Secrets of the Mekong

Last month brought a little limelight to FISHBIO's international conservation program in Southeast Asia. The environmental and conservation news website interviewed our conservation director, Harmony Patricio, about the importance and challenges of studying Mekong River fishes, and about the recently launched Mekong Fish Network. "The world needs to realize that the Mekong is like the Amazon rainforest," Patricio said of the river's value. "It's a global resource of incredible diversity and productivity." A few excerpts from the interview are below. You can read the full article, accompanied by vivid FISHBIO photos, at


Mongabay: How did you start working in the Mekong?


Harmony Patricio: So many people told me about the amazing fish diversity in the Mekong, how little is known about the lifecycles of most species, how important the fish are for the people living in the Mekong Basin, and how many big changes were on the horizon in Southeast Asia. I had a feeling that the Mekong would be the next hotspot for fish conservation... FISHBIO's primary goal for our international work is to share our technical expertise in the places where it's most needed. I felt like the Mekong region, and Lao PDR in particular, had a high need for technical capacity building to support local scientists.

Mongabay: What makes the Mekong River special in terms of fish?


Harmony Patricio: It has the second largest number of fish species of any river on earth, only after the Amazon River. More than 850 species have been described, and researchers estimate there could be over 1200 species. As a comparison, the whole state of California has about 67 freshwater fishes...What's also special is how important the fish are for the people. There are over 60 million people that depend on the fish for protein and income, and the economic value of the fisheries is as much as $3.8 billion US dollars per year on first sale. So the river's fish are highly diverse, feed a lot of people, and are worth a lot of money.


Mongabay: What do you hope to achieve with your new project, the Mekong Fish Network?

Harmony Patricio:
The main goal of the Mekong Fish Network is to help people working with fish in the different countries of the Mekong Basin collaborate across national borders and share information so we can better understand what's happening with Mekong fishes throughout the basin...We also hope to develop and implement standardized fish sampling methods throughout the basin to build a long-term monitoring program that studies how these fish populations change over time. No basin-wide program like this currently exists, and we need it if we want to achieve more sustainable fisheries management, conserve some of these rare or migratory species that are on the brink of extinction, and sustain the river's productivity that people rely on for food and income.

Purple sea

Spring blooms o f lupine lend shades of blue and purple to otherwise featureless gravel bars and dry side channels in watersheds throughout California. Lupines, like many other legumes, don't rely on soil nitrogen for nutrition. Instead, they have the ability to convert nitrogen gas from the atmosphere into ammonia, a biologically useful form. This ability allows lupines to thrive on infertile substrates, as well as enrich the ground and improve growing conditions for other plants over time.


Of the roughly 300 described species of lupine, the majority contain toxic alkaloids, and lupine poisoning is a  common cause of livestock death in the western US. Despite this fact, people have used the bean pods produced by lupines as a food source for thousands of years. Popular in the Mediterranean since Roman times, the beans require a series of steps to leach the toxins before they can be eaten (such as soaking in salt solution or water, sometimes for several weeks).


In modern times, people have cultivated varieties of lupine containing reduced amounts of toxins, particularly in Europe. These beans are increasingly used in vegetarian cuisine and as a substitute for soy.  Although we can't reach for wild lupine... Read more>

Fish sickened for more than a year after Deepwater Horizon oil, study says
Nature World News

Spilled crude oil from the Deepwater Horizon oil spill in the Gulf of Mexico sickened Gulf fish species for more than a year after the disaster, according to new research. Gulf killifish embryos exposed to sediments from oiled locations in 2010 and 2011 show developmental abnormalities, including heart defects, delayed hatching and reduced hatching success, the researchers report.
Killifish are abundant in coastal marsh habitats along the Gulf Coast... Read more>   

Transgenic salmon nears approval


In the remote highlands of Panama, in tanks protected by netting, barbed wire and guard dogs,  swim the world's most expensive and scrutinized fish. These swift-growing salmon have been at the centre of a 18-year, US$60-million battle to bring the first genetically modified (GM) animal to US dinner tables - a struggle that may be nearing its end. Last week marked the end of the public's opportunity to weigh in on a US Food and Drug Administration (FDA)... Read more>  

Annual report to Congress on the status of U.S. fisheries

The 2012 Annual Report on the Status of U.S. Fisheries highlights the progress that collectively, NOAA Fisheries, the regional fishery management councils, and our stakeholders have made to end overfishing and rebuild stocks. The report documents additional progress towards long-term economic sustainability of our nation's fisheries. Recent economic data illustrates that the overall seafood industry and recreational fishing continue to... Read more 

Cormorant hazing saves juvenile salmon on Oregon coast 
The Oregonian  

Greg Hublou takes a quick pass through upper Tillamook Bay and spots his quarry. A flock of 70 double-crested cormorants sit near the confluence of the Tillamook and Trask rivers. He guns his big jet sled, makes a hard turn around a string of pilings and skims over the water toward the birds. The cormorants - feeding on out-migrating juvenile salmon and steelhead - take wing and flee toward the ocean. "That's the biggest group yet," says Hublou... Read more >   

Forests at risk in Southeast Asia's lower Mekong region
Voice of America

Southeast Asia's Lower Mekong region is set to lose a third of its natural forests in the next two decades, according to a report by the Worldwide Fund for Nature. Forestry experts blame the current pace of deforestation on governments' undervaluing forestry resources. The Worldwide Fund for Nature report, titled "Ecosystems in the Greater Mekong," said between 1973 and 2009 lower Mekong countries chopped down almost a third of their forests... Read more >
