“For the Florida Keys’ reefs, overall, the live coral cover has diminished by 50 to 80 percent in the past 10 years,” says Margaret Miller, a coral reef researcher at the National marine Fisheries Service. According to Miller, the destruction is the result of several contributing factors, such as pollution, climate change, over-fishing, and coastal developments.

“Corals are very susceptible to warming temperatures, because their lethal temperature [temperature at which they die] and their happy, normal temperature are very close, only separated by a couple of degrees,” Miller explains.

The reef building corals are not the only creatures in trouble in Florida; the situation looks dire for many reef associated species as well.

University of Miami marine professor Jerry Ault has studied marine life in the region for more than a decade.
“The research has discovered that about 70 percent of all the snapper and grouper in the Florida keys reef system are at population levels below those considered to be sustainable,” he said. “Everybody loves Florida because of the marine environment. Folks come here to fish and to dive and to take advantage of it, but we are loving it to death.”

1.2 million tonnes of coral may have been illegally extracted from reefs located near Malaysia’s protected Semporna Islands Park.

State Tourism, Culture and Environment Minister Datuk Masidi Manjum has formed a committee that will investigate the allegations made by former state Social Services Minister Datuk Kong Hong Ming.

According to the former minister, corals have been extracted for 10 years by a certain group under the pretext of dredging sea sand. The corals have then been ground up and the powder sold to medical and pharmaceutical companies to be used for bone surgery, dentistry and drugs. Kong Hong Ming also said that he has visited an area in Tawau where 1,000 tonnes of corals were stored and that all corals were moved two days after his visit.

Manjum has now given the committee, headed by his minister Deputy Permanent

Secretary William Bayo, three weeks to wrap up its investigation.

“This is a very serious matter. I do not want to prejudice the probe by saying any more about it,” Masidi said Thursday.

Semporna Islands Park, also known as the Tun Sakaran Marine Park, is home to one of the nation’s prime coral reefs and the surrounding area is also very rich in biodiversity.

A study proposing a ban on spear guns and gill nets in the Great Barrier Reef is now being criticised by Australian scientists saying its results – which were obtained from Kenya and Papua New Guinea – aren’t relevant to the Great Barrier Reef.

The study, carried out by an international team of scientists led by Dr Josh Cinner from the ARC Centre of Excellence for Coral Reef Studies, proposed a ban on fishing gear such as spear guns, fish traps, beach seine nets, and gill nets to aid damaged reefs in their recovery. According to data obtained from the waters of Kenya and Papua New Guinea, certain types of fishing gear are more damaging to corals and to certain species of fish needed to help reefs recover from bleaching or storm damage.

“They [corals and certain types of reef fish] are already on the edge because of the overfishing and the additional impact caused by a bleaching even can push them over,” said Dr Cinner, who is based at James Cook University.

According to Dr Josh, spear guns are the most damaging of all fishing gear, particularly to fish that help maintaining the reef by removing seaweeds and sea urchins.

“Spear guns target a high proportion of species that help maintain the resilience of coral reefs, but also can result in a surprising amount of damage to the corals themselves,” Dr Cinner said. “When a fish is shot with a spear gun, it often hides in the reef, so some fishermen break the corals in their attempts to get it.”

Not applicable to the Great Barrier Reef, says other scientists Fellow JCU fisheries scientist Dr Andrew Tobin do not agree with the fishing gear ban recommendation, saying that the results from the study aren’t applicable to Australia’s Great Barrier Reef.

“Some of those findings are probably very reasonable for those areas they’ve studied, but to make any link to Great Barrier Reef waters is probably drawing a very long sword,” Dr Tobin said.

According to Townsville marine biologist Dr Walter Starck, who provides advice to Sunfish North  Queensland, herbivore fish aren’t being overfished in the Great Barrier Reef area.

“Here in Australia, it is completely irrelevant,” he said.

300,000 pounds of rock has been stolen from the bottom of the ocean near Alligator Light and Islamorada off the coast of Florida.

The Florida Fish and Wildlife Conservation Commission and the Monroe County Sheriff’s Office wish to hear from anyone who may have seen a boat harvesting the material from the site. If you have any information about this case, please contact FWC, the

Sheriff’s Office or call the Crime Stoppers of the Florida Keys at (800) 346-TIPS. You can also leave an anonymous tip at https://www.tipsubmit.com/.

The stolen rocks belong to Neal Novak, 51, a Miami aquarist who leases the quarter-acre site inshore of Alligator Reef from the federal government to cultivate live rock for the aquarium trade. Unfortunately, Novak hasn’t visited his farm in a year so it is hard to know when the theft took place.

Live rock consists of dead coral rock or quarried rock colonized by a profusion of marine species. Anything from tiny bacteria to large sponges can find a home in and on this type of “living” rock, and rocks covered in colourful coralline algae are especially coveted. Saltwater aquarists use live rock to make their aquariums look more beautiful, make the ecosystem more balanced, and help keep the water quality up in the tank. Live rocks are often colonized by scavenging species that will take care of any left-over food in the aquarium before it gets a chance to foul the water. According to Novak, the wholesale price for quality live rock in Florida is about $3 per pound.

Since the harvest of live rock from the wild can hurt marine environments, Florida banned it in the 1990s and state and federal governments decided to lease barren sea-bottom sites to people interested in aqua-culturing live rock for the aquarium trade.

Novak created his live rock farm by purchasing rock from quarries in south Miami-Dade County and ferrying them to his farm where the rocks have been resting in roughly 20 feet (6 metre) of water until someone took them. The rock pile, which was designated by GPS coordinates, has most likely not been moved by natural forces, because no hurricanes have been reported from the area since 2005 and a second stone pile with immature live rock was left largely intact.

With a wholesale price of $3 per pound, 300,000 pounds of rock can naturally give a tidy little profit for unscrupulous boulder thieves.

“They stole my livelihood,” Novak said. “This is devastating to my whole family. It cost me almost $150,000 to put the rock down and start the business. I spent my life savings to make this work. We could be looking at bankruptcy.”

Dubai‘s largest reef, consisting of over 1,100 coral-encrusted rocks, has been moved to a new location to protect it from future development. Details of the relocation have been kept secret for more than a year to ensure its success, and the transfer was therefore not announced until today, on World Environment Day.

not the reef in the article!

Oddly enough, no one seems to have known about the existence of the reef until Dubai real estate development company Nakheel conducted an environmental assessment of Dubai Dry Docks’ breakwater.

“What we found [in the initial assessment] was the biggest coral reef in Dubai and an area of extreme importance, said marine biologist John Burt, Assistant Professor at Zayed University, who was brought on board as an independent expert. “Because of the conditions in the Gulf – where the water temperature can reach 35C and drop to 15C – coral has difficulty establishing itself. However, it has learned to adapt and we believed it was important to do everything we could to protect this reef.”

Moving 1,129 rocks

Traditional methods of moving corals were quickly dismissed, since they typically result in the death of up to 30 percent of the corals. Instead, Nakheel and their team of engineers and scientists decided to remove, lift and transport the corals by barge without ever taking them out of the water.

“Traditionally, when coral is moved it is chiselled or drilled from rocks, placed in baskets and shipped to a new location,” said Brendan Jack, Head of Sustainability and Environment for Nakheel Northern Projects. “That wasn’t open to us because each of the rocks was encased in coral, so we went back to the drawing board to find an engineering solution. Nothing like this has ever been attempted before and we are very pleased with the outcome.”

The project took five weeks to complete and involved engineers and divers drilling an iron bolt into each and every one of the rocks and attaching it to a sling. After being hoisted from its resting place, each rock had its sling fastened to one of several mountings welded to the deck of a 90-metre barge. Thanks to this new method, the coral rocks could be moved to their new home at The World’s breakwater without ever leaving the water.

With no more than 20 rocks being transported to The World at a time; it took 50 days to move the 1,129 rocks – each of them weighing about five tonnes. Sadly enough, some rocks had to be left behind since they could not be reached by the marine crane.

“We could not take all of the coral,” said Burt. “In some places the water was too shallow for the crane so the rocks had to be left. I believe once development around the Dry Docks breakwater begins the remaining coral has no chance of survival.”

The result

Initial studies of the relocated coral have been very promising and so far the project seems to have been successful. As mentioned above, up to 30 percent of the coral usually give up the ghost when traditional relocation methods are used but in the case of the Dubai reef only 7 percent of the corals have died. Independent scientific study of the coral is continuing and a scientific peer-reviewed research paper will be published once the study is complete in the coming months.

The future

The World, where the coral reef is now residing, is a man made archipelago of 300 islands constructed in the shape of a world map and located 4 km off the coast of Dubai. The total area now covered by coral at The World is 6,560 square metres and this number may increase as corals begin to colonize nearby surfaces.

“A number of the dominant corals, now at The World, are ‘broadcast spawners’ and their reproductive activities could result in the development of coral on nearby rocks”, said a Nakheel spokesman.

The exact location of the relocated reef is still being kept secrete to avoid attracting commercial and recreational fishermen. However, once the new coral colony is firmly established it may be opened up for scuba diving and similar activities.

Hundreds of thousands of tourists visits Green Island each year to enjoy scuba diving and snorkelling among its beautiful reefs, but no sewage treatment exists so an average of 1,500 tons of untreated sewage is flushed into the sea on a daily basis.

According to The China Post , no sewage treatment project has been prepared for the island since land can’t be procured for a sewage plant. Researchers now fear that the untreated sewage is to blame for the spread of the so called “Black Death” among the corals.

Chen Jhao-lun, a senior research fellow at the Academia Sinica who has studied the coral
reefs, describes the affected colonies as being covered slowly with a piece of black cloth.
“As this black sponge which multiplies itself covers the colonies, it shuts off sunlight to stop
photosynthesis by coral polyps,” Chen explains. The polyps die and no new corals are formed.

The “Black Death”, a type of necrosis, typically manifests in the form of black lesions that gradually spread across the surface of an infested colony.

However, very little is known about the Black Death and some researchers think that other factors, such as changing water temperatures or overfishing, might be to blame – not the untreated sewage. It is also possible that a combination of unfavourable factors have tipped the balance of the reef, causing the disease to go rampant. Temperature does appear to be a key variable associated with outbreaks, but it remains unknown if a temperature change alone is capable of causing this degree of devastation.

Molecular studies on lesions have not been able to identify a likely microbial pathogen, and according to Chen, the black layer might actually be an opportunistic second effect rather than the causative agent of the coral mortality. Montipora aequituberculae corals seem to be especially susceptible to the disease, but at least five other coral species from three different genera have been affected as well.

When Chen surveyed the water of Green Island last year, only four colonies off Dabaisha or Great White Sand showed signs of Black Death. In April this year, Chen found 24 affected colonies – six times as many as last year. If nothing is done to remedy the problem, Great White Sand near the southernmost tip of Green Island may have only dead colonies in five to six years, Chen predicts.

Green Island
Green Island is known as one of the world’s best spots for scuba diving and snorkelling. Located roughly 16 nautical miles southeast of Taitung on east Taiwan, Green Island used to house a concentration camp for political prisoners. Today, it is instead famous for its rich coral reefs.

Eleven suspected abalone poachers have been arrested in northern California, officials said Friday.

Since the tide was unusually low in Mendocino County, California Department of Fish & Game wardens were aware of the increased risk of poaching activity and kept their eyes on the coast line, including the coral reefs that had become exposed as the water disappeared.

At about 6.15 a.m. on Wednesday wardens noticed suspicious divers exiting waters near Caspar, south of Fort Bragg. Fish & Game Lt. Kathy Ponting, who runs the special operations unit, said her team drove to a spot near the suspicious divers and began surveillance.

Unaware of the wardens’ presence, the divers collected abalone from the reef and placed them in tall grass near the beach.

“Then a large van pulled up near the dive area and we watched them load up a bunch of abalone in plastic bags into the van,” Ponting said. The divers went back to the sea, while wardens decided to follow the van. After pulling it over, they discovered 50 abalones inside.

Abalones can sell for up to $100 dollars, but collection is strictly regulated since these molluscs need many years to develop. It can take 12 years for a specimen to reach the legal size. With a California fishing license and an abalone stamp card you are allowed to fetch 24 specimens per year, but no more than three per day. It is also illegal to collect them for sale, and anyone caught with a dozen or more will be considered possessing them with the intention of selling them.

Red Abalone. The only type that can be harvested.

When the van did not return to the divers, the alleged poachers loaded a pickup truck. The wardens followed the car to a nearby hotel and found coolers filled with abalone inside the divers’ hotel room. Most of the abalones were smaller than the legal size.

The wardens found a total of 166 abalones with the group, Ponting said. The suspects were booked on charges of felony conspiracy to harvest abalone for commercial purposes, which carries a fine of up to $40,000, said Game Warden Patrick Foy. Two vehicles also were

seized along with $6,000 in cash.

The black market for abalone is large and poaching is widespread, despite official efforts to eradicate the practise.

“We always only catch the tip of the iceberg, there is so much

abalone poaching going on because of the black market,” Ponting

explained. “We can pick almost any group and watch them poaching

abalone. It’s really unsettling.”

What is an abalone?

The abalone is a medium sized to very large edible sea snail prized for its exquisite flavour. There is roughly 100 known species world wide, all of them being gastropod molluscs belonging to the genus Haliotis. You may stumble upon a species marketed as “Chilean abalone” in the food trade, but this is not a real abalone; its name is Concholepas concholepas and it belongs to an entirely different family.

Since abalones are found in so many different parts of the world, they are known under many different names, such as abulón in Spanish, ormer in Jersey and Guernsey, pāua in

New Zealand, muttonfish or muttonshells in Australia, perlemoen in South Africa, and Venus’s-ears, ear-shells, and sea-ears in British and American English.

Abalones reach sexual maturity when they are comparatively small, but they won’t produce any significant amount of offspring until they grow bigger. A small abalone may release around 10,000 eggs at a time, which may sound like a big number but is dwarfed compared to the 11 million eggs released at a time by really large abalones. As a result of this, the removal of abalones from the sea before they have a chance to grow large is highly detrimental to the survival of the species.

Abalone has been farmed since the 1950s in Japan and China, and during the 1990s the practise spread to other parts of the world in response to dwindling wild populations. Today, it is possible to purchase farmed abalone and refrain from removing specimens from the wild. China and Japan are still major producers of abalone, but has been joined by Korea, Thailand, Australia, New Zealand, South Africa, Namibia, Iceland, Ireland, Canada, USA, Mexico, and Chile.

Catching abalone in California

As mentioned above, it is legal to fetch a certain amount of abalone per day and year in Californian waters if you have a California fishing license and an abalone stamp card. The abalone stamp card has 24 tags and captured abalones must be tagged immediately. The legal size is (a minimum of) seven inches (178 mm) measured across the shell. A person may be in possession of no more than three abalones at any given time. Other regulations to keep in mind are listed below. Always check with the California Department of Fish & Game before you go abalone hunting in California to find out if there have been any regulatory changes.

· Scuba diving for abalone is always prohibited; you may only pick them from the shore or use breath-hold techniques.

· Abalone may only be taken from April to November, not including July.

· You may only take Red abalones; no Black, White, Pink, or Flat abalones.

· You may not take any abalones south of the mouth of the San Francisco Bay.

· You may not sell any part of the abalone, including the shell.

· Only abalones still attached to the shell can be legally transported.

The intricate symbiotic relationship between reef building corals and algae seem to rely on a delicate communication process between the algae and the coral, where the algae is constantly telling the coral that the algae belongs inside it, and that everything is fine. Without this communication, the algae would be treated as any other invader, e.g. a parasite, and be expelled by the coral’s immune system.

Researchers now fear that increased water temperature will impair this communication system, something which might prove to be the final blow for corals already threatened by pollution, acidification, overfishing, dynamite fishing, and sedimentation caused by deforestation.

According to a new report, a lack of communication is likely to be the underlying cause of coral bleaching and the collapse of coral reef ecosystems around the world.

Reef building corals can defend themselves and kill plankton for food, but despite this they can not survive without the tiny algae living inside them. Algae, which are a type of plants, can do what corals can’t – use sunlight to produce sugars and fix carbon through photosynthesis.

“Some of these algae that live within corals are amazingly productive, and in some cases give 95 percent of the sugars they produce to the coral to use for energy,” said Virginia Weis, a professor of zoology at Oregon State University. “In return the algae gain nitrogen, a limiting nutrient in the ocean, by feeding off the waste from the coral. It’s a finely developed symbiotic relationship.

If this relationship were to collapse, it would be death sentence for the reef building corals.

Even though the coral depends on the algae for much of its food, it may be largely unaware of its presence, said Weis. We now believe that this is what’s happening when the water warms or something else stresses the coral – the communication from the algae to the coral breaks down, the all-is-well message doesn’t get through, the algae essentially comes out of hiding and faces an immune response from the coral.”

This internal communication process, Weis said, is not unlike some of the biological processes found in humans and other animals.

Researchers now hope that some of the numerous species of reef building corals found globally and their algae will be more apt at handling change.

“With some of the new findings about coral symbiosis and calcification, and how it works, coral biologists are now starting to think more outside the box,” Weis said. “Maybe there’s something we could do to help identify and protect coral species that can survive in different conditions. Perhaps we won’t have to just stand by as the coral reefs of the world die and disappear.”

The new research has been published in the most recent issue of the journal Science and was funded in part by the U.S. National Science Foundation.

A sinking date has now been set for the retired military vessel scheduled to form an artificial reef off Key West in Florida. If everything goes according to plan, Gen. Hoyt S. Vandenberg – a 523-foot-long military ship that used to track Russian missile launches during the Cold War – will be sunk seven miles (11 km) south of Key West on May 27.

“Our sink window opens Wednesday, May 27, and that’s the date we’re currently targeting,” said Jim Scholl, Key West’s city manager and project administrator. “However, there are factors that could delay the scuttling, including weather and other unforeseen circumstances.”

A definite time for the sinking has not yet been set, but the event will probably take place during late morning, officials said.

During the sinking, a one-mile perimeter will be enforced on the water and in the air by the U.S. Coast Guard, the Florida Fish and Wildlife Conservation Commission, and other U.S. law enforcement agencies.

Gen. Hoyt S. Vandenberg is currently waiting in Key West Harbor.

Indonesia will create Southeast Asia’s largest marine park in the Savu Sea, Minister of Marine Affairs and Fisheries Freddy Numberi said on Wednesday at the World Ocean Conference in Manado, Sulawesi.

The Savu Marine National Park will cover 3.5 million hectares in an incredibly diverse area where you can find no less than 500 coral species, over 300 recognized species of fish and a lot of charismatic wildlife like sea turtles, sharks, dolphins and whales. Out of 27 known species of whale, no less than 14 migrate through the Savu Sea to get from the Pacific to the Indian Ocean. The Savu Sea is also an important spawning ground for many marine species, including the world’s dwindling tuna population.

Indonesia is famous for its prosperous marine environment, but this marine flora and fauna are today facing serious treats, including pollution, over fishing and the use of unsustainable fishing methods. Lax enforcement of Indonesian law has made it possible for fishermen to continue using illegal fishing methods such as dynamite and cyanide fishing.

Within the Savu Marine National Park, efforts will be made to eradicate illegal fishing practises while keeping certain areas open for local fishermen to continue traditional subsistence fishing. Tourism activities will also be allowed in certain designated areas within the park. Environmental groups, including WWF and The Nature Conservancy, will help set up the reserve together with the Indonesian government.

“Enforcement is one of the key questions we need to work out, said Rili Djohani”, marine expert at The Nature Conservancy. “It could be a combination of community-based and government patrols.”

The Savu Marine National Park is located within the so called Coral Triangle, a coral reef network bounded by Indonesia, Malaysia, the Philippines, Papua New Guinea, East Timor and the Solomon Islands.
