“…Seaweeds are the raw material for many industrial productions like agar-agar, alginate derivatives and carrageenan but they continue to be widely consumed as food in Asian countries. [1] Nutrient content of seaweeds vary with species, geographical location, season, humidity and temperature. [2] They are nutritionally valuable as fresh or dried vegetables, or as ingredients in wide prepared foods.…”

ABSTRACT. Proximate composition of the three green seaweeds viz., Chaetomorpha aerea, Enteromorpha intestinalis, Enteromorpha compressa one brown seaweed Dictyota dichotoma and one red seaweed Gracilaria corticata was investigated by determination of protein, carbohydrates, lipid, moisture and ash content. In the present study, the total protein was recarded upper most in E. intestinalis and bare minimum in E. compressa. The maximum carbohydrates recorded in C. aerea and minimum in G. corticata. The lipid content was acquired upper limit in E. compressa and least in C. aerea. The ash and moisture content in following of 5 different seaweeds are as follows: 7.45mg/g, 3.91mg/g were recorded in the C. aerea, 8.52mg/g, 3.42mg/g in the E. intestinalis, 8.58mg/g, 3.75mg/g in the E. compressa, 9.47mg/g, 4.23mg/g in the D. dichotoma and 6.95mg/g, 3.98mg/g in G. corticata. The proximate composition of 5 different seaweed species exhibited high nutritional value for human consumption.

“…More recently, its use as flakes and in various cooked foods is becoming more widespread (e.g., Rhatigan 2009). Various aspects of chemical composition have been evaluated including lipid content (Mishra et al 1993) and antioxidants (e.g., Yuan et al 2009, Cornish andGarbary 2010). There are two traditional areas for the commercial harvesting of P. palmata in eastern Canada: Grand Manan Island in New Brunswick, and Digby Neck in Nova Scotia (e.g., Ffrench 1974).…”

Population ecology of Palmaria palmata is described from the intertidal zone of Digby Neck and adjacent islands of Nova Scotia. The primary objectives were: to evaluate the difference in habitat specialization and population structure of P. palmata between harvest and non-harvest shores, and to characterize differences in thallus structure and frond sizes between epilithic and epiphytic populations. Harvest shores were gently sloping boulder fields with boulders typically about 0.5-1.0 m with dense cover of P. palmata on many of the rocks. Non-harvest shores (with or without P. palmata) consisted of boulders that were smaller or larger than harvest shores, or bedrock; when P. palmata was present on nonharvest sites it was typically epiphytic on other algae (e.g., Fucus spp., Mastocarpus stellatus, Devaleraea ramentacea). Harvestable epiphytic populations occurred only in high current areas. While there was little difference in average cover of P. palmata harvest and non-harvest shores (31.2 ± 13.7% vs. 19.4 ± 7.3%, mean ± standard deviation [SD]), the cover of P. palmata on harvest shores was highly skewed such that individual boulders often had >90% cover while adjacent rocks had little. Frond length of large fronds was greater on harvested shores, and mean frond density (g m -2 ) was three times higher than the mean density on the non-harvested shores. Frond lengths of entire epiphytic and epilithic frond complements of 119 thalli from harvest beaches showed no difference in mean size of the largest fronds, and no difference in frond number per holdfast when epiphytic and epilithic thalli were compared.Key Words: Digby Neck; Dulse; Nova Scotia; Palmaria palmata; Palmariales; population ecology; seaweed harvesting INTRODUCTIONThe red alga Palmaria palmata (Linnaeus) Weber et Mohr is widely distributed in the cold waters of the North Atlantic and Arctic Oceans (Irvine and Guiry 1983, Bird and Van der Meer 1993, Guiry and Guiry 2011. Despite its cold water affinities, P. palmata occurs in warm temperate waters far south as New Jersey in the western Atlantic Ocean (Taylor 1957) and Portugal in Europe, with localized large populations in northern Spain (Faes and Viejo 2003). Throughout its range P. palmata may be an epiphyte, and it typically occurs in the low intertidal and subtidal zones to depths of about 20 m (Irvine and Guiry 1983, Faes and Viejo 2003, Vadas et al. 2004).In eastern Canada P. palmata occurs from the Bay of Fundy through to the Gulf of St. Lawrence and the island of Newfoundland (Taylor 1957, Edelstein et al. 1970, Wilson et al. 1979, South and Hooper 1980, South et al. 1988. In the outer reaches of the Bay of Fundy, this species can become abundant, and it forms the basis of commercial harvests (MacFarlane 1964, 1966, Ffrench 1974, Chopin and Ugarte 2006.

Abstrak Makroalga termasuk salah satu sumberdaya hayati laut yang banyak terdapat di perairan Indonesia. Makroalga memiliki potensi besar untuk dikembangkan, karena memiliki peranan penting baik dari segi ekologis maupun ekonomis. Tujuan penelitian adalah untuk mendapatkan informasi mengenai struktur komunitas makroalga yang ada di perairan Desa Mata Kecamatan Kambowa Kabupaten Buton Utara. Penelitian ini dilaksanakan pada bulan Desember 2014-Januari 2015. Metode yang digunakan adalah metode kuadran ukuran 1x 1 m 2 yang diletakkan pada garis transek sepanjang 100 m dengan interval 10 m. Makroalga yang ditemukan 17 spesies yang terdiri atas Kelas Chlorophyta berjumlah 7 jenis, kelas Phaeophyta 3 jenis dan kelas Rhodophyta 7 jenis. Komposisi jenis makroalga didominasi oleh kelas Chlorophyta (39%), Kelas Phaeophyta (37%) dan kelas Rhodophyta (24%). Indeks keanekaragaman makroalga sekitar 2.058 dikategorikan sedang, indeks keseragaman sekitar 0.726 dikategorikan tinggi dan indeks dominansi 0.198 dikategorikan rendah.Kata Kunci: Makroalga, komunitas dan keanekaragam Abstract Macroalgae is one of the marine biological resources that are found in Indonesian waters. Macroalgae has great potential to develop, because it has an important role both in terms of ecological and economical. The study aimed to obtain information on the community structure of macroalgae in Mata village water, Kambowa districts, north buton district south east Sulawesi. The study was conducted in December 2014-January 2015. The method used in study is a sampling squares transect 1x1 m 2 and other is 10 m distance and 100 m lenght. The observation was found that the number of macroalgae spesies consisted of 17 species consisting of chlorophyta class 7 species, phaeophyta class 3species dan rhodophyta class 7 species. The composition was dominated by chlorophyta class (39%), phaeophyta class (37%) and rhodophyta class (24%). Density of macroalgae with a value of 2.058 which is the category was based on the index of diversity, uniformity value amounted to 0.726 with a high category indexes based on uniformity while for dominance with value amounted to 0.198 and low dominance categorized based on the index of dominance.
