The National Green Tribunal reports a dominance of exotic fish species over indigenous ones in the Yamuna River, causing a decline in local varieties such as Indian Major Carps and Hilsa. The CIFRI suggests controlling illegal fishing and pollution while prohibiting exotic fish releases.

The National Green Tribunal has sounded an alarm over the domination of exotic fish species in the Yamuna River, leading to a steep decline in native fish populations. The green body was hearing the pressing concern of diminishing Indian fish varieties, a matter that had prompted an earlier response request from relevant authorities, including the Central Inland Fisheries Research Institute (CIFRI) in Prayagraj.

A tribunal bench, chaired by Justice Prakash Shrivastava and comprising Justice Arun Kumar Tyagi and expert member A Senthil Vel, noted CIFRI’s report highlighting the drastic reduction in fish species like Indian Major Carps, large catfishes, and Hilsa. Notably, the Labeo Catla species have shown a significant decline, hinting at acute habitat degradation in the river.

The report attributes the reduction to the proliferation of exotic species such as Common Carp and Nile tilapia. Recommendations from the tribunal include banning illegal fishing practices, enhancing monitoring, and preventing the release of exotic fish. A response is awaited from the Union ministries of Jal Shakti, Fisheries, and Animal Husbandry, with further proceedings slated for March.
