NDO – The Ba Ria - Vung Tau province is conducting a rehabilitation of the coral reef at the Ramsar area of Con Dao National Park, according to the Department of Science and Technology of Ba Ria – Vung Tau province. After completion, the coral reefs in the Con Dao marine area will be revitalised, followed by a restoration of marine biodiversity, especially of living aquatic species. Meanwhile, reproduction in coral reefs will grow and marine resources will be reproduced rapidly. The Department of Science and Technology of Ba Ria - Vung Tau province will coordinate Con Dao National Park to organise communication training courses in order to raise community awareness in restoring and protecting coral reefs in the region. Earlier, according to the management board of Con Dao National Park in Ba Ria - Vung Tau province, a large swathe of coral reef in Con Dao have suffered bleaching and it is estimated that reef die off extends to an area of about 600ha to 800ha. … [Read more...] about Ba Ria – Vung Tau restores coral reefs
Why does coral bleaching occur
The planet's coral reefs are likely facing warmer than normal water for an unprecedented third year in a row, extending what is already the longest coral bleaching event on record, US observers said Monday. The global bleaching event began in mid-2014 with global warming and a particularly intense El Nino phenomenon resulting in higher than normal ocean temperatures, according to the National Oceanographic and Atmospheric Administration. NOAA presented its grim outlook for the world's coral reefs at an international symposium being held this week in Honolulu, Hawaii. It said the impact is expected to be particularly hard on reefs in US states and territories. Reefs in Hawaii, Guam, the Northern Marianas, the Florida Keys, the US Virgin Islands and Puerto Rico are particularly vulnerable. "Since its onset, all US coral reefs have seen above normal temperatures and more than 70 percent of them have been exposed to the prolonged high temperatures that can cause bleaching," NOAA said. It … [Read more...] about Coral bleaching goes into unprecedented third year: NOAA
BÀ RỊA - VŨNG TÀU - El Nino-triggered coral bleaching has spread to approximately one fourth of coral reef areas around Côn Đảo Islands off the southern province of Bà Rịa-Vũng Tàu since March. The worst bleaching occured in May. According to the management board of the Côn Đảo national park, eight major areas - including Côn Sơn bay, Đầm Tre and Hòn Tre Lớn seas - are affected. The weather phenomenon causing the water surface to become unusually warmer has so far affected up to 500 hectares of local coral reefs, with an average of between 30 and 40 per cent of corals bleached in hard-hit areas. Bleaching stunts the growth of corals and makes them prone to diseases and reproduction vulnerability; in severe cases, it kills them. Studies by the maritime conservation department show that most Porites, round-shaped Fungiidae and Poritidae corals in these locations were completely bleached and at high risk of dying. Pocillopora corals, meanwhile, have mostly been bleached on their … [Read more...] about Con Dao island corals bleached by El Nino
Peter Gash, owner and manager of the Lady Elliot Island Eco Resort in the Great Barrier Reef area, snorkels during an inspection of the reef's condition in an area called the 'Coral Gardens' located at Lady Elliot Island, Australia, in this June 11, 2015 file photo. Reuters/David Gray/Files Australian scientists said on Wednesday that just seven percent of the Great Barrier Reef, which attracts around A$5 billion ($3.90 billion) in tourism every year, has been untouched by mass bleaching that is likely to destroy half the coral. Bleaching occurs when the water is too warm, forcing coral to expel living algae and causing it to calcify and turn white. Mildly bleached coral can recover if the temperature drops, otherwise it may die. Although the impact has been exacerbated by one of the strongest El Nino weather systems in nearly 20 years, scientists believe climate change is the underlying cause. "We've never seen anything like this scale of bleaching before. In the northern Great … [Read more...] about Half Australia’s Great Barrier Reef coral “dead or dying” – scientists
Over only less than a month, bird flu has reoccurred in ten provinces. Why does the epidemic reoccur in a large scale and in summer; bird flu usually breaks out in the cold season. To explain the problem, the Ministry of Agricultural and Rural Development (MARD) met on May 28 to urgently implement measures to prevent bird flu. The meeting was attended by related agencies and representatives from provinces and cities. Let the grass grow under one's feet Although the National Steering Committee for Bird Flu Control and Prevention warns that localities must carry out bird flu prevention measures frequently because the H5N1 virus always exists in environment, in healthy waterfowl and may break out at any time. However, awareness of epidemic prevention in localities remains low and major localities still let the grass grow under their feet, meaning bird flu breaks out. Bird flu has just reoccurred in northern Ninh Binh province. The epidemic broke out from 550 unvaccinated young ducks … [Read more...] about Why does bird flu reoccur in the hot season?
