Tor tambroides, known as empurau in Malay, is a species of mahseer native to Southeast Asia.

Contents

Taxonomy

It has been suggested that the species represents a junior synonym of Tor tambra . [2] [3] T. tambra, T. tambroides and T. douronensis may be synonymous. [4]

Distribution

These fish have been found throughout Southeast Asia, ranging from Thailand in the Chao Phraya and Mekong River basins to the Greater Sunda Islands. The species has been reported in Burma. [5] The type locality of Tor tambroides is the Indonesian island of Sumatra.

Ecology

The species is omnivorous, sometimes eating toxic fruits when the streams it inhabits flood the forest; this may make them temporarily inedible. During the rainy season, juveniles migrate downstream. After 2 months, matured adults travel back upstream to spawn at the headwaters in the dry season. [5]

Conservation

While the species is not currently assigned a conservation status by the IUCN due to lack of data, overfishing is assumed to threaten the wild population. [1] The empurau, as the species is known in Malaysia, is reportedly the most expensive edible fish in the country [6] and has been known to fetch up to RM1800 per kilogram of the fish. [7]

Aquaculture

Empurau can be grown in captivity. The fish require moving, well-oxygenated water. They should be fed on various fruits and seeds to simulate their natural diet. [8] Artificial hormones may be necessary to induce reproduction. [9]

<i>Tor</i> (fish) Genus of fishes

Tor is a genus of freshwater ray-finned fishes belonging to the family Cyprinidae, the family which includes the carps, barbs and related fishes. The fishes in this genus, and some related genera, are commonly known as mahseers. These fishes are found in Asia.

<span class="mw-page-title-main">Mahseer</span> Common name for several genera of carp

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.

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.

<i>Tor khudree</i> Species of fish

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.

It was reported to be found in the Salween river, the natural border between Thailand and Myanmar as well, but the number is very rare, only three times in 28 years.

This fish has been attributed to Valenciennes however, in his original notes, he claims that the fish he described "formed part of the collection made in Java by Kuhl and Van Hesselt; they named it Dourr." Certainly, the type locality is Java, in Indonesia and the holotype is lodged at Bogor Zoology Museum.
