Hairati Arfah, Simon I Patty

Abstract


Research on biodiversity and biomass of macroalgae in Kotania Bay waters, West Seram, Mollucas was conducted on July and August 2010. There were 20 species of macroalgae collected, in which 8 species were green algae (Chlorophyceae), 6 species of brown algae (Phaeophyceae), and 6 species of red algae (Rhodophyceae). The highest biomass of algae were collected in Loupesi, as much as 127,01 g/m2, followed by Burung Island (119.42 g/m2), Wael (63.43 g/m2), and the lowest were found in Buntal Island (20.64 g/m2). The macroalgae found in sampling area were dominated by Halimeda, Padina and Sargassum. The highest biomass were found on Sargassum duplicatum (570.00 g/m2), Halimeda opuntia (271.33 g/m2), Gracillaria crassa (198.13 g/m2), and Sargassum crispivallum (178.00 g/m2).

 

Keywords: Macroalgae, biodiversity, biomass, Kotania Bay, West Seram.

ABSTRAK

Penelitian tentang keanekaragaman dan biomassa  makro algae di perairan Teluk Kotania, Seram Barat, Maluku telah dilakukan pada bulan Juli dan Agustus 2010.  Algae yang dikumpulkan sebanyak 20 jenis, terdiri dari 8 jenis algae hijau (Chlorophyceae), 6 jenis algae coklat (Phaeophyceae) dan 6 jenis algae merah (Rhodophyceae).  Biomassa algae tertinggi ditemukan di Loupesi yaitu 127,01 g/m2 dikuti Pulau Burung 119,42 g/m2, Wael 63,43 g/m2 dan terendah di Pulau Buntal 20,64 g/m2. Algae yang dominan adalah Halimeda, Padina dan Sargasum. Biomassa tertinggi diperoleh pada jenis Sargassum duplicatum (570,00 g/m2), Halimeda opuntia (271,33 g/m2), Gracilaria crassa (198,13 g/m2), dan Sargassum crispivallum (178,00 g/m2).
