How to record EODs
Here I lay out how I record the electric organ discharges (EODs) of mormyrids and offer some advice on how you can do so yourself. This is written with mormyrids in mind, but most of this will also hold for recording EODs from gymnotiform fishes in Central & South America. What I know about EODs and recording them I've learned from Professor (now Emeritus) Carl Hopkins of Cornell University and from experience on more than one dozen field trips to Africa. I'll update this article as needed to keep it current and maximally helpful. Feel free to leave your comments or questions.
