Species Diversity of Marine Bivalves from the Strait of Rupat Island Riau Province, Indonesia

Abstract

A survey of marine bivalves for species diversity was conducted at five locations in the current study; Three stasiun at Dumai city beach those are Silensing, Bandar Bakau, Basilam Baru, Sri Tanjung, and Pulau Payung beach of Rupat Island Strait, Riau Povince. Indonesia. The goal of this study was to learn more about the marine bivalves that live in the Rupat Island strait. From July to August 2020, marine bivalves were collected during spring low tides from intertidal zones and shallow coastal waters. From the Strait of Rupat Island, 13 bivalves belonging to 11 genera, 11 families and 8 orders were discovered. During the research, bivalves from the families Pectinidae, Placunidae, Arcidae, Trapezidae, Veneridae Ostreidae, Corbiculidae, and Psammobiidae were recorded during the study. The number of bivalves in each family reveals that two species belongs to the Arcidae family and two to the Cyrenidae family. Corbiculidae, Placunidae, Trapezidae, and Psammobiidae each had one species reported. The abundance of each species found was extremely low, it is not feasible to be presented quantitatively. The most common species encountered in the strait were Anadara granosa, Polymesoda erosa, Polymesoda expansa, and Pharella acutidens. The anthropogenic activities of Dumai city and Rupat Island, such as the discharge of industrial wastes, residential sewage, overfishing, habitat loss, overharvesting and tourism, could cause variations in bivalves abundance in the Strait of Rupat Island.

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).…”

Diversity of Bivalvia Types in the Mangrove Area of Sungai Nyirih Village, West Kalimantan

“…Bivalvia banyak dijumpai di wilayah pesisir yang masih terkena pengaruh pasang surut (Ambeng et al, 2020). Hasil penelitian sebelumnya melaporkan beberapa jenis yang dijumpai di hutan mangrove, seperti Polymesoda (Deni et al, 2020), Anadara (Tudu et al, 2019), Tegillarca (Meshram dan Mohite, 2016), Geloina (Bahari et al, 2021), dan Meretrix (Nasution et al, 2021).…”
