An colossal stingray stuck within the Mekong river has been touted via scientists as the largest freshwater fish ever documented.
The 300kg (661lb) feminine stingray has usurped a 646lb (293kg) massive catfish stuck in Thailand in 2005 from its position because the record-holder, scientists say.
The Mekong river is the 12th longest river on the earth and the 3rd longest in Asia, flowing from the Tibetan Plateau thru China, Myanmar, Laos, Thailand, Cambodia, and Vietnam.
Its boundless biodiversity has observed the Mekong come to account for 1 / 4 of the arena’s freshwater fish catch, consistent with WWF. But overfishing has brought about fish populations and catches to fall, threatening to inflict irreparable harm on its prone ecosystem.
Zeb Hogan, a biologist who leads Wonders of the Mekong, a USAID-funded conservation venture, stated: “In 20 years of researching giant fish in rivers and lakes on six continents, this is the largest freshwater fish that we’ve encountered or that’s been documented anywhere worldwide.”
“Finding and documenting this fish is remarkable, and a rare positive sign of hope, even more so because it occurred in the Mekong, a river that’s currently facing many challenges,” added Dr Hogan, who may be a professor on the University of Nevada, Reno.
Wonders of the Mekong works along the Cambodian Fisheries Administration to ascertain a community of fisherman who alert the researchers in the event that they catch massive or endangered fish.
And on 13 June, in the course of the evening, the scientists gained a decision from a neighborhood Koh Preah fisherman, telling them he had stuck a “very big” stingray. He later took house a $600 (£490) praise for the outstanding to find.
The 3.98m lengthy and a pair of.2m large fish used to be fitted with an acoustic tag to trace its long term motion, ahead of being launched again into the river.
The stingray vanished below the muddy waters of the Mekong round nightfall when the moon used to be already up within the sky, Dr Hogan stated.
The fish is named “Boramy”, which means that complete moon within the native Khmer tongue.
“The stingray find is evidence that the natural world can still yield new and extraordinary discoveries, and that many of the largest aquatic creatures remain woefully understudied,” Dr Hogan stated.
The massive freshwater stingray is an endangered species and this discovery is the second one of its sort to be tested via the staff since May, the primary having weighed 181kg.
“When record fish are found, it means the aquatic environment is still relatively healthy. This is in contrast to what we’ve seen in places like the Yantgze River, where scientists reported the extinction of the Chinese paddlefish,” Dr Hogan stated.
“The Mekong’s deep pools sustain life far beyond these impressive giants. Spawning in this critical habitat produces billions of fish every year which ensure the food security and livelihoods for millions of people in Cambodia and Vietnam.”
