Heather Calkins made her way to the Great Lakes State this month to complete the FWS National Conservation Training Center’s Principles and Techniques of Electrofishing Course. Alan Temple and Jan Dean led the week long class at the West Shore Community College near Ludington, Michigan. The duo had a great way of helping folks understand sampling with electricity and its usefulness in the fisheries field, while keeping it entertaining. They performed an interesting experiment finding the threshold power settings to elicit a desired response in sea lamprey using just a backpack shocker, fish tank, two metal plates and lively specimens. This simple experiment provides valuable insight into how species react differently to various electrical intensities and waveforms and in turn what settings would be most effective for targeting certain species.
