Popis: The effects of feeding frequency on growth performance, feed conversion ratio and survival of post-larvae Indian white shrimp, Penaeus indicus were evaluated in a 56-day study. The study was conducted in sixteen fiberglass tanks provided with aerated recirculating water with four replicate tanks for each treatment. Twenty post larvae with a mean weight of 1.56 0.02g were hand-counted and stocked into each of the replicate tanks and fed 2, 4, 6 and 8 times a day, respectively. Final body weights were measured significantly lower at 2 and 4 times/day (5.76 0.08 and 5.96±0.15g, respectively) than 6 and 8 times/day (8.54±0.16 and 8.31 0.19g, respectively) treatments (P
