Data represent reports of capture of black carp by commercial fishers and biologists with information regarding size characteristics of collected individuals, dimensions of capture gears, and spatial and temporal distributions of captures.

A total of 236 Black Carp were collected throughout the year from 2017-2019 by incidental captures of commercial fishers and biologists. Capture date, river basin of capture location, and coordinates were recorded for each Black Carp captured. A subsample of 119 Black Carp varying from 429-1268 millimeters total length were compared for the precision of annuli counts by two experienced readers for the ossified two anterior pectoral fin rays, the ossified anterior dorsal fin ray, sectioned vertebrae, and lapilli otoliths for selection of a single structure based on percent exact agreement, coefficient of variation, and age-frequency plots.

Black Carp (Mylopharyngodon piceus) were imported to the United States for use as a biological control in aquaculture and have since escaped with reproducing populations in the wild. Habitat use and capture of this species has not been well documented in the wild, thus questions about catchability by gears and habitats are present. This dataset represents sampling effort to capture Black Carp with common large-river gears. Data represent Black Carp catch and the co-occurring catch of Mississippi River fish sampled by the described gears from the lowest reach of the Missouri River and Mississippi rivers near their confluence. Gears consisted of trammel nets, gill nets, and predominately hoop nets fished among mainstem...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
