Abstract

Tanjung Labu waters have a coral reef ecosystem and are rich in a variety of biota such as the Pomacentridae and Chaetodotidae families. This family is an indicator of the health of coral reefs and plays a role in maintaining ecosystem balance. The aim of the research is to calculate the abundance of the Chaetodontidae and Pomacentridae families and analyze the relationship between the abundance of Chaetodontidae and Pomacentridae fish and habitat characteristics in coral reef ecosystems. The research was carried out in March 2024 in the waters of Tanjung Labu. The method used is UPT (Underwater Photo Transect) for coral reefs and UVC (Underwater Visual Census) for coral reef fish and the PAST 4.03 application to determine the relationship. The research results showed that the average live coral cover was 51.15%, and the abundance of the Chaetodontidae and Pomacentridae families was 1/m2. The number of individuals and species of the Chaetodontidae family is 37 individuals and 3 species, while the Pomacentridae family is 386 individuals and 20 species. The Chaetodontiadae family relationship is positively correlated with basic substrate cover components such as abiotic and other fauna, as well as environmental parameters such as brightness and current speed, but is negatively correlated with live coral and the type of coral reef life form, while the Pomacentridae family relationship is positively correlated with the closure component. basic substrates such as coral reef life form and dead coral, as well as environmental parameters such as water depth.

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.

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.

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

The marine and fisheries sector plays a vital role in national development, particularly as a major source of employment across various stages, from fishing and aquaculture to processing, distribution, and marketing of fishery products. As such, this sector requires focused governmental attention across the entire value chain, from upstream to downstream. In Batu Belubang Village, Bangka Regency, the local fishing catch is dominated by anchovies (Stolephorus sp.). According to a report from Babel Today (September 28, 2024), this abundance raises a critical question: is it a blessing or a burden for local fishermen? To support the sustainable development of the anchovy value chain and align production with consumer demand, this study seeks to formulate a strategic management approach for anchovy resources at the Batu Belubang Fishing Port. Fieldwork was conducted in October 2024. The study employed qualitative methods, gathering primary data through interviews with fishing vessel owners, small-scale fish processors, and the head of the Batu Belubang Fishing Port. Secondary data were obtained through literature reviews, including scholarly journals, books, online resources, and mass media coverage. A SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis was applied to assess resource potential and identify development constraints. The study concludes that enhancing the anchovy-based fisheries sector requires an integrated approach that includes: promoting the national “Love Eating Fish” campaign (GEMARIKAN) with a specific focus on anchovy products; providing technical training and support for local fish processing with appropriate technological innovation; extending the Batu Belubang port pier to improve infrastructure; and revising fishing quota policies to support sustainability and market efficiency.

Abstract

The coral reef ecosystem is one of the ecosystems that functions as an important habitat for various marine species including coral reef fish, provides coastal protection, and supports economic activities such as fisheries and tourism. The study was conducted in March 2024 in the waters of Tanjung Labu, Bangka Selatan, precisely in Karang Kucek and Karang Tepi, with a total of 8 stations. This study aimed to determine the coral reef health index, diversity index, uniformity and dominance of coral reef fish, and the relationship between coral reefs and coral reef fish. The method of collecting coral reef data uses UPT (Underwater Photo Transect) and coral reef fish using UVC (Underwater Visual Census). The results of the study showed that the coral reef cover value in Tanjung Labu waters was classified as good with an average value of 51.14%, and coral fragments and fleshy seaweed algae were relatively low. The average coral reef health index value was 5.75, in the good range of 4-6 with high coral cover and good recovery potential. The community structure showed a low dominance index, moderate diversity, and uniformity indicating a labile community. Analysis of the relationship between coral reefs and coral reef fish shows a significant relationship, with a high correlation between the number of coral reef life form species and the number of individuals and biomass of coral reef fish. Public education and ongoing research are also important, with collaborative support from the government, organizations, and local communities for successful conservation.

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.
