. .The reproductive cycle and the glycogen content were monitored in the subtidal anemone Sagartia troglodytes (PRICE). Moreover, these parameters were followed for periods of 3 to 30 days over the course of 1 year in anemones previously submerged in stagnant water and thus subjected to a reduced food supply. The anemones showed an annual reproductive cycle with, in contrast to previous studies. 2 spawning cycles. The glycogen content varied between 5 and 8% of the dry weight. Submersion in stagnant water did not alter the reproductive cycle or the glycogen content. Summary In the Oosterschelde the subtidal anemone Sagartia troglodytes showed an annual reproductive cycle with, in contrast to previous studies, 2 spawning cycles; spawning occurred in the periods February to May and July to September. The glycogen content varied between 5 and 8% of the dry weight. Prolonged submersion in stagnant water altered neither the reproductive cycle nor the glycogen content.
