Sargassum beds are abundant in the coastal waters fronting the municipalities of Borongan and Lawaan, Eastern Samar. The study aimed to identify the species composition and to determine the extent of Sargassum beds in the two coastal areas. Using the transect line quadrat method, three sampling stations were established in each study site. The extent of the Sargassum beds in Borongan was 57,904.45 sq. m. while in Lawaan the extent value was 56,723.9 sq. m. Results of the study showed at least 5 species of Sargassum were found in the coastal water of Borongan and 6 in Lawaan. A higher total number of thalli were found in Borongan, with 1354, compared to Lawaan, with only 1011. Species diversity indices showed that Sargassum species are more diverse in Lawaan. However, a high similarity index was calculated and a minimal interval in evenness was measured. Acceptable results were obtained in the analysis of the physico-chemical parameters. This signifies, together with the abundant Sargassum beds, that the coastal waters are capable of supporting and sustaining aquatic life. dela Cruz, Margarita T. adviser.
