Lake Tana is the source of the Blue Nile and is the largest lake in Ethiopia. Located in Amhara Region in the north-western Ethiopian Highlands, the lake is approximately 84 kilometres long and 66 kilometres wide, with a maximum depth of 15 metres, and an elevation of 1,788 metres. Lake Tana is fed by the Lesser Abay, Reb and Gumara rivers. Its surface area ranges from 3,000 to 3,500 square kilometres, depending on season and rainfall. The lake level has been regulated since the construction of the control weir where the lake discharges into the Blue Nile. This controls the flow to the Blue Nile Falls and hydro-power station.
Cypriniformes is an order of ray-finned fish, including the carps, minnows, loaches, and relatives. This order contains 11 or 12 families, over 400 genera, and more than 4,250 species, with new species being described every few months or so, and new genera being recognized frequently. They are most diverse in southeastern Asia, and are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.
The ǂNūǃarib (Senqu) "Black River", IGqili, or Orange River is a river in Southern Africa. It is the longest river within the borders of Lesotho and the Orange River Basin extends extensively into South Africa, Namibia and Botswana to the north. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean. The river forms part of the international borders between South Africa and Namibia and between South Africa and Lesotho, as well as several provincial borders within South Africa. Except for Upington, it does not pass through any major cities. The Orange River plays an important role in the South African economy by providing water for irrigation and hydroelectric power. The river was named the Orange River in honour of the Dutch ruling family, the House of Orange, by the Dutch explorer Robert Jacob Gordon. Other names include simply the word for river, in Khoekhoegowab orthography written as !Garib, which is rendered in Afrikaans as Gariep River with the intrusion of a velar fricative in place of the alveolar click, Groote River or Senqu River, derived from ǂNū "Black".
Mittry Lake is located in the Mittry Lake Wildlife Area, just north of Yuma, Arizona, on the Lower Colorado River. It is located in between the upstream Imperial Dam and the downstream Laguna Dam. Mittry Lake comprises about 750 acres (300 ha), with much of the shoreline covered with cattails and bullrush. The lake has undergone rehabilitation work including marsh dredging, revegetation and fish habitat improvement, making it a great location for small game hunting and sport fishing. It is public land managed by the Arizona Game and Fish Department, the Bureau of Reclamation and the Bureau of Land Management, and available to the public for recreational purposes.
The Iguazu River is a river in Brazil and Argentina. It is an important tributary of the Paraná River. The Iguazu River is 1,320 kilometres (820 mi) long, with a drainage basin of 62,000 square kilometres (24,000 sq mi).
The blue catfish is the largest species of North American catfish, reaching a length of 165 cm (65 in) and a weight of 68 kg (150 lb). The typical length is about 25–46 in (64–117 cm). The fish can live to 20 years. The native distribution of blue catfish is primarily in the Mississippi River drainage, including the Missouri, Ohio, Tennessee, and Arkansas Rivers, and the Rio Grande, and south along the Gulf Coast to Belize and Guatemala. These large catfish have also been introduced in a number of reservoirs and rivers, notably the Santee Cooper lakes of Lake Marion and Lake Moultrie in South Carolina, the James River in Virginia, Powerton Lake in Pekin, Illinois, and Springfield Lake in Springfield, Illinois. This fish is also found in some lakes in Florida. The fish is considered an invasive pest in some areas, particularly the Chesapeake Bay. Blue catfish can tolerate brackish water, thus can colonize along inland waterways of coastal regions.
Catla, also known as the major South Asian carp, is an economically important South Asian freshwater fish in the carp family Cyprinidae.

The Thamirabarani or Tamraparni or Porunai is a perennial river that originates from the Agastyarkoodam peak of Pothigai hills of the Western Ghats, above Papanasam in the Ambasamudram taluk.

It was called the Tamraparni River in the pre-classical period, a name it lent to the island of Sri Lanka. The old Tamil name of the river is Porunai. From the source to sea, the river is about 128 kilometres (80 mi) long and is the only perennial river in South India. This river flows towards north direction initially. However, it changes to east direction later.
The giant barb, Siamese giant carp, or simply Siamese carp, is the largest species of cyprinid in the world. These migratory fish are found only in the Mae Klong, Mekong, and Chao Phraya River basins in Indochina. Populations have declined drastically due to habitat loss and overfishing, and the giant barb is now considered critically endangered.
The sharptooth houndshark, or spotted gully shark is a species of houndshark in the family Triakidae found in shallow inshore waters from southern Angola to South Africa. Favoring sandy areas near rocky reefs and gullies, it is an active-swimming species that usually stays close to the bottom. This robust shark reaches 1.7 m (5.6 ft) in length and has characteristically large, rounded fins; the pectoral fins in particular are broad and sickle-shaped in adults. It also has a short, blunt snout and long furrows around its mouth. This species is gray or bronze in color above, with variable amounts of black spotting.

Clarias gariepinus or African sharptooth catfish is a species of catfish of the family Clariidae, the airbreathing catfishes.
The fishing industry in the land-locked country of Laos is a major source of sustenance and food security to its people dwelling near rivers, reservoirs and ponds. Apart from wild capture fisheries, which is a major component of fish production, aquaculture and stocking are significant developments in the country. Historically, fishing activity was recorded in writings on the gate and walls of the Wat Xieng Thong in Luang Prabang dated 1560. For many Laotians, freshwater fish are the principal source of protein. The percentage of people involved in regular fishing activity is very small, only near major rivers or reservoirs, as for most of the fishers it is a part-time activity.
