Distribution and Diversity of Gastropod and Bivalve (Mollusca) in the Mangrove Ecosystem of Bukit Batu Village, Bukit Batu District, Bengkalis Regency

---

The mangrove ecosystem is a distinctive ecosystem found along coastal areas and river estuaries, influenced by the ebb and flow of seawater. Only a few organisms can thrive in such environments, with one such group being mollusks. Two classes of the phylum Mollusca with the largest number of species are Gastropoda and Bivalvia. This research aims to identify, analyze the abundance, diversity, and distribution patterns of gastropods and bivalves (mollusks) in the mangrove ecosystem of Bukit Batu Village, Bukit Batu District, Bengkalis Regency. The study was conducted using a survey method. Station 1 was located in the Industrial Plantation Forest (HTI) area, station 2 in the mangrove ecosystem area, and station 3 in the residential area.The abundance of gastropods across all stations ranged from 1.89 to 9.44 ind/m2, with the lowest average at station 1 (1.89 ind/m2) and the highest at station 3 (9.44 ind/m2). Bivalve abundance averaged between 0.33 and 0.56 ind/m2 across stations. The gastropod abundance in sub-zones averaged between 3.56 and 6.78 ind/m2, with the highest in the upper sub-zone and the lowest in the upper sub-zone, while bivalve abundance between sub-zones averaged between 0.11 and 0.89 ind/m2. The highest diversity index was recorded at station 1 (1.92), while the lowest was at station 3 (1.73). The distribution pattern of observed objects in the research location was predominantly clustered, with a grouping pattern observed across all stations.The average organic matter content was highest at station 3, reaching 45.92%, and lowest at station 1, amounting to 32.09%, in line with the low abundance of gastropods and bivalves at station 1.
