Production of commercial fish (various species) = 120 ton/month; Black coral fish Badar = 50 ton/month; Lola = 10 ton/month; Sea slug = 5 ton/month; Shellfish = 5 ton/month; Octopus = 2 ton/month (1989)

Consists of 99 large and small islands. Small islands had sandy shoreline, while large islands had sandy shoreline, mangrove forest and rocky cliffs of height 3 – 20 m above sea- level. Elevation ranged 0 – 15o. Sea areas

with mangrove forest stands had mud substrate, partly stony and sandy, while areas bordering sandy shores generally had sandy substrate and coral in some places (Porites

sp.). Coral reef was on flats that were not very wide and was still in fairly good condition. Coral species generally found were hard corals: stone corals (Porites lutea, Porites

cylindrical dan Porites sp.), needle corals

(Seriatopora hystrix, Acropora aspera, A.

palifera, A. nobilis dan Acropora sp.), brain

coral (Lobophyllia sp.), foliose coral

(Montipora foliosa), fire coral (Millepora sp.),

sea fans (Subergorgia sp.). Soft corals were: black coral (Antiphates spp.), Gorgonia spp., and sponges. Coral reef formation was barrier reef.

Physical structure of coral reef: 90%

damaged and broken at depths of 2-3 m, coral type still existing is massive coral. 3/4 of the Acropora digitata and tabulate was damaged. Living coral cover: 10% at depths of 2-3 m. At depths greater than 3 m coral cover was still in good condition.

Sedimentationi (mud, sand or pebbles) was not detected during the survey,

sedimentation may have occurred for several days after the tsunami (2005)

IPB (Coral reef condition in the waters of Pulau Weh, Aceh. Thesis, Dept. of Marine Science & Technology, Faculty of Fisheries and Marine Science, Bogor Agricultural University)

Area west of Pulau Weh, percentage of

stone coral cover ranged from good to moderate (north of Teluk Lheung Angin = 28.17 %.Teluk Dalam Lheung Angin = 9.93 %); mortality index (north of Teluk Lheung Angin = 0.62, Teluk Dalam Lheung Angin = 0.58), Substrate generally sandy and stony. Coral life forms were dominated by

Acropora, the most commonly found was

branching Acropora.

Area north of Pulau Weh, coral cover showed range from bad to good. Lifeform composition dominated by Acropora. Mortality Index varied from 0.05 to 0.64, influenced by rubble cover.

Area east of Pulau Weh, Percentage of coral cover was moderate to very good, because influence from human activity was low (2004)

(depth 3 m) The eastern area was less

influenced by human activity. Stone coral growth in this area was supported by currents and waves from the Malacca Straits.

Compared to the other areas, the northern area was more influenced by tourism activities, which hindered coral growth.

Condition of coral cover was categorised as

good. The condition was better on the east of the island than on the north and west. In general, conditions here differed little from those at a depth of 3m, apart from a few physical factors such as light penetration and current velocity which put a limitation on coral growth. (2004)

(The relationship between the crown-of- thorns starfish Acanthaster planci and percentage of coral cover in the waters off Sabang, Pulau Weh island, Aceh. Dissertation, Dept. of Marine Science & Technology, Faculty of Fisheries and Marine Science, Bogor Agricultural University)

Crown-of-thorns starfish Acanthasther

planci were found to be distributed in the

Sabang waters at six stations (11 observation points) out of the ten Zooxanthellae Expedition VII research stations; the 6 stations were: Northeast of Rubiah, Northwest of Rubiah, North of Pulau Seulaku island, Ujung Batee Merunrung, Benteng, and Batu Dua. Only one species of Acanthasther was found i.e. red-purple Acanthasther totalling 29 individuals with diameter ranging from 24 cm to 52cm, although the size most frequently found was about 50 cm. The largest amounts of Acanthasther planci

were found at the station NW of Rubiah island at a depth of 10 metres. (2005)

Where as many as 12 individuals were found, it is estimated that the crown-of- thorns starfish could destroy 425m2 during

the following 3 months.

At the other stations, with one to five individuals, Acanthasther planci has a positive role in balancing the growth of fast growing Acropora coral, thus protecting biodiversity.

Achanturidae (10 species) (2004)

East of Pulau Rubiah island

2,926 coral reef fish from 108 species at depth of 7-10 metres (2006)

The general condition of coral reef in the Pulau Weh waters shows signs of

improvement, and no causes were found for new damage, as indicated by the low RKC

(Recently Killed Coral) variable.

Nevertheless, UPC (Upturned Coral) was still the dominant variable in coral damage due to the tsunami.
