Effect of different levels of Salicornia sp. plant extracton growth performance and body chemical compositions of grey mullet, Mugil cephalus Linnaeus 1758

This experiment was conducted to evaluate the effect of different levels ofSalicorniasp plant extracton growth performance and body chemical compositions of grey mullet, Mugilcephalusfor 60 days. The experiment was conducted in a completely randomized design with 240 of grey mullet (with average weight of 8.42±0.43g) in 4 treatments and 3 replicates (n=20 in each replicate) and included: control group without using plant extract,  another groups (treatment 2,3and 4) the amounts of this extract were 50,1000 and 1500mg/kg food. The results showed that at the end of experiment, the highest FW (26.74±2.03g), WG (216.78±14.97%), DGR (0.20±0.12%), SGR (1.91± 0.17), survival (93.60± 1.14%), the lowest FCR (1.44±0.11 %), the highest PER (9.03±1.39) were observed in the diet containing 1500mg /kg plant extract in all of these parameters and showed a significant difference compared with control treatment (P<0.05). The highest crude protein and moisture were observed in the diet containing 1500mg /kg plant extract. Finally, the present results suggest that diet containing 1500 mg/kgSalicorniasp extractcould improve growth performances and carcass quality in M. cephalus.
