| Abstract | ||
| The objective of this study was to investigate the efficacy of Roquette oil (Eruca sativa) which used as an additive in the diet of Common carp (Cyprinus carpio L.) young’s. Roquette oil added at different rates (0, 2, 4 and 6%) to the standard fish diet. Fish distributed at a rate of six fish per replicate in the aquaria with two replicate per treatment. Fish fed at a rate of 5% of body weight per day for a period of 40 days from 10.20.2010. Fish weight was measured in successive periods in addition to the measurement the physical and chemical proprieties. It was found that the addition of Roquette oil at rate of 6% gave the highest weight gain (2.83 gm) compared to the other diets, while the Relative and Specific Growth Rate was higher in all treatment compared to diet with 4%.When expected body weight was calculated using TGC values it was found that diets containing 2 and 6% Roquette oil fish weight was higher than other two diets after 180 days .Physical tests of diets showed that diets containing 2 and 6% Roquette oil revealed approximate and more efficient values than other two diets . It was concluded from the present study that the addition of 2% Roquette oil with plant oil or 6% totally replacement with plant oil lead to improve fish growth parameters and physical proprieties of diets. | ||
