The coastal vicinity surrounding the Suramadu Bridge serves as a pivotal area catering to transportation, recreation, and conservation purposes. However, the data pertaining to aquatic biota, particularly bivalves, remains relatively understudied. This research, conducted in February 2021, aimed to scrutinize the diversity of bivalves along the Suramadu Coast.
Observations and sampling activities were conducted along three 5 x 5 m transects, each representing distinct habitats. Five bivalve species, namely Mimachlamys sanguinea, Anadara rhomboidalis, Tegillarca granosa, Barbatia trapezina, and Atrina pectinata, belonging to three families (Pectinidae, Arcidae, and Pinnidae), were identified.
The community index results elucidate the individual distribution pattern and community stability, indicating a moderate level of community stability with the presence of a dominant species, Anadara rhomboidalis. However, there were no significant disparities observed in the abundance of individuals, suggesting a state of stress within the bivalve community.
Anadara rhomboidalis emerges as pivotal for community stability, evident through its high Important Value Index and total shell volume. Presently, only two species, Tegillarca granosa and Anadara rhomboidalis, exhibit potential for sustainable utilization.
