A refined electrofishing technique for collecting Silver Carp: Implications for management. Supporting data The table provides all fish collected using two different electrofishing methods at Illinois River sites in 2012 and 2013. Length and weights were taken on most species and gender was taken from Silver Carp. Fishes were categorized whether they were netters (caught by nets) or jumpers (jumped in the boat while sampling) and only netters were used in analyses. Large numbers of shad were collected in 2013 and an additional spreadsheet includes abundance data in an aggregated form for those sites. The data is not sensitive/classified and there are no legal restrictions on who may obtain or use the data.

The purpose of the study was to quantify the effectiveness of stream-road crossing restoration (culvert replacement to the stream simulation standard) in terms of numbers of fish and length of stream gained through restoration, and to quantify the continuing...

Catches of walleye (Sander vitreus), clupeidae, and moronidae are tallied by mesh size and net type at each deployment site. More detailed information about net construction and methods is provided in the accompanying Fisheries Research article.

Surveys are conducted along transects, transects are divided horizontally into successive intervals, and then within an interval there are multiple successive depth layers. Area backscattering (ABC), mean acoustic size (sigma), and fish density are reported for each unique transect-interval – layer from Lake Michigan in the years 2011-2016. Area backscattering (PRC_ABC), mean acoustic size (sigma), and fish density in the intervals and layers of acoustic survey transects of Lake Michigan in the years 2011-2016. The survey is carried out using a...

It is the longest known continuous trawl survey in Lake Erie. In addition to spanning over 50 years, the data series is unique for three prominent design elements: 1) sampling was conducted at three depth strata; 2) replicate trawl samples were collected at each depth stratum; and 3) sampling was conducted during both day and night. Unlike other trawl series collected in Lake Erie, and throughout the Great Lakes, the East Harbor program is the only one to combine these sampling practices in a single survey. In 2012, the original vessel used since the inception of the East Harbor...
