Municipal workers in Jakarta are conducting a large-scale operation to eradicate the invasive 'janitor fish' from the city's rivers, canals, and water reservoirs. The fish, known for their ability to survive in polluted waters, have exploded in population, threatening local biodiversity and clogging infrastructure.
Mass Removal Campaign Underway
On Friday, April 24, 2026, crews were seen killing and burying the caught fish as part of a coordinated effort to control the species. The operation involves multiple agencies and aims to reduce the fish's impact on Jakarta's already strained water systems.
Environmental Concerns
Experts warn that the janitor fish, which can grow up to 50 centimeters, outcompetes native species for food and habitat. Their burrowing behavior also damages riverbanks and increases sedimentation. The removal campaign is seen as critical to preserving the ecological balance of Jakarta's aquatic environments.
Authorities are exploring long-term solutions, including biological controls and public awareness campaigns to prevent further spread. The current operation is expected to continue for several weeks, with workers deploying nets and traps to capture the invasive species.
