Many fish cannot be harvested with present-day gear because the species are scattered over wide areas. Experiments with pelagic fish show that it may be possible to attract large numbers of fish at night to a series of buoys or rafts with pulsating lights. Then the pulsations would move the fish to a suction hose attached to a factory processing vessel.
