Mollusks serve as a vital resource for the coastal communities of South Leitimur, Ambon City, fulfilling their daily needs for sustenance. Traditionally, these communities have relied upon mollusks, including Bivalves and Gastropods, harvested during low tide (bameti), as a primary source of animal protein besides fish. However, the sustained exploitation of these resources, coupled with insufficient awareness regarding resource conservation, poses a significant risk to the continued availability of mollusk populations. Therefore, comprehensive information regarding mollusk distribution is imperative to guide effective fisheries management initiatives.
Research findings reveal that the coastal areas of South Leitimur District, specifically Rutong, Hukurila, and Leahari, harbor a diverse array of mollusk species, totaling 94 distinct taxa spanning 2 classes, 9 orders, 33 families, and 52 genera. Density values across these areas range from 0.003 individuals per square meter to 4.99 individuals per square meter, while frequency of presence values vary from 0.003 to 0.5. Notably, the coastal region of Negeri Rutong exhibits the highest potential abundance of mollusk species, whereas the coastal zone of Negeri Hukurila demonstrates relatively lower potential. Overall, the diversity index indicates a moderate level of species diversity, complemented by a high level of evenness. Additionally, the absence of dominance among specific species is highlighted by the dominance index value. Analysis of distribution patterns reveals that 103 mollusk species exhibit clumped distribution, 40 species demonstrate uniform distribution, and two species exhibit random distribution across the surveyed areas.
