Abstract: The assessment was conducted from September to November, 2018 to provide baseline information on the population status of mangrove clam, Polymesoda erosa in the estuarine areas of Pasak River, Sasmuan, Pampanga. Transect-quadrant method was employed in the collection of clam samples from the three established study sites. Results revealed that no significant variations on the spatial density, size structure, growth pattern and condition index of the mangrove clam in the study areas (p>0.05). Generally, the biological parameters indicate low density, unimodal to bimodal size distributions, negative allometric growth, and very low condition index which suggest poor condition of mangrove clam population in the study sites. The information derived from the condition index analysis is useful in identifying future brood stocks in the hatchery operations and future management directions to help increase clam population in the area and sustain its economic contribution.
