Mahseer is the common name used for the genera Tor, Neolissochilus, Naziritor and Parator in the family Cyprinidae (carps). The name is, however, more often restricted to members of the genus Tor. The range of these fish is from Vietnam in the east and China in the north, through Laos, Cambodia, Thailand, Malaysia, Brunei and Indonesia, and across southern Asia including the countries of India, Nepal, Bhutan and Bangladesh within the Indian Peninsula, plus Sri Lanka, Pakistan and Afghanistan. They are commercially important game fish, as well as highly esteemed food fish. Mahseer fetch high market price, and are potential candidate species for aquaculture. Several of the larger species have suffered severe declines, and are now considered threatened due to pollution, habitat loss, overfishing and increasing concern about the impacts of unregulated release of artificially bred stock of a very limited number of species.

It is the most species-rich and widely distributed genus in the family with new species being discovered on a regular basis. These species are distributed in the Black Sea basin, northern Turkey, south and east to the Yangtze River drainage in China and south throughout Indo-China to Java, Indonesia. They are found in Asia Minor and southwards to Southeast Asia. The genus is very diverse in the Indian subcontinent. Southeast Asian species tend to have restricted distributions.

Osteobrama belangeri is a species of ray-finned fish in the genus Osteobrama. It was found in the Indian state of Manipur, but has been extirpated there and as of 2022 is found in the wild only in Myanmar. Farmed populations in Manipur and wild-caught fish from in Myanmar are used as food. The extirpation from Manipur was caused by dam building, habitat degradation and the introduction of alien species which caused the populations to fragment.
Osteobrama bhimensis is a species of ray-finned fish in the genus Osteobrama. Osteobrama bhimensis is a synonym of Osteobrama vigorsii but valid on its own according to Fishbase.
Osteobrama cotio is a species of ray-finned fish in the genus Osteobrama. This species had three subspecies named O. cotio cotio, O. cotio cunma and O. cotio peninsularis but these are now considered separate species. This species is found in the drainage basins of the Ganges-Brahmaputra including Jiri River in Manipur, Barak River in Silchar, in Brahmaputra River, Uzan Bazaar in Assam, and in Bihar, Madhya Pradesh, Uttar Pradesh, and Punjab in India, and in Bangladesh. The presence of O. cotio in southern India and from the Indus basin of India and Pakistan needs to be confirmed. This species is threatened by extensive loss of habitat caused by pollution and deforestation.
Osteobrama vigorsii is a species of ray-finned fish in the genus Osteobrama. It is known to occur in the states of Andhra Pradesh, Chhattisgarh, Karnataka, Madhya Pradesh, Maharashtra and Orissa in the drainage systems of the Krishna, Godavari and Mahanadi. It is found in fast flowing streams and rivers as well as reservoirs. It attains a total length of 30 cm and its prey is smaller fish and insects.

Hipposcarus is a genus of marine ray-finned fishes, parrotfish from the family Scaridae. The two species in the genus are distributed in the Indo-Pacific. .
Crenidens is a small genus of three species of seabream from the family Sparidae from the western Indian Ocean. It was previously regarded as monotypic, with the sole species being the Karenteen sea bream Crenidens crenidens but two other species are now accepted as valid species, separate from the type species, C. crenidens.
Osteobrama cunma is a species of freshwater ray-finned fish from the carp and minnow family, the Cyprinidae. It occurs in the drainage of the River Chindwin in Manipur, India and Myanmar. It was formerly considered a subspecies of the more widespread Osteobrama cotio.
Osteobrama peninsularis is a species of freshwater ray-finned fish from the carp and minnow family, the Cyprinidae. It occurs in the Indian states of Andhra Pradesh, Karnataka, Maharashtra and Kerala. It has been recorded from the drainages of the Krishna River and the Godavari River as well as the Periyar River. Formerly this taxon was confused with Osteobrama cunma and this means that its distribution is uncertain, although it is described as common in Pune and the surrounding areas and in Karnataka. Like O. cunma it was formerly treated as a subspecies of Osteobrama cotio.
Histiophryne pogonia is a species of fish in the family Antennariidae. It is native to the Pacific Ocean, where it is known from Indonesia and the Philippines, specifically the shallow inshore waters of Lombok, Komodo, and possibly Cebu. It is a reef-dwelling species that is thought to be more active at night. Males of the species reach 4.8 cm SL, whereas females are slightly larger at up to 5.4 cm SL. Two specimens of H. pogonia were observed to live peacefully in an aquarium for multiple months, which suggests that this species may be less aggressive and less cannibalistic than members of genera such as Antennarius or Histrio. This species can be distinguished from its congeners by its extremely small illicium, although it does have a distinct esca unlike members of the genus Echinophryne. While it was initially described as H. pogonius, FishBase and WoRMS list it as H. pogonia, with FishBase marking H. pogonius as a misspelling.
Canthigaster aziz, known as Aziz's toby is a species of pufferfish in the family Tetraodontidae. It was described in 2020 by Keiichi Matsuura, Sergey V. Bogorodsky, Ahmad O. Mal, and Tilman J. Alpermann based on a single specimen collected from the northern Red Sea off of Saudi Arabia. It was trawled from a depth of 315 m (1033 ft), which is reportedly the second highest depth at which any fish of the genus Canthigaster has been collected. The only known specimen measures 2 cm SL. The species was named after the King Abdulaziz University. It is thought to have been collected over a hard substrate as the trawling gear used to collect it was severely damaged during operation.
Mustura is a genus of fish in the family Nemacheilidae found in Myanmar.
