Abstract:
One of the important goals in the aquaculture industry is to increase fish production with the least stress from ammonia secretion. Yucca plant (Yucca schidigera) was composed of steroidal saponins, polysaccharides, and polyphenols, which have increase the intestinal flora activity to improving the digestive process, also great absorption capacity for harmful volatile compounds, such as ammonia and hydrogen sulfide. Therefore, the aim of this study was to evaluate the effects of different Yucca schidigera extract levels on the Cyprinus carpio growth, feed performance, 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 and length of 5.47±0.05 cm were reared in twelve 40-L plastic tanks. Different levels of extract were sprayed on commercial food and consumed at 4 times daily. There was significantly higher final body weights in T4 (p
