Gracilaria edulis was cultivated in west coast of India off Narakkal by reproductive method
using the carpospores. The culture period was from November to March with regular
sampling of growing plants for the estimation of biochemical constituents, quantitative and
qualitative estimation of agar. The biochemical constituents like protein and carbohydrate
content increased corresponding to the age of the plant whereas the lipid content declined.
Harvesting of the crop can be determined from the qualitative and the quantitative estimation
of agar along with other biochemical constituents. It was found out that crop harvested after
121 days of culture period had better quality of agar and also high protein conten
