A reference to the production of electricity by living organisms which usually refers to the electricity-generating ability in some aquatic creatures; such as, the electric eel, electric catfish, and to a lesser extent the black ghost knifefish.

The fish that utilize such bioelectrogenetic aspects often also possess electroreceptive abilities (which are more widespread) as part of an integrated electric system.

The bioelectrogenetic skills may be utilized for self-defense, electrocommunication, and with the stunning of prey.
