چکیده مقاله:

the aim of this study was to evaluate the effects of different Yucca schidigera extract levels on the Cyprinus carpio growth, body composition and culture water quality for 60 days. Experimental treatments were designed which include: T1 (control without extracts), T2, T3 and T4 treatments (containing 0.5, 1 and 1.5% Yucca extract respectively). In a completely randomized design, 360 Common carp fish with weight of 2.40 ± 0.04 g were reared in twelve 40-L plastic tanks. There was significantly higher final body weights in T4 (P< 0.05) compared with control (T1) and other experimental treatments. Similarly, significantly better (P< 0.05) feed conversion ratio (FCR), 2.01± 0.37 and protein efficiency ratio (PER), 0.17 ± 0.01 was noticed in T4 compared to control. Approximate carcass analysis showed that the low levels of crude protein and the high levels of crude lipids in T4 treatment were 62.87± 2.63 and 26.29± 1.55, respectively. The experiment treatments had the lowest amount of ammonia and the highest amount of nitrate compared to the control treatment. The results of this experiment showed that the use of Yucca extract can improve the growth and the water quality of the common carp culture system.
