Scientists from the Zoological Survey of India (ZSI) have discovered a new species of catfish, Glyptothorax senapatiensis , in the Chindwin river drainage in Senapati district of Manipur. The people of the region have been having the six-cm-long freshwater fish as food for long, calling it Ngapang.
“It is a small but edible fish with high nutritional value and a lot of oil content,” ZSI scientist Laishram Kosygin told The Hindu . The fish has a thoracic adhesive apparatus that helps it cling on to the rocky riverbed in mountains against strong currents. All Glyptothorax-genus fish have this characteristic.

Scientists say the Northeast has a rich aquatic biodiversity, with 361 of the 816 fish species found in India present there. Several important species of catfish, a diverse group of ray-finned fish with prominent barbells resembling cat whiskers, are found there.
Manipur has a high diversity of aquatic fauna because of the two important river drainage systems. “The western half is fed by the Barak-Brahmaputra drainage and the eastern and central valleys are crisscrossed by the Chindwin river drainage, and these account for the variety in the aquatic fauna,” Mr. Kosygin said.
