Preliminary feeding trials on juveniles of golden mahseer, Tor putitora (Ham.) at different stocking densities with artificial dry pellet feeds

Abstract

For scientifically managed culture techniques and maximizing the production of healthy stocking material of depletingHimalayan mahseer, 6 artificial feeds were formulated and compounded. The feeding experiments were conducted on hatcheryreared hatchlings, advance fry and fingerlings and also on the juveniles of this species collected from wild waters.Artficial feeds of 21.4-50.2% protein levels revealed a better growth and high survival having 45.4% crude protein. Apositive correlation was observed between the dietary protein content and the overall performance of the conversion ration.Impact of different densities for the better culture performance in various juvenile stages have also been worked out. Thepresent communication reviews the practice of conventional diets and scope of nutritional manipulation of present testedpractical diets to evolve cost-effetive strategies for taking mahseer for aquaculture.
