There are a number of useful instructional videos housed on a server at the National Conservation Training Center (U.S. Fish & Wildlife Service). The videos, while still valid, are a few years old now, and likely will be updated or supplemented in the next year or two.
Some of these videos are the same as those housed in Vimeo with links listed elsewhere on electrofishing.net. Depending upon your connection, the Vimeo versions may have better resolution. However, to access videos on this list, you don’t need an account or password.
Electrofishing Techniques: A very brief overview of 5 electrofishing gear deployments: metal-hulled boat, tow-barge, shore-based, backpack (2), and raft. (1 minute)
Electrofishing Essentials: A set of instructional videos on topics including waveforms and their fish-catching attributes, taking proper water conductivity measurements, building standardized output tables, estimating equipment operating capacity (effective range of water conductivity), equipment operation, and trouble-shooting. There is a comprehensive safety module as well.
Electrofishing Safety: Addresses 3 areas: safety features of equipment, safe operation, and personal protective gear. (24.5 minutes)
Wader Safety: Covers general wader safety, filmed with above and below-water cameras in a swimming pool. Also outlines a wader safety training program. Produced by Utah State University. (14.5 minutes)
Boat Continuity Check: Introduces the use of a multimeter to check continuity of metal surfaces within an electrofishing boat. All metal surfaces should be in electrical continuity to lessen the risk of shock. Dave Knuth, Missouri Department of Conservation. (41 seconds)
Backpack Troubleshooting: Your backpack is not working. This video runs through the troubleshooting steps while you’re in the field.
Water Conductivity Measurements: Distinguishes between two types of conductivity measures and which one applies to electrofishing. (7 minutes)
Backpack Operation: Discusses operation of three common backpack electrofishing units. (11.25 minutes)
Electrode Resistance: Covers techniques to measure electrode resistance and to analyze for problems. The external battery approach is helpful, provided you only have a basic multimeter. Preferably instead, read your control box meters directly or use testing equipment (scopemeters, current probe) discussed in other blogs on this site. (16 minutes)
Calibration of a Backpack Electrofisher: Procedures to check output and meter accuracy of a backpack electrofisher using a scopemeter, a peak-reading multimeter, and a current probe. Also presented is an analysis of maximum outputs versus expected. (24 minutes)
Current Probe Use in Field: A brief on using a current probe on a backpack electrofisher electrode. (15 seconds)
Pulse Width Adjustment: See changes to the pulse width of a pulsed direct current waveform generated by electrofishing equipment. NOISY! There is engine noise so be sure to turn your speakers down! (1.25 minutes)
Voltage Adjustment: See changes to the peak voltage level of a pulsed direct current waveform generated by electrofishing equipment. NOISY! There is engine noise so be sure to turn your speakers down! (31 seconds)
Pulse Width and Voltage Adjustment to a “Rounded Waveform”: See concurrent changes to voltage and pulse width in a pulsed direct current waveform generated via a silicon-controlled rectifier used in such equipment as the Smith-Root, Inc. Type VI and GPP models. (12 seconds)
Fish Behavior in Electric Fields: A classic but still useful video outlining fish behavior and neurological factors behind observed responses. Work was done in lab experimental tanks at the Biarritz Station of Applied Hydrobiology in France. (18.5 minutes)
Inhibited Swimming Response: Inhibited swimming of a gar in an electric field using a lab experimental tank. (5 seconds)
Taxis (attraction) Response: Attraction of a gar to the anode under the influence of an electric field generated in a lab experimental tank. (21 seconds)
Immobilization Response: Immobilization of a gar under the influence of an electric field generated in a lab experimental tank. (6 seconds)
Fish Immobilization Threshold Experiment: Part of an experiment to determine electrical immobilization thresholds for northern snakehead. (1.25 minutes)
