The red alga Porphyra (nori) is utilized by humans as a food source throughout the world. In 1992, approximately 15 billion sheets (approximately 45,000 dry metric tons) of Porphyra were produced with an annual value of $1.8 billion (Jensen, 1993). The consumption of nori, long prized by the Japanese, Chinese, Koreans and other people of Asia and the western Pacific as a complement to rice, sushi, soups and salads. Additionally, nori is a staple in macrobiotic diets (Mumford and Miura, 1988), is a source of taurine which controls blood cholesterol levels and a valuable source of phycoerythrin, a red pigment used in the medical diagnostic industry. The consumption of nori in the United States was wholly dependent upon importation from Japan, Korea and China prior to Coastal Plantations International entering the market.
