In recent years, various investigators have given considerable attention to the propagation of seriously endangered mahseer in the Himalayan waters (Badola and Singh 1984, Shrestha 1986, 1988, 1990, Nautial and Lal 1988, Das 1990). They have been prompted by several considerations among them are: (i) loss of natural habitat and endangering breeding population; (ii) overfishing in natural waters and pollution and destruction spawning ground and brood fish; (iii) scarcity of healthy brood fish for artificial breeding by hormone injection; (iv) recognition by cold water fish culturists of a need for propagating mahseer in lakes and reservoirs to boost recreational fisheries; and (v) the realization that the mahseer may be ranched so that wild population be built in natural waters.
