Abstract
    Seagrass beds are indispensable components of an aquatic realm. Dasol is among the coastal municipalities of Pangasinan that support the province's need for cheap and sustainable food and livelihood. Recognizing the preponderance of the ecosystem in this municipality, an assessment was conducted to determine the status of the seagrass beds and their associated macrobenthic fauna and to identify further management strategies to sustain their productivity. Sampling sites were established in the barangays of Tambobong (station 1) and Uli (station 2). The transect-quadrat method was employed with triplicates and laid out perpendicular to the shoreline. Meanwhile, economic benefits and disturbances were determined through face-to-face interviews with local government officials. The results revealed that higher seagrass percent cover, shoot density (sd), and relative density (rd) were recorded in Tambobong. Likewise, Tambobong recorded higher estimates of biomass for most seagrass species. In terms of associated macrobenthic fauna, Tambobong harbors a higher number of species belonging to three classes: Porifera (11%); Echinodermata (33%); and Mollusca (56%), with an overall estimated density of 1.400 individual m-2. However, environmental quality did not differ between sampling sites. Economic benefits include gleaning and tourism. These activities may have caused disturbance to seagrass beds, as mentioned by the local officials.
