Upper Mississippi River mobile split-beam hydroacoustic fishery survey

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.

8 HA_EFF - this tabular dataset details the volume of water sampled by each transducer, at each survey site (wedge_volume_sampled). It also shows the date and start/stop time of each survey, and the start/stop latitude and longitude for each survey. The OP_ID is the unique identifier that ties all three .csv files together. https://iris.fws.gov/APPS/ServCat/DownloadFile/252242?Reference=167571
8 HA_OP - this tabular dataset contains the site information for each survey transect, including the year, month, day, time, the river/water body, the navigational pool or spatial management unit, habitat type, river banks (left or right descending), transect location (nearshore or offshore), the site ID number and the transducer (1/2, surface/downlooking). The OP_ID is the unique identifier that ties all three .csv files together. https://iris.fws.gov/APPS/ServCat/DownloadFile/252244?Reference=167571
10 This is a working document/draft of the USFWS Region 3 mobile hydroacoustics sampling and data processing protocol. We endeavor to keep this document up to date as much as possible, however, Echoview software is constantly improving and certain steps may become redundant or unneccessary. In general this document gives a reasonably accurate description of how the data was collected and processed. https://iris.fws.gov/APPS/ServCat/DownloadFile/252247?Reference=167571

8 HA_FT - this tabular dataset provides information on each fish target, or fish track identified within a survey transect. There is also information on the date/time and lat/long location that a fish was detected, information about fish orientation, depth, distance from the transducer, and fish target strength. Target strength is typically used during analysis to estimate total length. The OP_ID is the unique identifier that ties all three .csv files together. https://iris.fws.gov/APPS/ServCat/DownloadFile/252243?Reference=167571
