Dataset Description
The U.S. Fish and Wildlife Service conducts mobile hydroacoustics surveys in select pools of the Upper Mississippi River (UMR) and other associated tributaries and water bodies, to obtain data on the relative abundance, size distribution, spatial distribution, and biomass of invasive Bighead and Silver Carp in order to evaluate mangement actions. Data are collected with two horizontally oriented split-beam transducers (200 kHz; BioSonics, Inc.) offset in angle to maximize water column coverage. Surveys occur at main channel, side channel, backwater and tributary habitats. Hydroacoustic data are typically paired with physical capture data that are collected by the USFWS and/or partner agencies. A separate data management plan exists for hydroacoustic-related physical fish sampling.
