Abstract

Taxonomically, according to the World Register of Marine Species (WORMS), in 2021 the naming of the species Cymodocea serrulata will change to Oceana serrulata (R. Brown) Byng & Christenh. Many studies have been carried out in the Province of the Bangka Belitung Islands, but this type of distribution map has not been presented in detail. Observation of seagrass in the field allows the identification of seagrasses with other types of seagrass. This study aimed to identify morphology, species distribution, and other types of seagrass often associated with seagrass species Oceana serrulata in the Province of the Bangka Belitung Islands. The methods in this study include data collection, identification, and map making. Morphological identification of seagrass species refers to several identification sources. The distribution map of Oceana serrulata is presented from the seagrass data collection that has been carried out. This research uses data from different times, the first was obtained from 2011 and 2022 as primary data. The results of the study explain the identification carried out on the Oceana serrulata has the same characteristics as identification literature. Similarities seen from the identification of leaf morphology which ribbon curved like, parallel leaf veins and triangular shaped sheaths. Other seagrass species that are most often associated with Oceana serrulata are Halodule uninervis and Enhalus acoroides. The map of the distribution of seagrass species Oceana serrulata is found on the islands of Bangka, Belitung, Anak Air, Lepar, Ketawai, Semujur, Kalimambang, Kelayang, Kepayang, Ruk, and Sebongkok islands.

Abstract

Mangrove ecosystems are similar to other forest ecosystems in that they play a role in absorbing CO2 from the atmosphere. Mangrove ecosystems can store more carbon compared to most rainforests. This is because mangrove plants utilize CO2 for photosynthesis and store it in the form of biomass and sediments. The purpose of this research is to determine the potential of mangrove ecosystems in absorbing and storing carbon, particularly the content of below-ground carbon and Biomass from several locations on Lepar Island. The data collection method used systematic sampling, where the placement of sampling plots had regular distances from the sea to the land. Substrate samples were taken using a core sampler tool and analyzed using the Loss of Ignition (LOI) method to determine carbon content. The research results showed that the average soil density at all stations was 1.0 g/cm3. The average percentage of organic carbon at all stations was 0.09 C%. The average total carbon content at all stations was 105.73 tons/ha. Mangrove forests are capable of storing a large amount of carbon in both biomass and sediments.

Abstract

South Bangka Regency is one of the districts that has the potential for fish biodiversity in seagrass meadows when viewed from its area and diversity.  Seagrass beds are areas that have the potential to be conservation sites from an ecological point of view and represent the sustainability of fish resources. This study aims to determine the richness of fish species, fish composition, abundance, diversity, uniformity and dominating fish as well as the relationship of seagrass cover to the abundance and biomass of fish found in southern Bangka Waters.  The study will be conducted in southern Bangka Regency in June 2023 covering 4 stations. Seagrass data collection in the form of seagrass cover using the quadratic transect method and swept area method (sweep) in fish data collection. The results of the study from the four stations there were 243 individuals including 23 species of fish from 18 families namely Alosidae, Apogonidae, Chaetodontidae, Engraulidae, Gerreidae, Labridae, Lethrinidae, Pinguipedidae, Platycephalidae, Scorpaenidae, Siganidae, Sphyraenidae, Syngnathidae, Terapontidae, Ambassidae, Gobiidae, Monacanthidae and Leiognathidae. The highest fish species composition was found at station 4, namely Gerres limbatus by 32.51% with 79 individuals. The abundance value found was 822 ind/ha and fish diversity was categorized as medium, fish uniformity tended to be high and dominance index was low. The abundance and biomass of fish are influenced by the percentage of seagrass cover, where the higher the percentage value of seagrass cover, the higher the abundance value and biomass of fish in the area. Kabupaten Bangka Selatan merupakan salah satu kabupaten yang memiliki potensi biodiversitas ikan di padang lamun jika dilihat dari luasan dan keanekaragamannya.  Padang lamun adalah kawasan yang berpotensi sebagai tempat konservasi dilihat dari sudut pandang ekologis dan mewakili keberlanjutan sumber daya ikan. Penelitian ini bertujuan untuk mengetahui kekayaan jenis ikan, komposisi ikan, kelimpahan, keanekaragaman, keseragaman dan ikan yang mendominasi serta hubungan tutupan lamun terhadap kelimpahan dan biomassa ikan yang ditemukan di Perairan Bangka bagian selatan.  Penelitian dilakukan di Kabupaten Bangka bagian selatan pada bulan Juni 2023 meliputi 4 stasiun. Pengambilan data lamun berupa tutupan lamun menggunakan metode transek kuadrat dan metode swept area (sapuan) pada pengambilan data ikan. Hasil penelitian dari keempat stasiun terdapat 243 individu mencakup 23 spesies ikan dari 18 famili yaitu Alosidae, Apogonidae, Chaetodontidae, Engraulidae, Gerreidae, Labridae, Lethrinidae, Pinguipedidae, Platycephalidae, Scorpaenidae, Siganidae, Sphyraenidae, Syngnathidae, Terapontidae, Ambassidae, Gobiidae, Monacanthidae dan Leiognathidae. Komposisi jenis ikan tertinggi terdapat pada stasiun 4 yaitu Gerres limbatus sebesar 32,51% dengan jumlah individu 79. Nilai kelimpahan yang ditemukan adalah 822 ind/ha dan keanekaragaman ikan dikategorikan sedang, keseragaman ikan cenderung tinggi dan indeks dominansi tergolong rendah. Adapun kelimpahan dan biomassa ikan dipengaruhi oleh persentase tutupan lamun, dimana semakin tinggi nilai persentase tutupan lamun maka semakin tinggi juga nilai kelimpahan dan biomassa ikan di area tersebut.

Abstract

Perairan Tukak memiliki keanekaragaman hayati yang tinggi, termasuk populasi hiu yang terancam akibat aktivitas antropogenik yang intensif. Penelitian ini bertujuan untuk mengidentifikasi karakteristik morfometrik dan meristik hiu yang tertangkap dengan jaring insang serta menganalisis status konservasinya. Penelitian ini dilakukan pada Juli 2024 di Dermaga Tukak, Kabupaten Bangka Selatan. Pengumpulan data mencakup panjang total (TL), panjang prekaudal (SL), panjang cagak (FL), dan berat. Selanjutnya, dilakukan identifikasi spesies hiu yang ditemukan di perairan Tukak, Bangka Selatan, dan dibandingkan dengan daftar IUCN serta CITES untuk menilai tingkat ancaman dan regulasi perdagangan. Hasil penelitian menunjukkan bahwa semua individu Atelomycterus marmoratus yang tertangkap berjenis kelamin betina (40–43 cm TL), sedangkan dua individu Chiloscyllium punctatum jantan berukuran 40–42 cm TL. Kedua spesies ini belum mencapai kematangan seksual, yang mengindikasikan eksploitasi sebelum usia reproduksi. Spesies ini dikategorikan sebagai Near Threatened oleh IUCN. Hasil penelitian ini mendukung kebijakan konservasi dan perlindungan habitat hiu. Edukasi kepada nelayan mengenai pengurangan tangkapan sampingan (bycatch) dan pelepasan hiu perlu ditingkatkan. Keterbatasan penelitian mencakup jumlah sampel yang terbatas dan cakupan geografis yang sempit. Jika identifikasi visual tidak memungkinkan, metode DNA barcoding dapat digunakan untuk memastikan identifikasi spesies hiu secara akurat di perairan Tukak, Bangka Selatan.

Abstract

Coral reefs play an important role as marine habitat, but are threatened by climate change and human activities. The Tuing Marine Conservation Area, which still has a relatively good coral reef ecosystem, needs to be evaluated to ensure the effectiveness of conservation and support sustainable management. This research evaluates the condition of coral reefs, coral fish biomass and the relationship between coral reefs and coral reef fish in the Tuing Marine Conservation Area located in Tuing Hamlet, Mapur Village, Bangka Regency. Data collection was carried out in March 2024 at three coral reef locations using the underwater photo transect method to observe the percentage of coral cover and the visual census and visual census methods to observe coral reef fish. The average live coral cover is 60.21%, included in the good category. The density of coral fish is 4,905 individuals per hectare with a total of 10 – 14 species. Reef fish biomass is 65.51 kg per hectare. The relationship between coral reefs and coral fish shows that the better the condition of the coral reef, the higher the number of species and biomass of coral fish. These findings highlight the importance of preserving coral reef ecosystems to support biodiversity and sustain fisheries. Conservation efforts should focus on reducing anthropogenic activities, increasing public awareness, and implementing effective management and rehabilitation strategies

Abstract

This study aimed to analyze the community structure of reef fish in the small island waters of Central Bangka. The research was conducted in March 2022 in the waters of Bebuar Island, Ketugar Island, Ketawai Island, and Gusung Asam Central Bangka Regency, Bangka Belitung Islands Province. The coral reef survey method uses purposive sampling and the coral reef fish visual census with data analysis of abundance, diversity index, uniformity, and dominance. In-site water quality measurements included six parameters: temperature, salinity, current, brightness, depth, and pH. The results showed that coral reef cover from 44.60 - 87.00% with the medium to very good category. The abundance of reef fish from 1 to 3 individuals/m2 was dominated by 18 species of the Pomacentridae family. The reef fish diversity index ranged from 2.47 to 2.90, including the medium category. The uniformity index value ranged from 0.79 - 0.94, including the high category, indicating that the species found were evenly distributed across all stations. The dominance index value ranges from 0.07 to 0.15, including low, where no species dominates significantly and the fish are evenly distributed. Temperature, brightness, pH, and salinity are factors that support the growth of coral and reef fish. A water current speed of 0.05 – 0.20 m/s is quite helpful in cleaning coral reefs from mud and can supply oxygen. Water conditions were categorized as good and fulfilled the seawater quality standards.

Abstract

The Baronang fish (Siganus guttatus) is an economically valuable species commonly found in seagrass ecosystems, which serve as critical habitats providing food, spawning, and nursery grounds. This study, conducted from June to August 2024, aimed to examine the length-weight relationship, growth patterns, and the influence of environmental parameters on Baronang fish growth. Fish samples were collected using beach seines of various mesh sizes. The length-weight relationship in June followed the model W = 0.12L².19 (R² = 0.72), in July W = 1.07L⁰.34 (R² = 0.99), and in August W = 2.72L⁰.674 (R² = 0.94), indicating varying degrees of correlation across months. Growth analysis using the von Bertalanffy model showed an asymptotic length (L∞) of 154.00 mm and a growth coefficient (K) of 0.51/year. In August, the estimated L∞ was 19.95 cm, K = 1.01/year, and t₀ = 0.176. The fish reached a length of 88.97 mm in the first year and 150.95 mm by the sixth year, with growth slowing down after this period. Environmental parameter analysis revealed that temperature had a significant positive effect on fish weight (B = 14.664, p < 0.001), while salinity (B = -5.920, p = 0.005) and dissolved oxygen (DO) (B = -28.357, p = 0.001) had significant negative effects. These findings highlight the importance of environmental conditions in regulating the growth of Siganus guttatus in seagrass ecosystems.

Abstract

Land clearing for mining operations can potentially cause severe damage to coastal and marine environments. Restoration of post-mining areas can be addressed through closure and recovery efforts, particularly via coral reef rehabilitation. This study aims to determine site suitability for coral reef rehabilitation or marine reclamation in the waters of Tanjung Siangau. Conducted in August 2023, the study used a multi-parameter map overlay method to produce a suitability map for reef rehabilitation. Parameters considered include bathymetry, turbidity, current velocity, wave conditions, substrate type, reef exposure, protection status, proximity to coral donor sources, community involvement, and marine spatial zoning. Findings indicate that areas damaged by coastal and marine activities require reclamation, including coral rehabilitation. Reclamation of post-mining lands must adhere to Indonesian Law No. 3 of 2020 and the Mineral and Energy Resource Ministerial Regulation No. 26 of 2018. Overlay results revealed the highest suitability score in the southern waters of Tanjung Siangau, an area categorized as moderately damaged coral cover (<50%). Local community reports indicate that this area is not mined due to the absence of tin deposits. The recommended site for coral reef rehabilitation lies outside of any licensed mining concession and is situated within an Underwater Tourism Zone in accordance with the Coastal and Small Islands Zoning Plan (RZWP3K).
