To help evaluate population control and migration deterent efforts, the U.S. Fish and Wildlife Service conducts mobile hydroacoustics surveys in 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 Bighead and Silver Carp.  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.\",\"shortAbstract\":\"The U.S. Fish and Wildlife Service conducts mobile hydroacoustic surveys in the Upper Mississippi River to estimate relative abundance, size distribution, spatial distribution, and biomass of Bighead and Silver Carp.

Transducers are pointed towards the thalweg when sampling all habitat types, and are calibrated on-axis periodically throughout the survey time period.  Main channel / main channel border habitats have their sampling area divided into either nearshore or offshore transects along each bank.  The nearshore main channel sampling area occurs at the 1 to 1.5 m depth contour.  The offshore main channel sampling area is located farther from shore, picking up where the beams from the first transect would have hit the bottom and viable data collection would have stopped.  In areas where wing dams extended out into the channel, transects went over the top of the dams if water depths were sufficient, or data collection was paused at the dam, the survey vessel navigated around the dam, and then resumed data collection on the other side close to where collection had previously stopped.  Side channel habitats have only nearshore transects available on each shoreline.  Backwater lakes and other off-channel habitats are sampled with one or more transects on each shoreline (depending on size).  Main channel and side channel habitats are subsampled using randomly selected 1/2 mile long transects.  Data from backwater lakes or tributaries will also be reported in 1/2 mile increments, but for backwaters the entire shoreline is sampled, and for tributaries, when accessible up to 2 miles of tributary may be sampled.
