Marine ornamental trade is multi million dollar industry, worth an estimated US$200 to 350 million annually, and operating throughout the tropics [1].
Marine ornamentals are, in fact, one of the highest value-added product from coral reefs, with an estimated worth of US$ 7,000 per metric ton of live coral, while harvested coral for lime only worth US$60, and fish for food only worth US$6,000 compared with US$496,000 for ornamental fish per metric ton [2].
Indonesia and the Phillipines are the world’s leading exporters of marine ornamental fish, supplying an estimated 85% of fish imported by the United States and Europe, the trade’s largest consumers [3,4].
Most of these fishes are collected from the wild, primarily from on or near coral reefs, therefore causing population depletion [5].
In the past, the trade may seem uncontrollable, since few species are listed in CITES Appendix or IUCN Redlist. CITES only listed corals, napoleon wrasse, giant clams, and sea horses on their appendix [6].
In 2008, IUCN Redlist added 837 coral species to the list [7].
The main concern for this trade is the probability of rejected catch which is very high [1], thus increasing threat to the ecosystem [8].
Therefore there is a need to make the trade become more effective, efficient and environmental friendly.

Sangiang Island had been established as a Nature Recreation Park (TWA) in Indonesia, that requires comprehensive data support for good management. The rise of marine tourism that increased in TWA Sangiang Island behoove to be a concern, especially in coral reef ecosystem. The study aimed to determined the condition of the coral cover and the biomass composition of coral reef fishes, then to identify parameters that affect coral health and the coral reefs health index in TWA Sangiang Island. The observation was carried out in area near to the estuary (Legon Waru), entry point for shipping (Tembuyung), and diving tourism (Legon Bajo). The highest of biomass of target fish was Legon Bajo (0.013 kg / ha) and the lowest was Tembuyung (0.002 kg / ha). Coral reefs health index values in each station varied from 1 (low) to 4 (high). Coral reefs health index in Legon Waru was strongly influenced by live coral cover, and also in Legon Bajo was influenced by live coral cover, rubble and biomass of target fishes, while in Tembuyung was much influenced by fleshy seaweed cover. The results indicated that the coral reef ecosystem on Sangiang Island wasn't in good condition as a whole.

GENERATING BIOLOGICALLY RELEVANT ENVIRONMENTAL DATA FROM REMOTE SENSING IMAGE...Yayasan TERANGI
Long term Earth observation data stored in Google Earth Engine (GEE) can be ingested and derived to biologically relevant environmental variables that can used as the predictors of a species niche. The aim of this research was to create a script using GEE to generate biologically meaningful environmental variables from various Earth observation data and models in Indonesia. Elevation and bathymetry raster data from GEBCO were land masked and benthic terrain modelling were done in order to get the aspect, depth, curvature, and slope. HYCOM and MODIS AQUA dataset were filtered using spatial (Indonesia and surrounding region) and temporal filter (from 2002–2017), and reduced to biologically meaningful variables, the maximum, minimum, and mean. Water speed vector (northward and eastward) data were also converted in to scalar unit. In order to fill data gaps, kriging was done using Bayesian slope. Results shows the water depth in Indonesia ranges from 0 – 6827 m, with slope ranging from 0 – 34.33°, aspect from 0 – 359.99°, and curvature from 0 – 0.94. Variables representing water energy, mean sea surface elevation ranges from 0 – 0.85 m, and mean scalar water velocity 0 – 4 m/s. Mean surface salinity ranges from 20.09 – 35.32‰. Variables representing water quality includes mean of particulate organic carbon which ranges from 25.31 – 953.47‰ and mean of clorophyll-A concentration from 0.05 – 13.63‰. These data can be used as the input for species distribution models or spatially explicit decision support systems such as Marxan for spatial planning and zonation in Marine and Coastal Zone Management Plan.
