  1. Mean values within the same row sharing the same superscript are not significantly different (P ˃ 0.05), Citrus sinensis-free diet; n = 3 (three samples from each treatment), mean ± SD
  2. Initial length and weight were 3.91 ± 0.03 cm and 0.83 ± 0.06 respectively
  3. SR survival rate, LG length gain, WG weight gain, FI feed intake, SGR specific growth rate, FCR feed conversion ratio, PER protein efficiency ratio
