This article is a summary of Chapter 9, Cultivation and Domestication of Kappaphycus alvarezii Strains at Ubatuba Bay, Sao Paulo State, Southeastern Brazil, from an e-book entitled Tropical Phyconomy Coalition Development: Focus on Eucheumatoid Seaweeds, written by various authors.
The authors reported that different colors and strains of seaweed seedlings may produce different yields of carrageenan. Semi-refined carrageenan yields of EP gametophytes were higher than those of tetrasporophytic strains. All strains showed lower yields in May and higher from August to December. The same goes for refined carrageenan. We should conduct a similar study on the cultivation of Kappaphycus alvarezii in Indonesia.
