Biodiversity of bivalves in the mangrove ecosystem in Kampung Jawa, Banda Aceh

Abstract

Mangrove ecosystem as a feeding ground contributes to habitat complexity and diversity of the macrofauna, while bivalves are dominant in this ecosystem. The diversity of Bivalve had influenced by habitat conditions that have an impact on ecosystem stability. This research purposed to assess diversity and species abundance of bivalve in Kampung Jawa. The parameters analyzing included density, diversity index, and the species of a dominant index. The research was conducted in March 2020 at five stations with purposive sampling method. There are 8 species of Bivalve found in this area. The Bivalve species found are Nucula sulcata, Anadara granos, Glycymeris Modesta, Anadara transversa, Brachidontes granulatus, Anadara nodifera, Cucullaea Labiatae, and Glycymeris glycymeris. The analysis showed that Anadara transverse species was the most abundant with a density value 5.2 ind/m2. Diversity values from the five stations have obtained at 0.69 - 1.37 with a medium diversity category indicated that the variation of Bivalve species is quite diverse.

Morphometric composition analysis of Sinanodonta woodiana based on depth stratification in Tributaries Meureubo West Aceh

“…Sinanodonta woodiana atau Anodonta woodiana (Gabka et al, 2007) merupakan salah jenis kerang dari filum moluska kelas bibalvia, (Heriansyah et al, 2020;Hermi, 2020;Mursawal et al, 2022). Kerang ini termasuk dalam biota benthos atau hewan yang hidup pada dasar perairan (Hermi et al, 2021;Ramadhaniaty et al, 2021;Sarong et al, 2022) .…”

Inventory of Bivalve in the Coastal Area of Desa Sungai Nibung West Kalimantan

“…Bivalvia dapat ditemukan di daerah pasang surut (Asadi et al, 2018;Ambeng et al, 2020), berasosiasi dengan terumbu karang (Ali et al, 2017), padang lamun (Syukur et al, 2021;Donaher et al, 2021;Basmalah et al, 2022), dan ekosistem mangrove (Sarong et al, 2019;Putri et al, 2021;Rinaldi et al, 2021). Jenis yang dapat ditemukan, seperti Anadara, Polymesoda, Meretrix (Nasution et al, 2021;Ramadhaniaty et al, 2021), Geloina (Sarong et al, 2019), Pharella, Paphia (Suryono et al, 2017).…”

Macrozoobenthos diversity and heavy metal contamination in Faunus ater in the Rasian and Asahan rivers in the southern coast of Aceh, Indonesia

“…Macrozoobenthos are demersal organisms that are sedentary and have slow movements, making them highly susceptible to environmental conditions (Minggawati, 2013). Due to this sensitivity, macrozoobenthos are frequently used as bioindicators for assessing water quality (Dabrowska et al, 2016;Rosdatina et al, 2019;Ramadhaniaty et al, 2021). These species play an important role in the aquatic ecosystems as decomposers (Desmawati et al, 2020;Kumar et al, 2013) and transfer energy to the next trophic levels as prey for other aquatic animals such as fish and water birds (Ridwan et al, 2016;Jędruch et al, 2019).…”
