISO 19115 FGDC metadata can be found under the hosted view feature layer on the FWS AGOL platform.
