Earlier this morning at around 10.30am today, a concerned nature lover shared sightings of what looked like hundreds of dead fishes floating into Sungei Buloh Besar with the incoming tide.

I only managed to get there around 3pm and the tide had already gone down. So I saw only some dead fishes at Sungei Buloh Besar as well as the Kranji extension.

Most of the dead fishes were about the same size and look like the Milkfish (Chanos chanos) farmed by the largest fish farm in that area.

Most of the wild fishes seemed alright although there were some Archerfishes (Toxotes sp.) gasping at the water surface at the Main Bridge.

I will check the entire shore again tomorrow.

You CAN make a difference: Dead Fish Alert!

Please help me monitor dead fishes washing up on the Johor Straits. Please let me know if you see large numbers (more than 10) especially of large dead fishes (more than 20cm long) washing up on the northern shores such as Pulau Ubin, Lim Chu Kang, Sungei Buloh, Kranji, Woodlands Waterfront, Sembawang, Punggol, Lorong Halus, Pasir Ris, Changi.

There are too many shores for me to personally check, so I really appreciate any info or photos that you can share. Thank you!

Besides Milkfishes, one of the dead fishes photographed at Sungei Buloh is a Grey Mullet (F. Mugilidae), likely a Flathead Grey Mullet (Mugil cephalus), which is also raised by the fish farms off the coast.

Fish deaths: Fish farmers mentally prepared for more losses, and resigned to fate
The plankton bloom that hit fish farms along the Johor Strait has caused millions of dollars in losses, and plenty of heartache. But while some farmers have decided to simply take it on the chin, others are fighting back. The Straits Times speaks to five farms.
By Carolyn Khew, 9th March 2015;

It has been a tough weekend for 65-year-old fish farmer Ong Kim Pit.

On Friday, his Lim Chu Kang fish farm was hit by mass fish deaths, which had first affected farms in the east of the island.

He lost more than 60,000 baby and adult Mullet fish (Flathead Grey Mullet) (Mugil cephalus), with losses estimated at $10,000.

But he appears to be resigned to his fate.

He said he is aware there are closed rearing systems that can help to isolate fish from the harmful effects of plankton blooms.

But the farmer, who has been in the business for about 20 years, said he is not going to stop using net cages, in which fish are reared in the sea.

When asked why, he said rearing fish in containers is “not so simple” because of the heavy costs involved.

There are also limits on how much fish one can raise in a container, he added.

Besides, the father of three sons, aged 27 to 34, plans to retire in a few years’ time. And he does not want his kids to take over his business as it is a hard life.

“You have to be in the sun and rain a lot and, frankly, I think young people are scared of that,” said Mr Ong.

He said he buys his Mullet and Milkfish (Chanos chanos) fingerlings from Indonesia and feeds them bread and instant noodles for about 11/2 years before he sells them.

He said a similar plankton bloom could see him suffer more loses.

“If I can clear my stock quickly, I’ll do it,” he added.

“The only other thing I can do is to prepare myself mentally. Once the bloom comes, the fish will be gone.”

Fish deaths: Duo turn to online crowdsourcing for help
By Isaac Neo, 9th March 2015;

Fish farming might seem unattractive to most young people, but in the case of 26-year-olds Wong Jing Kai and Bryan Ang, their youth has been a plus.

Last April, the two friends from national service went into partnership with Mr Teh Aik Hua, 60, who owns Ah Hua Kelong.

The farm rears Golden Pomfret (Snubnose Pompano) (Trachinotus blochii), Sea Bass (Barramundi) (Lates calcarifer) and Pearl Groupers (Brown-marbled or Tiger Grouper X Giant Grouper) (Epinephelus fuscoguttatus X lanceolatus), along with mussels and crabs.

The recent plankton bloom wiped out 80 per cent of their entire stock at their farm just five minutes away from Lorong Halus on the north-east coast near Pasir Ris.

The remaining 20 per cent was saved after being moved to their farm in Sembawang.

But they still needed help.

So, the Internet-savvy new partners turned to online crowdsourcing and raised over US$12,000 (S$16,500) through the Indiegogo website.

The money, they said, was needed to help them cover their operating costs. “We are thankful to those who have supported us, it would have been much tougher without them,” said Mr Wong.

They also plan to downsize the Pasir Ris farm and expand their Sembawang farm, which was unaffected by the bloom.

They estimate it will take them at least nine months to get their business back on track and, even then, they may never be able to recover everything. However, they remain optimistic.

They believe their business model which includes delivering the produce straight to households – a plan which the two new partners came up with – is one that will work. Said Mr Ang: “Seafood is something that most Singaporeans really like.”

Checking up on dead fishes at Sungei Buloh
By Ria Tan, 27th July 2014;

On 24 Jul I saw 40 dead fishes at Sungei Buloh in the morning. That same afternoon, I heard the Sungei Buloh Besar river turned black again. The river had turned black the day before, and a lot more dead fishes were seen two days before that.

On 25 Jul, I returned to Sungei Buloh to check on the dead fish situation. I also attended the opening of the Lorong Halus Jetty where for the first time in decades, fish farmers in the East are provided with industrial-sized trash disposal containers dedicated to fish farm trash on the mainland.

There were not many freshly dead fishes. I saw about 30 dead fishes and most looked like they died in the days before.

Dead fish found on the banks of Sungei Buloh Besar yesterday. In a similar incident in April, thousands of dead Grey Mullet were washed up in the wetland reserve.

AVA probes mystery of fish deaths at Sungei Buloh
By Cheryl Faith Wee & Priscilla Goy, 25th July 2014;

Dead fish were spotted in Sungei Buloh Wetland Reserve earlier this week, with parts of Sungei Buloh Besar turning black.

There was also a strong stench – not unlike the smell of rotten eggs – along the main bridge in the reserve when The Straits Times visited yesterday.

Despite several decomposing fish carcasses on the banks of Sungei Buloh Besar, Halfbeaks (likely Stripe-nosed Halfbeaks) (Zenarchopterus buffonis), a native breed of fish, were still seen swimming in the river.

Housewife Sharon Choy, 50, a frequent visitor to the reserve, said: “On Tuesday, when I looked out from the main bridge, I could see the dead fish lining the banks of the river. I told my husband, even if 100 people came to help, they would not be able to clean everything up.”

The water, however, was still clean and had its “usual colour” when she visited.

Nature enthusiast Ria Tan, who runs wildsingapore.com, a wildlife website, said she saw about 40 dead fish along the river yesterday morning.

Most of them looked like the sort of large market-size farmed Grey Mullets (F. Mugilidae), she added.

National University of Singapore biology lecturer N. Sivasothi said mass fish deaths are usually due to two factors – low oxygen levels and poisoning.

Low oxygen levels could be a result of increased algae growth, with algae competing with fish for oxygen. If there are large amounts of fertiliser or sewage upstream, the fish could have been poisoned and flowed into Sungei Buloh.

It was important to monitor the water quality of the Johor Strait, and ensure that offshore fish farms have proper waste disposal facilities, he added.

A spokesman from the Agri-Food & Veterinary Authority of Singapore (AVA) said there has been no report of abnormal fish deaths from our coastal fish farms so far. “We are investigating the fish deaths in Sungei Buloh with the National Parks Board,” he added.

The National Parks Board yesterday said it is removing the dead fish from the reserve.

In a similar incident in April, thousands of dead grey mullet were washed up in the wetland reserve.

The AVA said then that Singapore’s coastal fish farms in the western Johor Strait had not been hit by die-offs and that there had been no plankton blooms or any abnormalities detected.

The agency had also cautioned that it would take enforcement action against farms found to be illegally dumping waste in the water.

Dead fishes at Sungei Buloh Wetland Reserve again
By Ria Tan, 24th July 2014;

This morning I saw about 40 large dead fishes at Sungei Buloh Wetland Reserve.

Dead fishes have been turning up at Sungei Buloh in April and May.

This morning, I saw about 40 dead fishes in my walk from the Main Bridge to Platform 1. Most of the fishes looked freshly (a few days) dead. Most of the dead fishes look like large market-size farmed Grey Mullets (F. Mugilidae) (30-35cm long).

There were a few other large fishes that didn’t look like grey mullets.

In the pond next to the Main Hide, there were a few dead Cichlids (F. Cichlidae) floating among foamy water.

Some dead fishes seen at Sungei Buloh
By Ria Tan, 25th May 2014;

Today, I saw about 10 dead fishes floating at Sungei Buloh. Most looked like large market-size farmed grey mullets, a few looked like large catfishes.

I also observed large fishes jumping out of the water in one of the ponds.

Here’s the floating dead fishes I saw walking from the Main Bridge to Platform 1. Here’s the dead fishes that look like market sized farmed Flathead Grey Mullet (Mugil cephalus) (30-35cm long). Similar to those dead fishes I saw in large numbers last month. Some of the fishes looked freshly dead, others look like they were dead for some time, and I also came across some half eaten skeletons as well as older skeletons.

Western Johor Straits – dirtiest Singapore? @ 18 Apr 2014
By SGBeachBum, 21st April 2014;

News of yet another mass fish death hitting the shores travelled fast.

I decided to see what the condition was like at the north-western bit of Lim Chu Kang on the 18 Apr 2014.

The scenes were unbelieveable… dead fish were everywhere. I think i saw about 200 floaters at various spots around the jetty as well as on the shore and mudflat.

Here are pictures of some of the dead fish. (All of them were mullet which is a species bred in the nearby fishfarms apparently both on the Malaysian as well as on the Singapore side of the Western Johor Straits)
