A Sailfin Catfish has reportedly been spotted in the Indus River near Sukkur, raising alarm among fishing communities and environmental experts.
Native to South America’s Amazon River, the Sailfin Catfish is known for its vibrant fins and shimmering scales. While popular in aquariums, its presence in natural water bodies has raised concerns about potential ecological disruption in Pakistan.
Environmental specialists warn that if Sailfin Catfish begin breeding in the wild, they could compete aggressively with native species for food, space, and breeding sites. “Valuable local fish could gradually disappear, creating long-term ecological problems,” said one expert.
However, experts also urge caution. Mohammad Moazam Khan, aquatic wildlife specialist at the World Wildlife Fund (WWF), emphasized that one or two sightings do not indicate an ecological disaster. “Not all exotic fish are invasive, and not every report is scientifically accurate,” Khan said.
He explained that Sailfin Catfish are mainly kept for aquarium decoration. The real risk occurs when people irresponsibly release them into rivers or streams. Evidence of breeding, rather than simple sightings, is what determines ecological impact.
Khan also pointed out examples of truly invasive species in Pakistan, such as red-bellied tilapia and pacu fish, which have demonstrated aggressive reproduction in natural water bodies. “Research and evidence must guide our response, not fear alone,” he added.
Pakistan’s aquarium trade currently operates with minimal oversight. Lack of import regulations and quarantine systems for exotic fish could allow species like Sailfin Catfish to establish populations in the wild.
The WWF stressed the importance of monitoring and public awareness. “We must avoid unscientific panic while also preventing irresponsible releases. Balanced policy, research, and education are key to protecting our rivers,” Khan said.
Sailfin Catfish sightings in Pakistan highlight the delicate balance between exotic pet ownership and environmental responsibility. Experts urge careful observation, reporting, and evidence-based action to safeguard native aquatic life.
