“…This is also clarified by Simanullang (2018) who explains that a clustered dispersal pattern can occur if ID > 1 is obtained, this clustered dispersal pattern can also occur if individuals tend to be attracted to certain areas of their habitat. According to Kresnasari (2010) in Deni et al, (2020) states that the distribution pattern of fullblooded mussels is related to behavior, reproductive strategies, food availability and environmental conditions. According to Broom, (1985) the reproduction of mussels is hermaphrodite.…”

Geloina expansa is a clam found in mangrove forests. The high level of public consumption and high economic value, is suspected as the cause of overfishing. It is not impossible that continuous harvesting will result in a decrease in the population of G. expansa. The habitat of G. expansa has experienced a lot of land conversion and this will result in a decrease in the natural carrying capacity of its habitat. The purpose of this study was to determine the distribution and density, distribution pattern and size distribution of the population of G. expansa based on the ecology of its habitat in West Malangke waters. The method was carried out randomly, the transect was placed in a 5x5 m2 sample plot with 3 replications and collected directly by hand. Sampling was carried out on each plot at the lowest ebb. Environmental parameters measured in the field included salinity, temperature and substrate while parameters measured in the laboratory were total organic matter (TOM). The density value of G. expansa in the intertidal zone was 9.90 ind/m2 while in the subtidal zone it was 0.78 ind/m2. The distribution pattern found in the intertidal and subtidal zones is clustered. The size distribution of G. expansa in the intertidal zone found that the dominant G. expansa was adult size, and the lowest was in the old size class while in the subtidal zone the dominant size was young and the lowest was in the old size class. Zone and type of substrate affect the existence of G. expansa. G. expansa was found more in the intertidal zone than in the subtidal zone and clay-type of substrates were a determining factor for the presence of full-blooded clams while clay and sand-type substrates were limiting factors for the presence of full-blooded clams.

“…Kondisi tersebut membuat area mangrove memiliki kandungan bahan organik tinggi yang dimanfaatkan sebagai sumber makanan berbagai jenis biota. Selain itu, hutan mangrove secara ekologi berperan penting sebagai spawning dan nursery ground (Rangkuti et al, 2017), serta menyediakan habitat (Kordi, 2012) bagi organisme akuatik, seperti ikan (Faruk et al, 2019;Al Jufaili et al, 2021), kerang (Deni et al, 2020;Wulandari et al, 2022;Safitri et al, 2023), udang (Josia et al, 2019;Faisal et al, 2021), kepiting bakau (Yulianti et al, 2018;Kusuma et al, 2021), termasuk beberapa jenis gastropoda.…”

Gastropods are the largest class of the phylum mollusks, with 75,000 identified species. Gastropods are widely distributed in freshwater, marine waters, and mangrove ecosystems. Gastropods are a fishery commodity with an important economic value containing high protein (36-70.8%) and low fat (0.02-1.50%). This biota has vitamins, essential minerals, omega-3, and omega-6. This research aimed to determine the proximate content (protein, fat, water, ash, and carbohydrates) and macrominerals (Na, K, Mg, Ca, and P) in gastropods found in Bakau Village, Sambas Regency, West Kalimantan. The gastropods found were Ellobium, Cerithidea, and Pirenella. Fifty individuals were taken for proximate analysis. Moisture and ash content were determined by the gravimetric method. Total protein levels were analyzed by the Kjedahl method. The fat content was determined by the Soxhlet method, and the carbohydrate content by the by difference method. Atomic Absorption Spectrophotometer determined mineral macro. The proximate content of mangrove gastropods in Bakau Village is high in protein (48.06–54.62%) and low in fat (1.31–7.40%). The most elevated protein was 54.62 in Ellobium and Pirenella, with the lowest fat being 1.31%. The macro mineral content in gastropods is Ca (14.91-91.48 mg/kg), Mg (13.16-21.74 mg/kg), Na (8.19-20.62 mg/kg), K (13.07-17.33 mg/kg), and P (0.66-0.71 mg/kg). The highest mineral content was shown by the genus Pirenella (91.48 mg/kg) Ca. Keywords: gastropod, macromineral, mangrove, proximate. Abstrak Gastropoda adalah kelas terbesar dari filum moluska dengan 75.000 jenis yang telah teridentifikasi. Gastropoda terdistribusi luas di perairan tawar, perairan laut, dan ekosistem mangrove. Gastropoda merupakan salah satu komoditas perikanan dengan nilai ekonomis penting yang mengandung protein tinggi (36-70,8%) dan lemak yang rendah (0,02-1,50%). Biota ini juga memiliki vitamin, mineral esensial, omega-3 dan omega-6. Penelitian ini bertujuan untuk mengetahui kandungan proksimat (protein, lemak, air, abu, dan karbohidrat) serta makromineral (Na, K, Mg, Ca, dan P) pada gastropoda yang ditemukan di Desa Bakau, Kabupaten Sambas, Kalimantan Barat. Gastropoda yang ditemukan pada penelitian ini adalah Ellobium, Cerithidea, dan Pirenella. Setiap jenis dari gastropoda, masing-masing diambil sebanyak 50 individu untuk dilakukan analisis. Kadar air dan abu ditentukan dengan metode gravimetri. Kadar total protein dianalisis dengan metode Kjedahl. Kadar lemak ditentukan dengan metode soxhlet dan kadar karbohidrat dengan metode by difference. Makro mineral ditentukan dengan Spektrofotometer Serapan Atom. Kandungan proksimat dari jenis gastropoda mangrove Desa Bakau adalah tinggi protein (48,06–54,62%), rendah lemak (1,31–7,40%). Protein tertinggi 54,62 pada Ellobium dan Pirenella dengan lemak terendah 1,31%. Kandungan makro mineral pada gastropoda adalah Ca (14,91-91,48 mg/kg), Mg (13,16-21,74 mg/kg), Na (8,19-20,62 mg/kg), K (13,07-17,33 mg/kg), dan P (0,66-0,71 mg/kg). Kandungan mineral tertinggi ditunjukkan oleh genus Pirenella (91,48 mg/kg) Ca. Kata kunci: gastropoda, makromineral, mangrove, proksimat.

Desa Sungai Nibung, Kubu Raya Regency, has been designated as one of the conservation areas in West Kalimantan. The coastal area of this village has potential of natural resources with a high level of diversity, including bivalves. Local community catch and sell bivalves for consumption. It is due to their high nutritional content, so that they are used by the local community as food and a source of protein. Inventory of biota is the first step to manage biological resources and support the management plan for a conservation area in this village. The study aimed to determine the diversity of bivalves in the coast of Desa Sungai Nibung, West Kalimantan. The research was conducted in December 2022. Sample collection was done using an exploratory method. Bivalves were taken, then stored in the cooling box for further identification. The result showed three bivalve species, such as Polymesoda erosa, Anadara granosa, and A. antiquata.
