The rare Gangetic dolphin (Platanista gangetica) has been declared National Aquatic Animal of India. A few days after the formal declaration, which took place at a National Ganga River Basic Authority meeting in New Delhi earlier this week, Bihar chief minister Nitish Kumar announced that he has directed state authorities to put a halt to dolphin hunting in the Ganga.
“A close watch is being kept on the ghats of river Ganga by the magistrates, police officials and block development officers to stop hunting and fishing of the mammals,” senior officials said.
Patna District Magistrate J K Sinha said that instructions from chief minister has been passed
to senior officials, including sub-divisional officers, magistrates, police officers and block development officers to ensure close surveillance and act swiftly to stop hunting of the aquatic animal.
“Schools will take steps to aware the students about the gangetic dolphin which would
boost eco-tourism in the region,” he added.
Although the Wildlife Protection Act of India mandates dolphin conservation as a priority, little has been done at the government level to implement or enforce the law.
Where is Bihar?
Bihar is an Indian state located in the eastern part of the country. It is bordered by Nepal to the north, Jharkhand to the south, Uttar Pradesh to the west, and West Bengal to the east. The state is bisected by the Ganga River which flows through the middle of the state from west to east.
What is Ganga?
Outside India, the Ganga River is more commonly known as the Ganges River.
What is the Gangetic dolphin?
The Gangetic dolphine, also known as Ganges dolphin, Ganges river dolphin, Blind dolphin, and Side-swimming dolphin, is a dolphin endemic to the Ganges-Brahmaputra-Meghna and Karnaphuli-Sangu river systems of Nepal, India, and Bangladesh. Its scientific name is Platanista gangetica and it is listed as Endangered on the IUCN Red List of Threatened Species. The current population consists of 1,200-1,800 individuals, and roughly half of these are found in Bihar and Uttar Pradesh.
It is referred to as the Blind dolphin due to its poor eye-sight which is probably an adaptation to the murky waters of the Ganga River.
The Maldives is planning to ban shark fishing in its waters, a move which would make the Maldives the first nation in the region to enact such a protective law.
The announcement was made by the Maldives Minister of State for Fisheries and Agriculture, Dr Hussein Rasheed Hassan, at the South West Indian Ocean Fisheries Commission steering committee meeting in Mombasa.
“We have realised that it is more economically viable to leave the shark and other sea creatures unharmed because the country currently earns about $7 million annually from the diving industry,” said the minister.
In 1998, the Maldives imposed a 10-year moratorium banning shark fishing around seven atolls that received a lot of vacationers from abroad. Now, the country intends to expand the ban to include all reef shark fishing across the Maldives within a 12 nautical mile radius (22km).
During recent years, the number of sharks in the Maldives has plummeted due to overfishing for the lucrative shark fin market.
“The marine ecosystem is very fragile and that is why we have to regulate activities that coupled with the treats of climate change could adversely affect the major sources of income for the country,” Hassan explained.
The Maldives is an island country consisting of a group of atolls stretching south of India’s Lakshadweep islands. Despite having a population of no more than roughly 300,000 individuals, the Maldives receives over 600,000 tourists each year.
Telling a wild salmon from a farmed one can be tricky, especially if you don’t want to kill or injure the fish in question. To solve this problem, Dr Elizabeth Adey of the Scottish Association for Marine Science (SAMS) have developed a way of using fish scale analysis to determine the origin of a salmon.
Fish scales grow like tree rings and preserves a chemical record of the water in which the fish lived as each new section of the scale was formed. The new method, which was developed in collaboration with the National Oceanography Centre in Southampton, checks the amount of manganese present in the fish scale. During her work, Dr Adey discovered that the scales of farmed salmon have a very high manganese content compared to the levels found in scales coming from their wild counterparts.
“This is probably caused by manganese supplements in fish food, and also because conditions underneath the fish cages promote recycling of manganese in the water column,” Dr Adey explains. Using the new method, Dr Adey and her team was able to distinguish between farmed and wild salmon with 98% accuracy.”Because of its non-destructive nature, this technique could be used to assess the proportion of farmescape salmon present in any river, and therefore identify where additional conservation and wildlife protection measures are needed,” says Dr Trueman, a geochemist with the University of Southampton’s School of Ocean and Earth Science, based at that National Oceanography Centre. “Salmon farming is a big, intensive business. In 2006, around 130,000 tonnes of salmon were farmed in Scotland for the table. Wild populations of Atlantic salmon are in serious decline across their whole range and the total wild population returning to Scottish rivers in the same year is estimated at less than 5000 tonnes. Wild fish are rare and expensiveso there is a strong incentive for fraudulent labeling. Farmed fish also escape into rivers, harming the wild population. Unfortunately, it can be difficult to distinguish between farmed and wild fish.“
In the future, the new technique may also be able to point out which individual fish farms that need to implement more efficient methods for keeping their salmons in. In some Norwegian rivers, more than 50 percent of the salmon are now escapees. Escaped fish can carry disease to wild populations, and there is also a risk of genetic pollution since farmed fish haven’t gone through the same natural selection process as wild fish.
A previously unknown field of endangered Staghorn coral has been found in Florida waters by scuba divers belonging to the non-profit group Palm Beach County Reef Rescue.
“We’ve found the largest field (of the coral) in the county,” says Reef Rescue’s director Ed Tichenor. “We’re really surprised by this.”
The field, which is located roughly a mile east of Palm Beach island, is significant since Palm Beach town officials have objected to federal protection of the area.
Last year, the National Marine Fisheries Service designated roughly 1,300 square miles of ocean floor – ranging from the Florida Key to the Boynton Beach Inlet – as critical habitat for staghorn. This prompted the Palm Beach County Reef Rescue to petition the government to extend the protected area northwards to the Lake Worth Inlet, thereby including the coast off Palm Beach.
The Palm Beach County Reef Rescue estimates the newfound staghorn field to be between 100 and 300 feet long.
“I was expecting to see it but not as much,” said Connie Gasque, a Palm Beach resident who led the dive group. “My reaction was ‘Wow!
Everywhere you looked, there it was.”
Before this discovery, only small pockets of staghorn coral was known to exist in the waters off Palm Beach.
Palm Beach County Reef Rescue now hopes that the discovery will convince the National Marine Fisheries Service to include the region in the protected coral zone.
What is Staghorn?
Staghorn (Acropora cervicornis) is a branching coral that can reach a length of up to 2 meters (almost 7 feet). It is the fastest growing species of all West Atlantic corals and can grow 10-20 cm per year in favourable conditions. The natural range for Staghorn coral stretches from Florida, USA through the Bahamas and the Carribbean Sea, down to Venezuela in South America.
Acropora cervicornis was placed on the U.S. Endangered Species List in 2006, and it is also listed as Critically Endangered on the IUCN Red List of Threatened Species.
According to the U.S. National Oceanic and Atmospheric Administration, staghorn is not found north of Boca Raton.
The world’s first shark sanctuary will be created by Palau, a small island nation in the Pacific Ocean. The sanctuary will measure 240,000 square miles and be a haven for vulnerable shark species like Leopard shark, Hammerhead, and Oceanic Whitetip. Over 135 different species of shark and ray is known to live in this biological hotspot.
“Palau will declare its territorial waters and extended economic zone to be the first officially recognized sanctuary for sharks,” said Palauan President Johnson Toribiong.
Unfortunately, this tiny nation with a population of 20,000 people has only one patrol boat to protect the immense sanctuary from fishermen.
While acknowledging the difficulties, the president still hopes that others will respect Palauan territorial waters – and that the shark haven will inspire more such conservation efforts globally.
“We’ll do the very best we can, given our resources,” he said. “The purpose of this is to call attention to the world to the killing of sharks for commercial purposes, including to get the fins to make shark fin soups, and then they throw the bodies in the water.”
Toribiong said a recent flyover by Australian aircraft showed more than 70 vessels fishing in Palau waters, many of them illegally.
Bermuda‘s first Lionfish Tournament resulted in just four participants returning with lionfish for the weigh-in. Although this might sound disheartening, it is actually happy news for Lionfish project leader Chris Flook of the Bermuda Aquarium, Museum and Zoo since it indicates a relative scarcity of lionfish in Bermuda waters.
Lionfish is an invasive species in the Caribbean where it lacks naturally predators and multiplies uncontrollably. In the Bahamas, female lionfish spawn twice a month. Lionfish Tournaments like the one just held in the Bermudas is a way to boost public awareness and decimate the number of lionfish in the Caribbean. A Lionfish Tournament held in the Bahamas a few weeks ago resulted in the catch of about 1,400 lionfish.
“If we’d caught 1,000 fish it would have been very concerning, because it means it’s happening here like everywhere else,” Flook explained. “It means we may be ahead of the game and are potentially managing the population here in Bermuda.”
However, Flook also said that one of the reasons why not many fish were caught Bermuda’s Lionfish Tournament could be that they were hiding in deep waters following the storm surge of the recent Hurricane Bill and Tropical Storm Danny.
Mr. Flook began the Lionfish Culling Programme last year to encourage divers and fishermen to hunt down the species. Organised by environmental group Groundswell, the ‘Eat ‘um to beat ‘um’ event also aimed to show how invasive lionfish can be utilized as a food source.
“I think everybody who tasted it was very for it. It’s a great tasting fish,” said Flook, as Chris Malpas, executive chef at the Bank of Butterfield, cooked up samples of speared lionfish at Pier 41.
“The tournament has got the message out and so now hopefully people might start asking for lionfish in restaurants and fishermen will bring them in rather than throwing them overboard.
By eating lionfish we will take the pressure off some of our commercial fish. Every one you take is one less eating our juvenile fish,” said Flook.
If you want to know more about spearfishing lionfish in Bermudas, contact the Bermuda Aquarium at 293-2727 ext. 127, or the Marine Conservation Officer at 293-4464 extension 146 or e-mail lionfish@gov.bm. The Marine Conservation Officer should also be contacted if you see a lionfish in Bermuda waters.
Thousands of Greenland sharks get caught and die in nest off Greenland each year, but their meat is toxic to humans and the carcasses are therefore thrown back into the sea.
Researchers at the Arctic Technology Centre (ARTEK) in Sisimiut in western Greenland now hope to find a way of turning the oily flesh of these enormous fishes into biogas for Eskimos.
The Greenland shark can reach a length of seven meters (23 feet) and weigh up to a tonne.
“I think this is an alternative where we can use the thousands of tonnes of leftovers of products from the sea,
including those of the numerous sharks,” says Marianne Willemoes Joergensen of ARTEK’s branch at the Technical University of Denmark.
Joergensen, who is in charge of a pilot project based in the Uummannaq village in northwestern Greenland, says a mixture of shark meat, macro-algae and household wastewater could serve as biomass for biofuel production.
“Biofuel is the best solution for this kind of organic waste, which can be used to produce electricity and heating with a carbon neutral method,” she explains.
According to estimates, biofuel from the sea could supply Uummannaq’s 2,450 inhabitants with 13 percent of their energy consumption.
But the biofuel project is not uncontroversial.
“[It] is not a good idea, not at all“, says Danish WWF ocean mammal specialist Anne-Marie Bjerg who wants to see other sustainable energy projects undertaken instead.
“We know very little about the Greenland shark, which lives in a limited geographic zone, the Arctic,” she said. “We are opposed to the commercial use of marine mammals*, such as the Greenland shark, which is not universal and whose population size is unknown.“
AC Comment:
*The Greenland shark is not a mammal since it does not feed its young milk. Mammals are animals whose females are characterized by the possession of mammary glands. The Greenland shark does however give birth to live young. Just like many other sharks, it is an ovoviviparous species. Much remains unknown of the Greenland shark’s reproduction and life cycle.
A 100 metre by 100 metre* anchor-free zone will be established in Studland Bay in Dorset bay to protect the largest seahorse breeding colony in the United Kingdom. To prevent boaters from accidently anchoring within the zone, it will be marked out by six large buoys fitted with flags on top.
“There might be the odd individual who out of spite or grievance will chose to go on there but it will be well marked so if anyone does it will be intentional”, says Natural England maritime advisor Richard Caldow.
The area will be patrolled by wardens and a map of boating activity will be constructed based on their observations during the busy summer season. Marine experts will then compare data from the anchor-free zone to a control zone where boats can anchor.
“I’m not interested in the names of boats”, Caldow says. “I want to know how many there are and where they are going, particularly the level of boating in the voluntary no anchor zone which will hopefully be none.”

The Netherlands now join Norway in the effort to save the European eel Anguilla anguilla from extinction.
Yesterday, the Dutch government announced a two-month long ban on eel fishing that will commence on October 1 this year, followed from 2010 with a yearly three-month prohibition from September. In 2012, the new regulation will be reviewed and its effectiveness assessed.
“I realise this is a very big sacrifice for eel fishers, but ultimately it is also in the interests of the industry that eel numbers are allowed to recover,” Agriculture and Environment Minister Gerda Verburg said in a statement.
Before the regulation can be put into action it will however require the approval of the European Commission. The commission has already rejected a Dutch proposal to enlist the aid of eel fishermen to help boost the eel population by releasing 157 tons of mature, caught eel close to the species spawning waters in the Sargasso Sea.
“The (initial) plan would have offered guarantees for the recovery of the eel population,” the professional fishers’ federation Combinatie van Beroepsvissers said in a statement, describing the new measure as “incomprehensible, unreasonable and unacceptable”.
Eel is a delicacy in the Netherlands and roughly one thousand tons of eel are caught in Dutch waters every year. The Dutch government have designated 700,000 Euros (989,800 USD) to aid the estimated 240 small fishing businesses affected by the eel ban.
Significant areas of coastal wetlands have been restored and enhanced in Port Arthur, Texas. The largest restoration took place in the Lower Neches Wildlife Management Area near the Gulf of Mexico where historic water flow has been brought back into roughly 1,300 acres of wetland.
The other main restoration site is located within the J.D. Murphree Wildlife Management Area where approximately 1,500 acres of coastal emergent marsh plant communities have been restored to historical conditions through the installation of berms and other water control structures.
Almost 90 acres of estuarine intertidal marsh and over 30 acres of coastal wet prairie have also been established by NOAA in conjunction with the U.S. Fish and Wildlife Service, the Texas Commission on Environmental Quality, the Texas Parks and Wildlife Department, the Texas General Land Office, and the Chevron Corporation.
“Coastal wetlands are extremely valuable habitats that provide numerous services for both humans and the environment,” said John H. Dunnigan, assistant administrator for NOAA’s National Ocean Service. “The wetlands restored through this cooperative project will help improve water quality and provide a buffer as tropical storms and hurricanes move onshore.”
The restored wetlands are a way for Chevron to compensate the public for the injury caused by the Clark Chevron refinery in Port Arthur. The refinery, which commenced production in 1902, caused substantial injury to natural areas and waterways inside and adjacent to the processing plant by releasing hazardous substances into the environment.
“These completed projects will not only provide habitat benefits to the fish and wildlife of the region, but will also enhance public use and outdoor recreation opportunities,” said Wildlife Management Area manager Jim Sutherlin.
The restoration is a part of NOAA’s Damage Assessment, Remediation and Restoration Program. Through this program, NOAA works with industry, agencies and communities to restore environments harmed by oil spills, hazardous substance releases and ship groundings. Last year, the program settled nearly 200 natural resource damage assessment cases, generating almost $450 million for restoration projects.
