QUICK-START GUIDE TO ELECTROFISHING Jim Reynolds1 and Lisa Harlan2 This guide provides fisheries personnel with essential information necessary to initiate satisfactory electrofishing — that is, a safe, effective electrofishing operation with minimal stress and injury to fish. This information applies to all types of electrofishing (e.g., boat,
LR-24 Electrofisher - Smith-Root. You, a Fisheries Biologist, called for a lightweight backpack electrofisher with precise digital controls, "quick setup" options, and the ability to store and recall electrical settings.
This piece of equipment was ahead of its time when introduced and continues to revolutionize the field of electrofishing. The Smith-Root exclusive "Quick Setup" function allows users to simply place the electrodes in the water to allow the backpack to quickly assess the water conditions and set appropriate electrical settings. Therefore, LR ...
A moderate water conductivity is most efficient for electrofishing (see graph above) because it uses a moderate amount of current and voltage to successfully catch fish. Further, the conductivity of a fish is in this moderate part of the range, and therefore, electrical current flows through the water and fish very efficiently at these conditions.

Electrofishing acts as a deterrent by identifying these invaders but also helps monitor the expansion and contraction of their range in portions of the stream. Although electrofishing has been used to evaluate stream health for decades, there's recently been a what-if-in-the-world wonderment about another technique, and that technique is ...

This setup uses a default setting of a pulsed DC waveform with a frequency of 30 Hz and a 12% duty cycle (equivalent to a 4ms pulse width). All settings can be adjusted up or down from this starting point to achieve levels necessary for fish capture. This is very useful when electrofishing in a new area and you're not sure what settings to use.
Electrofishing, broadly defined as the use of electricity to capture or control fish, was envisioned in an 1863 British patent application by Isham Baggs. Not until the 1920s, when large, stationary generators were available, did electrofishing applications (i.e., fish barriers) begin. After World War II, applications of electrofishing for ...
AC electrofishing with "chase boats" (boats behind the electrofishing boat) in deep water habitats is often used to sample catfishes (Porreca et al. 2013). Sampling the Milwaukee River with multiple backpack electrofishers. On wadeable streams, selection of electrofishing gear is usually determined by stream size. Backpack electrofishers are ...
electrofishing method. If density estimates are not found to be sufficiently accurate then consideration should be given to other sampling approaches.
