Diversity Of Marine Macro Molluscan Gastropods and Bivalves In The Intertidal Areas Of Ajuy, Iloilo, Western Visayas, Philippines

Abstract The Philippines has rich marine resources but are threatened by the effects of climate change and other activities made humans. There is an inadequate or scarcity in literature on prominent impacts country’s biodiversity, specifically ecosystem, thus this study aimed to determine diversity macro molluscan gastropods bivalves intertidal areas Ajuy, Iloilo, Western Visayas, Philippines. Marine were surveyed monthly from October 2015 March 2016 transect method was carried out assess species composition, abundance occurrence. Shannon-Wiener index (H’) utilized area. Coefficient correlation used between physico-chemical properties sea water with value. a total 8,705 individual mollusks sampled classified up 43 having 28 genera belonging 20 families 29 22 14 families. family Muricidae best represented richness among Veneridae bivalves. In wise landing gastropods, maximum number recorded Batillariidae relative 46%. bivalves, most abundant 20.25% abundance. value revealed that area still normal terms diversity. Temperature DO positively correlated H’, whereas pH salinity negatively correlated. This provided baseline information as status
