Philippines: Fish kills reported in Pangasinan and Negros Occidental; bangus prices fall
By John Ted Cordero, 25th May 2016;

Changes in weather pattern have caused fish kills in two municipalities of Pangasinan.

According to a report on News To Go on Wednesday, the fish kills occurred in the municipalities of Anda and Bolinao.

Fish trade in two barangays of Bolinao and Anda were affected by the said fish kill.

Thirty percent of bangus (Milkfish) (Chanos chanos) have died causing the prices to fall at P10 per kilo, the report said.

The municipal agriculturist explained that the fish kills were caused by changing weather.

He added the weather is very hot during morning but rain will fall suddenly in the afternoon.

Meanwhile, a fish kill was also reported in Binalbagan River in the municipality of Isabela, Negros Occidental.

According to the Municipal Agriculture Office of Isabela, various fishes like Tilapia (Oreochromis sp.) and haluan (Common Snakehead) (Channa striata) died after rainfall.

Authorities are looking into sulfur contamination as the cause of the fish kill, the report said.

Ashes and pyroclastic materials from Mt. Kanloan were possibly washed through Binalbagan River.

Authorities advised residents not to eat the dead fishes as these might poison them.

They also took mud and water samples from the river to find out the real cause of the fish kill.

Some of the locations affected include Dewey (on the island of Tagaporo), Pilar and Salud (on Santiago Island), which are barangays in Bolinao, while others, such as Awag (on Cabarruyan Island) and Siapar (on Siapar Island), are barangays in Anda, another municipality in Pangasinan. The victims are Milkfish (Chanos chanos), a species that is raised in fish farms throughout much of the Philippines.

Milkfish (Chanos chanos)
Sungei Buloh Wetland Reserve, 2nd February 2016

This photo of the carcass of a Milkfish was shared by Yap Xinli. I also came across it later that same day and took some photos of my own.

The location of this dead fish, on one of the wooden bridges within Sungei Buloh Wetland Reserve, suggests that it had been picked up and then dropped by another animal, possibly a Bird of Prey or a Feral Dog (Canis lupus familiaris).

Given that Milkfish are raised in some of the fish farms in the waters of the western Straits of Johor, it is difficult to determine whether the Milkfishes found in these waters are of captive or wild origin.

Indonesia: Phytoplankton population explosion caused death of fish in Ancol: Indonesian Institute of Sciences

2nd December 2015;

The mass death of fish, found washed ashore North Jakartas Ancol Dream Land beach, was due to a population boom of the Coscinodiscus species of phytoplankton, noted the Indonesian Institute of Sciences (LIPI).

In a press statement here on Wednesday, the Oceanic Research Center of LIPI said the phytoplankton population had significantly reduced the oxygen content in the water.

According to LIPI, based on tests conducted on the water samples taken from three locations on Ancol beach on Tuesday, the oxygen content in the water was found to be very low at only 0.765 milliliters per liter (ml/L), while the normal oxygen level is about four to five ml/L.

The low content of dissolved oxygen is the cause of the mass death of fish at Ancol beach. Based on the observation, the density of phytoplankton was recorded at one to two million cells per liter of water.

Coscinodiscus spp. is one of the species that is actually not dangerous, but since it has a large number of cells, it absorbs a significant amount of oxygen, thereby resulting in a drop in the levels of dissolved oxygen in the water.

Thousands of dead fish were found washed up along the Ancol beach early on Monday.

The fish species found dead included Milkfish (Chanos chanos), Mullet (F. Mugilidae), and Snapper (F. Lutjanidae).

Indonesia: Thousands of fish found dead in Ancol

1st December 2015;

Thousands of dead fish of various species washed up along Ancol beach in North Jakarta on Monday, allegedly due to toxin contamination from nearby rivers.

“Ancol management reported that it had found many dead fish on its beach early on Monday morning. When we arrived at the scene, there was around a ton of fish washed up on it,” said law enforcement head of Jakarta Water Police division Comr. Edi Guritno.

He added that there were various types of fish, such as Snapper (F. Lutjanidae), Mullet (F. Mugilidae), Grouper (SubF. Epinephelinae) and Milkfish (Chanos chanos).

According to Edi, after the report, the water police immediately took measures to remove the dead fish from the coastline, as well as investigating the cause of their deaths.

He added that the police, in cooperation with Ancol management, had deployed a pickup truck and plastic bags to take the fish from the shore to the Ancol garbage dump, where they would be burned.

Edi said the police had sent samples of the fish and sea water to the Jakarta Maritime, Agriculture and Food Security Agency (KPKP) for scientific examination to confirm the cause of death.

Nonetheless, Edi said that the Ancol management and residents suspected that the fish had died of poisoning from pollutants carried by rivers that flowed into the sea in the Ancol area.

Separately, head of the KPKP’s fisheries division, Lilik Litasari, offered a similar interpretation.

Lilik told reporters that she had met with a number of Ancol management staff and residents and also examined the condition of the water.

Based on her preliminary investigation, she concluded that the waters had been contaminated with hydrogen sulfide (H2S), a colorless poison carried in the mud from the rivers. According to her, the H2S deprived the sea water of oxygen, causing the death of the fish.

According to her, the poisonous mud had possibly flowed to the sea during rain last Friday and Saturday.

“This is a phenomenon that usually occurs early in the rainy season after a long drought. A large volume of water flows from the land to the sea, carrying along sediment that has been deposited in the rivers,” Lilik said.

However, Lilik emphasized that the current theory was only based on the preliminary analysis and that the agency would make a final conclusion after receiving results from the laboratory.

She revealed that Monday’s incident was not the first for Ancol’s management, as it had experienced a similar phenomenon previously, although not with an amount of dead fish as large as this.

Ancol management said that a similar incident occurred three years ago.

According to Pembangunan Jaya Ancol corporate communications manager Rika Lestari, the management had predicted Monday’s incident for over a week before the dead fish were discovered.

“A week ago, our field officers predicted this would occur as they saw foam on the sea water,” Rika said.

She added that in the name of safety the management was currently asking beach visitors not to swim on the beach.

Responding to the issue, an environmental activist from Indonesian Forum for the Environment (Walhi), Mukri Friatna, urged the Jakarta administration to quickly examine the quality of its sea water considering that Monday’s incident was not the first of its kind.

He said that by examining the sea water the administration could identify what substances were in the water and thus discover if the water was polluted because of natural toxins or a result of bad waste management.

“In the end, they [the officials] can decide the best measures to reduce contamination in Jakarta’s seas,” Mukri said.

Philippines: Milkfish entering Dagupan monitored
By Yolanda Sotelo and Gabriel Cardinoza, 1st May 2015;

Officials in this city are monitoring the entry of “bangus” (Milkfish) (Chanos chanos) from aquaculture areas in Anda and Bolinao towns that were hit by fish kill.

Emma Molina, city agriculture officer, said the local government issued a 24-hour alert on trucks delivering bangus to this city.

On Monday, seven trucks were stopped from unloading their shipment of bangus and were sent back to their origin. It was on that day when fish cage operators seemed to have panicked after water in the Kakiputan Channel, the 7-kilometer stretch of body of water shared by Bolinao and Anda, turned chocolate brown.

“Many operators were forced to harvest their stocks and took them here,” Molina said.

Dagupan is a trading center for bangus where fishpond operators unload their harvests to be sold to wholesalers and retailers from other provinces.

Not all areas in Anda and Bolinao, however, were affected by the fish kill, Molina said. Shipments covered by auxiliary invoices will be accepted, she said.

Auxiliary invoices, which are issued by the municipality where the shipment comes from, certify that the areas where the fish were harvested are safe and that the fish are fit for consumption.

Monitoring teams from the agriculture office are accompanied by a sanitary inspector or a city health officer.

On Sunday, at least five trucks of dead bangus were hauled from the Kakiputan Channel, local officials said.

Nestor Batalla, assistant provincial agriculturist, said about 40 of the 200 cages with at least 40,000 bangus each were wiped out by the fish kill.

Bolinao Mayor Arnold Celeste said the fish kill might have been caused by the sudden downpour on Saturday night. “The day was very hot, and then when it suddenly rained, the water temperature changed, sending the bangus gasping for breath and eventually dying,” he said.

The fish kill started in the waters of Pilar and Salud villages on Saturday. The following day, it spread to Barangay Lucero and other parts of Salud, then to parts of Barangay Luciente 2 on Monday.

On Tuesday, three other villages were hit — Catubig, Tara and Luna.

Westly Rosario, chief of the National Integrated Fisheries Technology Development Center in Dagupan City, said a low dissolved oxygen level was noted in the area last week because of the neap tide, a twice-a-month phenomenon where high tide is at its lowest level, preventing water at the channel to freshen up.

On Wednesday, Rosario said fish in the wild, such as mullet (F. Mugilidae), goby (F. Gobiidae), siganid (Rabbitfish) (F. Siganidae), groupers (SubF. Epinephelinae) and shrimps, were found floating in the channel.

The dissolved oxygen level recorded in the area was less than 1 part per million (ppm), or way below the normal 5 ppm.

In Barangay Siapar in Anda, fish stocks were already gasping, Rosario said. He warned fish growers about another neap tide this weekend.

Pangasinan Rep. Jesus Celeste said the fish kill forced growers to harvest about 500 tons of bangus that they could still sell. But half of the harvest went to waste as ice plants in Bolinao and nearby towns ran out of supply to preserve the fish, he said.

“I thought the fish kill had stopped after it somehow abated on Monday,” he said.

But a 30-minute rain on Tuesday noon worsened the already precarious water quality situation in aquaculture areas in the town, said Florante Garcia, Bolinao fishery technologist.

On Tuesday and Wednesday, Molina said shipments of bangus from Anda and Bolinao were allowed to be unloaded, but the fish sizes were smaller than the usual harvest. These weighed 200 to 250 grams each, or four to five pieces a kilogram, and were sold at P40 a kg as on Wednesday.

Philippines: Oil spill from Sual power plant threatens 700 fish cages

By Joel Locsin, 28th October 2014;

An oil spill from the coal-fired Sual power plant in Pangasinan is threatening some 700 fish cages in the area.

The sight of thick oil and dead fish startled residents in the area since early Monday morning, GMA Dagupan’s Joyce Segui reported on GMA News’ Saksi.

“Confirmed that we have an oil spill because of pipe rupture sa isa sa aming mga facilities,” said Jessa Calaunan of Team Energy Sual.

Since the oil spill is near 700 fish cages, many fear the incident may affect local mariculture and marine fishing industries.

The Sual mariculture park produces 20 metric tons of bangus (Milkfish) (Chanos chanos) and 10 metric tons of pompano (probably Snubnose Pompano) (Trachinotus blochii). Most are sold in Metro Manila.

Municipal environment and sanitation officials have taken samples of the water.

The Department of Environment and Natural Resources in Region 1 has taken efforts to prevent the spill from spreading.

Provincial environment officials are also monitoring the incident.

Lots of dead farmed fishes at Lim Chu Kang, and now also at Kranji
By Ria Tan, 21st October 2014;

More dead farm fishes washing up at Lim Chu Kang this morning.

I also saw dead farm fishes washing up at Kranji Reservoir Park.

I noticed a small boat next to Lim Chu Kang Jetty with four people wearing bright orange lifevests. They were busy removing floating dead fishes with a small net and bagging them.

There were many dead fishes floating near the mangroves too.

Many fishes had already ‘landed’ on the mangroves.

Most of the fishes were rotting, so it is likely to be the same ‘batch’ that washed up yesterday. This round of dead fish seems similar to the one that I saw on Friday.

Lots of dead farm fishes washed up at Lim Chu Kang and Sungei Buloh
By Ria Tan, 20th October 2014;

Lots of dead farm fishes washed up at Lim Chu Kang today. Lots also washed up at Sungei Buloh Wetland Reserve.

At Lim Chu Kang, I saw Veolia workers working hard to remove the large number of fishes.

When I arrived, I noticed three Veolia trucks parked near the jetty, and lots of yellow trash bags on the high water mark.

The bags contained dead farmed fishes, the same kind that have been washing up since Friday.

There were five people busy cleaning up the high water line of dead fishes.

Lots of dead fishes piled up along the high water mark.

The line of washed up dead fishes went all the way into the mangroves.

The line of dead fishes continued into the mangroves, following the high water mark. Here’s a snapshot of the fishes washed up on the high water mark.

The fishes seem to have been dead for a while, but quite recently. Some still had their eyes, but their tails were already tattered.

Most didn’t have bloated bodies or popping out scales, which happen as the fishes start to decompose.

I saw only a few fishes on the low water mark and didn’t see any floating in the water.

Have these dead fishes reached Sungei Buloh too?

Sadly, yes. At Sungei Buloh, the boom had been deployed to stop the dead fishes from floating deeper into the Reserve. It is heartbreaking to see that NParks has to work extra hard to protect our Reserves simply because fish farms do not dispose of dead fishes responsibly.

Lots of dead fishes had also floated up at Sungei Buloh’s western shoreline.

This round of dead fish seems a lot more than the one that I saw on Friday.

Dead fish checks: Lim Chu Kang and Sungei Buloh
By Ria Tan, 20th October 2014;

It was a relief not to see masses of dead fishes at Lim Chu Kang on both Saturday and Sunday. This portion of the shore had a line of dead farmed fishes on Friday. Sadly, I got word of some dead fishes found at West Coast Park.

On both Saturday and Sunday, I checked a 20m stretch of mangroves. There were a handful of freshly dead farm fishes on the mid-water mark. The fish eyes were still intact.

I only saw a handful of freshly dead farmed fishes on the low water mark. There were no new dead fishes on the high water mark, although there were several rotting old dead fishes there.
