Three types of formulated pellets having 30%, 40%, 50% crude protein (P.30, P.40, P.50) respectively, along with a commercial control feed (con. P.30) were used to determine their suitability as feed for Macrobrachium rosenbergii broodstock. For all the three formulated pellets linear programming models were applied to determine the optimum level of the ingredients which ensures minimum cost. The study was undertaken using 12 one-tonne-capacity fiberglass tanks, each having a water recycling system. Each tank was partitioned into ten equal compartments and each compartment was stocked with 1 male and 1 female prawn fed at 8.00, 12.00 and 18.00 hrs daily at 2% of their body weight. Sampling was conducted two months later to determine the fecundity and biochemical content of the eggs and muscles. The result indicated that P.40 attained the highest fecundity having 1354.2 eggs/g body weight, followed by P.30 (1320.4 eggs/g body weight), con P.30 (1068.9 eggs/g body weight) and P.50 (1032.75 eggs/g body weight). However, statistically no significant difference was observed between P.30 and P.40 pellets therefore, considering the cost factor, P.30 pellet is recommended as the broodstock feed for Macrobrachium rosenbergii.
