Alternative Stimulation in Fisheries

Summary

The objective of this concerted action is to review current knowledge of fish behaviour and the stimuli to which they react. One aim of the review is to reveal where improvements might be made to current practice in fisheries. Question might be: is there an alternative to heavy ground gears that are thought to damage the sea bed perhaps using sound pulses, electric fields, laser beams or water jets? Why do not all fish small enough pass out through grids and square mesh windows built into codend extensions? It is widely recognized that there is a fund of knowledge about fish behaviour as well as the properties of physical and natural stimuli that is not made use of in applied fishing gear technology.
