Resumen

La almeja de manglar Pegophysema philippiana Reeve, 1850, es común en los sustratos fangosos de los manglares en Baganga, Davao Oriental, particularmente en los barangays de Kinablangan, Lucod, Salingcomot y Bobonao. El muestreo se realizó del 2 al 7 de mayo de 2022, durante la marea alta. La relación longitud-peso de las almejas de manglar se calculó mediante la ecuación exponencial W = aLb. Se recolectaron un total de 769 almejas de manglar durante el muestreo. Las almejas más grandes (4,4 ± 0,81 cm) y más pesadas (43,4 ± 25,3 g) se registraron en Bobonao, las más pequeñas se midieron en Lucod (3,7 ± 0,65 cm), y las almejas más ligeras se encontraron en Kinablangan (26,8 ± 16,28 g). El ANOVA detectó diferencias significativas (p < 0,05) en la longitud y el peso de las almejas de manglar entre los distintos sitios. La relación longitud-peso de la almeja de manglar exhibió una fuerte relación positiva entre la longitud y el peso; sin embargo, se observaron diferentes valores de pendientes. Esto es muy común en los bivalvos porque son muy sensibles a los cambios ambientales. En general, la relación longitud-peso de la almeja de manglar en Baganga, Davao Oriental, reveló un patrón de crecimiento alométrico.
