Why fishermen on Laguna Lake are yearning for the rain
The clear blue skies during Muntinlupa mornings stand in stark contrast to the green, pungent substance that currently covers Laguna Lake.
The lake is currently under an algal bloom, a rapid accumulation of algae in water systems and can be recognized by the water’s discoloration.
The largest lake in the country which is bordered by Laguna, Rizal, and Manila is currently colored a deep green. It is a testament to how massive the bloom is.
On the Muntinlupa side, the municipal cleanup crew of the Tulong Panghanap Buhay sa Disadvantaged (TUPAD) participate in a cleanup early in the morning, busying themselves by clearing water hyacinths, garbage coated in thick green muck, and other contaminated debris from the lake’s shore while wearing masks against the stench.
The stench is caused by rotting algae, exacerbated by the summer heat.
But for Muntinlupa City Laguna Lake Management Office (LMO) Officer in Charge (OIC) Rosalina Contreras algal blooms are nothing new.
She recounts that the biggest algal bloom that happened here was in 1979. Since then, it has been happening every year.
“Sanay na kami diyan,” (We are used to it), adding “Nangyayari yan kasi dahil sa ‘uncontrolled heat.’” (It happens because of uncontrolled heat.)
Fish pen operators here agree that algal blooms usually happen during summer, but this summer has been different. The heat has continued well into June.
In Barangay Bayanan, Muntinlupa, from a nearby fish pen viewing deck, 38-year-old Muntinlupa Lake guard Ferdinand Balag, and 53-year old Sagip Ilog Environmental Army member Rosario Villamar supervise and participate in the harvesting of tilapia freshly caught from one of the pens further off in the middle of a lake. They lift and load containers of fish onto waiting fish pen workers.
The fish are as fresh as they had been in previous catches, but the fishermen here are cautious. They prefer harvesting early so as to avoid possible fish kill. Residents here say the green algae blooms help somewhat because a normal amount of algae serves as food for the fish.
At the nearby market, not a lot of people buy tilapia that were caught from the pens.
Fish vendor Imelda Eborda, 50, laughs as she says, “Kahit singhutin namin (ang amoy) hindi namin maubos” (Even if all of us inhale the smell, we cant get rid of it.)
She said the fish they are selling aren’t really affected by the green algal bloom.
However, that hasn’t stopped people from not doing business with her. She says that the sale of fish had gone down partly because customers are cautious that the fish might have been “contaminated.”
“Baka daw kasi may lasa.” (They say the fish might taste funny.)
She reasons however, that it might not be solely because of the algal bloom.
“Nagkataon din kasi siguro na pasukan kaya hindi bumibili and mga tao ng isda.” (It could also be because of the start of classes, they have to cut down on their expenses for school needs.)

Like everyone else, Eborda said the only way to be rid of the rotting algae is for the rain to wash it away.
“Basta hinihiling lang naming na umulan na sana. 'Yan lang ang solusyon. Ulan.” (All we're wishing for is rain. Thats the only solution.)
For vendors and fishermen that rely on Laguna Lake to make a living, the rainy season can't come soon enough.
