Structure of Macrozoobenthos (Gastropods) Community in Mangrove Forest Ecotourism Pandansari Kabupaten Brebes, Central Java

Aims: This research aimed to analyze the abudance and diversity of macrozoobenthos in the Gastropod Class in the Ecotourism Waters of Pandansari Mangrove Forest, Brebes Regency, Central Java.

Study Design: The research was conducted by survey.

Place and Duration of Study: This research was carried out for 3 months between December 2018 until February 2019 in Ecotourism Forest Areas in Bakau Pandansari, Brebes Regency, Central Java.

Methodology: The method used in this research was survey methods using primary data in the form of physical chemistry of aquatic data, gastropod abundance, diversity index, equitability index. Data collection techniques using purposive sampling in determining 3 stations and 3 repetitions. Data analysis in this research used descriptive statistics.

Results: Research results found 9 species of Gastropods inhabiting the mangrove ecosystem, namely Casidulla aurisfelis, Cerithidea sp, Cerithidea alata, Cerithidea cingulata, Cerithidea obtusa, Polinices sp, Puperita sp, Telescopium telescopium and Turiculla nellial-suprius. Gastropod abundance ranged from 67 - 166 ind / m2. Gastropod diversity index in the medium category 2 <H’ ≤ 3. Uniformity values ranged from 0.79 to 0.81 with a high category. The relationship between water quality and gastropods had an R2 value of 97%, water quality can affect gastropod life and as much as 3% is influenced by other factors.

Conclusion: Based on the results of this research that has been done, it can be concluded that in general environmental parameters in the Pandansari mangroves are still favorable in supporting the survival of the gastropods inhabiting them.
