Light may be perceived by fish via the eye, the pineal and sometimes the skin. With the characteristics of direction, intensity, wavelength and period, light may be involved in many functions of life in fish (Fig. 1). Direction is probably the most useful attribute since it enables animals to perceive very precisely the direction of food, predators or other members of the species.
