Water resources is one that has a high diversity of species. Sampling was conducted at two locations gastropods with each 5 point observations transect with each 5 plots. Diversity of the marine bivalve and Gastropoda in the coastal water painan Panasahan Bay, West Sumatera were studied from December to February Parameter observations include diversity, evenness, density, dominance and similarity, while the physical parameters include water temperature, air temperature, pH and salinity.

These bivalves are hand harvested, for domestic consumption, mainly women and children, with the empty shell sold traders, Intertidal bivalves the economic potential are Anadara antiquata and Gafrarium tumidum clams. The highest diversity index was 2,16 from the Gastropoda group at southern part of Panasahan Bay and lowest was 1,92 from Bivalve group at Northern part of Panasahan Bay.

Analysis of diversity in the village Kumu indeks is 1, 74, while the village of Molas namely 2. This study aims to analyze the diversity of gastropods on mangrove forests in the region of North Sulawesi Bunaken National Park particular village Kumu and Molas.

This research conducted by line transect method gastropodaa was arallel to coastline. The location of sampling had been taken on four stations.

From these results, the index of diversity in the grade being, being classified tastropoda equity index, the indeks for the village of Molas density higher than Kumu village, the next indeks dominance at both locations were classified low, then the indeks of the similarity in the two locations being considered.

The obtained species were identified based on morphological characteristic. Kanekaragaman distribution maen density and diversity of the Bivalve and Gastropoda were difference at each location.

The results showed that of gastropods were found to be composed of 15 species, namely Vexillum sp, Cerithium tenuifilosum, Rhinoclavis kochi, Tectarius muricatus, Partner Coronata, Chicoreus capucinus, Nassarius dorsatus Nassarius distortus, Nerita planospira, Quoyia decollata, Terebralia sulcata, Telescopium telescopium, Faunus ater, Turbo bruneus and Lophiotoma pelytropa.

The results showed that keanekaragamn were 10 Bivalve and 15 Gastropoda species.
