In Part A of this blog, it was calculated from a lab study that the effective conductivity of Grass Carp was 62 uS/cm. In Part B, let me show you a simple way of using that information in the field to improve the capture success of Grass Carp based on those results. You may want to download the Electrofishing Tool or App from the Tool section of this site.
This blog is being presented it two parts. Part A involves the lab trials to determine Grass Carp effective conductivity, Cf, and power density at match, Dm. Refer to prior blogs at this site on the power transfer theory and on lab experiments for more information about terms, setup and procedures.
What is your electrofisher ammeter telling you? The obvious answer is that it is indicating amperes of electrical current flow, the movement of electrical charges past a point or surface. But not all electrofisher ammeters display the same measure of current, and that can and does lead to confusion.
