Seaweed Cultivation
The ever increasing demand of the raw material and depletion of natural stock necessitates the cultivation of commercially important seaweeds like Gracilaria edulis, an important agarophytes of India.
The culture practice of Gracilaria is being carried out either from Fragments or from spores

Cultivation of Gracilaria edulis from Spores
Cultivation of Gracilaria edulis from spores is a new method. CMFRI has sucessfully cultivated G.edulis from spores at Mandapam. For the first time it was carried out at Kochi where there is no natural vegetation of G.edulis
Different growth stages of Carpospores
