Abstract :
The intensive culture of common carp (Cyprinus carpio) was surveyed in fiberglass tanks (2×2 m) feeding pellet during 8 weeks. 201 fish of common carp were 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 was no statistically significant difference between fish weight in relation to replicate treatment. 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) was higher than second treatment (0.34) but in comparison with the third treatment (0.46), there was no statistically significant difference (P<0.05). Also, the conversion ratio at the first treatment (5.28) and third treatment (6.09) was lower than the second treatment (35.66) and the third treatment (20.91) was lower than second treatment (24.24). The survey showed the possibility of maintenance of monoculture common carp in small scale by utilizing artificial diet, if the water quality is exposed to change. In this survey, the conversion ratio was relatively high but the growth ratio was low.
