The annual occurence of “gulaman-dagat” seaweed (Graci-'aria confervoides) in Philippine marine waters, especially along the shallow shores of Manila Bay, was first reported by Seale in 1911. The heavy season of this particular seaweed begins from January to the latter part of June every pear. The report of Collado (1926)2 on the nutritive properties of seaweeds, mentioned gulaman-dagat as a possible source of commercial agar and food as well. The amount of gulaman-dagat, found annually along the shallow shores of Manila Bay is enough to supply a home industry for bleaching and drying the seaweed for commercial purposes.
