Abstract

Ecologically intertidal mollusk has important role in the food chains. As a filter feeder, mollusk is also known as a food source for other marine organisms. The intertidal zone is known as the smallest area in the ocean basin (Nybakken, 1992). This zone is a narrow edge cover only few square meters and position between low tide mark (LTM) and high tide mark (HTM). The study was conducted in Mokupa beach waters, Tombariri sub-district, Minahasa Regency. Coastal area of Mokupa village represent typical tropical ecosystem such as coral reef, seagrass bed and mangrove belt. As many as 45 species in 134 total individuals were recorded during the study. The density of gastropods collected is 4.4667 individual/m2 while density for gastropods species Littoraria scabra Linne was 0.4000 individual/m2 and in term of relative density is 9.834 % and thus considered the highest. Species diversity index of this species is H’ = 2.37594. Keywords: mollusk, diversity, dominance   A B S T R A K   Secara ekologis Moluska yang menempati daerah intertidal memiliki peranan yang besar kaitannya dengan rantai makanan. Karena di samping sebagai filter feeder, moluska juga merupakan makanan bagi biota lainnya. Zona intertidal (pasang-surut) merupakan daerah terkecil dari semua daerah yang terdapat di samudera dunia (Nybakken, 1992). Zona ini merupakan pinggiran yang sempit sekali, hanya beberapa meter luasnya, terletak di antara air pasang tinggi dan air surut rendah. Penelitian ini dilaksanakan di perairan pantai Mokupa Kecamatan Tombariri Kabupaten Minahasa. Daerah pantai Desa Mokupa merupakan daerah yang lokasinya terdapat ekosistem yang khas di daerah tropis yaitu terumbu karang, padang lamun, dan hutan mangrove.

Abstract

This study aims to determine the density and relative density of gastropods and diversity index of the community as well as evenness and dominance index in the intertidal beach Malalayang), Manado in North Sulawesi. Gastropods were sampled using quadrate with size 1x1m2 placed systematically and disproportionately on dead coral sandy substrate, mix mud, rocks slightly sandy substrate, and  substrate-sized stones. The study found that there has been a change in the amount of 30 species of gastropod species (Manginsela, 1998) increased to 69 species. While the density of gastropods contained in the intertidal beach of Malalayangis ranging from  13,63individu / m2to currently 2,73-13,63individu / m2 and relative density ranging from 11.22% - 42.78%. Diversity index of organism is high with a value of H '= 2.81497. Evenness index of gastropods in Malalayang Beach intertidalcould be categorized fairly even and almost evenly. Meanwhile, the low dominance values ​​C = 0.2132, indicating that the area has good conditions as a place to live, and yet there is competition, which means, food or a place is suitable for gastropods to live. The intertidal area of Malalayang Beach Manado North Sulawesi substrate are mainly in the form of sandy coral, slightly muddy and rocky.
