Dangerous Amazon Catfish Spreads Across Pakistan
Dangerous Amazon catfish sightings in Pakistan have raised serious environmental concerns as experts warn the invasive species could damage native aquatic ecosystems and local fisheries.
According to WWF Pakistan the Amazon sailfin catfish was recently spotted at Karachi Fish Harbor while another specimen was recovered from a reservoir near Sukkur. Native to Latin America the species has now begun spreading rapidly across Sindh and parts of southern Punjab.
What Is the Dangerous Amazon catfish
The Amazon sailfin catfish is easily identified by its armored body covered in hard bony plates and its strong sail like dorsal fin.
Experts say the species is highly aggressive and competes directly with native fish for food and habitat. It also feeds on smaller fish spreads diseases and disrupts the natural balance of freshwater ecosystems.

Threat to Native Fish and Biodiversity
WWF Pakistan warned that the dangerous Amazon catfish is part of a growing list of invasive fish species now present in Pakistan.
“This species along with more than 25 non native fish introduced over the last three decades is displacing indigenous fish reducing biodiversity and threatening fishermen livelihoods,” WWF Pakistan stated.
Environmentalists fear that native fish populations could decline sharply if the spread continues unchecked.
Lessons From Past Invasive Species
Experts pointed to previous invasions such as tilapia in Manchar Lake and Keenjhar Lake which caused major declines in native fish stocks and overall fish production.
They warn that the impact of the Amazon sailfin catfish could be even more severe due to its rapid breeding and aggressive survival behavior.
Dangerous Amazon catfish : More Invasive Fish Detected
WWF Pakistan has also confirmed the presence of Red Bellied Pacu another invasive catfish species in the Chenab River and the Kandhkot area.
Authorities caution that once invasive fish establish themselves complete removal becomes extremely difficult and often impossible.
Call for Immediate Government Action
WWF Pakistan has urged strict monitoring and quarantine controls on imported non native fish species including the dangerous Amazon catfish.
The organization has called on the Ministry of Climate Change and other relevant departments to take urgent action to prevent further ecological damage.
Role of Illegal Import and Social Media
Experts highlighted that social media promotions of exotic fish seeds including Red Bellied Pacu and sailfin catfish have encouraged illegal import and farming.
Despite repeated warnings from environmental authorities these practices continue increasing the risk to Pakistan’s rivers lakes and reservoirs.
Dangerous Amazon catfish : Impact on Fishing Communities
The spread of invasive fish threatens not only biodiversity but also the economic stability of fishing communities that rely on native species for their livelihoods.
Declining fish stocks could result in reduced income higher food insecurity and long term damage to freshwater ecosystems.
Historical Context Invasive Species in Pakistan
Over the past few decades Pakistan’s freshwater systems have seen increasing pressure from invasive species due to weak regulation unmonitored imports and lack of public awareness.
Environmental experts stress that early intervention is critical to avoid irreversible damage.
Dangerous Amazon catfish : What Needs to Be Done
Specialists recommend:
Immediate bans on non native fish imports
- Public awareness campaigns
- Strong enforcement against illegal fish farming
- Long term monitoring of rivers and lakes
Without swift action experts warn Pakistan’s aquatic biodiversity could face irreversible losses.
