A new fish kill happened last week, on Mestizo River in Barangay Callaguip, Caoayan, Ilocos Sur, fisheries officials reported yesterday. Bureau of Fishery and Aquatic Resources (BFAR) Officer Benny Saraos who is based in this province reported that more than 1,000 pieces of marketable size of "tilapia," valued around ₱25,000, turned up dead in Mestizo River. "The dead fish were immediately buried upon collection from the river's water to avoid its possible delivery for sale into the public market," Saraos said.
