Abstract

This study investigated the diversity of seaweed species in correlation with the physicochemical characteristics of the marine water in Clatagan, Batangas. Seaweeds identified were Acanthophora spicifera, Caloglossa leprierii, Gracilaria blogetti, Gracilaria heteroclada, Gracilaria salicornia, Laurencia papillosa, Padina australis, and Sargassum iliciflium. The seaweed species found to be most abundant in Sargassumiliciflium having 17.8% of the total relative abundance of the species while the seaweed species found to be the least abundant is Laurencia papillosa having only 10.0% of the total relative abundance. The paramaters have all positive correlation coefficient except for the water pH having a negative correlation. There is a substantial relationship or moderate correlation between the frequency of seaweeds with salinity, TDS, DO, and nitrite. There is a small relationship or low correlation between water temperature, conductivity and nitrate and the frequency of seaweeds while there is a slight correlation or almost negligible relationship regarding phosphate and hardness. The diversity of these seaweeds indicates the tolerance of the species to the marine environment.
