Abstract
Kappaphycus alvarezii (Doty) Doty from the Philippines was grown in the subtropical waters of Shikoku Is., Japan (33°26′35″ N, 133°25′00″ E). The growth rate, carrageenan yield, viscosity and gel strength were compared to values for plants cultured in the Philippines and between spring-summer, autumn-winter and winter periods in Japan. Maximum daily growth rates up to 8% occurred in Japan in October to November (autumn) while die-back occurred in winter due to low seawater temperature (15 °C). The average growth rate (ca 5%) in spring-summer to autumn was comparable to that in the Philippines. During the winter (December), the daily growth rate was approximately 1%. Gel strength, determined in a 1.5% solution in both water and 0.2% KCl, was 850 g cm-2 and 2000 g cm-2, respectively. Sol viscosity was 890 cP at 75 ° C. These values are quite similar to values obtained in the Philippines.
