Invasive American catfish found in Bihar’s Aruna River, sparks ecological concerns

Fishermen in Bihar’s Motihari district caught five American catfish in the Aruna River, located along the India-Nepal border. The species, native to the Amazon River in South America, is a known predator that feeds on other fish. Local youths fishing in the river first spotted the unusual catch, and the discovery quickly attracted crowds. The presence of this foreign species has raised concerns among residents about its potential impact on the river’s aquatic life.

Experts note that the American catfish, which can outcompete native species for food and habitat, has been reported in various regions due to accidental or deliberate introduction. While it remains unclear how the fish entered the Aruna River, similar cases in other parts of India have been linked to illegal fish farming, aquarium releases, or cross-border water movements. Local authorities have yet to comment on whether any official assessment or containment measures will be taken regarding the presence of the species.

Residents have urged officials to investigate and monitor the river to prevent potential ecological disruption. The discovery has led to discussions on regulating the introduction of non-native species in Indian water bodies. Fisheries and environmental experts emphasize the importance of maintaining biodiversity and ensuring that invasive species do not threaten local aquatic ecosystems.
