Strategi Pengelolaan Ikan Teri (Stelephorus Sp) di Pelabuhan Perikanan Batu Belubang Kabupaten Bangka Tengah
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.

The Relationship between Mangrove Density and Gastropod Abundance on Tuing Beach, Bangka Regency
This study aims to analyze the relationship between mangrove density and gastropod abundance in Tuing Beach, Bangka Regency. Mangroves have an important role in coastal ecosystems, providing habitat and food sources for a variety of organisms, including gastropods. Gastropods are a group of mollusks that are commonly found in mangrove ecosystems and play a role in the food chain as decomposers. This study was conducted by survey method at three different research stations, where data on mangrove density and gastropod abundance were collected through the square transect method. The study showed that there was a positive relationship between mangrove density and gastropod abundance at all research stations. Station 2 showed the highest mangrove density with a value of 1.733 ind/ha, while the highest abundance of gastropods was also found at Station 2 with a value of 20,3 ind/m². A simple linear regression analysis showed that mangrove density contributed significantly to the variation in gastropod abundance, with the value of the determination coefficient (R²) varying between 0.732 to 0.904 at all three stations. In addition, environmental parameters such as temperature, pH, salinity, and dissolved oxygen are also measured to understand the environmental conditions that affect the distribution of gastropods. The results of this study can provide important information for sustainable management of mangrove ecosystems, especially in maintaining biodiversity and ecosystem stability in Tuing Beach.

Growth Rate Analysis of Mangrove Crab (Scylla Serrata) in Selindung River Fishermen's Catch Apartment
Mangrove crabs (Scylla serrata) and (Scylla tranqueberica) are species that live in mangrove ecosystems. Mangrove ecosystems have a very important role for mangrove crabs, namely as habitat, foraging and spawning grounds. Mangrove crabs can grow and develop in mangrove forests because there are small organisms that become their food. Mangrove crab cultivation is the enlargement of mangrove crabs that are not ready for production using the container method. The container method is the maintenance and enlargement of mangrove crabs using multilevel containers, one of which is to make it easy to control the growth of mangrove crabs this study aims to analyze the growth rate of mangrove crabs (Scylla serrata) in the apartment caught by Selindung River fishermen for eight weeks. Parameters observed included absolute weight growth, absolute carapace width, and water quality such as salinity, temperature, pH, and dissolved oxygen levels. The results showed that the absolute weight growth of male and female crabs was significantly different, with male crabs having an average carapace width of 104 mm and female crabs 54 mm. This growth is influenced by the moulting process, where the crabs replace the old carapace with a new, larger one. The study found that feeding frequency greatly influenced the growth of carapace weight and width. Specific Growth Rate (SGR) of male crabs was highest at 1.14% per day, while females reached 0.75% per day. Male crabs showed a faster growth rate than females, due to higher metabolic activity. Mangrove crab survival rate reached 100%, indicating the apartment method was effective in supporting growth and survival. During the study, water quality remained in optimal condition with salinity of 27-29‰, temperature of 30-33℃, pH 6.1-6.8, and DO 5.5-6.3 mg/L. In conclusion, the apartment system for mangrove crab aquaculture is effective in improving the growth and survival of mangrove crabs in Selindung River.
