The City Agriculture Office (CAO) in Dagupan City has warned milkfish (bangus) growers to take precautionary measures against a possible fish kill or tangok. City agriculture officer Emma Molina explained that at this time of the year fish kills are prevalent as the temperature underwater changes with the season. Molina said that based on past experience, the fish kill usually happens at the end of cold season when the summer season starts.
