“…The biomass increment of G. gracilis has been associated with higher temperature and longer days; optimal growth has been observed at high water temperatures even up to 30 C (e.g. Choi et al, 2006;Martin et al, 2011). As for several elements (As, Ba, Cd, Cu, Pb, Sr), this interpretation is supported by negative correlations found between their concentrations in G. gracilis and total solar irradiance.…”

“…Gracilaria vermiculophylla most probably has the ability to reattach, but for this to happen it may have to be in contact with a suitable surface long enough to be able to do so. Choi et al (2006) reported that fronds of Gracilaria chorda and G. verrucosa grown on cultivation ropes developed new holdfasts from the parts inserted in the rope (cf. also secondary attachment of Soliera filiformis as described by Perrone & Cecere (1997) and attachment of rhizoids from fragments of Caulerpa filiformis (Khou et al 2007)).…”

Marine macroalgae can expand their distribution ranges by different human-mediated vectors, and certain species traits such as survival time out of water and regrowth of fragments are important factors determining the probability of spread. We tested the survival and capacity of regrowth of the introduced Asian red alga, Gracilaria vermiculophylla, collected in the north-eastern Kattegat, on the west coast of Sweden. Gracilaria vermiculophylla was kept in darkness under moist conditions at 88C for between 4 and 175 days. Following this storage, the shoots were placed in seawater medium (two salinities, 26 and 35) at a temperature of 11.58C. Regardless of the salinity and the duration of the storage, all shoots grew. No correlation was seen between growth rate and storage time, but G. vermiculophylla grew faster in a salinity of 26 than 35. Between two and four weeks of growth, several of the shoots started to fragment. The new fragments continued to grow after detachment. This study showed that G. vermiculophylla can survive long transportations in darkness (e.g. in a ballast tank) and being emerged (e.g. entangled in moist fishing nets).

“…Selama aklimatisasi di tambak, LPH eksplan rumput laut G. verrucosa berada pada kisaran 2,09-3,27%, dan G. gigas pada kisaran 1,61-2% (Gambar 3). Hasil penelitian sebelumnya memberikan informasi bahwa LPH untuk G. verrucosa berkisar 1,59-4,95% dan G. chorda pada kisaran 0,91-4,47% (Choi et al, 2006); Gracilaria spp. pada kisaran 10-12% dan 10,5% (Ren et al, 1984;Hurtado-Ponce, 1990).…”

“…Rumput laut G. verrucosa dapat tumbuh pada kisaran salinitas yang lebar yakni 5-35 ppt, dan tumbuh optimal pada 15-30 ppt (Ohmi, 1958;Choi, 2006). Rumput laut G. verrucosa lebih banyak dibudidayakan di tambak sedangkan G. gigas lebih banyak dibudidayakan di laut, kondisi ini diduga menjadi alasan mengapa respon pertumbuhan rumput laut G. verrucosa lebih baik dari G. gigas pada pemeliharaan di tambak.…”

Abstrak verrucosa dan G. gigas dilakukan dibawah mikroskop. Analisis data pertumbuhan dilakukan dengan uji komparatif independent t-test sedangkan data perkembangan eksplan dan histologi sel rumput laut dianalisis secara deskritif. Pada pemeliharaan di tambak kedua jenis rumput laut memiliki pertumbuhan yang berbeda nyata (P<0,05). Rumput laut G. verrucosa memiliki bobot mutlak lebih tinggi (221,82 g) dari G. gigas (51,94 g) dan LPH (laju pertumbuhan harian) bobot lebih tinggi (3,27%) dari G. gigas (2%). Rumput laut G. verrucosa juga memiliki pertambahan panjang yang lebih tinggi (
