Design of Artificial reef in Chile Masatoshi FUTAGAWA / CORDUNAP May 22, 2012 1. Functions of Artificial reefs (AR) Formation of flora and fauna Algae larvae will attach to AR which was carried by current after installation of artificial reef (AR), and the larvae grow with nutrition in water and sunlight. Water current stagnated by AR and grown algae, and sediment attach or settle on AR, the sediment gives more nutrition to algae, and flora is formed around AR. The algae harbor fish larvae and juveniles and feed annelids (worms), arthropods (copepoda, crabs, shrimps), herbivorous and omnivorous fishes. Those animals feed carnivorous fish including pelagic fish that stays above AR then form fauna. Moreover, some of fish and finfish use AR for spawning ground and close life-cycle at AR. High productivity Productivity depends on production of algae which relate to nutrition of water, sunlight, current and design of AR (height, width, thick...
