Systematik

Mahseer is the common name used for the genera Tor, Neolissochilus, and Naziritor in the family Cyprinidae (carps). Sen and Jayaram (1982) reviewed the literature on Mahseer in India and restricted the term 'Mahseer' to members of the genus Tor. They range from Malaysia, Indonesia, across southern Asia to Pakistan, including the Indian Peninsula (Menon, 1992; Roberts, 1999; Mohindra et al., 2007). 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 (Ogale, 2002). Several of the larger species have suffered severe declines, and are now considered threatened due to pollution, habitat loss and overfishing.

The taxonomy of the mahseers is confusing due to the morphological variations they exhibit. In developing strategies for aquaculture and propagation assisted rehabilitation of mahseer species, there is a need to resolve taxonomic ambiguities (Mohindra et al., 2007).

Mahseers inhabit both rivers and lakes, ascending to rapid streams with rocky bottoms for breeding. Like other types of carps, they are omnivorous, eating not only algae, crustaceans, insects, frogs, and other fish, but also fruits that fall from trees overhead.

The first species from this group were scientifically described by Francis Buchanan-Hamilton in 1822, and first mentioned as an angling challenge by the Oriental Sporting Magazine in 1833, soon becoming a favorite quarry of British anglers living in India. The golden mahseer has been known to reach 2.75 m (9 ft) in length and 54 kg (118 lb) in weight, although specimens of this size are rarely seen nowadays. In addition to being caught for sport, mahseer are also part of commercial fishing and ornamental or aquarium fish.

Etymology[Bearbeiten | Quelltext bearbeiten]

The Hindi name of mahāsir, mahāser, or mahāsaulā is used for a number of fishes of the group. British anglers in India called them the Indian salmon. Several sources of the common name mahseer have been suggested: It has been said to be derived from Sanskrit, while other say it is derived from Indo-Persian, as it means tiger of waters (or alternatively big-head) in Persian. Alternatively, mahā-śalka, meaning large-scaled, as the scales are so large that Buchanan mentions that playing cards were made from them at Dacca. Mr. H. S. Thomas suggests mahā-āsya; great mouth.[1]

Species[Bearbeiten | Quelltext bearbeiten]

Sen and Jayaram (1982) reviewed the literature on Mahseer in India and restricted the term 'Mahseer' to members of the genus Tor. However, the few species of Genus Neolissochilus and two species of Genus Naziritor are also called as Mahseers due to their big size.
