Tension changes in body of bream Abramis brama (L.) in homogenous electric field in relation to flow direction of direct current and to total length of fish

Abstract

Body tension of bream Abramis brama (L.) in homogenous electric field of DC current in relation to direction of current flow and to fish length had been investigated under aquarium conditions. It ascertained that, threshold tension values in body depend on initial position of fish in relation to force lines of electric field and an increase of value in body tension under particular reactions is proportional to length of fish.
