The trees are made out of PVC piping and resemble white Christmas trees. Each tree can hold up to 100 corals. The trees float in the water, attached to an anchor with a rope, and can move with storm-generated wave surges, even surviving hurricanes.
Coral nursery builders take snippets of “tough corals” – those that have survived bleaching and disease. The snippets are then tied onto the tree branches and left to grow at the nursery for a year or so, and cleaned at least once a month.
They hope the coral snippets will turn into “basketball sized” corals within a year. When the corals are grown, most are moved from the nursery and planted onto reefs, while the rest are cut into snippets to keep the nursery going.
The goal is to keep the nurseries continuously producing coral by getting recreational divers involved in the process.
Tioman is the third largest Malayasian island, off the east coast of the peninsula. The island is about 38 by 19 km. There is a road which extends about 3-4 km past the airstrip and ferry terminal and a couple of km either side. It connects the villages of Tekek and Juara, however all other villages are accessible only be ferry boat. The coast is a marine park area with a limit of 2 nautical miles offshore for commercial fishing. The water is warm, from 27 to 29 oC. There is only 1 ATM on the island, so it is best to bring some cash with you and check with your resort and dive centre is they accept cards as many places do not. Exchange currency before you get to the island (in Mersing) as you won't get a good exchange rate on Tioman.
The season runs from early February to November, the out of season time is associated with unpredictable weather during the monsoon. The best time of the year for visibility is March – June and visibility may drop in July and August.
Typically visibility is between 15-20 meters, but sometimes drops to 5 meters for no very obvious reason.
If nudibranchs are your thing you'll be happy at Tioman.

Jellyfish stings are responsible for more deaths than shark attacks each year. Even “mild” stings can hurt for hours to days and leave lasting scars. According to some estimates, more than 150 million people are stung by jellyfish each year.

Jellyfish stings are responsible for more deaths than shark attacks each year. Even "mild" stings can hurt for hours or sometimes days and leave lasting scars. According to some estimates, more than 150 million people are stung by jellyfish each year.
Researchers have now found overwhelming evidence that applying hot packs, or immersing in hot water, is much better for treating jellyfish stings than cold water which was previously widely recommended.
The scientists, Christie Wilcox and Angel Yanagihara from the University of Hawaii at Manoa, trawled through more than 2,000 articles in major scientific journals to find every study to date that examined the effects of using temperature-based treatments for jellyfish stings. They found that the data supported immersing in hot water, finding that venom components are inactivated at temperatures between 40 and 50 degrees Celsius.
"I was shocked that the science was so clear, given that there is so much debate over the use of hot water," said Wilcox. Hot-water immersion is already the standard of care for other severe marine stings including those from the potentially life-threatening stonefish. "It's simple, really: If you're stung, use hot water or hot packs rather than ice or cold packs."
The scientists conclude that immersing a stung limb in 45 oC water for 20 minutes has no ill effects, is a safe and effective method of reducing pain and improves the outcome of the sting.
The research was published this month in the journal Toxins
