The whipray, measuring at 185 cm in width, 200 cm in length and weighting 180 killogram, was accidentally hooked by a fisherman in Siem Bouk district’s Koh Preah Village

According to WWF, the world’s biggest freshwater fish and 4 out of the top ten giant freshwater fish species can be found in the Mekong River which flows through Cambodia, China, Lao PDR, Myanmar, Thailand and Vietnam.
