Marine electric fields and fish orientation. 1979

N Pals, and A A Schoenhage

1. Two methods for short-span measurements of DC electric fields in the sea are described. 2. The results indicate a difference between local electric fields (up to 150 muV/m) caused by bottom structures and regional electric fields (up to 60 muV/m) due to electromagnetic processes. 3. The possible relevance of these phenomena to electro-sensitive fishes is discussed.

UI	MeSH Term	Description	Entries
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
D004553	Electric Conductivity	The ability of a substrate to allow the passage of ELECTRONS.	Electrical Conductivity,Conductivity, Electric,Conductivity, Electrical
D004574	Electromagnetic Fields	Fields representing the joint interplay of electric and magnetic forces.	Electromagnetic Field,Field, Electromagnetic,Fields, Electromagnetic
D004594	Electrophysiology	The study of the generation and behavior of electrical charges in living organisms particularly the nervous system and the effects of electricity on living organisms.
D005399	Fishes	A group of cold-blooded, aquatic vertebrates having gills, fins, a cartilaginous or bony endoskeleton, and elongated bodies covered with scales.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
