“…The brown morphotype showed higher growth rates from September to February and lower growth rates from March to August. Over a 12-month period, the average growth rate of the brown morphotype (3.1% day −1 ) was comparable to rates reported for Eucheuma cottonii (K. alvarezii) [2.5-3.5% day −1 (Adnan and Porse 1987), 3-4% day −1 (Mollion and Braud 1993), 3.5-3.7% day −1 (Luxton et al 1987, and2.3-4.2% day −1 (Hurtado-Ponce et al 2001)], indicating its commercial potential as reported by Doty (1987).…”

The three color morphotypes of the red alga Kappaphycus alvarezii (brown, red and green) were cultured in Camranh Bay, Vietnam, using the fixed offbottom monoline culture method to evaluate the growth rate, carrageenan yield, 3,6-anhydrogalactose, gel strength and lectin content. The brown morphotype was cultivated over a 12-month period; the red and green morphotypes were over a 6-month period. At the 60-day culture timepoint, the brown morphotype showed a higher growth rate (3.5-4.6% day −1

“…Another cause could be the site, which was close to the algal ridge and had insufficient protection against waves. The period of minimal growth is similar to that observed by Luxton et al (1987) and corresponds, for Madagascar, to the highest water temperatures (30-33 C; Fig. 1D).…”

Well established populations of Eucheuma denticulatum and E. striatum exist on the coral reef of the south west coast of Madagascar but natural beds are not dense enough to support high harvest pressure. A cultivation test was conducted on a 250 m 2 module using the monoline method with 1560 seedlings of both species for over one year (weighings at 15 day intervals). E. denticulatum and E. striatum showed similar maximum growth rates (2.8 % d -1) occurring respectively in fall and in summer. For both species, minimum growth was observed during the warmest months (February-March). Mean growth rates, although relatively low, showed a high standard deviation, suggesting wide possibilities of strain selection. The preliminary selection experiment led to strains more resistant to breakage and having a growth rate up to 3.3% d-. The 'ice-ice' disease is also present in this area and affects the algae mainly from January to March. Mean carrageenan yield for E. denticulatum was 42.5% + 2.3 and theological properties were above industrial standards, with a highly elastic gel and were thus suitable for commercial applications.

“…Glenn and Doty (1990) reported an average growth rate of 2.0-3.3 % for brown, green, and red strains of this seaweed in Dzilan (Hawaii). Besides, the DGRs obtained in this study were comparable with the DGR of Eucheuma cottonii (= K. alvarezii) reported by Adnan and Porse (1987), Mollion and Braud (1993), and Luxton et al (1987), i.e., 2.5-3.5 % (Indonesia), 3-4 % (Madagascar), and 3.5-3.7 % (Fiji), respectively. Reports encompassing the Indian coast reveal growth rates ranging from 2.45 to 7.64 % for K. striatum (= K. alvarezii) at Okha, northwest coast (Mairh et al 1995), and growth rate ranges of 0.34 to 5.5 % at Mandapam, southeast coast of India (Eswaran et al 2002).…”

Cultivation of Kappaphycus alvarezii was carried out at Okha, northwest coast of India, from August 2004 to April 2006, using the raft and net bag methods. Seawater temperature, salinity, nitrate, and phosphate varied seasonally, with average values of 26.51±1.72°C, 34.23±1.79‰, 17.46±8.77 μM L −1 , and 1.32±0.78 μM L −1 , respectively. After 15, 30, and 45 days of growth, average daily growth rates (DGRs) were 6.87±0.27, 5.99±0.18, and 4.97±0.08 % with corresponding biomass of 292.43 ± 12.06, 629.58± 32.56, and 977.98 ± 36.59 g FW plant −1 , respectively, for the raft cultivation. In the net bag method, after 15, 30, and 45 days of growth, the mean DGRs were 7.88±0.38, 5.83±0.10, and 4.42±0.14 % with biomass values of 348.98±19.48, 623.28±29.95, and 813.73±52.64 g FW plant −1 , respectively. This study confirmed the feasibility of cultivating K. alvarezii on the northwest coast of India.
