Abstract

The identification of mangroves thriving around river estuaries is essential for managing natural resource potential in the Selindung Sub-Watershed. This study evaluates the mangrove resource potential and the livelihoods of crab trap fishermen in the Selindung Sub-Watershed, part of the Baturusa Watershed. Conducted from June to November 2024 in Pagarawan Village, Merawang District, Bangka Regency, this research employed a mixed-method approach, integrating qualitative and quantitative analyses, to identify mangrove species and assess the mangrove crab (Scylla spp.) fishery. The results revealed significant natural resource potential in the Selindung Sub-Watershed, encompassing 349 hectares of mangrove forests with dense canopy cover (≥80%), classified as high-quality habitat. Ten mangrove species were identified, including dominant taxa such as Bruguiera gymnorrhiza, Rhizophora mucronata, and Sonneratia alba. The mangrove crab fishery represents a vital livelihood for local fishermen, who supply their catch to Fish Farming Groups (Pokdakan) for fattening purposes. The sustainability of this fishery is closely tied to the health of the mangrove ecosystem. To ensure the long-term preservation of mangroves and their associated resources, sustainable management policies are required, supported by adequate budget allocation, law enforcement, capacity building, equitable supply chain advocacy, stakeholder engagement, and community education. These measures are critical for fostering ecosystem resilience while supporting the socio-economic well-being of local communities.

Abstract

Grouper fish is one _ source of Power ecosystem reef corals that have marked economic highs. The objective Study is to analyze the potency source of grouper fish power in Regency Kolaka. A study was conducted in Regency Kolaka, a coastal area, and eyed fishermen's livelihood as fisherman grouper fishermen. Study This is held for eight months, i.e. April - November 2022. Grouper fish in the waters of Regency Kolaka has experienced excess catch by 70%. Based on these data, effort management needs to be done immediately for the continuity of grouper fish resources in the waters.

Abstract

Seagrass is a higher-level plant that has symbiosis, vessels and reproduces generatively and lives submerged in water. Seagrass has many functions in waters, namely as a breeding ground, primary producer, water stabilizer, and as a sediment trap. The large number of mining activities in the Bangka Belitung Islands Province, especially in South Bangka district, can cause sediment to enter the seagrass ecosystem which will indirectly damage the seagrass ecosystem. Not only mining, many other human activities around the seagrass ecosystem also pose a threat to this ecosystem, such as ship propellers, reclamation activities and dock construction. The method used to determine station points ispurposive sampling, to assess the condition of seagrass using the quadratic transect method at 3 stations, namely Penutuk, Tanjung Sangkar and Tanjung Labu. The research results of the seagrass area on Lepar Island in 2020 was 1437.53 Ha, in 2021 it was 1428.14 Ha, in 2022 it was 1339.54, and in 2023 it was 1258.22. The changes in seagrass area that occurred were a reduction in area of 9.39 Ha from 2020-2021, in 2021-2022 it decreased by 88.6, in 2022-2023 it decreased by 81.22 Ha and the total change in seagrass area from 2020-2023 was reduced by 179.31 Ha. The condition of seagrass cover on Lepar Island is categorized as poor with a percentage of station 1 (Penutuk) 22.042%, station 2 (Tanjung Sangkar) 14.071%, and Station 3 (Tanjung Labu) 0.0868%.

Abstract

Semujur Island, located in Kebintik Village, Pangkalan Baru Subdistrict, Central Bangka Regency, covers an area of approximately 40 hectares and is home to 47 households, the majority of whom are fishermen. The island is known as a center for fishing activities and grouper cultivation and has potential for marine tourism through its diverse coral reefs and reef fish. This study aimed to analyze changes in coral reef area using Sentinel-2A satellite imagery and to assess the influence of sea surface temperature on these changes. Ground truth data were collected in March 2023, consisting of 60 samples classified into four categories: coral reef, dead coral, seagrass, and sand. Image analysis included sunglint correction, water column correction, and supervised classification using the Maximum Likelihood Classifier method. The results indicated a decrease in coral reef area from 104.61 hectares in 2016 to 99.91 hectares in 2023, representing a reduction of approximately 4.5%. Analysis of sea surface temperature data showed an increasing trend, contributing to coral reef degradation. These findings highlight the urgent need for sustainable management efforts to protect the coral reef ecosystem of Semujur Island.

Abstract

Purse seine is a widely used fishing gear in Indonesia for capturing small schooling pelagic species. The study aimed to analyze the catch composition of purse seine fishing performed using the KM Bintang Mas Maritime based at Nusantara Fisheries Port (NFP) Pekalongan and fishing in Indonesia Fisheries Management Area (IFMA 713) Sulawesi Sea. Data was collected through fishing trips observations and catch documentation from September 12, 2023 to February 16, 2024. The total catch was 155,000 kg which was composed of three dominant target species: Decapterus macarellus (32.25%), D. punctatus (29.03%), and Sardinella lemuru (22.59%) which make up 83.87% of the total catch. Bycatch made up 16.13% and included Euthynnus affinis, Rastrelliger kanagurta, Selar crumenophthalmus, and Priacanthus macracanthus. The high proportions of small pelagic fish in the catch is indicative of purse seine selectivity and show the target stocks in IFMA 713 are available. This data highlights the significance of regular evaluation and dynamic management strategies that can adapt to evolving conditions to maintain ecological balance and enduring resources.
