The red tide alert has been raised over three provinces on the island of Panay. The Bureau of Fisheries and Aquatic Resources (BFAR) said they recorded red tide alert in Aklan, Capiz and Iloilo provinces. Red tide refers to algal bloom or a concentration of aquatic microorganisms caused by dinoflagellates, with the bloom taking on a reddish or brown color. These are associated with the production of toxins, depletion of dissolved oxygen or other effects described as harmful.
