Effects of feeding frequency on growth, survival and water quality of rearing tanks of the Indian white shrimp (Penaeus indicus)

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
