Unsustainable development threatens the diverse fish populations of the Mekong river, with one-fifth of fish species facing extinction, a new report by conservation groups said. But some scientists say it's "not too late" for countries in the delta to reverse the adverse impacts.

One in five fish species in the Mekong River is at risk of extinction due to unsustainable development practices, according to a recent report by conservation groups. The diverse fish populations of the Mekong are being threatened, highlighting the urgent need for action to protect these species.

Despite the alarming situation, some scientists believe that it is not too late for the countries within the Mekong Delta to mitigate and reverse these negative impacts. The call to action emphasizes the potential for change if immediate and sustainable practices are adopted to safeguard the biodiversity of the river.



One in five Mekong river fish facing extinction

Some of the largest and rarest fish, freshwater fish, anywhere on earth occur in the Mekong River. But a new report says almost one-fifth of the known fishes in the Mekong, one of Asia's longest rivers, are threatened with extinction, though scientists say it's not too late if we change course now. I don't think it's too much to ask to find ways to develop the river sustainably and still maintain these incredibly productive and diverse fisheries that have supported people for thousands of years. In the Mekong River lives a dazzling range of fish species, among them the world's largest catfish, largest carp, as well as freshwater stingrays thought to weigh more than 1,100 pounds. But a collaborative report published on Monday by more than 20 conservation groups issued a warning about the world's third most biodiverse river after the Amazon and Congo. It says unsustainable development has put 74 fishes at risk of extinction, with 18 species already critically endangered. Zeb Hogan, a University of Nevada biologist and head of the USAID Wonders of the Mekong Project, was part of the Mekong's Forgotten Fishes report. There are new discoveries of freshwater species, fish species, every year. So the Mekong River is still full of diversity, full of species that have yet to be described. And so there's the potential, as the basin is developed, that we might lose species before they're even known to science. Flowing through six countries, from the Tibetan Plateau to the South China Sea, the river is also the world's largest inland fishery. And a depletion of catches could threaten food security for some 40 million people across Southeast Asia, as well as China. Among the causes, Hogan pinpoints the development of hydropower dams as the main culprit that fundamentally impacts the river system. And he says it's crucial that countries in the delta coordinate efforts to reverse the damage done now, because the data show it's not too late to turn the tide. No species have gone extinct. The fisheries are still incredibly productive. And so what that tells us is, if we take action, collectively take action, to develop the river sustainably, there's still hope for the fisheries, the fish, and the people that depend on them.
