Shell Dimension-Weight Relationship and Condition Index of the Invasive Mussel Mytella strigata in Sasmuan, Pampanga, Philippines

A total of 300 Mytella strigata were collected at three sampling points in the mussel coastal demonstration farm Sasmuan, Pampanga, and subjected to morphometric gravimetric measurements for evaluation its growth pattern condition index. Designated sites based on distances river mouth (200 m, 400 600 m) with varying water quality parameters (temperature, salinity, pH, velocity, chlorophyll-a). Mussels Site 2 had significantly larger shell dimensions (SL = 2.862 cm, SW 1.458 SH 0.926 cm), weight (0.640 g), live (1.150 g). Significantly higher (p < 0.05) soft-tissue dry (0.083 however, was obtained 3, while comparable >0.05) soft tissue observed (0.364 g) 3 (0.413 Nevertheless, mussels all demonstrated negative allometric (b 3). The length-weight relationship revealed a weak moderate, positive correlation. index which could have been influenced by chlorophyll-a substantially lower velocity. As such, this signifies potential well-established population spatial distance (600 from mouth. Hence, regular harvest product development is recommended as strategic options control proliferation.
