The Japan Office (Minato-ku, Tokyo, Japan Director: Paul Summers) of the Queensland Tourism Board (Brisbane, Queensland, Australia, Acting CEO: Olly Philpott) is holding the annual coral It was announced that spawning was recorded for the first time this year on the Great Barrier Reef, east of Cairns, late on Friday, November 22nd. During coral spawning, which takes place every November during the full moon, the Great Barrier Reef’s magnificent corals release trillions of eggs and sperm into the water, creating an underwater ‘blizzard’ of new life. . As spawning occurs one after another over the course of the night, billions of tiny pink balls are released into the ocean, starting the regeneration process for many different types of coral. Naturalist Sir David Attenborough described it as “one of the greatest shows of all nature”. Coral researchers are looking for ways to increase reef regeneration to protect this natural icon from the increasing impacts of climate change, and coral spawning is also the most important day of the year for them. . This year, for the first time, a team from the Australian Institute of Marine Science (AIMS) is using a coral larval seeding technique called Coral IVF to increase the number of coral larvae produced by spawning. We provided guidance to contractors and those involved in the marine industry. This IVF involves collecting millions of coral eggs and sperm overnight in specially designed floating larval pools set up in two locations, with the aim of aiding the reef’s natural regeneration process. . The delicate bundles of eggs and sperm spend a week in a nursery pool before developing into coral larvae. It is then placed on top of the reef. The reef also includes areas affected by recent bleaching events, where corals grow into healthy young corals, bringing new life to the Great Barrier Reef. According to researchers, in a natural environment, the probability of successful fertilization is approximately 1 in 1 million, but with this Coral IVF technology, the probability of successful fertilization is increased to approximately 1 in 10,000, which is 100 times higher than in the natural environment. Anna Marsden, Executive Director of the Great Barrier Reef Foundation, said: “Last summer, the Great Barrier Reef suffered another
catastrophic bleaching event, underscoring once again that coral reefs are on the front lines of climate change. It is critical to develop a toolkit of solutions to protect against the effects of change. A collaboration between scientists and tourism operators called Boats4Coral, being piloted in the Whitsundays through the Foundation’s Reef Islands Initiative, is paving the way to overcoming the biggest challenge in coral reef restoration: scale. It opened. Following this success, we are implementing a similar approach in other parts of the Great Barrier Reef with support from Qantas. By adding this technology to their current conservation toolkit, enthusiastic tourism operators and locals hope to expand the region’s scalable, science-backed coral restoration movement.” Reef conservation efforts are funded by the Australian Government’s Reef Trust and the Australian Institute of Marine Science, and supported by Qantas in a 10-year, $10 million partnership with the Great Barrier Reef Foundation. . The Coral IVF project uses technology developed through the Coral Reef Restoration and Adaptation Program, funded by the Australian Government’s Reef Trust and Great Barrier Reef Foundation partnership and supported by Qantas. The Great Barrier Reef is Australia’s largest and most valuable natural icon, and according to Foundation research, it contributes $6.4 billion annually to the Australian economy, 90% of which comes from tourism. Supporting over 64,000 jobs. In order to establish a cycle in which the large number of tourists visiting from Japan will revitalize the local tourism industry, including the leaf tax, and contribute to such initiatives, the Queensland Government Tourism Board will also receive assistance from Japan. We are working hard to encourage even more people to travel. ■What is coral spawning? Coral spawning is the birth of new life on the Great Barrier Reef. It is a fascinating natural phenomenon that occurs once a year and has been likened to an underwater snowstorm. In late spring, corals on the Great Barrier Reef release eggs and sperm, which slowly rise to the surface in small balls. Spawning occurs only at night when
plankton-eating reef fish are sleeping, reducing the risk of eggs being eaten. They form a pink-brown oil slick on the sea surface, where their sperm meet compatible eggs and give birth to larvae, which mature into coral polyps in about 10 days. Many of these small bundles will become young corals, offering hope for the future of the Great Barrier Reef. Although stories about coral spawning have been passed down by indigenous people along the coast, the fact was completely unknown until 1982, and even today, there is still much that is unknown about this phenomenon. Coral reefs near the coast tend to spawn a month earlier than coral reefs on the outer reef, where spawning is more common. On the outer reefs off Cairns and Port Douglas, spawning typically occurs two to six days after the full moon in November, when water temperatures are 27-28°C. ■To see coral spawning Tour operators offer night diving and snorkeling tours during the period when coral spawning is expected. Diver’s Den and ProDive Cairns, Tusa operated night tours during the coral spawning season in November and December 2023, as well as liveaboards to the Great Barrier Reef. Since it is a natural phenomenon, there is no guarantee that you will see coral spawning, but you can enjoy your cruise while spotting the sea creatures that appear after sunset. Information on coral spawning is also introduced on the Queensland website.
https://www.queensland.com/jp/ja/places-to-see/experiences/great-barrier-reef/coral-spawning About Queensland The state of Queensland, with a population of approximately 5.3 million people and an area approximately 1/4 of Australia, is located in the northeast and is home to popular tourist destinations such as Cairns, Brisbane, the Gold Coast, and the Great Barrier Reef. The climate is warm throughout the year, and the time difference with Japan is only one hour, making it easy to travel to and from Japan. Please check the homepage for more detailed
