Data represent a comparison of herding techniques commonly used by natural resource agencies and the public to increase removal or harvest of invasive carp (i.e., Silver Carp) from U.S. waterways. Sites on lower Perche Creek, Columbia, MO (2018 August 9th to 2018 October 26th) were contained using block nets and treated with one of five herding techniques: (1) method commonly used by commercial fishers in the U.S. (“commercial technique”), (2) pulsed-DC electrofishing (“electric technique”), (3) broadband sound administered with underwater speakers (“sound technique”), (4) both sound and electric in combination (“combination technique”), and (5) solely the boat with no added stimulus (“control”). Sites were administered...

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...

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.
|
These datasets (e.g., 'Starved Rock fish clearing_multi-beam imaging sonar fish data_Pre-clearing_Sonar-s1.csv') include exported information (e.g., fish detection counts) from processed fixed-location multi-beam imaging sonar and mobile side-scan sonar data. Fish abundance in the navigation lock was determined using mobile side-scan surveys, while multi-beam imaging sonars were used to determine fish counts relative to time (i.e., fish per minute). The datasets were used to examine the efficacy of electricity and underwater acoustics, used in tandem, to affect fish abundance (as determined by hydroacoustic data sampling).
