As an experienced user, your methodological aims likely include:
- develop and standardize species ‘x’ sampling protocols; and,
- 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.
Dr Alan Temple introduces the key concepts and methods of operating various backpack electrofishing units.
Dr Alan Temple introduces the key concepts and methods of assessing the safety of boat electrofishing units.
A voltage gradient probe is used to measure and map electrical fields produced by electrofishing units. It can be a valuable tool for assessing and standardising electrofishing equipment.
In this video, Alan Temple describes how to use a multimeter to trouble-shoot a malfunctioning backpack unit.
The following description covers basic trouble-shooting tasks that can be performed in the field. Some companies also publish in-depth trouble-shooting guides for testing control boxes and branch circuitry. Always obtain trouble-shooting guides from the manufacturer of your equipment, if available.Continue Reading..
As fish lovers and conservationists, we have a vested interest in maintaining fish health. As fisheries scientists, we have the responsibility of ensuring that our sampling techniques are as ethically transparent and non-invasive as possible. Many of us have moved from passive gear types, such as gill nets, to what are considered ‘less harmful’ methods, such as electrofishing. Continue Reading..
