In a Sri Lankan village on the brink of ecological disaster, local fishermen are harnessing an unlikely opportunity. A new invasive species, the snakehead fish, has invaded the Deduru Oya reservoir, devouring traditional catch and threatening livelihoods, but also presenting an untapped market for a unique product.
Over two years ago, fishermen first noticed a decline in their typical catches, while snakeheads, previously unknown in Sri Lanka, began to appear in abundance. Local officials believe that these invasive fish likely arrived with imported ornamental fish, released into the reservoir when they outgrew home aquariums.
The snakehead's absence of natural predators in Sri Lanka's ecosystem has created an ideal breeding ground, with ample food and no predator pressure. "The Deduru Oya reservoir has provided them with an ideal breeding ground with ample food and no predator," explained Dr. Kelum Wijenayake, a researcher studying the fish.
These formidable creatures can surface to breathe air, survive with minimal water, and feed aggressively. Native freshwater species are vastly outmatched by the snakehead's size and feeding habits. Fisherman Nishantha Sujeewa Kumara has reported catching an impressive 7kg specimen, far exceeding native species' typical weights of less than 1kg.
While initially perplexed to encounter this foreign species, local fishermen have since come to see potential benefits in their presence. An angler competition aimed at controlling the snakehead population ultimately proved unsuccessful, but a more sustainable approach is being explored.
Ranjith Kumara, secretary of the fishers' association, suggests promoting angler tourism as an alternative income source for villagers reliant on fishing and farming. "We started fishing in this reservoir in 2016... now they've become very rare," he noted.
Fisherman Sujeewa Kariyawasam is capitalizing on the demand for dried snakehead products. While fresh versions have limited market appeal, the dried variety is gaining popularity due to its flavor. As demand continues to grow, more snakeheads will be caught for production, helping to control their spread and create a new revenue stream for local communities.
This unusual situation highlights both the challenges posed by invasive species and the resourcefulness of those who depend on fishing as their primary livelihood. By embracing this unexpected opportunity, Sri Lankan fishermen are proving that with determination and creativity, even ecological threats can be turned into sustainable advantages.

just saw this story about snakehead fish taking over a reservoir in Sri Lanka... seems like a double-edged sword - on one hand it's devastating for the native catch and livelihoods but on the other hand its popularity is creating new income streams for local communities 
and I gotta admire these fishermen's resourcefulness 
. These snakehead fish might be a nuisance, but they're also creating a new market for the villagers. It's like they're turning a problem into an opportunity 
. I mean, who wouldn't want to try some dried snakehead products? 
But seriously, it's awesome that the fishermen are being proactive about managing their catch and finding ways to make money from it. It shows that even in the face of ecological challenges, there's always room for innovation and resourcefulness 
this dried snakehead product thing is like whoa I mean I wouldn't eat it myself but I guess there are people out there that'd pay good money for it and it's all about adapting to change and finding new ways to make a living in a world where the environment can be really harsh sometimes

. i guess this just goes to show that sometimes, you have to think outside the box (or in this case, the reservoir) to find a solution 
. So, these invasive snakehead fish show up outta nowhere, right? And now local fishermen are making bank off 'em 
. But what's really going on is a classic case of neoliberalism in action 
. I mean, where was the oversight when these ornamental fish were brought into the country? It's like, where's the accountability? 
. These snakeheads are wreaking havoc on the native species, and still, nobody's talking about conservation 
. It's all about short-term gains vs long-term sustainability 
. But hey, at least these fishermen are being proactive and finding ways to adapt 
. Maybe we can learn from their resourcefulness?
I can only imagine how tough it must be for these fisherman to deal with the decline in their traditional catch. But its amazing to see them finding a way to turn this into something positive 
. I mean, who would've thought that an invasive species could become a source of income? Its like the old saying "when life gives you lemons make lemonade" but instead they're making... dried snakehead products 
. Keep up the good work Sri Lankan fisherman! 
.
I gotta say, I'm loving how these Sri Lankan fishermen are getting creative with the snakehead situation 
It just goes to show that with determination and resourcefulness, we can overcome even the toughest challenges 
but instead of being a disaster, the locals are trying to make money off 'em 
they even have an angler competition to try and control the population but so far that's not worked out
