Title

Diversity and abundance of echinoderms in Pancuran Beach, Lembeh Island

Abstract

Echinodermata are found quite commonly in the tidal areas of Lembeh Island but their diversity and abundance have not been well documented. The purpose of this study was to determine the types of Echinoderms and their abundance at Pancuran Beach, Lembeh Island, Bitung City. Samples were taken at two stations using the Lincoln-Smith Transect method 2 x 50 m which was stretched perpendicular to the beach with three replications. Samples were identified in situ and the number of individuals of each species was noted. The results showed that in Pancuran Beach there were 18 species of phylum Echinodermata; with details of 7 species from the Asteroidea class, 5 species of Echinoidea, 4 species of Ophiuroidea, 2 species of Holothuroidea. The results of the analysis using the diversity index show that the diversity of Echinodermata at both stations is in the medium category, characterized by the value of H' = 2.06 for station I and H'= 2.35 for station II.  At station 1, the type of Ophiocoma erinaceus has the highest density of 15 ind/100m² and a relative abundance of 23.68%. At station II Echinothrix diadema has the highest abundance of 12 ind/100m² with a relative abundance of 17.14%. Common species found in both stations are Diadema setosum, Echinometra mathaei, Echinothrix diadema, Holothuria atra, Ophiocoma erinaceus, and Ophiocoma scolopendrina.
