Pale purplish-red, quickly degenerating when removed from the water and becoming distinctly orange; fronds bushy, with a cylindrical axis to1 mm wide and 200 mm long. Both phases readily reproduce vegetatively. Photographs by M.D. Guiry
The red algae Gracilaria edulis, Hypnea valentiae, Acanthophora spicifera and Sarconema indica have been observed to occur and grow in a culture pond. Over a period of eight months, the algae grew to 104 kg in the pond of 800 sq m. The hydrological conditions in the pond are compared to those in the sea containing natural beds of these algae during the period of observations. This occurenceand growth may open up the possibility of growing thses algae in culture ponds providing the requisite hydrological and nutrient conditions.
