Philippines: Lake Buhi in state of calamity due to fish kill
By Erwin Colcol, 1st December 2016;

Lake Buhi in Camarines Sur has been declared a state of calamity due to massive fish kill, a television report said.

Citing local officials, GMA News’ Unang Balita reported Thursday morning that up to 1,000 fish cage owners have been affected by the fish kill.

Authorities said fish kill usually occurs after continuous rain for several days, adding that chemicals from fish feed also cause deaths of fish.

They said an estimated P500,000 in local revenue has been lost because of the fish kill.

Buhi government officials had met with Bureau of Fisheries and Aquatic Resources experts and civilian volunteers to discuss ways to address the problem.

Philippines: Chemicals in Tilapia feeds, changes in temperature cause Lake Buhi fish kill; town in state of calamity
By Ruel Saldico, 25th November 2016;

A state of calamity was declared in this municipality because of the occurrence of a fish kill over the past few weeks, delivering a big blow to almost a thousand fish cage owners and operators. The initial estimate of damage is at least half a million pesos.

Mayor Margie Aguinillo said that while it is the Tilapia (Oreochromis sp.) species devastated by the occurrence, what is disturbing is that even the smallest fish species endemic to the lake, the Philippine Goby (Pandaka pygmaea actually Mistichthys luzonensis) or “sinarapan,” have also been wiped out.

The Bureau of Fisheries and Aquatic Resources (BFAR), however, said the fish species still exists, but only in lakelets around Lake Buhi and not in its massive expanse which is prone to bacteria, especially during the rainy season.

Fish kills have been a common occurrence in the lake in the months of September-November, said Aguinillo, and this is due to several factors such as the sudden change of temperature in the lake and an increase in bacteria.

Last Thursday, she met with civilian volunteers, the Philippine Coast Guard (PCG), and the BFAR; and concluded that water contamination in Lake Buhi could also be traced to the chemicals introduced in the lake in the form of feeds given to Tilapia in fish cages.

One of the immediate solutions agreed upon was to establish a detachment of the Coast Guard Auxiliary Unit here that will ensure no more additional fish pens will be built in the lake to avoid overcrowding and that existing fish cage operators will refrain from using chemicals to feed their Tilapia.

Philippines: Whales and dolphins have own cemetery too

By Frank PeƱones Jr., 25th October 2016;

Whales and Dolphins here are assigned their own graveyard too.

Dead sea mammals, which are collectively called cetaceans, have been allotted a burial place at the Bureau of Fisheries and Aquatic Resources (BFAR) Regional Freshwater Fisheries Center (RFFC) in Barangay Fabrica in Bula, Camarines Sur.

“We have so far a dozen cases of dead Whales and Dolphins found or stranded in the beaches of Bicol, so we thought of burying them properly, and that’s how the Cetacean Cemetery came to be,” Noni Enolva, spokesperson for BFAR, in Bicol said.

She added that a Dwarf Sperm Whale (Kogia sima) found in Ragay in April 2014 was the first cetacean to have been buried in the cemetery; while the latest were two Spinner Dolphins (Stenella longirostris) found in Tinambac town in July this year.

Cetaceans are a widely distributed family of finned and carnivorous aquatic mammals, which include Whales, Dolphins and Porpoises.

Enolva said that when these dead mammals are found, they are brought to the RFFC for necropsy to determine the probable cause of their death by members of the Fisheries Regional Emergency Stranding Responding Team.

Some causes of death include ingestion of plastic and other solid wastes and acoustic trauma, a sensory hearing loss caused by dynamite explosions or seafloor drilling.

“They become deaf due to these explosions and eventually lose their equilibrium, so they drown. A deaf whale is a dead whale,” Enolva said.

Philippines: Fish kill damage reaches P100 M
By Louise Maureen Simeon, 21st October 2016;

Losses due to the fish kill in Lake Buhi in Camarines Sur have reached P100 million, the Bureau of Fisheries and Aquatic Resources (BFAR) said yesterday.

“Damaged Tilapia may reach 100 metric tons,” said Nonie Enolva, BFAR-Bicol chief.

Enolva said earlier reports that losses have reached P178 million are premature, noting that they are still collating information from concerned local government units.

The BFAR regional office said restocking of fish cages should be suspended until it has been determined that the lake is favorable for fish culture.

The agency also called for the cleaning of sediments and clearing of Water Hyacinths (Eichhornia crassipes) to improve water circulation.

BFAR said it would set a limit on the number of fish cages to be installed per operator and enforce compliance with reportorial requirements on production as well as stricter ecological solid waste management.

Tilapia (Oreochromis sp.) fingerlings will be provided to affected fish pen operators, it added.

Enolva said the fish kill occurred after Typhoon Karen generated inland waves that caused the upwelling of Lake Buhi.

Examination conducted by BFAR showed a compromised level of dissolved oxygen ranging from sub-lethal to normal.

Philippines: Lake Buhi fish kill brings P178M in loss
By Juan Escandor Jr., 20th October 2016;

The amount of losses from a fish kill that struck Lake Buhi in Camarines Sur province after Typhoon “Karen” slammed into the Bicol region has reached P178 million, reports from the Bureau of Fisheries and Aquatic Resources (BFAR) said.

More than 50 km from this city, the 1,600-hectare Lake Buhi in Buhi town is the biggest inland body of water in Bicol where Tilapia (Oreochromis sp.) fish culture has been extensive since the 1980s. It is also the home of Sinarapan (Mistichthys luzonensis), a goby species considered to be the smallest commercial fish in the world.

Nonie Enolva, BFAR spokesperson, said the agency’s “conservative estimate” showed that each fish cage operator lost at least P1 million as a result of the fish kill.

Enolva said the fish kill, which started on Oct. 15, happened because of “compromised dissolved oxygen level,” when lake water was disturbed and its level increased due to strong wind and heavy rain whipped up by the typhoon.

Fish stress

“[Lake condition] caused extreme stress to cultured fish,” she said.

Beethoven Nachor, Buhi municipal administrator, said a local government team would assess the environmental impact of the fish kill, account for the number of families affected and prepare a mitigation plan.

Nachor said the team would conduct a cleanup drive since some fish cage operators either left Tilapia rotting in cages or dumped them in the lake.

He said 16 percent of Lake Buhi had been occupied by fish cages, which is 6 percent more than the size allowed for aquaculture development.

History of losses

Nachor said the price of Tilapia has gone down to as low as P5 per kg from a high of P120 per kg after the fish kill.

In 2011, Lake Buhi was also hit by a massive fish kill, with losses estimated to reach P80 million.

Dennis del Socorro, BFAR Bicol regional director, asked the Buhi government to enforce a local law that sets the size of the lake to be devoted to aquaculture to just 10 percent to prevent another fish kill.

Del Socorro also recommended the suspension of re-stocking of cages until the BFAR declares lake water to be favorable for fish culture again.

He said the local government must inventory fish cage operators and set limits on the number of cages they operate.

Philippines: P9-M worth of fish affected by fish kill in CamSur
By Rizza Mostar, 18th October 2016;

At least P9 million worth of Tilapia (Oreochromis sp.) have gone to waste as 95 percent of the fish being grown in Lake Buhi were affected by a fish kill incident.

Overcrowding is seen as the possible cause of the frequent incidents of fish kill in Lake Buhi as over 15,000 fish pens are situated in the lake. This amount is 10 percent more than the ideal capacity of breeding pens in the lake.

Rotten fish are now seen at the lake and a clean-up drive is underway, the Lake Development Office (LDO) said.

The LDO is still waiting for the water sampling result from the Bureau of Fisheries and Aquatic Resources (BFAR) to determine the proper solution to end the fish kills in the lake.

For now, the local government has committed to give fingerlings to affected operators who are registered and are paying the right taxes.

Six Striped Dolphins stranded yesterday in Malaconini, Siruma, Camarines Sur. Four of them were released yesterday and today. The other two, unfortunately, died. Necropsy of the two dolphins suggests that they were victims of blast trauma (dynamite fishing)… Many thanks to BFAR 5-FIRST for their continued efforts in responding to marine mammal strandings in the Bicol region.
