USGS Bottom Trawl Sampling on Lake Erie
Detailed Description
The U.S. Geological Survey Great Lakes Science Center has conducted lake-wide surveys of the fish community in Lake Erie since the 1960s. The resulting data on relative abundance, size, and age of fishes are used by state and provincial agencies to manage Lake Erie fish stocks. This video shows bottom trawl sampling during June 2015.
