BookAQ Hurtado & RF Agbayani - 2000 - Aquaculture Department, Southeast Asian Fisheries Development Center
Series: Aquaculture extension manual; No. 32A 24-page manual that introduces the carrageenan-producing seaweed Kappaphycus whose culture has spread from Jolo in Mindanao to at least 14 sites in the Visayas and Luzon. Four culture methods are presented: fixed off-bottom, raft long-line (single or multiple), hanging long line, and polyculture of seaweeds with carnivorous fishes.

Proceedings of the Symposium on Culture and Utilization of Algae in Southeast Asia, 8-11 December 1981, Tigbauan, Iloilo, Philippines, 1990 - Aquaculture Department, Southeast Asian Fisheries Development CenterDifferent seaweeds harvested from natural stocks are utilized in Thailand as human food and animal feed and for medicinal purpose and extraction of crude agar. Gracilaria and Porphyra are the most exploited commercially. Commercial cultivation through seaweed farming is recommended.
Carrageenan properties and proximate composition of three morphotypes of Kappaphycus alvarezii Doty (Gigartinales, Rhodophyta) grown at two depths AQ Hurtado-Ponce -
Botanica Marina, 1995 - Walter de GruyterThree morphotypes (brown, green and red) of Kappaphycus alvarezii grown at two depths were evaluated for carrageenan properties and proximate composition. The green morphotype was significantly different from the brown and red in all carrageenan properties except for sulfate content at 50 cm below the water surface; and significantly different only from the brown at 100 cm. Except for ash content and nitrogen free extract there were no significant differences in proximate composition (nitrogen, crude protein, crude fat, crude fiber) among the three morphotypes.
