Struktur Populasi Dan Karakteristik Habitat Kerang Kepah (Meretrix Meretrix) Pada Zona Intertidal Desa Teluk Lancar, Kabupaten Bengkalis
Clam Meretrix meretrix is an economically and ecologically significant bivalve mollusk. This study aimed to determine the population structure and habitat characteristics of M. meretrix in the intertidal zone of Teluk Lancar Village, Bengkalis Regency. The research employed a survey method from November-February 2025, focusing on one station divided into three subzones (Upper, Middle, Lower). Results revealed that the sediment substrate was predominantly sandy mud with organic matter content ranging from 0.5% (middle zone) to 2% (upper zone). The highest abundance of M. meretrix was found in the middle subzone (3.1 ind/m²), while the lowest was in the upper subzone (2.0 ind/m²). No significant differences in abundance were observed between stations or intertidal subzones. Size distribution analysis shows that the 2.68-3.17 cm class is the most dominant with 15 individuals. Meanwhile, the 1.18-1.67 cm and 4.16-4.67 cm classes are the least common, each represented by only one individual. The population distribution pattern of M. meretrix itself is uniform, indicating (Id
