Southeastern blue suckers and other large benthic fishes were collected via electrofishing (720-1000 volts, 8-8.5 amps) for periods ranging from 15 to 30 min (depending on the extent of suitable habitat; i.e., some sample sites were too big to sample in 15 min), with most of the effort focused in high current areas near woody debris (Peterson et al, 1999; Mettee et al, 2004).
In my former career as a fishery biologist, I always marveled that a good percentage of lunkers we caught by electrofishing in early spring had the tails of big gizzard shad (10 to 12 inches) sticking out of their gullets.
We assessed whether common sampling techniques, backpack electrofishing and angling, could reliably detect the presence and determine abundance estimates of the species in wadeable tributary streams of the Athabasca River.
This was at the same time that another electrofishing crew had been sampling intensively in the same reaches.
As part of a study of factors influencing their recruitment, juvenile largemouth bass were sampled in 1996 using daytime seining and electrofishing surveys on five Ohio reservoirs: Caesar Creek, Delaware, Knox, Pleasant Hill, and Tappan.
During the daylight hours of a 1-wk period in September 1992, two electrofishing surveys were conducted along the entire shoreline of the study area to collect fall YOY.
Shedd Aquarium Director of Water Research Andy Casper brought the other group for electrofishing down the creek that feeds into the Fox River.
Sampling gears consisted of either a combination of tote barge electrofishing and seining 300 m reaches (i.e., KDWPT and COW) or only seining in all available habitats for approximately 1 h (i.e., Perkin et al., 20156 and this study).
Bass and walleyes were collected using electrofishing from May through September in each of two years, and stomach contents were removed using gastric lavage (non-lethal stomach flushing).
Fish species composition and relative abundance (catch-per-unit-of-effort or CPUE is the number of fish/minute of electrofishing effort) data were gathered by performing electrofishing surveys at each river reach using a model 6A Smith-Root boat-mounted electrofisher.
