The gymnocyst is more developed proximally and marked with defined pores. This is probably in large part because of both the popularity throughout the Pacific Rim of Gracilaria as a food, and the fact that the seaweed is generally eaten raw or lightly alkali treated, often with raw fish. Extraction of Gelidium species gives the higher quality agar, as measured by the strength of a jelly formed by a 1.5% solution. Basic care.. Gracilaria is mainly cultivated and harvested for agar production, currently providing more than 50% of the world’s supply of agar. Encrusting mainly on Sargassam sp. One of the keys to success in propagating Gracilaria is to keep the algae in constant motion within the water column. Under bright lighting it will FLUORESCE a deep red colour. Sulfated polysaccharides (PLS) extracted from the marine algae of the genus Gracilaria showed biological activity in different inflammatory models, except for periodontitis. It is easily cared for, doing well in low light. The initial symptoms of the three Gracilaria food poisonings involving G. verrucosa and Gracilaria chorda in Japan in 1980, 1982, and 1993 were nausea, vomiting, stomach pain, and diarrhea.
