Diversity, Abudance and Potential Mollusc in Intertidal Zone Pandawa Beach Kutuh Village Badung Bali

Diversity, Abundance and Potential of Molluscs in the Intertidal Zone of Pendawa Beach, Kutuh Badung Village, Bali

The intertidal zone of Pendawa Kutuh Bali beach is a very attractive tourist attraction both domestically and abroad because of the white sand, vast expanse of coughs can be seen if the lowest ebb and cano games are fun for tourists. The existence of one of the marine biota resources namely mollusks can be used as a tourist attraction in the fields of education, economics and conservation as well as towards environmentally friendly tourism. The diversity, abundance and potential of mollusks are needed research to support the development and environmental preservation of the Pendawa coastal waters as a tourist attraction. Mollusk samples were taken using a purposive sampling method of four transect lines to the vertex towards the sea with a 1X1 meter squared of 15 squares per transect. The distance between the squares of each transect is 10 m and 500 m between transects. the sampling time was carried out for 3 months at the lowest ebb time with in-situ observations and ek-situ which included identification and quantitative analysis. based on the shanon-Wiener index and abundance referring to Krebs conducted in the Ecology and Taxonomy Laboratory of Biology Study Program FMIPA UNUD. Identification results were found 6 types of mollusks, conus frigidus types spread evenly and Chiton sp has a niche in a narrow area ie on transects 1. quantitative analysis 3 times observations resulted in a diversity index at a moderate level at the bottom line between 1,080-1,673, except for transect 1 in April, which was 0.876. There is no uniformity and dominance index indicating the existence of a dominant type and the uniform uniformity of the number of individuals. The abundance of molluscs in all transects at a low level is 0.06-0.80 ind./m2, except transects 1 in April (1.40 ind / m2) and May (1.33 ind / m2. Chiton and Turboargyrostoma species have potential as an economically valuable source of protein to be developed and preserved.
