Abstract: An experiment of 45 days was conducted to perceive the acceptability of different feed ingredients via Tor tor (Hamilton, 1822) fingerlings in earthen pond. The protein content of the ingredients Rice bran (RB), Mustard Oil cake (MOC), Floating feed and fish meal is recorded as 14%, 30%, 32%, and 45% respectively. These all feed stuffs are formulated as EFI (RB+MOC), EFII (RB+FF) and EFIII (RB+FM). Three experimental ponds uniform sizes of rectangular earthen ponds (20 × 10 × 1.5) meters with triplicate replication was conducted. Tor tor fingerlings were collected from Narmada River at Dongarwara ghat in the Hoshangabad. Experiment was started with few days’ old fingerling having an average length Pond 1 (EF1) 7.01, (EF2) 6.23, (EF3), Pond 2 (EF1) 6.64, (EF2) 7.00, (EF3) 6.62 and Pond 3 (EF1) 6.50, (EF2) 6.96, (EF3) 6.85cm respectively and average weight Pond 1 (EF1) 3.93, (EF2) 3.55, (EF3) 4.06, Pond 2 (EF1) 3.53, (EF2) 3.88, (EF3) 3.72and Pond 3 (EF1) 3.24, (EF2) 4.00, (EF3) 4.09gm of respectively. 70 fishes were initially stocked. During the experiment acceptability of feed was recorded lowest during initial 03 days. Average acceptability was recorded starting 3 day with EF1 (10-12.5%), EF2 (14-15%) and EF3 (17-20%). Acceptability increased during the last 15 days it was highest with maximum acceptability of EF3 (96-97 %). The acceptability of fish meal was found to be highest as compared to others.
