SEA CAGE CULTURE SYSTEM USING NIGHT ILLUMINATION

摘要

PURPOSE: A sea cage culture system using night illumination is provided to attract different animal plankton(or zoo plankton) in each season as natural, animal food for fishes being raised in the sea cage culture and thus, to raise healthier, high-quality fishes. CONSTITUTION: The sea cage culture system using night illumination includes the steps of: growing the fry to 2-3cm by feeding artificial assorted feed in a nursery facility on land; transferring the fry to a cage culture built on the coast and installing lights for night time around the cage to attract animal plankton as natural, animal food for the fry; and raising the fry until the fry become big enough to be sold as high-value added products. In each season, different kinds of animal plankton are attracted to the night illumination which in turn creates more natural feed for the fry.
