A fish kill, which affected seven tons of tilapia, has been monitored in Cañacao Bay in Cavite City. Bureau of Fisheries and Aquatic Resources (BFAR) chief information officer Nazario Briguera said an analysis is ongoing. “Based on initial reports, the primary reason for the fish kill was the drop in dissolved oxygen level... There was a significant decrease in dissolved oxygen level in the area and high ammonia nitrogen,” Briguera said.
