Officers from the Rare Sea Animal Division of the Phuket Marine Biological Center (PMBC) have revealed today (October 17) that the dead dolphin found on Kamala Beach washed up ashore yesterday was a young Fraser’s Dolphin (Lagenodelphis hosei), which is rare in the Andaman Sea. The body is 2 metres long and weighs approximately 70 kilograms.

The body was still fresh when people found it with round wounds on the left side of its body that looks like a bite marks with some scratches.

The team from the PMBC is still checking on the dolphin body to determine the exact cause of the death.

Philippines: Cause of stranded Dolphin’s death in Surigao investigated
By Roel Catoto, 27th January 2017;

Experts have started an investigation on what caused the death of the Dolphin which was stranded Thursday morning in Surigao City.

The Dolphin suffered a wound above its flukes and died Thursday after hours of efforts to resuscitate it.

Dr. Leona Nortega, a veterinarian at the Bureau of Fisheries and Aquatic Resources in Caraga Region told MindaNews Friday via text message that they have made a necropsy on the mammal.

“We collected some samples for laboratory analysis, we will forward the samples to the central office for histopathology,” she said.

Norteg identified the distressed mammal as a Fraser’s Dolphin (Lagenodelphis hosei), not a Bottlenose Dolphin (Tursiops sp.) as reported Thursday.

Jordan Mendoza and three companions found the Dolphin as it was struggling in knee-deep waters off the sandy beach between sitios Panumbuyon and Panubigon in Barangay Lipata around 5:30 a.m. yesterday. It had a wound on the upper rear part of its body near its tail flukes.

The four, who were gathering shells then, immediately contacted authorities for help.

Chief Insp. Joel V. Liong, of the Surigao City Police Station, measured the Dolphin at 7 feet and 1 inch long, a body circumference of 43 inches and width of 13.5 inches at its widest part.

He said the five-inch wide wound was being swarmed by sand fleas locally known as “bukto.”

Rollie Dizon, a resident of Panubigon who were among the first few who responded to the call for help, said the Dolphin looked frail and kept on vomiting blood.

Some Surigaonons felt sad over the death of the mammal.

Enna Batalzar, a college student, said there should have been a facility and competent personnel who could handle stranded sea animals.

Megan Villasor, a resident of Barangay Washington, said she cried upon seeing the dead Dolphin.

AA Yaptinchay, director of Marine Wildlife Watch of the Philippines, a nongovernment organization advocating awareness on the conservation and protection of marine wildlife in the country told MindaNews that dolphins are among the many sea creatures that have been affected by marine environmental destruction and pollution.

“There are potentially more than 30 marine mammals in the Philippins. However, populations of Dolphins, Whales and the Dugong (Dugong dugon) have declined due to threats such as poaching, bycatch, pollution, and habitat destruction, among others. Moreover, a lot of the marine mammal stranding seem to be human-induced,” MWWP said.

“If humans are the cause of such threats and stranding incidents, humans could also be part of the solution. The Aquatic Marine Wildlife Rescue and Response Manual on Marine Mammals will benefit people working in coastal resource management programs, marine protected areas (MPA), and MPA networks by helping them rescue and release marine mammals back in the wild where they can continue to make significant contributions to the health of the marine ecosystem,” the group said.

Yaptinchay added more and more threats are present in Philippine seas, affecting already dwindling populations of marine wildlife. It is expected that vulnerable species will be affected by threats such as trash, habitat degradation and increasing boat traffic.

Incidents such as Dolphin stranding are expected to occur more often, he said.

“These protected species need to be handled properly in terms of the response such as rescue, data collection, crowd control and awareness raising. Procedures for the response to marine mammals, marine turtles, and sharks and rays can be found in manuals published by Marine Wildlife Watch of the Philippines with the Department of Agriculture and the DENR. All manuals are free to download from the MWWP website,” he said.

The response manual to marine mammal incidents can be accessed at http://mwwphilippines.org/2015/04/14/philippine-aquatic-wildlife-rescue-and-response-manual-to-marine-mammal-incidents/.

Philippines: Rescued wounded Dolphin in Surigao City dies
By Roel Catoto, 26th January 2017;

The wounded Bottlenose Fraser’s Dolphin (Lagenodelphis hosei) rescued in the shallow waters of a coastal village here earlier today died around 4:30 p.m.

This was confirmed by Pinky Amarille of the City Quick Action Response Team and Racquel Curtis, barangay captain of Lipata where the Dolphin was found.

Necropsy was reportedly conducted on the Dolphin, which was then buried at the shoreline of Sitio Panubigon in Lipata.

The Fraser’s Dolphin was found by Jordan Mendoza Abapo and three companions as it was thrashing in knee-deep waters off the sandy beach between sitio Panumbuyon and Panubigon in Barangay Lipata around 5:30 a.m. The shell gatherers immediately contacted authorities for help.

It had a wound on the upper rear part of its body near its tail flukes.

“It was a pitiful sight, the dolphin Dolphin to keep alive. We immediately tried to rescue it and called the attention of the authorities,” Abapo said.

Abapo said the Dolphin was cooperative. “We told him that we will help him and he responded with his sounds,” he said.

Chief Insp. Joel V. Liong, of the Surigao City Police Station, measured the Dolphin at 7 feet and 1 inch long, a body circumference of 43 inches and width of 13.5 inches at its widest part.

He said the five-inch wide wound was being swarmed by sand flea locally known as “bukto.”

“The wound is old and seems to be healing,” Liong said.

The Surigao City Quick Action Response Team stayed by the Dolphin’s side to nurse it back to health, but to no avail.

Rollie Dizon, a resident of Panubigon who were among the first few who responded to the call for help, said the Dolphin looked frail and kept on vomiting blood.

“It has a few scratches on his face and body. I hope it survives,” he said then.

Dr. Leona Nortega, a veterinarian of Bureau of Fisheries and Aquatic Resources in Caraga Region based in Surigao City, advised those helping the mammal to keep its blowhole above the water and for people around it to stay quiet.

She was planning to look for an inflatable pool to nurse the Dolphin there because the water was choppy and only aggravated the Dolphin’s stress.

Had the Dolphin survived and regained its health, it would have been eventually released back to the sea. “That’s the procedure,” Nortega said.

Philippines: Ilocos region top PH hot spot for sea mammal stranding
2015 was the worst year so far, with 112 trapped, according to marine biology expert
By Yolanda Sotelo, 11th October 2016;

At dawn on Oct. 6, a Melon-headed Whale (Peponocephala electra) died right after it was taken from intensive care in a facility in Alaminos City. Hours later, a weak Rough-toothed Dolphin (Steno bredanensis) (Actually a Spinner Dolphin) (Stenella longirostris) was found beached off Santo Domingo town in Ilocos Sur province.

The two incidents occurred on the first day of a national symposium on marine mammals here, as if to emphasize the need to enhance sea environment protection to shield these animals from harm.

The Ilocos region is a hot spot in marine mammal stranding, topping all regions in the last 11 years. A total of 692 stranding incidents have been recorded since 2005, most involving Spinner Dolphins (Stenella longirostris).

Worst year

Last year was the worst so far for animal stranding, with 112 marine mammals trapped or stranded, said Dr. Lemuel Aragones, president of the Philippine Marine Mammal Stranding Network (PMMSN).

There are several reasons marine mammals go to the beach. A 2010 study made by Aragones shows that sudden explosions from dynamite fishing give sea animals “acoustic trauma.”

Sea mammals, like Whales, navigate by sending out sound pulses to find prey and determine their surroundings. When they lose their hearing, they lose their way, Aragones said.

Some animals suffer injuries because of fishing activities. Dolphins have been tangled in fishing nets or gears. Biotoxins and human interaction are also cited as reasons for the stranding.

But the Philippines also has a high rate of live stranding, a reference to sea animals who survive their ordeal at the shore.

Records show 65 percent of beached marine mammals were alive. Of the 692 stranded sea mammals in 11 years, 418 lived. A total of 187 survivors were released back to the sea after receiving supportive care.

“Globally, two or three sea animals are dead when they get to shore,” Aragones said.

Dramatic decline

This year, stranding cases have slid down dramatically, with only 51 beached sea animals recorded as of Oct 6.

Thirteen of these animals were found or treated in the Ilocos region.

The PMMSN said it has a 27 percent success rate in the rehabilitation of stranded marine mammals. The group has no funding, Aragones said, and is dependent on member agencies to subsidize projects to save sea animals.

The group said all regions should have a speed boat that would serve as an animal ambulance that could carry 3-meter long Dolphins and Whales. The Ilocos region has such an ambulance, which can be filled with water and is equipped with a stretcher.

Philippines: Marine group says infection killed Dolphin in Jagna

By Rey Anthony H. Chiu, 27th January 2016;

New findings from a marine group have shed more light on the details surrounding the dead dolphin that washed ashore earlier in Pangdan, Jagna.

According to necropsy reports published on Balyena.org and shared to the Marine Wildlife Watch of the Philippines (MWWP), the Dolphin was a female Fraser’s Dolphin (Lagenodelphis hosei) and not a Bottlenose Dolphin (Tursiops sp.) as earlier reported.

Police and municipal fisheries and aquatic resources authorities earlier erroneously identified the Dolphin as a Bottlenose, measuring an overall length of 2.2 meters and a girth of 37 centimeters.

It had inflicted wounds on its body, more prominent of them has been an identified Cookiecutter Shark bite about five inches from its dorsal fin.

While observers believed the abrasions on the left side of the animal could have caused the death, Balyena.org in their necropsy report stated that the animal had a severe infection of roundworms (nematodes) in its stomach and tapeworms (cestodes) in its blubber and muscles.

“The parasitic infection caused ulcerations in the stomach and most likely led to blood loss and eventually to perforation and peritonitis,” the report which was shared by MWWP showed.

Balyena.org, a non-profit non stock organization conducting Dolphins and Whale research in the Philippines, also added that the two Cookiecutter Shark bites were not the cause of death.

Contrary to what most people think, these oval bites are not fatal.

Cookiecutter Shark bites on cetaceans are fairly common, Balyena.org, in a separate post on their Facebook account, shared.

These sharks, Isistius brasiliensis, or the Cigar Shark, are a member of the Family Dalatiidae or “Sleeper Shark” family.

It is named after the cookie-shaped wounds that it leaves on the bodies of larger fish and marine mammals.

These are also known as the Cigar Shark because of its dark brown and long, cylindrical body shape. It lives in the deep-waters of warmer areas worldwide. Because it emits a greenish glow, it is also known as the Luminous Shark.

The Cookiecutter Shark is considered a “facultative ectoparasite which means it feeds on the flesh of other species causing them harm but not death and it is not dependent on these species for survival.”

The Fraser’s Dolphin that stranded in Pangdan is the second which Balyena.org found there.
