Data tables represents a telemetry study assessing the efficacy of sound and electricity used to herd Silver Carp (Hypophthalmichthys molitrix). The study occurred in Jonathan Creek Embayment of Kentucky Lake, Kentucky using 10 telemetered Silver Carp and 46 passive acoustic receivers. Two herding boats traveled at 2.22 meters per second along bank-to-bank transects through the study area (longitudinal progression rate = 0.37 meters per second) emitting sound and electricity (“stimulus”) or no added stimuli (“control”). Fish movement responses included fish presence in the refuge-zones located at either end of the embayment, fish presence fore of herding boats, and fish presence within 100 meters, 200 meters, 400...
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...

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...
