Abstract: An experiment of one and half month was conducted to perceive the growth performance and survivability of Ompok pabda (Hamilton, 1822) fingerlings in earthen pond fed with different feed ingredients. These were four distinct types of feed ingredients with different percent of protein content in rice bran (RB) 14%, mustard oil cake (MOC) 30%, Floating feed (FF) 32% and fish meal (FM) 45% respectively. These all feed stuffs are formulated as EF-I (RB+MOC), EF-II (RB+FF) and EF-III (RB+FM) Three experimental ponds with uniform sizes of rectangular earthen ponds (20 × 10 × 1.5) meters with triplicate replication was conducted. Ompok pabda experiment was started with few old days’ fingerling having an average weight and length of (1.609 gm) and (6.85cm) respectively. 70 fishes were initially stocked. The highest gain in weight P3C (9.20gm), P1C (6.70gm) & P2C (5.40gm), Length P1C (9.8cm), (P3C 8.8cm) & (P2 8.6cm), Average Daily Weight Gain P3C( 0.175), P1C (0.692) & P2C (0.062), Specific Growth Rate P3C (2.102), P1C (1.731) & P21 (1.114), and Survivability of fishes P1C (97%), P3B (82%) & P3A (97%) And lowest Food Conversion Rate after experiment was P3B (0.488), P1C (0.692) & P2C (1.378) respectively. Beside this, the water quality parameters showed most of the fluctuations in phosphate level in water as compared to pH, Ammonia, Temperature, Dissolve oxygen and others. The result implies that fish has better growth performance and survivability with EF-III firstly and secondly in EF-I as compare to EF-II respectively.
