Wular Lake Lake in Jammu and Kashmir, India

Wular Lake is one of the largest fresh water lakes in Asia. It is sited in Bandipora district in Jammu and Kashmir, India. The lake basin was formed as a result of tectonic activity and is fed by the Jhelum River. The lake's size varies seasonally from 12 to 100 square miles. In addition, much of the lake has been drained as a result of willow plantations being built on the shore in the 1950s.

<i>Schizothorax</i> Genus of fishes

Schizothorax is a genus of cyprinid fish found in southern and western China, through northern South Asia (Himalaya) and Central Asia, to Iran, with a single species, S. prophylax, in Turkey. They are primarily found in highland rivers, streams and lakes, although a few species occur in lower-lying locations, like Lake Balkhash and lakes of the Sistan Basin. Their scientific name means "cloven-breast", from Ancient Greek schízeïn (σχίζειν) "to cleave" and thórax (θώραξ) "breast-plate". The western species are typically referred to as marinkas from their Russian name marinka (маринка), while the eastern species are usually called snowtrout. Although they do resemble trouts in habitus this is merely due to convergent evolution and they are by no means closely related apart from both being Teleostei: Cyprinids are in the teleost superorder Ostariophysi, while trouts are in the superorder Protacanthopterygii. Their ancestors must thus have diverged as early as the Triassic, more than 200 million years ago.
