Inside AFS 2015, Portland

Here’s a few pics of electrofishing porn from the American Fisheries Society meeting in Portland, OR, 2015. Lots of new goodies. Enjoy!


Ambient or specific conductivity?

Of all the environmental variables which affect electrofishing success, the one for which the most is known, and indeed it has been said is the most important, is water conductivity. This article explores the how and why of conductivity in electrofishing.

PNAMP Electrofishing Method Template

The Pacific Northwest Aquatic Monitoring Partnership (PNAMP) has produced an Electrofishing Method Template to help standardize how sampling is reported across the region. Researchers can use the template to upload information on their sampling and contribute to the project. The template was originally developed to be customizable in, a website designed to provide consistent documentation of protocols and methods used in research and monitoring.

Standardising by power I

Finding minimum power (voltage and current) levels for effective, successful electrofishing at a sampling site is important for several reasons.

Increasing capture efficiency and sampling precision

As an experienced user, your methodological aims likely include:

  1. develop and standardize species ‘x’ sampling protocols; and,
  2. collect more accurate and precise data to characterize species ‘x’ populations.

If this is the case the Framework for Increasing Capture Efficiency and Sampling Precision is for you. This tool provides a recipe for improving your electrofishing.

The PDF references several Excel worksheets developed by Jan Dean. They can be downloaded on this resources page.


Electrode resistance procedures

This document provides guidance for making electrode measurements on various gear types, using an external power source and an internal power source.Continue Reading..
