“…The gastropod species that were exclusive to the mangrove habitat were members of the family Littorinidae (Littoraria scabra) and family Potamididae (Cerithidea cingulata, Terebralia palustris, Terebralia sulcata and Telescopium telescopium). Similar species were also collected in the mangrove zones of Catanduanes province [9].…”

This study generally aimed to determine the spatial zonation and diversity of bivalves and gastropods in mangrove forest of Cozo, Esteves and Tinib in Casiguran, Aurora. Specifically, this aimed to determine the species composition and distribution, and determine the relationship between spatial zonation and diversity of bivalves and gastropods as influenced by ecological factors such as vegetation, soil texture, organic matter, soil salinity, and soil pH. A total of 22 taxa comprising eight species of bivalves and 14 species of gastropods were identified. The high tidal zone of Esteves had high diversity (0.66) of bivalve species compared to other tidal zones and areas. On the other hand, the diversity of gastropods was almost equal in the middle tidal zones of Cozo (0.60), Esteves (0.57), and Tinib (0.42). In terms of bivalve species' density and abundance, Dendostrea folium was the most dense and abundant in the low tidal zone of Cozo (253,333 ind•ha −1 or 25 ind.m 2-1 , 97.44%) while Gafrarium tumidum in the low tidal zones of Esteves (46,666 ind•ha −1 or 4 ind.m 2-1 , 73.68%) and Tinib (126,666 ind•ha −1 or 12 ind.m 2-1 , 50%). In terms of gastropod species' density and abundance, Cerithidea cingulata was the most dense and abundant in the low tidal zone (666,666 ind•ha −1 or 66 ind.m 2-1 , 65.79%) of Cozo and the middle tidal zone (5,280,000 ind•ha −1 or 528 ind.m 2-1 , 61.40%) of Tinib. It was Terebralia palustris in the low tidal zone (1,263,333 ind•ha −1 or 126 ind.m 2-1 , 63.06%) of Esteves. All tidal zones within each study area had greater dissimilarities in terms of bivalves but had greater similarities in terms of gastropod species' compositions. On the other hand, all tidal zones between study areas had greater dissimilarities in terms of bivalve and gastropod species present. Most tidal zones had Gafrarium tumidum as common bivalve species while Neritidae sp. and Cerithidea cingulata were common gastropod species. All these species were found thriving in a wide range of vegetation, soil texture, organic matter, soil salinity and pH.

“…Meanwhile, it also had a role as filtering water clarity, phytoplankton, and suspended solids on estuary (Gerritsen et al 1994). Mactra also could be found in mangroves and seagrass beds (Masagca et al 2010;Mudjiono et al 1992). Having female and male reproductive organs in separates individual, it is a dioecious animal with free swimming in the larval stage.…”

Roshitafandi DA, Sartika HW, Dewi AK, Nashrurrokhman M, Ratman N, Trijoko. 2018. Short Communication: Seawater Mollusca (bivalve) diversity at Dullah Laut Beach, Tual City, Southeast Moluccas, Indonesia. Ocean Life 2: 21-26. Indonesia is a country that has high-level of biodiversity supported by diverse types of beaches. Dullah Laut Village is located on one of the small islands in Southeast Moluccas. Dullah Laut Beach is a natural white sandy beach with algae, seagrass, and rocky substrate. Bivalve is part of the Mollusca found mostly on the Dullah Laut Beach. The purpose of this research is to know the diversity of Bivalve class in the intertidal zone of Dullah Laut Beach, Southeast Molucca related with the environmental parameters. This research was conducted in July and August 2017. The environmental parameters recorded at the time of the study were 27oC for temperature, 0,01 mg/L for nitrite, and 0,5 mg/L for ammonia. The method used in this study is purposive sampling method. After data collection was completed, the next steps were documentation, preservation, and identification conducted in the Faculty of Biology, Universitas Gadjah Mada, Indonesia. Based on this research, we found 4 genera of the class Bivalve in Dullah Laut Beach namely Atactodea, Macrocallista, Mactra, and Hippopus.

“…This can be compared to previous studies conducted on a few areas, such as the Tubbataha Reef in Palawan, the Kalayaan group of islands, Western Visayas, and parts of Mindanao, which found a significant difference in the species richness of bivalves and gastropods. Briefly, Masagca et al [10] discovered 27 species of gastropods and 30 species of bivalves. There were 89 gastropods and 19 bivalve species recorded in Binunsalian and Turtle Bays, Palawan [11], 50 gastropods and 15 bivalves recorded in Iwahig River-Estuary-Palawan [12], and 69 gastropods and nine bivalves recorded from Kalayaan Islands [9].…”

“…Most studies on mollusc species in the Philippines were based on the collections of mollusc species by many foreign researchers, such as Hugh Cummings' collections from 1836 to 1840 [9]. There have been a few studies focusing on the locality of marine macro molluscs, such as the studies conducted on Catanduanes Island by Masagca et al [10], in Binunsalian and Turtle Bays by Picardal and Dolorossa [11], in Iwahig River-Estuary by Dolorossa and Dangan-galon [12], in Tubbataha Reefs Natural Marine Park conducted by Dolorossa et al [13], and in Palawan, and Kalayaan Island Group (KIG) conducted by Batomalaque et al [9]. In addition to these, there are also a few studies conducted in part of Mindanao, such as the survey conducted in Hadji Panglima Tahil, Province of Sulu [14], in Alabel and Maasim, Sarangani Province [15], and in Padada, Davao del Sur [16].…”

There have been very few studies on mollusk diversity in remote areas of the Philippines. The coastal areas of Caramoan, Camarines Sur, are ideal for studying marine molluscs because they have been discovered to be abundant, diverse, and essential to the locals’ livelihood. However, due to the remoteness of the mentioned area, this lack of information remains scientifically lacking. Thus, this study aimed to determine the diversity of marine macro-molluscan bivalves and gastropods in the intertidal areas of Barangay Paniman, Caramoan, Camarines Sur, Philippines. Purposive sampling and transect methods assessed the species composition, abundance, and occurrence of marine macro bivalves and gastropods. The Shannon-Wiener index was used to determine the area’s diversity. A total of 557 individual molluscs were sampled and classified, obtaining 43 species of bivalves from 32 genera and 18 families and 47 species of gastropods from 34 genera and 20 families. The family Veneridae had the highest among the bivalves, and the family Strombidae had the highest species richness among the gastropods. This study provided baseline information on the status of marine macro molluscan bivalves and gastropods in the intertidal area of Barangay Paniman, Caramoan, Camarines Sur, Philippines. As a result, this will provide solid empirical evidence for conservation and sustainability plans.
