Gastropods and edible macroalgae

Abstract

The study on gastropods on edible macroalgae was conducted at Kodingareng island on the west-side of South Sulawesi. Macroalagae of the genera Hypnea, Gelidium and Acanthophora were sampled together with their molluscan fauna. A total of 36 genera of gastropods were found on the three genera of algae. The genera Heliacus, Clypeomorus, Cerithium, Pyrene, Columbella, Mitra, and Morula were present on all three genera of algae. Cerithium and Rhinoclavis were the most common hervivores on Gelidium and Hypnea, while Littorina was the most common herbivores on Acanthophora.
