Hydroacoustic data from central Lake Erie, 2021

Hydroacoustic estimates of fish density are used for fisheries management in central Lake Erie. Hydroacoustic data were collected along 10, randomly-selected, 5-kilometer transects and two cross-basin transects between the US and Canadian shorelines in central Lake Erie during July 2021. Software-generated raw variables were used for calculating estimates of hydroacoustic fish densities presented here in tabular form. These data are related to a longer-term data set from 2010-2019, and a data set from 2020.
