Remark: We were there for only 2 days, we did just 3 dives before leaving for Lembeh Island on the other side(East) of North Sulawesi. Wall diving is the main attraction of Bunaken with many vertical cracks and canyons. Reef top sheltered from waves, with many differently shaped hard corals. I find diving at Bunaken pleasant. However our main purpose there was Lembeh straits, so without wasting to much time there, we headed for Lembeh Straits on the afternoon of day 2.
From Wikipedia, the free encyclopedia
Bunaken is part of the Bunaken National Marine Park, which has some of the highest levels of marine biodiversity in the world. Scuba diving attracts many visitors to the island. Bunaken is located at the north of the island of Sulawesi, Indonesia. It belongs administratively to the municipality of Manado.
The Bunaken National Marine Park was formally established in 1991 and is among the first of Indonesia's growing system of marine parks. The park covers a total surface area of 890.65 km², 97% of which is overlain by sparkling clear, warm tropical water. The remaining 3% of the park is terrestrial, including the five islands of Bunaken, Manado Tua, Mantehage, Nain and Siladen. Although each of these islands has a special character, it is the aquatic ecosystem that attracts most naturalists.
The waters of Bunaken National Marine Park are extremely deep (1566 m in Manado Bay), clear (up to 35-40 m visibility), refreshing in temperature (27 to 29 °C) Pick any of group of interest - corals, fish, echinoderms or sponges - and the number of families, genera or species is bound to be astonishingly high. For example, 7 of the 8 species of giant clams that occur in the world, occur in Bunaken. The park has around 70 genera of corals; compare this to a mere 10 in Hawaii. Although the exact number of fish species is unknown, it may be slightly higher than in the Philippines, where 2,500 species, or nearly 70% of all fish species known to the Indo-western Pacific, are found.
Other sides of Bunaken.Oceanic currents may explain, in part, why Bunaken National Marine Park is such a treasure trove of biodiversity. Northeasternly currents generally sweep through the park but abundant counter currents and gyros related to lunar cycles are believed to be a trap for free swimming larvae. This is particularly true on the south side of the crescent-shaped Bunaken Island, lying in the heart of the park. A snorkler or diver in the vicinity of Lekuan or Fukui may spot over 33 species of butterfly fish and numerous types of groupers, damsels, wrasses and gobies. The gobies, smallish fish with bulging eyes and modified fins that allow them to attach to hard surfaces, are the most diverse but least known group of fish in the park.
Biologists believe that the abundance of hard corals is crucial in maintaining the high levels of diversity in the park. Hard corals are the architects of the reefs, without them, numerous marine organisms would be homeless and hungry. Many species of fish are closely associated with particular types of corals (folious, branching, massives, etc.) for shelter and egg-laying. Others, like the enormous Bumphead Parrotfish, Balbometopon muricatum, are "coralivores" and depend on hard corals for their sustenance. Bony mouth parts fused into an impressive "beak" allow these gregarious fish to crunch corals like roasted peanuts.
Some 20,000 people live on the natural resources of Bunaken National Marine Park. Although there are inevitable conflicts between resource protection and use by people, the Indonesian government is taking a fairly unusual and pragmatic approach to park management. The idea is to promote wise resource use while preventing overexploitation. Local communities, government officials, dive resort operators, local nature groups, tourists and scientists have played an active role in developing exclusive zones for diving, wood collection, fishing and other forms of utilization. Bunaken Marine Park has become an important example of how Sulawesi, and the rest of Indonesia, can work to protect its natural resources.
