The mangrove area in the coastal area of Karawang Regency has become an area that is ecologically pressured by the surrounding area, which greatly affects its sustainability. Coastal community awareness is very important to preserve the mangrove areas. This study was conducted from October 2016 to March 2017. At nine coastal districts of Karawang Regency, it aims to analyze fisheries’ productivity associated within mangroves ecosystem based on mangrove data produced in 1995, 2005 and 2015. Correlation analysis between the production of some fishery commodities and mangrove area was conducted using SPSS 17. The results showed that the correlation between the mangrove ecosystem and the capture fisheries production was 0.7257. It can be concluded that there was a relationship between the mangrove ecosystem and the total fisheries production in Karawang Regency. The condition was expressed by the production of speckled shrimp, white shrimp, mullet and crab.
Abstrak One of the main coastal ecosystems of Tangerang Regency is the mangrove ecosystem is the mangrove ecosystem has numerous functions. However, this does not guarantee that it would not experience degradation and damage. Therefore, this study aims to analyse the level of mangrove ecosystem degradation in Tangerang Regency. The method used in this study is purposive sampling, whilst the measurement was performed through transect and non-transect methods with a reference to Indonesian National Standard Number 7717 year 2011. Data analysis in this study refers to calculations based on the Decree of the State Minister of Environment Number 201 year 2004 and Fauzi and Anna’s study in 2005. Results of this study indicated that the level of mangrove density of all village sites/stations in the category of rarely-damaged due to the fact that density values in all villages are below the range of 1,000 trees/ha. Meanwhile, the percentage value of mangrove cover is under the category of rarely-damaged to tightly-good. Even so, observation areas in Tangerang Regency are dominated by mangrove conditions in a rarely-damaged category. According to the analysis of the calculation of degradation level indicated mangrove ecosystem in Tangerang give trend in degradation categories.
This study assessed variations in the relationship between zooxanthellae and their coral hosts seasonally and spatially. Carbon and nitrogen stable isotopes (d13C and d15N) were used to analyze the patterns of nutritional transport between coral and zooxanthellae. Studies of temporal differences were conducted during two dry seasons and one rainy season in the Berau Marine Conservation Area, East Kalimantan, Indonesia. To assess spatial variations, coral samples from three genera (Porites, Seriatopora and Stylophora) were collected from three localities, designated as nearest, medium, and farthest from the Berau River mouth. The lower d13C of Seriatopora compared with the other two genera suggested that corals in this genus were more actively utilizing particulate organic matter and adopting a heterotrophic feeding mode. The d13C values of coral tissue and zooxanthellae also were affected by differences in seasons, localities, and depth, whereas the d15N values varied significantly with seasons alone. Differences in d15N values between coral tissue and zooxanthellae were always positive in the first and second dry seasons, but negative in the rainy season. This finding indicated that zooxanthellae were the main source of coral nutrients during the dry season, while host coral may support zooxanthellae nutrition during rainy season of low turbidity. Spatially, sedimentation does not show significant impact to the relationship between coral and zooxanthellae

The Arafura and Timor Seas region is shared by Indonesia, Timor Leste, Australia, and Papua New Guinea (PNG), and is at the intersection of the Pacific and Indian oceans. High coastal population densities, degraded habitats, overexploited fisheries, low profile coasts, shallow continental shelves and macro-tidal conditions mean that coastal and marine environments in the region are currently facing multiple pressures. Climate change is expected to exacerbate these pressures and have profound effects on the status and distribution of coastal and marine habitats, the fish and invertebrates they support and, therefore, dependent communities and industries. Downscaled climate change projections for 2041–2070 for air and sea temperature, ocean chemistry and rainfall were modelled to provide spatially relevant regional data for a structured semi-quantitative vulnerability assessment. Results of the assessment were spatially variable and identified shallow coral reefs as highly vulnerable, particularly in the Timor-Leste and Indonesia-Arafura sub-regions. Seagrass meadows were most vulnerable in the Gulf of Carpentaria, Indonesia-Arafura, and Timor-Leste sub-regions. Mangrove habitats were most vulnerable in Timor-Leste and Western PNG sub-regions. Drivers of vulnerability include poor habitat condition, non-climate pressures, low connectivity, and limited formal management. Marine species vulnerability was also spatially variable, with highly vulnerable and priority species identified for each sub-region, including finfish and marine invertebrates. A key driver of species vulnerability was their stock status, with many species in Timor-Leste, Western PNG and Indonesia, and several in northern Australia, overfished or potentially overfished. Limited management in some sub-regions, as well as non-climate pressures such as habitat decline, poor water quality and illegal, unregulated and unreported fishing were also key drivers. Species of conservation interest (dugong and marine turtles) were also highly vulnerable to climate change, driven by their threatened status and the fact that they are low productivity species that take years to recover from impacts. Priority species and habitats for local action were identified and current pressures that undermine condition and/or resilience, with strategic recommendations aimed at minimising climate change vulnerability.
