Abstract: A portable system for handling and affecting a physiological state of an aquatic species with a pair of gloves, a multiplicity of electrodes, and a pulsator attached to the electrodes, so that when the pulsator is activated the current, alters the physiological state of the aquatic species. The system providing a regulated current output to control the flow of current through the aquatic species held between the pair of conducting gloves.

Abstract: A flexible aquatic species barrier having a multiplicity of pulsators, each pulsator further comprising an anode lead, a cathode lead, and an potential difference generator, where each pulsator is proximately attached to a section of net, each section net comprising a anode conductive braid, a cathode conductive braid, and a net interposed between the anode conductive braid and the cathode conductive braid, and where the anode lead of the pulsator is connected to the anode conductive braid, and where the cathode lead of the pulsator is connected to the cathode conductive braid; whereby when one or more of the pulsators are activated, a potential difference is created between the anode conductive braid and the cathode conductive braid; such that when current flows between the anode conductive braid and the cathode conductive braid an aquatic species is repelled from the net.
