| Abstract | The relative growth contribution of natural and pelleted feed to Nile tilapia (Oreochromis niloticus) of mean initial size of 3-4 g was investigated. Four treatments were used as follows: Treatment 1, recirculating water system and pelleted feed; Treatment 2, static water system and pelleted feed; Treatment 3, static water system with seeded Microcystis aeruginosa as natural feed, and pelleted feed; Treatment 4, static water system with seeded Microcystis only. Natural feed led to a better growth response in terms of mean fish weight, mean growth rate and mean specific growth in smaller fish than in bigger ones. Pelleted feed led to best overall growth responses of fish during this experiment but the growth rate was lower when fed pellets compared to natural food during the early part of the experiment when fish were small . The pelleted feed led to better growth in the recirculating water than in the static water system. |
