Bohol, Philippines - The Bureau of Fisheries and Aquatic Resources (BFAR) in Central Visayas issued a warning on Monday for beachgoers in Bohol to be cautious of high concentrations of jellyfish near Panglao and Tagbilaran City.
According to Philippines News Agency, spokesperson for BFAR-7, large swarms of jellyfish were observed at Napaling Point in Barangay Tangnan, Panglao, and Mabaw Reef in Barangay Taloto, Tagbilaran City. He explained that such gatherings are a natural occurrence linked to ocean dynamics and nutrient-rich waters, which are common in tropical regions like the Philippines. Tejada noted that the phenomenon tends to occur when the water temperature rises, which has been the case as reported by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration amid fluctuating weather conditions due to intermittent low-pressure areas.
Tejada further explained that the increased presence of phytoplankton during hot weather, which performs photosynthesis, attracts jellyfish, as they primarily feed on these planktons. The recent sightings were also confirmed by videos circulating online, showing thousands of 'bolbog'—as the jellyfish are locally known—swarming off the coasts of Panglao Island and Tagbilaran City.
He emphasized the hazards posed by jellyfish stings, which can trigger allergic reactions, including itchiness, swelling, and respiratory issues such as shortness of breath, coughing, and wheezing. As a precaution, Tejada advised against swimming in areas where jellyfish are present to avoid potential health risks.
