BULACAN, Philippines – The Bureau of Fisheries and Aquatic Resources (BFAR) visited fishponds in Obando, Bulacan Monday, May 7, to find out what could have caused the massive fish kill in the area that started Saturday, May 5.
The fish kill has now affected seven barangays namely Pag-Asa, Pangulo, Paliwas, San Pascual, Pulo, Paco and Tawiran.
BFAR Region III said the cause of the fish kill was likely the lack of oxygen in the water in the area.
“According sa na-observe ng mga tao dito, probably dissolve oxygen kasi sa ganyang magnitude sa dami ng namatay na isda ang pagkawala ng lang ng oxygen sa tubig ang pwedeng makapatay ng isda na marami,” Jun Coloma, a senior agriculturist.
BFAR has taken water sample from the affected fish ponds for further testing.
According to Fredy Sta. Maria, the Junior OIC of the Municipal Agriculture Office, the fish kill has already damaged millions worth of fish.
“Ang stocking kasi per hectare dito 10,000 pieces na fingerlings. Ang amount na na-damage is roughly P20 million to P30 million sa initial palang iyon, sa Barangay Pag-Asa pa lang yun,” he said.
BFAR hopes that by next week the condition in fishponds in Obando will return to normal. – Nestor Torres | UNTV News & Rescue
MANILA, Philippines – A video taken by Regine Nequia, president of Baseco Seaside Neighborhood Association (BASA), showed dead fish floating in Manila Bay near the Baseco Compound on Thursday (September 17) morning.
She said that a similar incident have happened in the past, but the amount of dead fish has not been as large.
Residents are asking authorities to look into the matter not only because their livelihoods depend on the bay, but also because of the stench coming from the rotting fish.
“Ang mga nawalan ng trabaho dyan kumukuha ng pangaraw-araw ding ulam, [Residents who lost their jobs get their daily meal from the fish there],” Nequia said.
“Iyog mga mangingisda naman sa ngayon ay sadyang nababahala kasi dyan nila kinukuha yung kanilang pangkabuhayan, [Fishermen, meanwhile, expressed concern over the incident as they depend (on the bay) for their income],” she added.
The Department of Environment and Natural Resources (DENR) has refuted claims that the dolomite or artificial white sand being dumped along Roxas Boulevard was the cause of the fish kill in the bay.
According to Environment Undersecretary Benny Antiporda, the Baseco area is way far from Roxas Boulevard and the two sections are divided by a breakwater.
He also noted that it seems impossible that the fish kill happened only in Baseco area but not in the Roxas Boulevard area where the dolomite dumping is located.
“It’s impossible na iyong fish kill nandoon lang sa lugar nila pero ang nourishment nandito sa kabila. Also, there is a big divider which is the breakwater so it is really impossible na dito sa atin nanggaling iyon,” Antiporda said.
The official cited similar incidents of fish kill that occurred in October last year which happened in the portions of Las Piñas and Parañaque but that was caused by the lowering of oxygen level in the water.
Nonetheless, Antiporda is not discounting the possibility of a sabotage or someone putting poison in that part of the bay to discredit the ongoing beach nourishment project.
“Mas gusto natin tingnan iyong positive side rather than may nanabotahe but hindi din namin dini-discount iyan at tinitingnan naming mabuti kung meron pa rin bang cyanide fishing,” he said.
The agency has taken water samples from Baseco area and from the site of the white beach project to help in the investigation. MNP (with reports from Rey Pelayo)
Based on the latest laboratory results of BFAR and the local government units (LGUs), shellfish collected from coastal waters of the following areas are still positive for paralytic shellfish poison that is beyond the regulatory limit:

The agency reminds residents that “all types of shellfish and Acetes sp. or alamang gathered from these areas are not safe for human consumption.”
MANILA, Philippines — The Bureau of Fisheries and Aquatic Resources (BFAR) Region 4A has reported that around 800 metric tons of fish died in Laguna Lake last week in the areas of Pililia and Binangonan, Rizal.
Region 4A Director Sammy Malvas clarified that the fish kill was due to the lowering of dissolved oxygen in the water and not because of any virus outbreak as some reports said.
“Kalimitan ang cause nyan ay iyong pabago-bagong weather condition natin. Halimbawa ay mainit sa araw tapos bandang hapon ay biglang bubuhos ang malakas na ulan, nagko-cause iyon ng pagbaba ng lebel ng dissolved oxygen, (Usually, the cause is the changing weather conditions. For example, the sun is up in the morning then in the afternoon, we have thunderstorms, that causes reduction in level of dissolved oxygen),” Malvas explained.
One of the viruses that can infect tilapya is the so-called ‘tilapia lake virus’ (TLV), a case of which was recorded three years ago in Bulacan.
There has been no recurrence of such incident so far according to Malvas, as they also conduct strict laboratory testing of fish seed samples before transporting them to other places.
“Nag-i-issue kasi tayo ng health certificate para doon sa transboundary movement ng mga buhay na semilya (We issue health certificates for transboundary movement of live fish seedlings),” Malvas said.
The supply of tilapia at the Balintawak Market comes from Pampanga and Batangas and there has been no price increase.
BFAR assured that fish supplies in the market are safe to eat provided they are thoroughly cooked. MNP (with reports from Rey Pelayo)
