Biological invasion endangers Iraqi rivers

The spread of tilapia and African catfish in Iraqi waters has posed a major threat to the local fishery resources. These invasive species originate from North Africa and have entered Iraqi waters through unknown sources. It is believed that they migrated via aquaculture operations in Syria and Jordan. The tilapia has become widespread, while the African catfish poses an even greater risk because it preys on native fish populations in large quantities, potentially leading to the collapse of Iraq's biodiversity and its water resources. Currently, the situation is catastrophic, and controlling this biological invasion is difficult due to a lack of expertise. Although simple measures such as electric fishing or chemical treatment of the water exist, effective solutions require greater efforts.
