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. —Erwin Colcol/LBG, GMA News
