What is killing fishes at Pasir Ris?
By Ria Tan, 25th February 2015;

I headed out in the afternoon to see if dead fishes were washing up at Pasir Ris Park beach.

There was a huge dead barracuda, and a few other large dead fishes. I didn’t see many dead farm fishes. Dead wild fishes were also reported over the last two days at Sembawang and Changi. The risks of fish deaths are rising in the weeks ahead as there will be no good spring tide to flush the waters around Pasir Ris and Pulau Ubin until April.

I checked out the western side of Pasir Ris today, the same stretch I checked three days ago on 22 Feb (Sat). Alas, today I came too late and the cleaner had already cleaned the high water tide line for the day. So I only checked the low water line of the most recent tide.

I also surveyed a stretch of beach wasn’t cleaned yet. So I could check the high water tide line for today. Here, I saw a few very crispy large dead fishes.

I also surveyed the western stretch of shoreline that is outside the Pasir Ris Park proper and thus is not cleaned at all. Here, I saw some really large dead fishes.

Thailand: Phuket mystery: Autopsies yield no results for reef fish deaths
By Chutharat Plerin, 15th October 2014;

Autopsy results of dead fish collected at Koh Racha Yai off the southern coast of Phuket have yielded no clues as to why scores of reef fish are being found dead in the area (story here).

“We have yet to determine the cause of death. Experts conducted autopsies, but the results were inconclusive,” Phuket Marine Biological Center (PMBC) Director Ukkrit Satapoomin told the Phuket Gazette yesterday.

“Also, we checked the water conditions thinking that perhaps an influx of cold, less-oxygenated water transferred with more oxygenated water in the reef areas. However, that was not the case”

The other possibility is humans, Mr Ukkrit said.

“We have contacted people within our network and asked them to keep an eye out for any possible illegal fishing that might have caused the deaths. At this point, however, we do not want to make any unsubstantiated allegations,“ he explained.

“I have also contacted the Phuket Office of the Department of Marine and Coastal Resources (DMCR) for additional ideas on what could be done to prevent the deaths from continuing.”

After the reports concerning the dead fish off Koh Racha Yai, reports of dozens of dead fish found along Nai Harn Beach surfaced.

“We cannot do this alone. People must not be afraid to contact us if they are able to document illegal fishing,” said Department of Marine and Coastal Resources (DMCR) Region 5 Chief Tanet Munnoy.

“I am available 24-7, so call me on my mobile if you witness fishermen fishing in restricted areas or using illegal fishing practices. My number is 081 636-8099.”

Philippines: Environmental Management Bureau (EMB) forms body to probe fishkill

By Nitz Arancon and Lito Rulona, 2014;

The Environmental Management Bureau (EMB) has created a water quality management group in response to the fiskkill at the Agusan River here last weekend.

A local envionrment official described it as one of the biggest fishkills in the city so far in recent years.

The group is headed by EMB with local government officials, including those in Manolo Fortich and Libona towns in Bukidnon and Misamis Oriental, serve as members.

The group was formed in order to look into suspicions that plantations, poultry farms and piggeries in Bukidnon, particularly the ones in Libona and Manolo Fortich, factored in the fishkill at the Agusan River on Saturday and Sunday.

City local Environment and Natural Resources officer Edwin Dael confirmed that it has been suspected that toxic wastes from the Bukidnon towns resulted in the fishkill.

Bisan ang mga isda sa suba sa Balubal, patay man gihapon,” said Dael. “Ma-o na kini ang labing dako nga fishkill so far sa Cagayan de Oro kay ti-aw moy duha ka adlaw.”

The dead fishes were mostly anga (Red-tailed Goby) (Sicyopterus lagocephalus), banak (mullet) (F. Mugilidae), tangkig (eel) (Anguillidae or Synbranchidae) and pigok (Tapiroid Grunter) (Mesopristes cancellatus) that are endemic in Cagayan de Oro and Misamis Oriental.

The Bureau of Fisheries and Aquatic Resources (BFAR) took water samples from the Agusan River for examination.

Mayor Oscar Moreno has called on the EMB and BFAR to speed up the investigation to determine what really caused the fishkill.

Dael said fishkills have been taking place in the city in recent years but the result of any investigation has not been made public.

He said Moreno directed him to closely coordinate with the EMB and make sure that the Bureau would act on the matter.

“We asked the EMB director to call for a meeting this week and conduct and investigation. Mayor Moreno said he wants someone to answer for the fishkill and that the EMB should file cases in the event that those responsible are operating outside the city,” said Dael.
