ABSTRACT
This study aims to determine the distribution pattern and diversity of gastropods in the Intertidal Waters of the Eastern District of Rupat. The study was conducted in February 2022. The study location consists of 3 stations each station was placed 3 transects from the highest tide to the lowest tide with different distances. Along the transect line, 3 plots with a size of 3 x 3 m were placed and each plot contained a subplot with a size of 1 x 1 m. The results of the study show offer gastropod species consisting of 9 families, 12 genera, and 13 species. The distribution pattern at the study location was clustered with the diversity index value (H') at a moderate level of diversity. The highest abundance of gastropods was found in the coast Sukarjo Mesim Village (station I) with an abundance value of 25,600 ind/ha and the lowest abundance was in the coast Teluk Lecah Village (station III) with an abundance value of 11,100 ind/ha, while the highest abundance of gastropods between subzones was in the upper zone with an abundance value of 20,400 ind/ha and the lowest abundance was in the lower zone with an abundance value of 12,200 ind/ha. The highest relative abundance was the species Indothais javanica with a relative abundance value of 18.30%, while the lowest relative abundance was the species Oliva ornata with a relative abundance value of 0.85%. Temperature 29-30oC; salinity 28-30 ppt; pH 5-6; DO 5.2-6.4 mg/l. The total organic matter content of the sediment is 0.46-23.33%. sediment type at station I dominated by mud, station II dominated by muddy and station III dominated by sand, with total organic matter content of the sediment is 0.46-23.33%.
Keywords: gastropods, distribution, diversity, Eastern Rupat District.
