Mississippi River fishes collected by a suite of entanglement and entrapment gears; 2020-2023

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...

Evaluation of fish behaviors in response to driven and undriven entanglement nets with emphasis on invasive Silver Carp, Central Missouri, 2015-2016

We used Adaptive Resolution Imaging Sonar (ARIS), which is based on Dual-Frequency Identification Sonar (DIDSON) technology to observe net encounter behaviors of bigheaded carps. Gill nets with four different mesh types (8.9 cm bar mesh) and trammel nets with five different mesh sizes (range 5.1-8.9 cm bar mesh) were evaluated. Net sets were undisturbed, or fish were driven with the noise of the outboard boat motor. We sampled field sites in tributaries and the mainstem Missouri River in central Missouri from June 2015 to October 2016. Specific sampling sites were determined based on previously documented Silver Carp abundance with anticipated densities sufficient for testing behavioral responses to entanglement...

Active relocations and tagging data for Black Carp Mylopharyngodon piceus; 2019-2023

This dataset represents active relocations of acoustic and radio telemetry tagged Black Carp among the Mississippi and Missouri rivers near their confluence. These river segments consist of both open river and impounded habitat present during observed hydrologic conditions from 2019-2023. Relocations were primarily on a monthly interval with initial weekly relocations during the first year of the study. Data are available throughout various seasonal conditions to document timing of movements and habitat use in these large rivers.
