Cryptogams: Algae. Most mentioned species listed above occur on the coasts of Indonesia, Malaysia, Singapore, Vietnam and the Philippines, fewer species have been recorded from Burma (Myanmar), Thailand and Papua New Guinea. Journal of Applied Phycology Only male plants were available for examination. By the 1980s S. micracanthum and S. okamurae, temperate Sargassum species, dominated in Tosa Bay, but in the 1990s the distribution of these two species became Danilo B. Largo. The proposed new species is known only from Panay and Palawan islands in the western central Philippines. List of Sargassum species.

Maximum growth was achieved after 6 months, reaching a mean length of 42.8 ± 30.9 cm (max recorded was 1 m), some cultivars starting to show signs of senescence. Sargassum gracillimum Reinbold. 91, pp. However, reports on its culture are non-existent. In addition, the vertical distribution and dominant species of seaweeds on the two islands were very similar, but the functional-form composition of seaweeds at Nachido Island differed slightly from that at Odo Island. Assessing and validating Sargassum species records and distribution in northern Philippines. Introduction. Upon close inspection, it is easy to see the many leafy appendages, branches, and round, berry-like structures that make up the plant.

This review paper presents information on the production status of economically important seaweed species in the Philippines, new culture technologies for Halymenia durvillei and also an examination of the present but limited use of Sargassum.The country recorded its highest production volume of seaweeds (mainly eucheumatoids) in 2011 amounting to 1,840,832 metric tons (fresh weight). Four species of Sargassum in Negros Island, central Philippines, were monitored for biomass, growth stages, alginate yield and quality.

Sargassum is a genus of brown (class Phaeophyceae) macroalgae in the order Fucales.Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species.

Species identification Sargassum muticum is a large brown seaweed, varying in colour from dark brown to pale, yellowish brown depending on the season and the growing conditions. Other seaweeds with economic importance are Codium, Gelidiela acerosa, Halymenia, Porphyra and Sargassum spp. Seaweed biomass exhibited an even distribution across the shore gradient from the high intertidal zone to -5-m depth at Nachido Island, whereas seaweed biomass was concentrated from the mid intertidal zone to -1 m depth in the subtidal zone at Odo Island.

These are based on collections made on the spot during an ecological survey on the Sargassum -dominated seaweed communities in the locality. Sargassum thunbergii was the most dominant species, occupying 28.24% (114.12 g wet wt/m2) and 36.57% (99.05 g wet wt/m2) of total biomass at Nachido and Odo Islands, respectively. 480 fish species identified in the gulf, 131 or 27% are seaweed-associated or these fishes have utilized the seaweed habitat for juvenile settlement, refuge, breeding and feeding sites. California Sea Grant College, La Jolla, CA, USA. Sargassum stenophyllum (Mertens) Martius possess a flexible frond, ≈40 cm long, which is stirred by About 1,100 species occur here in the Philippines, nearly 30% of which are endemic.

Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. These are mainly producedthrough gathering of natural stocks. Subdominant seaweed species was Gelidium amansii, comprising 15.23% (61.52 g wet wt/m2) and 14.70% (39.82 g wet wt/m2) of total biomass at Nachido and Odo Islands, respectively.

In conclusion, this study demonstrated the feasibility of farming S. siliquosum from hatchery-produced seedlings using suspension culture method to produce biomass for commercial use. Coastal Marine Science 35(1): 182-201. Further studies on anaerobic digestion conditions of the selected seaweeds that are suitable for utilization by island communities should also be conducted.

This study describes the culture of S. siliquosum from land-based hatchery to out-planting in the open sea. We also include a review of Sargassum floras from Samoa, Tonga, and Nauru and discuss species distribution in the southwest and central Pacific.
