Description Observations made for one year on the seasonal changes in growth, reproduction
and spore output of Gracilaria foliifem and Gracilariopsis sjoestedtii
are given. These red algae occurred only a few months during the year in the area
of study. Maximum growth of G. foliifera was during April and of G. sjoestedtii
was during September and January-March. Tetrasporophytes were more abundant
than carposporophytes in G. foliifera, whereas in G. sjoestedtii carposporophytes
occurred more. Maximum outputs of tetraspores and carpospores were recorded
on the tirst day, and the period of peak shedding of spores coincided with the
peak growth period of these seaweeds. There was, however, no definite rhythm of
diurnal spore output.
