Philippines: Virus strikes Bulacan pond, kills 101,383 Tilapia – report

By Jasper Y. Arcalas, 7th December 2017;

The lethal Tilapia Lake Virus (TiLV) has arrived in the Philippines, killing 101,383 Tilapia (likely Nile Tilapia) (Oreochromis niloticus) in a lone Bulacan-based pond in June, the Department of Agriculture (DA) said.

In a notification submitted to the World Organisation for Animal Health (OIE), Agriculture Assistant Secretary for Livestock Enrico P. Garzon said TiLV killed 101,363 Tilapia out of the 300,000 susceptible population in a Bulacan-based pond, representing a 33.78-percent mortality rate.

Garzon added the outbreak was confirmed last June 29 and has already been resolved by the DA on September 15.

“An unexplained daily mortality of Tilapia fingerlings was observed in the nursery pond of a private farm after stocking on May 16, 2017. Elevated mortality after 15 days reached approximately 25 percent. Affected fish showed distended abdomen and bulging of the eyes,” he said in the notification dated November 23.

Garzon said on May 31, the DA collected samples from the affected farm and were submitted to the Fisheries Biotechnology Center (FBC) in Muñoz, Nueva Ecija.

“Semi-nested RT-PCR exhibited positive results using reported Tilapia Lake Virus [TiLV] primers. Other samples submitted to National Fisheries Laboratory- Fish Health of the Bureau of Fisheries and Aquatic Resources also showed positive results by insulated isothermal PCR [iiPCR],” he said.

The DA official added the laboratory results indicated that the “amplified 3 segment of the viral ENE [expression and nuclear retention element] has 94 to 95 percent nucleotide similarity to Israel TiLV strain.”

Garzon said the movement of fingerlings from the affected pond has been restricted and monitored. He added that the results of the last two samplings showed negative for TiLV.

On May 26 the Food and Agriculture Organization (FAO) of the United Nations warned countries of TiLV as it is considered a “lethal threat” to food security.

“The outbreak should be treated with concern and countries importing Tilapia should take appropriate risk-management measures—intensifying diagnostics testing, enforcing health certificates, deploying quarantine measures and developing contingency plans,” the FAO said.

“Tilapia-producing countries need to be vigilant, and should follow aquatic animal-health code protocols of the World Organisation for Animal Health when trading Tilapia. They should initiate an active surveillance program to determine the presence or absence of TiLV, the geographic extent of the infection and identify risk factors that may help contain it,” the FAO added.

The FAO said the TiLV poses no public health concern, but could decimate infected populations. The TiLV has been reported in at least five countries in three continents: Colombia, Ecuador, Egypt, Israel and Thailand, according to the FAO.

“Tilapia are the second most important aquaculture species in volume terms, providing food, jobs and domestic and export earnings for millions of people, including many smallholders,” it said.

“In 2015 world Tilapia production, from both aquaculture and capture, amounted to 6.4 million tons, with an estimated value of $9.8 billion, and worldwide trade was valued at $1.8 billion,” the FAO added.

Indonesia: Authorities on alert after 2 Elephants found dead in Aceh

17th October 2015;

Local authorities and law enforcers are investigating the recent death of two Sumatran Elephants (Elephas maximus sumatranus) in Aceh Jaya regency, Aceh, after their preliminary investigation suggested that the endangered animals died from poisoning.

Aceh Natural Resources Conservation Agency (BKSDA) head Genman Suhefti Hasibuan said the agency’s examination team had found blood flowing from the mouth and anus of the two female Elephants, which were found dead on Wednesday by residents in Panggong subdistrict, Krueng Sabee district.

“These are strong indications that the Elephants have died because of poisoning,” Genman said on Thursday as quoted by

The agency’s team, which consists of a veterinarian, mahouts and forest rangers, has also collected samples from the animals’ organs.

“The samples will be sent to the National Police’s forensic laboratory for follow-up examinations and legal purposes,” Genman said, adding that the team had not found any wounds on the Elephants.

The bodies of the two Elephants, which were 15 and 2 years of age, were lying some 10 meters apart from one another.

With the discovery of these latest two cases, the agency has recorded five deaths this year of Sumatran Elephants that died in suspicious circumstances.

The agency, Genman added, had reported the case to local police for further investigation.

Wildlife Conservation Society (WCS) Indonesia recently revealed that the Elephant population in Sumatra continued to decrease over the past decade, mainly because of illegal hunting, particularly in Riau, Aceh and North Sumatra.

WCS said the population of Sumatran Elephants was currently no larger than 1,000 animals, or 69 percent lower than 25 years ago.

The decrease in the population of Sumatran Elephants has caused the International Union for Conservation of Nature (IUCN) to list the species as Endangered.

Last month, law enforcers in Lampung launched an investigation into the killing of Yongki, a tame Sumatran Elephant that was found dead at the South Bukit Barisan National Park (TNBBS).

The 35-year-old male Elephant had been found with severe wounds at the base of his missing two tusks.

TNBBS head Timbul Batubara said Yongki’s body had been discovered just 300 meters behind his patrol camp in Pemerihan, West Pesisir regency, which is situated some 120 kilometers northwest of the provincial capital of Bandar Lampung.

Speaking to reporters on Thursday, Lampung Police special criminal investigation directorate head Sr. Comr. Dicky Patria Negara said the police had so far interrogated 20 witnesses in the case.

The police, he said, believed that Yongki’s tusks had been shipped out of the province to the illegal market overseas.

“Our focus now is on looking for the suspects. It is clear that there are more than two people [involved in the murder],” he was quoted as saying by Antara news agency.

Apart from the struggle to survive illegal poaching, Sumatran Elephants have seen their continued survival at risk, with many babies dying over the past three years from Elephant endotheliotropic herpesvirus (EEHV).

The North Sumatra-based Veterinary Society for Sumatran Wildlife Conservation (VESSWIC), for example, reported that the EEHV virus had killed five young Elephants in Way Kambas, Lampung, in 2012 and four others between October last year and February. Another calf died in Aceh in February.

“While adult Elephants can survive EEHV attacks, many calves have died [because of EEHV]. The virus is threatening their population,” Muhammad Wahyu of VESSWIC recently said.

EEHV-infected Elephants, according to Wahyu, suffer from lower immunity, swollen faces and blue tongues.

Indonesia: Virus kills four young elephants in Lampung

4th February 2015;

A state of emergency has been declared at the Elephant Conservation Center (PKG) in Way Kambas National Park in Lampung following to the death of four young elephants over the past three months.

The four juveniles, aged between three and eight years old, died after being infected by the elephant endotheliotropic herpesvirus.

PKG head Antonius Fevri said the state of emergency was declared after the deadly virus claimed a quarter, or four of 16 young elephants in the breeding area. He said this was the first outbreak of the virus at the center.

“The virus attack is very fast and the incident lasts less than 24 hours. The first three young elephants who died in November 2014 showed symptoms of the illness in the morning and were dead by the afternoon,” he said as quoted by

“The infected elephants [all] show similar symptoms. Our employees found them in weak condition with their tongues turned blue and a significant drop in body temperature, he said.

Antonius said he suspected the virus had been transferred by adult elephants to younger elephants but that the juveniles were unable to fight the virus because of their lower immunity levels.

He said the state of emergency would last for 20 days and that a medical team would check up on the remaining juveniles twice a day, who would be segregated from the adult elephats.

Lots of dead farm fishes washed up at Lim Chu Kang
By Ria Tan, 17th October 2014;

This morning I saw many freshly dead fishes washed up at Lim Chu Kang jetty. The dead fishes look like those raised by fish farms.

What killed these fishes? Were these dead fishes deliberately dumped by the fish farms instead of being properly disposed?

All along the shore, there is a line of dead fishes at today’s low water mark. With more fishes floating in the water. A lot more dead fishes are floating in the water between the shore and the fish farms.

There is a line of dead fishes at the most recent mid-tide mark. The fishes here look quite freshly dead.

At the high water mark, the dead fishes here are starting to decompose. Have dead fishes been washing up for a while? Smaller quantities in the days before?

One fish was crawling with live maggots. Quite creepy! I didn’t see any dead wild fishes.

It appears that the Milkfish (Chanos chanos) being raised by the fish farms off Lim Chu Kang are dying in large numbers.

Any dead fishes on Singapore’s northern shores?
By Ria Tan, 16th October 2014;

Two farms in Lim Chu Kang lost about 60 tonnes of fish to a marine bacteria, Vibrio, said Singapore Marine Aquaculture Cooperative Chairman Phillip Lim to Channel NewsAsia. His own farm has also been affected. “I started with 8,000 fish. I’m only left with 200 to 300-plus fish,” he said.

Is Vibrio dangerous to humans? Did any of these dead fishes wash up on Singapore’s northern shores? We had a quick look last night and today.

Did any of these dead fishes wash up at Lim Chu Kang?

I headed for Lim Chu Kang jetty as soon as I heard the news. The road really does end abruptly here so it’s important to watch out, in the dark!

I saw a handful of dead fishes along the short 10m stretch that I checked of the shore. Some of the fishes looked recently dead. Others looked like they were dead for a day or so, eye missing. These look similar to the hundreds of dead fishes that floated up at Lim Chu Kang and Sungei Buloh last year.

Marine bacteria detected in fish samples
A large number of fish in 44 farms have died due to the infection, causing frustration among fish farmers. Humans can get infected by consuming undercooked seafood or exposing an open wound to sea water.
15th October 2014;

A marine bacteria, Vibrio, has been detected in fish samples taken from Singapore’s coastal fish farms.

While Vibrio is found naturally in tropical marine environments, humans can get infected by consuming undercooked seafood or exposing an open wound to sea water. Diarrhoea, vomiting and fever are some symptoms of the infection.

Experts say warm weather and rising sea surface temperatures have led to the rapid growth of marine micro-organisms, which release toxins that kill the fish. A large number of fish in 44 farms have died due to the infection, causing frustration among fish farmers.

Singapore Marine Aquaculture Cooperative Chairman Phillip Lim said two farms in Lim Chu Kang lost about 60 tonnes of fish to Vibrio, and his own farm has also been affected. “I started with 8,000 fish. I’m only left with 200 to 300-plus fish,” he said. The infection was discovered when they sent samples to the Agri-Food and Veterinary Authority of Singapore for examination.

“For us, as farmers, we don’t have the equipment, so we need more professional help on that, to advise us what to do about all this. Because Vibrio can also infect humans, so it is quite dangerous.” Mr Lim said stress might have killed the fish as well.

While dead fish are disposed of, those still alive are sold at local markets. The public is urged to ensure the fish is fully cooked, before consuming them.

The fish in the photo is possibly a young White Tamban (Sardinella albella), which is not raised in farms. A rather weird choice of species to illustrate an article about fishes in farms dying from disease.

Thailand: Signs of foot-and-mouth disease found in some Gaur carcasses

By Janjira Pongrai, 8th March 2014;

Most recent tests show that four of the 24 Gaurs (Bos gaurus) that died mysteriously in December in Kui Buri National Park in Prachuap Khiri Khan had foot-and-mouth disease, Nipon Chotibal, acting chief of the National Parks, Wildlife and Plant Conservation Department, said yesterday.

A panel of academics investigating the deaths will discuss the results today and look for ways to prevent further outbreaks. Mahidol University’s Faculty of Veterinary Science conducted the lab tests and will officially announce the results on Tuesday.

Nipon said Gaurs are more sensitive to the disease compared to other hoofed animals, citing previous Gaur deaths in India from the same disease. It is suspected that the disease spread from other animals in the area, adding that foot-and-mouth disease had been detected in the province and in Ratchaburi earlier this year.

Nipon added that though the situation was under control to a certain degree, Kui Buri Park would remain closed indefinitely as a precaution. Tuenjai Nuchdamrong, director of the Wildlife Conservation Office, said this was the first time that traces of the disease has been found in wild Gaurs in Thailand, adding that agencies would find ways to protect the remaining 100 Gaur in Kui Buri and in Khao Yai National Park in Nakhon Ratchasima.

Since it is believed that the foot-and-mouth disease might have been transmitted from a wild animal that was returned to nature without the knowledge of the authorities, she said the public and relevant agencies would be warned to no longer release animals without proper screening.

Initial tests showed 17 of Gaur carcasses had traces of a nitrate compound, while nine had the bacteria Clostridium novyi. However, the cause of the deaths was not determined.
