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 Bangka Belitung Islands Province has a mangrove ecosystem covering an area of 273,692.81 hectares. These ecosystems play a crucial role in mitigating greenhouse gas emissions through the sequestration mechanism, which involves absorbing carbon from the atmosphere and storing it in the form of biomass. Human activities around these areas, such as the flow of tailings from artisanal mining (TI), have caused damage to these ecosystems, leading to a reduction in one of the primary carbon dioxides (CO2) absorbers. This study aims to support the sustainable management of mangrove conservation areas in efforts to reduce the impact of global warming. Sampling stations were determined using purposive sampling, with the collection of substrate carbon, biomass, and carbon samples, as well as water quality parameters at Takari Beach. The results showed that the water temperature was 28°C, salinity ranged from 25 to 27 ppt, and pH ranged from 5 to 8,5. Four mangrove species were found at two stations: Rhizophora mucronata, Rhizophora apiculata, Sonneratia alba, and Lumnitzera littorea, totaling 185 trees. The mangrove biomass was measured at 27,10636 tons/ha, and the below-ground carbon stock was recorded at 12,74 tons/ha.
