The trout barb, or Indian trout (Raiamas bola) is a carp of the family Cyprinidae, which occurs in freshwaters around the Bay of Bengal.
The trout barb has an elongated, slender body which is laterally compressed with a sharp snout. The juvenile fish possess a pair of rudimentary maxillary barbels but these are absent in the adults. It has very small scales and has 85-95 scales along its lateral line. It has a forked tail. The dorsal part of the body is greenish black, separated from the silvery flanks by a golden stripe running along the length of the body. The fins are yellowish in colour and there are a number of greenish blue spots on the body. [3]
The maximum length is 35 cm and they grow up to 2.3 kg in weight. [4]
The trout barb is found in the Indian states of Haryana, Himachal Pradesh, Uttar Pradesh, Bihar, Assam, Arunachal Pradesh, West Bengal and Orissa. It also occurs in Bangladesh, Nepal and Myanmar. Trout barbs were introduced into two lakes near Pune in 1926, where they subsequently successfully bred. [1]
The trout barb is found in rivers and streams [4] and also in ditches and canals. [3] In India it prefers clear streams with rocky riverbeds. [1] It breeds during early monsoon season, in June, spawning in heavily flooded areas. [3] It is sexually mature at around three years old, [1] during the spawning seasons the males become brighter and the skin on their flanks becomes rougher. The wide mouth and stream-lined body are adaptations for an actively predatory lifestyle. [1]
The trout barb is listed as Least Concern by the IUCN but the population is thought to be declining due to illegal and destructive fishing methods. [1]
The trout barb is said to have a delicate flavoured flesh and to make good sport for fly fishermen. [3]
The roach, or rutilus roach, also known as the common roach, is a fresh- and brackish-water fish of the family Cyprinidae, native to most of Europe and western Asia. Fish called roach can be any species of the genera Rutilus, Leucos and Hesperoleucus, depending on locality. The plural of the term is also roach.
The Indian flying barb, historically flying barb, is one of the species known in the group flying barbs owing to their extremely long barbels. It was discovered as long ago as 1822 by Hamilton. However, it is rarely seen in aquaria. It is found in Myanmar, Nepal, Pakistan, Sri Lanka and India, it is found in many of the same localities as Danio rerio and Danio dangila, an example being the Jorai Rivulet, a tributary of the Sankosh river in Coochbehar district, West Bengal, India. The rare fish Borellius spp. is locally named "Boirali maach". In Nepalese Terai it is called Dedhawa.
Barbodes binotatus, commonly known as the spotted barb or common barb, is a tropical species of cyprinid fish endemic to Java, Indonesia.
The Titicaca orestias, Lake Titicaca orestias, or Lake Titicaca flat-headed fish, also known by its native name amanto, is a likely extinct freshwater killifish from Lake Titicaca in South America. It belongs in the pupfish genus Orestias, endemic to lakes, rivers and streams in the Andean highlands. With a total length of up to 27 cm (10.6 in), it was the largest member in that genus. In the hope that an undiscovered population remains, it is listed as Data Deficient by the IUCN. Despite its common name, it is not the only Orestias from Lake Titicaca.
Tor khudree, the Deccan mahseer, Khudree mahseer, or black mahseer, is a freshwater fish of the carp family found in major rivers and reservoirs of India and Sri Lanka. Found throughout India, following large-scale introductions of artificially-bred fish across the country, but found of the largest size and in the greatest abundance in mountain or rocky streams.
The fish as originally described by Sykes in his November 1838 paper 'On the Fishes of the Dukhun' as Barbus khudree, is a silvery-bluish coloured fish, with blood red fins or fins tipped with a bluish tinge. The type locality is the Mula-Mutha River close to the Indian city of Pune, a part of the Krishna River basin.
Although there have been efforts to artificially breed this mahseer since the early1970's, there is no way to determine if these fish are Tor khudree, as the populations within the type locality have gone extinct.
The orange-spotted grouper, also known as the brown-spotted rockcod, estuary cod, estuary rockcod, goldspotted rockcod, greasy cod, North-west groper, orange spotted cod or blue-and-yellow grouper, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It has an Indo-Pacific distribution and is found in marine and brackish waters.
The Christmas wrasse, also known as the ladder wrasse, green-barred wrasse or green-blocked wrasse, is a species of ray-finned fish, a wrasse from the family Labridae which is native to the Indian Ocean and the western Pacific Ocean. It inhabits shallow reefs at depths from the surface to 10 m (33 ft). It is of minor importance to local commercial fisheries and can be found in the aquarium trade.
The Kuria labeo is a species of fish in the carp family, Cyprinidae. It is native to Pakistan, India, Bangladesh, and Burma, and it is known from Afghanistan and Nepal.
Raiamas senegalensis is a species of cyprinid fish in the genus Raiamas from western Africa east to the River Nile. It sometimes is found in the aquarium trade.

The rice-paddy eel is an eel in the family Ophichthidae. It was described by Francis Buchanan-Hamilton in 1822, originally in the genus Ophisurus. It is a tropical, marine eel which is known from the Indo-West Pacific, including Somalia, Tanzania, South Africa, India, Pakistan, Sri Lanka, Indonesia, Polynesia, Australia, Bangladesh, Cambodia, Kenya, Madagascar, the Philippines, Malaysia, Mozambique, Seychelles, Saudi Arabia, Taiwan, China, Thailand, Vietnam, and southern Yemen. It is an anadromous species and spawns in freshwater, often in rice paddies during the rainy season, earning it its common name. It also spends time in lagoons, estuaries and coastal rivers, in which it lives in burrows in the river bottom and bank. Males can reach a maximum total length (TL) of 100 centimetres, but more commonly reach a TL of 70 cm.
