Abstract: (8617 Views)
This study was conducted to evaluate the effects of different levels of Mentha piperita extract on growth factors, survival rate and body composition of Rutilus frisii kutum fry. For this purpose, four groups of fish with mean weight of 1.12± 0.14 g were raised for 56 days in plastic tanks (40 fish to each tank) and feeding with different levels of M. piperita with concentrations of 0, 1, 2.0 and % 3.0. At the end of the trial, growth factors (final weight, weight gain, SGR, feed conversion ratio (FCR), survival rate and body composition were determined and compared with control group. Our results showed that R. frisii kutum fry fed on diet supplemented with 3% M. piperita had significantly higher growth factors and survival rate compared to other treatments (P<0.05). The study of body composition showed no significant difference between different treatments (P>0.05). Based on the results, using of M. piperita extract, especially at the level of 3.0% can improve the growth performance and survival rate of R. frisii kutum fry.
