New Fish Species Discovered in Sukhna Lake

Researchers from Panjab University's zoology department have identified six new fish species in Sukhna lake, marking a significant addition to its known biodiversity. These species were not recorded in previous surveys conducted in 2005-2006 and 2012-2014. The latest evaluation, conducted between October 2025 and October 2026, documented 25 fish species from 289 samples.

This scientific endeavor also revealed concerning trends, including the illegal dumping of exotic aquarium fish like goldfish and Nile tilapia, posing a threat to native aquatic life. The study noted that some fish species are 'vulnerable' or 'near threatened' according to IUCN classifications. Furthermore, microbiological examinations detected bacteria in three fish specimens, underscoring the need for disease surveillance to prevent potential entry into the human food chain.

Sukhna lake's ecological importance has been further recognized with its inclusion in the Ramsar List of Wetlands of International Importance. The Ramsar Information Sheet highlights the lake's critical role as a refuge for fish species during periods of hydrological stress and elevated temperatures, supporting their migration, spawning, and survival.
