Illumination system

A system for illumination of aquatic animal food which has been dispensed into a volume of water, the system comprising:

• a feeding system, external to the volume of water, for dispensing food for the aquatic animals into the volume of water, whereby the food, once in the volume of water, travels in an overall average travelling direction, said overall average travelling direction defining a feeding axis in the volume of water;
• a first illumination surface positioned in the volume of water and arranged to illuminate the feeding axis, the first illumination surface for emitting a first light in a first direction towards the feeding axis;
• a second illumination surface positioned in the volume of water and arranged to illuminate the feeding axis, the second illumination surface for emitting a second light in a second direction towards the feeding axis;
• wherein the first illumination surface and the second illumination surface are different surfaces and are arranged to emit light towards the feeding axis from substantially different directions;
• to thereby illuminate the food as the food travels in the direction of the feeding axis;
• and,
• wherein the volume of water has an air surface and wherein the feeding axis is substantially normal to the air surface.
