Deep sea farming of seaweeds is feasible and profitable. This was found in studies done by researchers Anicia Hurtade and Renato Agbayani of the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC AQD) in Tigbauan, Iloilo. Seaweed farming is commonly done in shallow water but the marine crops are subject to excessive grazing by herbivores such as rabbitfish (danggit), sea urchins and starfish.
