Filipino Fishermen Having a Blast, Scaring Whales, Destroying Coral

, , , ...

by Underwatertimes.com News Service

Babuyan Islands, The Philippines (Mar 19, 2006 19:04 EST) FISHERMEN in the once tranquil Babuyan Islands in Cagayan province are literally having a blast.

Local fishermen, citing poor catch in recent months, have resorted to dynamite blasting to salvage metal from shipwrecks surrounding the islands, according to the World Wildlife Fund (WWF)-Philippines.

It is said to be the newest and most environmentally damaging source of livelihood in the islands, said the WWF, which conducts an annual on-site monitoring of the Babuyan Islands for its Humpback Whale Research and Development Project.

The blasting is scaring away the Pacific humpback whales that come to the Philippines to breed this time of the year, it said.

The dynamite blasts are also inevitably destroying the coral reefs in the Camiguin Island, where the blasts have been monitored.

The WWF records an average of 100 sightings in the Babuyan Islands annually but fears that this would be reduced due to the dynamite blasts.

"We will continue to monitor the whales to see if the blasting has a direct impact on the whales ... although definitely there must be permanent damage to the coral reefs in the area," WWF consultant Jomarie Acebes said in a phone interview.

Located about 50 km north of the Luzon mainland, the Babuyan Islands has the highest known cetacean species diversity in the Philippines, hosting 14 of the 25 known cetacean species in the world including the humpback whale, sperm whale and bottle-nosed dolphin.

The WWF team that arrived in Camiguin Island north of Cagayan province on Feb. 17 has recorded up to six blasts per hour almost everyday. On March 18, just days after the Calayan police arrived in Camiguin, four blasts were recorded again.

"The blasts are really loud. You can hear it even up to eight kilometers from the shore. That's very loud considering that the dynamites explode under water," Acebes said.

The locals themselves have admitted that those who go out for blasting use about a gallon of dynamite for every trip, she said. They dive to plant the dynamites in the shipwrecks and then recover the steel that comes loose due to the explosion.

The scrap metals are sold in the island for about P4 per kilo. The dealer from the island then sells the scrap in Aparri or Cagayan for about P10 per kilo, Acebes said.

There are at least five known shipwrecks surrounding Camiguin Island, all of which are in the breeding ground of humpback whales that travel to the Babuyan Islands before proceeding to Alaska and Russia to feed.

The shipwrecks, which are more than 20 years old, have become artificial reefs that serve as refuge and breeding ground for fish.

Acebes said the locals have been salvaging metal from the shipwrecks for about two years now, but they used to dive and use acetylene to recover the loose scraps.

The locals have only started to use dynamites these past few months because they wanted to get bigger pieces of metal, she said.

The Cagayan provincial government passed an ordinance in 2003 declaring the humpback whales as protected species within the territorial jurisdiction of the province.

The WWF has written Calayan Mayor Joseph Llopis to inform him of the blasting. The Department of Environment and Natural Resources and the Bureau of Fisheries and Aquatic Resources have also been informed of the illegal activity.

The Calayan police have also visited Camiguin and apprehended the locals for the blasting but the WWF revealed that no police report has been filed in Calayan about the blasts.

Pressures such as illegal hunting and overfishing have threatened the global population of cetaceans. Humpbacks are listed as endangered under the International Union for the Conservation of Nature and the US Endangered Species Act.

Marine Biology Mystery Solved: Function of "Unicorn" Whale's 8-foot Tooth Discovered

Marine Biology Mystery Solved: Function of "Unicorn" Whale's 8-foot Tooth Discovered
Harvard School of Dental Medicine Researcher Announces Findings Today

SAN DIEGO-Dec. 13, 2005-Today, Harvard School of Dental Medicine (HSDM) researcher Martin Nweeia, DMD, DDS, answers a marine science question that has eluded the scientific community for hundreds of years: why does the narwhal, or "unicorn," whale have an 8-foot-long tooth emerging from its head, and what is its function? Nweeia, a clinical instructor in restorative dentistry and biomaterials sciences at HSDM, will be presenting his conclusions at the 16th Biennial Conference on the Biology of Marine Mammals in San Diego.
The narwhal has a tooth, or tusk, which emerges from the left side of the upper jaw and is an evolutionary mystery that defies many of the known principles of mammalian teeth. The toothÕs unique spiral, the degree of its asymmetry to the left side, and its odd distribution among most males and some females are all unique expressions of teeth in mammals. The narwhal is usually 13 to 15 feet in length and weighs between 2,200 and 3,500 pounds. Its natural habitat is the Atlantic portion of the Arctic Ocean, concentrating in the Canadian High Arctic: Baffin Bay, Davis Strait, and northern Hudson Bay. It is also found in less numbers in the Greenland Sea, extending to Svalbard to Severnaya Zemlya off the coast of Russia.
Nweeia has discovered that the narwhal's tooth has hydrodynamic sensor capabilities. Ten million tiny nerve connections tunnel their way from the central nerve of the narwhal tusk to its outer surface. Though seemingly rigid and hard, the tusk is like a membrane with an extremely sensitive surface, capable of detecting changes in water temperature, pressure, and particle gradients. Because these whales can detect particle gradients in water, they are capable of discerning the salinity of the water, which could help them survive in their Arctic ice environment. It also allows the whales to detect water particles characteristic of the fish that constitute their diet. There is no comparison in nature and certainly none more unique in tooth form, expression, and functional adaptation.
"Why would a tusk break the rules of normal development by expressing millions of sensory pathways that connect its nervous system to the frigid arctic environment?" says Nweeia. "Such a finding is startling and indeed surprised all of us who discovered it." Nweeia collaborated on this project with Frederick Eichmiller, DDS, director of the Paffenbarger Research Center at the National Institute of Standards and Technology, and James Mead, PhD, curator of Marine Mammals at the National Museum of Natural History of the Smithsonian Institution.
Nweeia studied the whales during four trips to the Canadian High Arctic. In the past, many theories have been presented to explain the tooth's purpose and function, none of which have been accepted as definitive. One of the most common is that the tooth is used to display aggression between males, who joust with each other for social hierarchy. Another is that the tooth is a secondary sexual characteristic, like a peacock's feathers or a lion's mane.
s Nweeia's findings point to a new direction of scientific investigation. Fewer than 250 papers have been published about the narwhal, and many offer conflicting results. Because of its Arctic habitat and protected status in Canada, the whale is difficult to study. Nweeia has brought together leaders from the fields of marine mammal science, dental medicine, engineering, mathematics, evolutionary biology, anatomy, and histology.
The sensory connections discovered by Nweeia and his colleagues also are capable of tactile ability. Narwhals are known for their "tusking" behavior, when males rub tusks. Because of the tactile sensory ability of the tusk surface, the whales are likely experiencing a unique sensation.
Results from the team's research already has practical applications; studies about the physical makeup of the tusk, which is both strong and flexible, provide insight into ways of improving restorative dental materials. (An 8-foot-long tooth can yield one foot in any direction without breaking). Nweeia also leads the Narwhal Tooth Expeditions and Research Investigation, founded in 2000, which combines scientific experts with Inuit elders, who have collected notes for hundreds of years, to discover the purpose and function of the narwhal tusk.
"Now that we know the sensory capabilities of the tusk, we can design new experiments to describe some of the unique and unexplained behaviors of this elusive and extraordinary whale," said Nweeia.
This work was funded by Harvard School of Dental Medicine; the National Geographic Society; Sunstar Butler; the Smithsonian Institution Center for Arctic Studies; Astro-Med, Inc.; and Fisheries and Oceans, Canada.

After A Long And Storied Life, Keiko Buried In Norway :(

, , , ...

By Kristian Foden-Vencil

PORTLAND, OR 2003-12-15
(Oregon Considered) - Keiko, the killer whale who stared in the blockbuster movie 'Free Willy,' was buried in a low key ceremony in Norway Monday. He died unexpectedly last Friday, of what his handlers believe was the onset of pneumonia.

His death marks the end of a long and somewhat bizarre chapter in marine biology

Scientists believe Keiko was born in 1977, when blockbusters like Close Encounters and Smokey and the Bandit illuminated the silver screen. At the age of two, he was captured near Iceland and put in a local aquarium.

As he grew, he moved -- and was eventually sold for $350,000 to an amusement park in Mexico City. It was there, in a very small tank filled with water much too warm for a killer whale, that Keiko was chosen to star in the movie 'Free Willy.'

Marine biologist Naomi Rose, of the Humane Society, saw him in Mexico and says Keiko proved to be a real survivor -- one of only two male orcas to have lived more than a quarter of a century in captivity.

Naomi Rose: "You know I'm really sad about this. I knew him personally, just like a lot of folks in Oregon did. And this was unexpected, but in one sense it really wasn't. Because captive killer whales, and for all we know wild killer whales, do tend to die unexpectedly in that they don't tend to show a lot of symptoms of illness before they die."

Indeed, as recently as last Wednesday, Keiko had followed his keepers in Norway out to sea for what they called 'an ocean walk.' He appeared lethargic however and by Thursday he'd stopped eating.

Mark Berman, of the Free Willy Keiko Foundation, says he touched millions.

Mark Berman: "When Free Willy came out, and we started the program 10 years ago, we had people who were 6, 7, 8 years old writing to us. So now those people are in their late teens, and they're still writing to us about Keiko and whales, so it's had a tremendous impact on many people to want to save the whales, dolphins and marine eco-system as a whole."

Keiko's story is linked with the Beaver State in several different ways.

First, the movie was shot in Portland and Astoria. Then, the orca was transported to the Oregon Coast Aquarium in Newport for rehabilitation.

Aquarium spokesman, Hugh Dolly, says the people who worked with Keiko are saddened by the news, but they like to think of what they did to help him.

Hugh Dolly: "When he left on September 9th 1998 he had gained over 1000 lbs, he had grown over 8 inches in length, when he arrived here he had several skin lesions, those were nearly all gone. His muscle tone and stamina where greatly improved. So he was very healthy and we're very happy to have played our role in that."

Indeed, the aquarium's yearly attendance record of two and a half million was reached during Keiko's stay. His tank has since been redesigned to feature a shark exhibit in which visitors walk through a 200 foot plexi-glass tunnel.

Keiko left Newport and Oregon for Iceland where he remained for four years. Eventually he struck out on his own traversing the Atlantic in five weeks.

He disappointed biologists, however, when he ended up in Norway and began interacting with humans.

Indeed, not everyone thinks of the $20 million spent on Keiko, as a success story. But Naomi Rose, of the Oregon Humane Society, disagrees.

Naomi Rose: "I think one of the things we learned, which is the essential 'take-home' message of this project, was that taking a long-term captive killer whale like Keiko, and returning him to his natural habitat, can be done. Every step of the way people were being doom sayers, saying he was going to die now, he's going to die now, and every time he didn't and when he got to Norway, he lived a good year and a few months beyond arriving in Norway as well."

Work is already underway for a concert in Portland to celebrate the unusual orca. Theresa Demarest says she'll be there.

She wrote the song 'Keiko's Dream' after visiting him in Newport while undergoing treatment for breast cancer.

Theresa Demarest: "I was one of the folks that, when I went to go see him, he came directly too me, in front of me, eye to eye and we had this eye contact. And then I turned my head to the left and he turned his head to the left. Then I turned my head to the right and he turned his head to the right. It just blew me out of the water and the whole arena area watching this occur. We were just stunned by it."

No word yet on when that concert might be. Details will be posted on the Free Willy Foundation website.

New Species of Living Baleen Whale Discovered

,

UK: November 20, 2003


LONDON - Japanese scientists have identified a new species of living baleen whale after examining the skeletons of several specimens caught in the 1970s.


Shiro Wada and researchers at the National Research Institute of Fisheries Science in Yokohama said the specimens resembled fin whales although they were smaller.

But after examining their DNA, the shape of their skull and the baleen plates they use to filter plankton from the water they were convinced the specimens were a new species.

The comparison "separated them from all known baleen whale species," Wada said in a report published in the science journal Nature yesterday.

The researchers also separated other similar types of baleen whales - Bryde's whale and Eden's whale - into two distinct species.

Baleen whales have no teeth and use the baleen plates that hang down from the roof of their mouths to gather food.

New Scientist magazine described the research as a stunning find and said it reinforces how little is known about the world's fauna, including its greatest mammals.

"We are in the midst of a major rethink about what constitutes a species, and where the boundaries lie between them," the magazine said in its latest issue.
