More than 800 tonnes of fish have died and rotted on fish farms in a lake near the Taal volcano south of Manila, which authorities blame on a sudden temperature drop.

The mass fish deaths started late last week and have since eased. The dead fish are being buried by the truckload.

An initial investigation showed the deaths may have been caused by the temperature change as the rainy season set in after a scorching summer, which depleted the lake's oxygen levels. Fish were seen swimming in circles before they floated dead to the surface.
