Largest ever freshwater fish caught; it is a stingray at 13 toes lengthy and greater than 600 kilos

BANGKOK – The world’s largest recorded freshwater fish, an enormous stingray, has been caught within the Mekong River in Cambodia, based on scientists from the Southeast Asian nation and the US.

The stingray, captured on June 13, measured virtually 13 toes from snout to tail and weighed slightly below 660 kilos, based on a press release Monday by Wonders of the Mekong, a joint Cambodian-US analysis undertaking.

The earlier document for a freshwater fish was a 646-pound Mekong big catfish, found in Thailand in 2005, the group mentioned.

The stingray was snagged by a neighborhood fisherman south of Stung Treng in northeastern Cambodia. The fisherman alerted a close-by workforce of scientists from the Wonders of the Mekong undertaking, which has publicized its conservation work in communities alongside the river.

The scientists arrived inside hours of getting a post-midnight name with the information and had been amazed at what they noticed.

“Yeah, whenever you see a fish this dimension, particularly in freshwater, it is laborious to understand, so I feel all of our workforce was surprised,” Wonders of the Mekong chief Zeb Hogan mentioned in an internet interview from the College of Nevada. Reno. The college is partnering with the Cambodian Fisheries Administration and USAID, the US brief worldwide improvement company.

Freshwater fish are outlined as people who spend their complete lives in freshwater, versus big marine species comparable to bluefin tuna and marlin, or fish that migrate between contemporary and saltwater like the large beluga sturgeon.

The stingray’s catch was not nearly setting a brand new document, he mentioned.

“The truth that the fish can nonetheless get this huge is a hopeful signal for the Mekong River,” Hogan mentioned, noting that the waterway faces many environmental challenges.

The Mekong River runs by means of China, Myanmar, Laos, Thailand, Cambodia and Vietnam. It’s house to a number of species of big freshwater fish however environmental pressures are rising. Specifically, scientists concern a significant program of dam constructing lately could also be significantly disrupting spawning grounds.

“Massive fish globally are endangered. They’re high-value species. They take a very long time to mature. So in the event that they’re fished earlier than they mature, they do not have an opportunity to breed, “Hogan mentioned. “Lots of these huge fish are migratory, so that they want giant areas to outlive. They’re impacted by issues like habitat fragmentation from dams, clearly impacted by overfishing. So about 70% of big freshwater fish globally are threatened with extinction, and all the Mekong species. ”

The workforce that rushed to the positioning inserted a tagging system close to the tail of the mighty fish earlier than releasing it. The system will ship monitoring data for the following 12 months, offering unprecedented knowledge on big stingray conduct in Cambodia.

“The enormous stingray is a really poorly understood fish. Its identify, even its scientific identify, has modified a number of instances within the final 20 years, ”Hogan mentioned. “It is discovered all through Southeast Asia, however now we have virtually no details about it. We have no idea about her life historical past. We have no idea about its ecology, about its migration patters. ”

Researchers say it is the fourth big stingray reported in the identical space up to now two months, all of them females. They assume this can be a spawning hotspot for the species.

Native residents nicknamed the stingray “Boramy,” or “full moon,” due to its spherical form and since the moon was on the horizon when it was freed on June 14. Along with the respect of getting caught the record-breaker, the fortunate fisherman was compensated at market fee, which means he obtained a fee of round $ 600.
