Abstract
Marine algae and gastropods occupy the intertidal zones and play a significant role in the tidal ecosystems. Algae and gastropods have many uses like therapeutics, food industry, preparation of tools and many more. Konkan coastal line covers an area of approximately 720 km. among this coastline Anjarle coast covers approximately 6.9 km. Anjarle beach, Savne beach, Padale beach and Aade beach have different levels of human activities which allows the appearance of various varieties of algae and gastropods. Total of 11 species of algae from nine families were identified. 23 species of gastropods belonging to 13 different families were identified from the selected study sites. The data were collected from Jan 2024 to Aug 2024. Eleven species from nine genera and eight families made up the algal community, whereas twenty-three species from eighteen genera and thirteen families made up the gastropod population. Ulvaceae and Dictyotaceae dominated among algae, whereas Neritidae dominated among gastropods, according to percentage composition. Gastropods have greater species richness and diversity (H2 = 3.14) than algae (H2 = 2.40), according to diversity indices. High evenness was shown by both groups, indicating a comparatively consistent distribution of species across taxa. The data deal with preliminary analysis of diversity of algae and gastropods along the Anjarle coast, Maharashtra, India.
