This data release includes hydroacoustic data for the 2021 to 2022 water years at four stations. These stations are part of a discrete and continuous monitoring project in embayments on Long Island Sound to support nutrient management activities in Connecticut. The data were collected by the U.S Geological Survey (USGS) in cooperation with the Connecticut Department of Energy and Environmental Protection. The data were collected using acoustic doppler current profilers (ADCPs) sampling 134 parameters every six minutes. Recorded values above the water surface were removed from files using an R script. The ADCPs were deployed at upstream and downstream locations in the Mystic and Norwalk embayments. For the Mystic...

Field observations of water and suspended-sediment fluxes at the Golden Gate were made over one ebb tide and one flood tide on three occasions: 1) 21-22 March 2016, following a large storm event that triggered the first flow into Yolo Bypass flood control structure since 2011; 2) 23 June of 2016, during a period of low freshwater inflow and 3) 27-28 February 2017, following several large storms of the wettest winter in northern California in recorded history. On each occasion, flux of water and suspended sediment were estimated using data from a boat-mounted acoustic Doppler current profiler. This instrument provided high-resolution velocity and acoustic backscatter (ABS) data at a cross-section (“transect”) near...
Hydroacoustics is a common sampling tool in freshwater and marine ecosystems, yet the full potential of this tool remains restricted, owing to an incomplete understanding of the influence of many data collection settings. In particular, investigation into the effects of the pulse duration setting on common hydroacoustic measures remains limited. Hydroacoustic theory suggests that pulse duration can affect how many single targets (e.g., individual fish or invertebrates) are detected, the mean target strength (TS) of sample cells, and estimates of target density, especially in ecosystems with an abundance of potential targets. To quantify the influence of the pulse duration setting on these important and commonly...

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...

This dataset includes exported hydroacoustic data (i.e., coordinates for acoustically detected fish targets, mean target strength of detected fish). The distance (m) from the water guns for each fish target was calculated using the gps coordinates of fish targets and the water guns’ location. The total lengths of fish targets were estimated from their target strength (dB), and fish were then classified as native fish or bigheaded carp according to their total length. This dataset was used to examine the efficacy of water guns to alter bigheaded carp behavior via analyses on fish abundance, spatial and size distribution of fish, and the effective water gun range. Each worksheet tab is labeled with the survey date...

This project addressed regional climate change effects on aquatic food webs in the Great Lakes. We sought insights by examining Lake Erie as a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate hypoxia and reduce habitat volume for some species. We examined fish community composition, fine-scale distribution, prey availability, diets, and biochemical tracers for dominant fishes from study areas with medium-high nutrient levels (mesotrophic, Fairport...
