Lower Jhelum Hydroelectric project under the programme of Uri hydroelectric power project Baramulla J & K, was commissioned three decades ago on River Jhelum. At this segment of river, 18 species of fishes have been recorded. After the commissioning of this project several deteriorative environmental effects have been noticed on the aquatic biodiversity of this river. This project exerted highly adverse effects on the population of mighty Mahaseer, Tor putitora (Golden Mahseer), which flourished a lot in the past but diminished so much so that it has come under endangered category of fish species. As such Schizothorax plagiostomus, S. curvifrons, S. esocinus, S. labiatus are also affected adversely and now are scarce in catches. Two major factors may be considered responsible for the dwindling population of above mentioned species of fishes first bunding of river and practically negligible provision of fish ways/fish ladders which has created obstacle in free movement of fishes for searching food and breeding grounds and secondly the alterations in the ecological feature of the region.
