Keanekaragaman dan Dominansi Gastropoda di Perairan Pantai Air Salobar Kelurahan Nusaniwe Kecamatan Nusaniwe Kota Ambon

Abstract

Air Salobar Beach has become a tourist location for domestic and foreign tourists. Apart from having a positive impact, the increasing number of tourists visiting has a negative impact on the sustainability of marine biota such as gastropods. This research aims to determine the types of gastropods, diversity and dominance of these gastropods in the coastal waters of Air Salobar, Nusaniwe Village, Nusaniwe District, Ambon City using the transect method. The research location is divided into 2 stations, each station consists of 6 transects and each transect consists of 5 plots with a plot size of 1 x 1 meter. Based on the research results, 12 species of gastropods were found, namely Nerita polita, Nerita maxima, Nerita plicata, Nerita chamaeleon, Nerita squamulata, Thais aculeate, Morula funiculus, Morula margariticola, Lunella cinerea, Conus ebraeus, Vasum turbinellus and Clypeomorus subbrevacula, with a diversity index (H') at station I is 1.81871, station II is 1.16036 and the average is 1.48953 which shows that the H' diversity value is categorized as medium. Meanwhile, the dominance index (C) at station I is 0.203704, station II is 0.386546 and the average is 0.295125 which shows that no species dominates.
