Rearing of common carp (Cyprinus carpio) in fiber glass tanks with pellet feeding

The intensive culture of common carp (Cyprinus carpio) evaluated in fiberglass tanks(2*2m) with feeding on pellet during 8 weeks.The fish (n=201)of common carp selected from three treatments along with three replicates as the average of fish weight was less than 100(g )which divided into <50(g), 50-70(g) and 70-100(g).At the first experiment , there is no statistically significant difference between fish weight in relative to replicate treatment (P>0.05).The common pellet food was chosen for feeding from market as fish were fed by the mean of 4% of their body weight a day. The result indicated that the mean of particular growth ratio at first treatment (0.54) has higher than second treatment (0.34) but in comparison with third treatment (0.46), there was no statistically significant difference (P<0.05).Also, the conversion ratio at first treatment (5.28) and third treatment (6.09) was lower than second treatment (35.66) and third treatment (20.91) was lower than second treatment (24.24), (P<0.05). This study showed that monoculture in small scale is eassible by utilizing artificial diet, if the water quality is exposed to change. In this survey, the conversion ratio of the fish was relatively high whereas the growth rate was low.
