Schizopyge is a genus of cyprinid freshwater fish found in Pakistan and the northwestern part of India. [1] [2] [3] Schizopyge is closely related to Schizothorax and some species have historically been moved between the two genera. [4]

Pakistan federal parliamentary constitutional republic in South Asia

Pakistan, officially the Islamic Republic of Pakistan, is a country in South Asia. It is the world’s sixth-most populous country with a population exceeding 212,742,631 people. In area, it is the 33rd-largest country, spanning 881,913 square kilometres. Pakistan has a 1,046-kilometre (650-mile) coastline along the Arabian Sea and Gulf of Oman in the south and is bordered by India to the east, Afghanistan to the west, Iran to the southwest, and China in the far northeast. It is separated narrowly from Tajikistan by Afghanistan's Wakhan Corridor in the northwest, and also shares a maritime border with Oman.

India Country in South Asia

India, also known as the Republic of India, is a country in South Asia. It is the seventh largest country by area and with more than 1.3 billion people, it is the second most populous country as well as the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives, while its Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia.

<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. 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.

Species

There are currently two recognized species in this genus: [1]

Schizopyge dainellii is a species of cyprinid freshwater fish found in the Indus basin in Pakistan.

Decio Vinciguerra was an Italian physician and ichthyologist who for many years was Director of the Aquarium of Rome.

Schizopyge niger, the Alghad snowtrout, is a species of cyprinid freshwater fish that lives in cold lakes and nearby channels in the Kashmir region in India and Pakistan. It reaches up to about 33 cm (13 in) in standard length.

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 the Indian state of Jammu and Kashmir. 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>Diptychus</i> genus of cyprinid fish

Diptychus is a genus of cyprinid freshwater fish, consisting of two species found in Himalaya and the Tibetan Plateau of China, India, Nepal and Pakistan, ranging west to the Tien Shan Mountains and Central Asia. The type species is the scaly osman, Diptychus maculatus. The name is derived from the Greek word di, meaning "two", and the Greek word ptyx, meaning "fold". Diptychus is up to 70 cm (2.3 ft) in total length.

A snowtrout is any of a number of ray-finned fishes from the Himalayas region. These cyprinids resemble the very distantly related trouts in habitus due to convergent evolution.

Common snowtrout species of fish

The common snowtrout or snowtrout is a species of ray-finned fish in the genus Schizothorax. It is found in the Himalayan region of India, Bhutan, Nepal, Pakistan, and Afghanistan. It lives in mountain rivers among rocks, feeding on algae, aquatic plants and detritus, they breed in April and May. They are much sought after as a food fish. It is threatened by a number of factors including overfishing, pollution, the damming of rivers and the introduction of exotic fish, particularly salmonids and the population is declining.

Enteromius baudoni is a species of tropical cyprinid freshwater fish from Central and Western Africa. It is found in western Africa, in the river basins of the Chad Basin, the Volta basin, the Niger River basin, the Gambia River basin, the Senegal River basin, the Sassandra River basin, and the Bandama River basin. In central Africa, it is found in the Ubangui River ecosystem. It typically inhabits tropical freshwater ecosystems between 24 and 26 °C. It was originally described by Belgian-British zoologist George Albert Boulenger as Barbus baudoni in 1918, and the holotype, collected from Bangui, Central African Republic, is stored at the Muséum national d’Histoire naturelle in Paris. The species was originally classified in the Barbus genus, but was reclassified as belonging to the Enteromius genus in 2015 after examining extensive taxon, geographical, and genomic sampling of the species in the family Cyprinidae.
