| Summary, etc. | This study was designed to compare the performance of different fertilizers and feeding strategies as nutritional input options in fish farms. Twelve earthen ponds 1000 m2 each were assigned randomly into four treatments, with triplicates per treatment. The four fertilization treatments were: compost (T 1); cow manure (T 2); compost and urea plus superphosphate (T 3); and cow manure and urea plus superphosphate (T4). Trial ponds stocked with mixed sex Wapia fry (0.15 g) at stocking rate 2 fish/m', and silver carp stocked for maintaining water quality, at rate of 0.025 fish/m'. Ali treatment feed artificial feed 25% at 2% body weight from week twelve to end of trial. Mixed fertilizers treatments (T 3 and T 4) achieved significantly higher (P<0.05) fish yield than organic fertilizers treatments (T 1 and T 2). Total fish yield in decreasing order was T 4, T 3, T 2 and T 1 (1559.3, 1539.3, 1402.7 and 13% kg/fed/year, respectively. Feed intake and feed effidency parameters FE%; PER; PPV% were significantly higher in mixed fertilizers (T 3 and T 4) than organic fertilizers treatments (T 1 and T 2). Of water quality (WQ) parameters only available phosphorus was significantly higher in compoSt only treatment compared to the other treatments. While the other WQ parameter (DO. pH, NO" N~, NH3, total alkalinity, and hardness) were not significantly differ among treatments. Partial economic analysis showed that benefit cost ratio was significantly hi9her (P<0.01) in T 3 (54%) and T 4 (49 %) compared to T 1 (36.4%) and T 2 (25.8%). The result of this experiment conduded that feeding strategy using mixed fertilizers and supplementary feed as feeding strategy perfonmed better than organic fertilizers and supplementary feed, increased fish yield and farm revenue. |
