Abstract: An experiment was conducted to assess the efficacy of formulated diets and feeding strategies in brood stock management of Labeo rohita (Ham.). The experiment comprised of three factors i.e., two supplementary feeds (D1, routine diet vs. D2, diet supplemented with vitamin-mineral mixture @ 2%), two feeding rates (R1, 3% BW vs. R2 4% BW) and two feeding frequencies (F1, once-a-day vs. F2, twice-a-day feeding. There were 8 treatments regimes viz., T1 (D1, R1, F1), T2 (D1, R1, F2), T3 (D1, R2, F1), T4 (D1, R2, F2), T5 (D2, R1, F1), T6 (D2, R1, F2), T7 (D2, R2, F1), and T8 (D2, R2, F2). The yearlings of 12-16 months age were stocked at a density of 1,000 kg ha-1 (16 fish/ pond), fed for a period of 8 months and the effect of different treatments on survival and growth of fish was recorded. During the culture period, 100% survival of fish was recorded in all the treatments. At the end of culture period, total body length and body weight was higher in T8 (P<0.05) compared to other treatments. In addition, the percent total length growth and BW gain was maximum in T8. Furthermore, specific growth rate was higher in T8 (P<0.05) as compared to other treatments. All treatment groups had condition factor value of more than 1 indicated that the fishes were in good condition. It may be concluded that supplementary feed (with vitamin-mineral mixture), feeding rate (4% fish BW) and feeding frequency (twice-a-day) improved the growth of L. rohita brood stock.
