Karakteristik Habitat Dan Kelimpahan Kerang Darah (Anadara Granosa) Di Zona Intertidal Sepahat Kecamatan Bandar Laksamana Kabupaten Bengkalis

Coastal areas play a vital role as habitats for various aquatic organisms, including the economically valuable blood cockle (Anadara granosa), which also serves as a potential bioindicator of environmental quality. However, habitat degradation caused by coastal abrasion, pollution, and mangrove destruction along the Bengkalis coast may affect the abundance and A. granosa. This study aimed to identify the habitat characteristics and abundance of A. granosa in the intertidal zone of Sepahat Beach and to analyze the relationship between sediment organic matter content and cockle abundance. Sampling was conducted using line transect and quadrat methods across three intertidal subzones (upper, middle, and lower). Water quality parameters such as temperature, salinity, and pH were measured in situ, while sediment fractions and organic matter content were analyzed in the laboratory. The results showed that temperature ranged from 31–32°C, salinity from 29–32 ppt, and pH from 6.0–6.25, which are within the optimal range for A. granosa. Sediments were dominated by sandy mud, with the highest organic matter and cockle abundance found in the middle zone (3.2 ind/m²). Statistical analysis revealed a strong positive correlation between sediment organic matter and cockle abundance (r = 0.81). These findings indicate that A. granosa prefers fine, organic-rich sediments that provide stable conditions for feeding and burrowing. This study provides baseline data for the sustainable management and conservation planning of blood cockle habitats in Bengkalis coastal areas.
