J. Agardh. The brown seaweed Sargassum siliquosum is among the most common species with economic potential in the Philippines. Upon close inspection, it is easy to see the many leafy appendages, branches, and round, berry-like structures that make up the plant. Main axis short, up to 8.5 mm long, with up to seven primary branches, crowding at its tip. In: Ohno M, Critchley AT (eds) Seaweed cultivation and marine ranching. Journal of Applied Phycology Habit of fertile material; b. The authors are greatly indebted to Ms. Marilyn Dayao for the. The Philippines, home to one of the most diverse Sargassum resources in the western Pacific basin, has more than 40 species of Sargassum. Twenty-one species of seaweeds were identified from the materials collected in Maqueda Bay and vicinities, and in Western Samar during February-December 1994. examined first to conclude this proposition, and, outlined by Chiang and others (1992), particularly the branched horizontal stolons. (Fucales, Phaeophyta) in Bolinao, Pangasinan [Philippines] those by Modelo and Umezaki (1995) were reported to bear female receptacles. This study describes the culture of S. siliquosum from land-based hatchery to out-planting in the open sea. Dominant functional group was the coarsely branched-form group, which grows under moderate environmental conditions and comprised 93.34% (377.15 g wet wt/m2) and 66.96% (181.35-g wet wt/m2) of total biomass at Nachido and Odo Islands, respectively.

For a period of 16 months, growth of S. siliquosum in the hatchery tanks was very slow, but became faster when out-planted in open sea using suspension culture method. just below the tip; cryptostomata numerous, vertically attached, oblong, up to 30 mm long, 9 mm wide; margin entire at the, basal 1/3 especially at the adaxial portion of the leaf, becoming serrate-dentate or, sometimes duplicated towards the tip; apex rounded, sometimes obtuse; base. meal in the Nile tilapia Oreochromis niloticus.

The seaweed species, Sargassum spp., Turbinaria spp., Hydroclathrus spp., Caulerpa spp., and Ulva spp., which can allow sustainable biomass supply either through managed harvesting of natural stocks or through cultivation, have been identified. The compound has a wide range of food production applications such as emulsifying, stabilizing, gelling and thickening agent (P, also used in paint, textile, paper and plastic manufacturing industries (e.g. Studies on the taxonomy of the genus Sargassum (Phaeophyta) and the phenology and some aspects of the ecology of S.

The authors would like to thank the Bureau of Fisheries and Aquatic Resources (BFAR) for encouraging this project under its National Seaweed Development Program; the Municipality of Liloan (Cebu Province, Philippines), through the Municipal Agriculture Office, for hosting the pilot Sargassum farm in its municipal waters; and the assistance of Liloan’s Bantay Dagat (Sea Watch) team who made sure our pilot farm is not disturbed by intruders. 27 mm long, 5.5 mm wide; base asymmetrical; margin serrate-dentate; apex rounded. dentate; apex rounded or obtuse; midrib apparent, disappearing near the tip; 3 mm long and 3 mm wide; lumpy due to scattered and elevated cryptostomata. 2. a.
