Largest freshwater fish ever recorded stuck in Cambodia | Fish

The international’s greatest recorded freshwater fish, a large stingray, has been stuck within the Mekong River in Cambodia, in line with scientists.

The stingray, captured on 13 June, measured virtually 4 metres from snout to tail and weighed slightly below 300kg, in line with a remark on Monday through Wonders of the Mekong, a joint Cambodian-US analysis mission.

The earlier listing for a freshwater fish was once a 293kg Mekong large catfish came upon in Thailand in 2005, the gang mentioned.

The stingray was once snagged through a neighborhood fisher south of Stung Treng in north-east Cambodia. The fisher alerted a group of scientists from the Wonders of the Mekong mission, which has publicised its conservation paintings in communities alongside the river.

The scientists arrived inside hours of having a post-midnight name with the inside track, and had been amazed at what they noticed. “Yeah, when you see a fish this size, especially in freshwater, it is hard to comprehend, so I think all of our team was stunned,” mentioned the Wonders of the Mekong chief, Zeb Hogan.

“The fact that the fish can still get this big is a hopeful sign for the Mekong River,” he mentioned, noting that the waterway faces many environmental demanding situations.

The Mekong runs via China, Myanmar, Laos, Thailand, Cambodia and Vietnam, and is house to a number of species of big freshwater fish, however environmental pressures are emerging. Scientists concern {that a} primary programme of dam construction in recent times could also be critically disrupting spawning grounds.

A tagging tool was once inserted close to the fish’s tail that can ship monitoring knowledge for the following 12 months, offering remarkable information on large stingray behaviour in Cambodia.

“The giant stingray is a very poorly understood fish. Its name, even its scientific name, has changed several times in the last 20 years,” Hogan mentioned. “It’s found throughout south-east Asia, but we have almost no information about it. We don’t know about its life history. We don’t know about its ecology, about its migration patterns.”

Researchers say it’s the fourth large stingray reported in the similar space up to now two months, they all ladies. They assume this can be a spawning hotspot for the species.

Local citizens nicknamed the stingray “Boramy” – that means “full moon” – as a result of its spherical form and as the moon was once at the horizon when it was once freed on 14 June. In addition to the distinction of getting stuck the record-breaker, the fortunate fisher was once compensated at marketplace charge, that means he won a cost of about $600.

“Big fish globally are endangered. They’re high-value species. They take a long time to mature. So if they’re fished before they mature, they don’t have a chance to reproduce,” Hogan mentioned.

“A lot of these big fish are migratory, so they need large areas to survive. They’re impacted by things like habitat fragmentation from dams [and are] obviously impacted by overfishing. So about 70% of giant freshwater fish globally are threatened with extinction, and all of the Mekong species.”
