Struktur Populasi Kerang Lokan Polymesoda Expansa Pada Hutan Mangrove Di Desa Banglas, Kabupaten Kepulauan Meranti

---

Lokan (Polymesoda expansa) is a bivalve that lives in mangrove forest areas and has important ecological and economic values. The lokan population plays a role in maintaining water quality and is a source of livelihood for coastal communities. This study aims to analyze the abundance, distribution patterns, and frequency distribution of individual sizes of P. expansa in the mangrove forest of Banglas Village, Meranti Islands Regency. The research was conducted in December 2024 using a survey method with the determination of station locations by purposive sampling. Sampling was carried out at three stations, each consisting of three transects with plots measuring 1×1 m². The results showed that the highest abundance was found at Station III (5.44 ± 1.837 ind/m²) and the lowest at Station II (2.77 ± 0.692 ind/m²). The distribution pattern of lokan at all stations is clustered (Morisita index value>1). The frequency distribution of individual sizes showed the dominance of sizes 3.40-3.89 cm with a total of 21 individuals. Abundance and distribution patterns of lokan are influenced by habitat conditions, human activities, and food availability. ANOVA test results showed no significant differences in abundance between stations, but there were significant differences between subzones. Knowledge of the population structure of P. expansa is important for sustainable resource management in mangrove ecosystems.

Keywords: abundance, distribution pattern, individual size, Mangrove forest Polymesoda expansa.
