This study investigated the various seaweed farming methods in Western Visayas, Philippines. Data were gathered through workshops, focus group discussions (FGD), key informant interviews (KII), and secondary sources, and were subsequently analyzed. Results showed that four out of six provinces in the region serve as the major suppliers of fresh and dried seaweeds namely, Antique, Iloilo, Guimaras, and Negros Occidental. The eucheumatoids species widely farmed in production sites across Western Visayas include Kappaphycus alvarezii (Doty) L.M. Liao 1996, K. striatus (F. Schmitz) L.M. Liao 1996, and Eucheuma denticulatum (N.L. Burman) Collins and Hervey 1917. Although farming techniques vary per province and mainly rely on culture sites, the simple long line (fixed-off bottom and floating line) is the most common method utilized throughout the region. Other methods employed are broadcast, floating bamboo raft, spiderweb, octopus, and single vertical floating (tumbo-tumbo). Significant roles and activities performed by key actors and the enabling environment were discussed. While seaweed production in Western Visayas is still considered a minor industry, the documentation and analysis of the present farming methods and status of seaweed production are crucial in crafting initiatives and strategic directions for improving the quality and production of eucheumatoid farming in the region. Efforts to boost eucheumatoid production include research focused on improved spore production, nursery establishment, and utilization of tissue culture technologies. These strategies will ensure a sufficient supply of healthy seaweed seedlings for culture. Capacity building and promoting best aquaculture practices (BAP) to key stakeholders are also vital for proper coordination and optimizing programs, projects, and initiatives that foster a supportive environment for seaweed farming in the region.
