Abstract
This study was carried out to evaluate the effect of floating and sinking pellets on growth performance of common carp (Cyprinus carpio). Triplicate groups of 624 carp (average  initial weight 175 g) were stocked in 6 round concrete pond with a density 1/8 kg/m3 and fed to apparent satiation, 4 times a day with interval of 4 h for 75 days. The growth rate of fish was estimated by feeding the extruded and pellet feeds 122.63 and 77.43g respectively. Fish were fed from two type of feed in this culture system had a high survival rate (97-99.5%). Thus, high survival rate of carp in concrete ponds indicate its easy adaptation to new cultural conditions. The results showed that growth and nutrition parametrs included in:weight gain (WG%), specific growth rate (SGR), protein efficiency ratio (PER) increased and food conversion ratio (FCR) decreased significantly when they were fed on floating pellets compared with the fish fed on sinking pellets (p<0/05). Thus, the results showed that carp, despite the oral form and feeding habits of the bed, can easily feed on the floating pellets and have better growth performance.
