Philippines: Dolphin dies on Cavite shore; probe launched
By Anthony Giron, 12th January 2015;

A female Dwarf Spinner Dolphin (Stenella longirostris roseiventris), with wounds in the body, died before dawn Saturday on the shore of Barangay Wawa II, this municipality.

Authorities said that the dolphin was still alive when found by a fisherman named Wendel on the shore but had died later, believed due to injuries she had on her body.

Observers believed the dolphin was harmed by someone else who may wanted to catch her while on sea. It was the first time that a dolphin had drifted and died in Rosario (also called Salinas) territory.

Mayor Jose “Nonong” Ricafrente, Jr. has called for an investigation on the death of the dolphin.

The lawyer-mayor said that those liable for wounding the dolphin could be charged for violating Republic Act 8550 (a law against individuals who do not comply to the development, management and conservation of the fisheries and aquatic resources.)

The wounded dolphin on the shore was found by Wendel as he was about to board a banca to catch fish in the sea. Wendel reported the find at once to Nestor Llanoza, Barangay Isla de Bonita (Island of Beauty) chairman.

Municipal Media Affairs Coordinator Sid Samaniego, citing a report of Llanoza, said that the dolphin had several wounds believed inflicted by a blunt, pointed instrument.

Local Bureau of Fisheries and Aquatic Resources (BFAR) Chief Rodel Marasigan said the dolphin was about three-years old, six feet in length and one foot in width and weighs 40-45 kilograms.

What caused the wounds in the dolphin’s body is now under investigation.

Dolphins are reportedly sighted in the waters near El Fraile (Fort Drum) and Corregidor Islands in Cavite City. Rosario is the second coastal town from Cavite City after Noveleta.

The sea area is called “Daang Barko” or “Boat Way” with the numerous fishing and commercial vehicles passing by the turf day and night.

It could not be determined yet as to who indeed had wounded the dolphin that drifted to Rosario shore.

Ricafrente and other municipal officials are one in saying that dolphins, which are intelligent, friendly and playful mammals, would have to be saved and cared for.

Aside from dolphins, butandings (Whale Sharks) (Rhincodon typus), which are endangered species, and other big fish were also sighted in the waters of Rosario and some other coastal municipalities of the province.

Philippines: Toxic pollutants among causes of Cavite fish kill

By Ellalyn De Vera, 29th September 2014;

Low dissolved oxygen level and toxic pollutants have caused the fish kills in Rosario, Cavite last week, according to the Bureau of Fisheries and Aquatic Resources (BFAR).

The BFAR Quick Response Team and the Fish Health Unit personnel of BFAR-Region IV-A were deployed in Rosario, Cavite last September 25 following a reported incident of fish mortality in Malimango River, a four-kilometer river, which starts in Barangay Bagbag 1 and ends in Barangay Ligtong 1 where it opens to Manila Bay.

The river traverses five barangays in Rosario, Cavite namely; Bagbag 1, Bagbag 2, Ligtong 1, Ligtong 3 and, Ligtong 4.

“The stretch of Malimango river is not an aquaculture-producing area and the fish affected by the mortality were wild stock species of Tilapia (Oreochromis sp.), asohos (sand whiting) (Sillago sp.), banak (mullet) (F. Mugilidae) and biya (goby),” BFAR reported.

The loss is estimated at one ton.

“Initial findings indicated that dissolved oxygen (DO) level in all three sampling points—Barangay Bagbag Uno (B), Barangay Ligtong 3 and Barangay Ligtong 4—was below 3-5 mg/L or within the critical level,” it said.

“The water quality test came back with high levels of ammonia-nitrogen, nitrite-nitrogen, and phosphates, beyond acceptable level, in all the sampling sites,” it added.

Ammonia is a chemical compound produced naturally from decomposing organic matter, including plants, animals and animal wastes.

The ammonia in the water samples, however, might have also come from agricultural, domestic and industrial wastes.

Phosphates, meanwhile, are one of the primary nutrient sources for many forms of algae and could come from sources like domestic sewage and runoff from agricultural land, urban areas and green areas.

These chemicals at alarming level have hazardous effects on fish which may result in fish mortality, BFAR added.

BFAR has recommended the necessary management measures during the fish mortality occurrence such as proper disposal of dead fish to ensure that dead fish will not reach the market and prevent the occurrence of sanitary-related diseases.

Philippines: Toxic pollutants among causes of Cavite fish kill

Philippines: 5 industrial firms tagged in fish kill

By Anthony Giron, 29th September 2014;

Some residents tagged at least five industrial firms as suspects in Maalimango River fish kill late last week as concerned citizens asked authorities to look into the incident thoroughly to prevent a repetition of such tributary disaster.

Mayor Jose “Nonong” Ricafrente Jr. said his administration would revive the river with a massive cleanup and fingerlings installation to replace the lost fish and other marine life in the tributary.

Ricafrente said that it may take months or a year for the more than one kilometer-stretch river to get back to life with the actions to be taken.

The lawyer-mayor declared the river dead over the weekend after he found out, through the Bureau of Fisheries and Aquatic Resources (BFAR), that the estuary water contained a chemical deadly for fish and other marine species.

Ricafrente said that the BFAR is set to issue a statement, with their final report, today with regards to the Thursday river fish kill.

The mayor claimed that BFAR’s initial finding revealed that the river fish died “due to lack of oxygen and a still unknown chemical.”

The local chief executive assured that an investigation would be called to trace the chemical source with the BFAR’s report.

Concerned residents, who requested anonymity, said they believed that the deadly chemical came from one of at least five industrial firms with “inactive or no water treatment facilities at all.”

Chemical-emitting factories, particularly those along the river, are required to install the “facilities” to prevent water pollution.

Ricafrente said that he would order the closure of the firm liable for the chemical spill. He likewise cited that he would look into the lapses of concerned agencies on the incident.

Philippines: 5 industrial firms tagged in fish kill

Philippines: After P1-M fish kill, Cavite river now dead — mayor

By Anthony Giron, 27th September 2014;

Municipal officials here tagged Maalimango River as a dead tributary as its waters were found to contain a chemical deadly for fish and other marine life.

Mayor Jose “Nonong” Ricafrente Jr. declared the vital river dead as he said that initial finding of the Bureau of Fisheries and Aquatic Resources (BFAR) revealed that the cause of the Thursday fish kill in the estuary is “lack of oxygen and a still unknown chemical.”

In an interview, Ricafrente said that the finding was based on the initial laboratory analysis report that he obtained from the BFAR at 3 p.m. Friday.

With the finding, Ricafrente ordered the immediate river restriction as well as investigation on the incident.

“It’s dead (referring to the river), the fish and other marine species will not live in the river,” Ricafrente.

Maalimango River is a more than one-kilometer tributary stretch in Barangays Bagbag I and II, Tejero I and Ligtong I, II, III, IV. Old folk said that alimangos (mud or mangrove crabs) (Scylla sp.) once thrived in the river.

The river became a talk of the town when thousands of dead fully grown and small fish such as tilapia (Oreochromis sp.), banak, asubi (both vernacular names for mullet) (F. Mugilidae) and other marine species resurfaced along the river on sunrise of Thursday (Sept. 25).

A swarm of dead fish was first sighted near the mouth of Manila Bay in Bagbag. It was the first fish kill that was reported in the town.

Bantay-Bayan and barangay men hauled off at least one ton of dead fish from the river during the day and Friday. Ricafrente reported that river fish losses may run up to more than P1 million.

Philippines: Fish kill hits Cavite river
By Ed Amoroso, 27th September 2014;

At least two tons of Tilapia (Oreochromis sp.) and bangus (Milkfish) (Chanos chanos) were found floating along the banks of Maalimango River in Rosario, Cavite, an official said yesterday.

Rosario Mayor Jose Nonong Ricafrente said they were still waiting for the results of fish and water sampling tests by the Bureau of Fisheries and Aquatic Resources (BFAR).

He said they were verifying reports that chemicals from factories near the river caused the fish kill. There are at least 300 factories and establishments near Maalimango River.

Ricafrente said he would order the closure of any establishment found to be dumping chemical waste into the river.

Workers buried the dead fish hauled from the river yesterday in a vacant lot.

News reports from other sources mention mullets (F. Mugilidae) instead of Milkfish as being among the main victims of this mass mortality event. Based on the photos, it appears that at least one Common Carp (Cyprinus carpio) was also a victim.
