Abstract

Growth and fruiting behaviour of the populations of Gracilaria edulis, Gracilaria foliifera and Gracilariopsis sjoestedtii are described based on the field studies conducted from January 1969 to June 1971 in the Palk Bay near Rameswaram. Populations of these three agar-yielding red algae have been observed throughout the year with two half yearly growth cycles, one from October/ November to April and the other from May/June to September. The rale of growth was found to vary in the growth cycles. Plants with reproductive structures occur in Gracilaria edulis and Gracilaria foliifera in all months of the year and in Gracilariopsis sjoestedtii for a short period from November to March. Variations observed in the abundance of sexual, asexual and sterile plants and the abnormal features noticed in the reproductive behaviour of these three algae have been discussed.
