Assessing the Efficacy of Single-Pass Backpack Electrofishing to Characterize Fish Community Structure
—Two-pass backpack electrofishing data collected as part of the U.S. Geological Survey’s National Water-Quality Assessment Program were analyzed to assess the efficacy of single-pass backpack electrofishing. A two-capture removal model was used to estimate, within 10 river basins across the United States, proportional fish species richness from one-pass electrofishing and probabilities of detec...
متن کاملSingle-Pass versus Two-Pass Boat Electrofishing for Characterizing River Fish Assemblages: Species Richness Estimates and Sampling Distance
—Determining adequate sampling effort for characterizing fish assemblage structure in nonwadeable rivers remains a critical issue in river biomonitoring. Two-pass boat electrofishing data collected from 500–1,000-m-long river reaches as part of the U.S. Geological Survey’s National Water-Quality Assessment (NAWQA) Program were analyzed to assess the efficacy of singlepass boat electrofishing. T...
متن کاملEstimating Habitat-Specific Abundances of PIT-Tagged Juvenile Salmonids Using Mobile Antennas: A Comparison with Standard Electrofishing Techniques in a Small Stream
The use of passive integrated transponder (PIT) tags in ecological studies is increasingly common, but evaluations of their performance and range of application in the field are still emerging. Here, we compare habitat unit–scale abundance estimates of PITtagged juvenile coho salmon Oncorhynchus kisutch and steelhead O. mykiss derived from multiple-pass surveys with a submersible pole-mounted P...
متن کاملEffects of Electrofishing Gear Type on Spatial and Temporal Variability in Fish Community Sampling
—Fish community data collected from 24 major river basins between 1993 and 1998 as part of the U.S. Geological Survey’s National Water-Quality Assessment Program were analyzed to assess multiple-reach (three consecutive reaches) and multiple-year (three consecutive years) variability in samples collected at a site. Variability was assessed using the coefficient of variation (CV; SD/mean) of spe...
متن کاملMovement and Capture Efficiency of Radio-Tagged Salmonids Sampled by Electrofishing
Electrofishing-based estimates of fish abundance are common. Most population models assume that samples are drawn from a closed population, but population closure is sometimes difficult to achieve. Consequently, we individually electrofished 103 radio-tagged trout of two species, westslope cutthroat trout Oncorhynchus clarkii lewisi and brook trout Salvelinus fontinalis, in five streams in west...
