Philippines: Dead Dolphin found floating off Masbate
By Suzene Cajegas, 3rd May 2017;

A lifeless Dolphin, locally called “lumba-lumba”, was found floating on sea near the shores of Dimasalang town in Masbate province early Tuesday, a police report said Wednesday.

The Dimasalang police received a call around 5:30 a.m. from an employee of the town’s local government unit regarding the two-meter long dead Dolphin that was found in Barangay (village) Canomay by Junal Alvarez, a resident in the village.

Municipal agriculturist Irish Cabrera and police recovered the dead Dolphin to collect information on its age, sex and variety of the species. The town officers have already coordinated with the Bureau of Fisheries and Aquatic Resources (BFAR) Masbate to submit information on the recovery of the Dolphin.

Philippines: Parasites, changing temperature cause Dolphin deaths in Bicol
‘Parasites or their eggs may be carried through human or animal feces dumped in the sea that fish and even the marine mammals may feed on,’ says Dr Evelyn Saberon of BFAR
By Rhaydz B. Barcia, 11th March 2017;

Parasites from sea creatures that can affect humans killed two Dolphins in Bicol, the Bureau of Fisheries and Aquatic Resources (BFAR) in Bicol reported here.

Dr Evelyn Saberon, BFAR veterinarian who conducted the necropsy of two stranded Dolphins, said she found thread-like worms in the stomach of the Dolphins found in Libon, Albay and Mercedes in Camarines Norte.

The Contracaecum parasite can also be found in humans.

Nonie Enolva, BFAR-Bicol Marine Fisheries Resources Management Section chief and spokesperson, said that a stranded adult female Spinner Dolphin (Stenella longirostris), measuring 1.6 meters in length and weighing 43 kilograms, was brought in for necropsy at the Regional Fisheries Health Management and Diagnostics Laboratory of the BFAR regional office on March 4, 2017.

“The carcass was brought in by BFAR’s Fisheries Emergency Stranding Response Team personnel who were deployed immediately to the area after residents reported the Dolphin stranding on the same day,” Enolva said.

Spinner Dolphins are well known for acrobatic acts as they spin their bodies when they emerge from the water.

Enolva said this is the 3rd reported “marine mammal stranding” in Bicol that has resulted in death this year. This came less than a week after another Dolphin died in Mercedes despite rescue and release efforts last February 28, 2017.

After conducting a necropsy, Saberon found that the mammal had enteritis and its stomach and bladder were empty. This suggests that the animal had no food intake in the past few days prior to its death.

Petechial hemorrhaging (small red spots) was also detected in the animal’s intestines.

Contracaecum parasites – though not as severe as in the first Dolphin – also contributed to its death.

“The parasites were still alive. These parasites weakened the animal until its death,” Saberon said.

Temperature changes

Sudden changes in temperature also contributed to the stress of the Dolphin.

“The sudden changes in temperature contributed to the stress of the animal and that is why Dolphin stranding is more common in this part of the year,” Saberon added.

Saberon explained that some parasites found in marine mammals are zoonotic or can infest more than one species.

“Parasites or their eggs may be carried through human or animal feces dumped in the sea [that] fish and even the marine mammals may feed on,” she said.

Blood and tissue samples were taken from the animal to the Marine Mammal Research Stranding Laboratory in UP Diliman for their Project LepTox.

Project LepTox is a research effort to investigate the occurrence of leptospirosis and toxoplasmosis, a disease caused by a certain parasite that also affects humans.

Megamouth Shark

It will be recalled that in January 2015, a male Megamouth Shark was also stranded and found in the coast of Pioduran, Albay.

The Shark was captured by 39-year-old Edgar Chavez – a fisherman from Barangay Marigondon in Pioduran, Albay – and his companions.

Enolva said the Megamouth Shark (scientific name: Megachasma pelagios) is also the 3rd biggest filter-feeding Shark. A Megamouth Shark is among the rarest species in the world, weighing one ton with a life span of 100 years.

The Megamouth Shark can reach a maximum length of 17 feet and resides in great depths or deep water. It rises to the surface at night to feed on plankton.

Enolva said the Megamouth Shark is not edible as it contains poisonous toxins – it can have bio-accumulation of heavy metals. Once eaten by humans, it could cause infertility and even cancer.

The Megamouth Shark underwent taxidermy (all organs of the specimen were removed and its skin soaked in formalin) and stuffing for museum display.

The Shark, through taxidermy, was preserved and displayed at the Albay Parks and Wildlife for scientific study, following the order of then Albay governor and now 2nd District Representative Joey Sarte Salceda.

In July 2010, a giant Sperm Whale (Physeter macrocephalus) that had started to decompose, was also washed ashore in the coastal town of Rapu-Rapu, Albay.

Philippines: Lake Buhi in state of calamity due to fish kill
By Erwin Colcol, 1st December 2016;

Lake Buhi in Camarines Sur has been declared a state of calamity due to massive fish kill, a television report said.

Citing local officials, GMA News’ Unang Balita reported Thursday morning that up to 1,000 fish cage owners have been affected by the fish kill.

Authorities said fish kill usually occurs after continuous rain for several days, adding that chemicals from fish feed also cause deaths of fish.

They said an estimated P500,000 in local revenue has been lost because of the fish kill.

Buhi government officials had met with Bureau of Fisheries and Aquatic Resources experts and civilian volunteers to discuss ways to address the problem.

Philippines: Chemicals in Tilapia feeds, changes in temperature cause Lake Buhi fish kill; town in state of calamity
By Ruel Saldico, 25th November 2016;

A state of calamity was declared in this municipality because of the occurrence of a fish kill over the past few weeks, delivering a big blow to almost a thousand fish cage owners and operators. The initial estimate of damage is at least half a million pesos.

Mayor Margie Aguinillo said that while it is the Tilapia (Oreochromis sp.) species devastated by the occurrence, what is disturbing is that even the smallest fish species endemic to the lake, the Philippine Goby (Pandaka pygmaea actually Mistichthys luzonensis) or “sinarapan,” have also been wiped out.

The Bureau of Fisheries and Aquatic Resources (BFAR), however, said the fish species still exists, but only in lakelets around Lake Buhi and not in its massive expanse which is prone to bacteria, especially during the rainy season.

Fish kills have been a common occurrence in the lake in the months of September-November, said Aguinillo, and this is due to several factors such as the sudden change of temperature in the lake and an increase in bacteria.

Last Thursday, she met with civilian volunteers, the Philippine Coast Guard (PCG), and the BFAR; and concluded that water contamination in Lake Buhi could also be traced to the chemicals introduced in the lake in the form of feeds given to Tilapia in fish cages.

One of the immediate solutions agreed upon was to establish a detachment of the Coast Guard Auxiliary Unit here that will ensure no more additional fish pens will be built in the lake to avoid overcrowding and that existing fish cage operators will refrain from using chemicals to feed their Tilapia.

Philippines: Whales and dolphins have own cemetery too

By Frank Peñones Jr., 25th October 2016;

Whales and Dolphins here are assigned their own graveyard too.

Dead sea mammals, which are collectively called cetaceans, have been allotted a burial place at the Bureau of Fisheries and Aquatic Resources (BFAR) Regional Freshwater Fisheries Center (RFFC) in Barangay Fabrica in Bula, Camarines Sur.

“We have so far a dozen cases of dead Whales and Dolphins found or stranded in the beaches of Bicol, so we thought of burying them properly, and that’s how the Cetacean Cemetery came to be,” Noni Enolva, spokesperson for BFAR, in Bicol said.

She added that a Dwarf Sperm Whale (Kogia sima) found in Ragay in April 2014 was the first cetacean to have been buried in the cemetery; while the latest were two Spinner Dolphins (Stenella longirostris) found in Tinambac town in July this year.

Cetaceans are a widely distributed family of finned and carnivorous aquatic mammals, which include Whales, Dolphins and Porpoises.

Enolva said that when these dead mammals are found, they are brought to the RFFC for necropsy to determine the probable cause of their death by members of the Fisheries Regional Emergency Stranding Responding Team.

Some causes of death include ingestion of plastic and other solid wastes and acoustic trauma, a sensory hearing loss caused by dynamite explosions or seafloor drilling.

“They become deaf due to these explosions and eventually lose their equilibrium, so they drown. A deaf whale is a dead whale,” Enolva said.
