Experiments on cultivation of economically important seaweeds such as Gracilaria edulis, Gelidiella acerosa, Sargassum spp and Turbinaria spp have been carried out during the past few years at the Central Marine Fisheries Research Institute. A suitable technique of culture of the agarophyte Gracilaria edulis has been developed. Technique for culturing the other seaweeds have not yet been streamlined. The culture technology developed for G. edulis comprises of introduction of small fragments of the seaweed into the twists of the coir rope fabricated in the form of nets and tied to the fixed poles in the inshore waters and monitoring their growth.
