Abstract
The effects of alcoholic extract from pomegranate (Punica granatum) peel on some hematological and biochemical parameters, including RBC, Hb, Hct, MCV, MCH, MCHC, WBC, TP, CHO, GLU, LDL, HDL, Glb, TG, GOT, GPT, Alb, ALK, LDH, and lysozyme activity of common carp )Cyprinus carpio( fingerlings (11.73 ± 1.81g) were studied for a period of 75 days. Treatments included different concentrations of ethanol extract of pomegranate peel (Zero: control, 50, 150, 300 and 600 mg/kg of diet). At the end of experiment, all fish were sedated for morphometric measurement and blood sampling. Significant increases in Hb, Hct and RBC in groups 300 and 600 mg/kg of diet were observed (P<0.05). Total protein in groups 150, 300 and 600 mg/kg of diet showed a significant difference with other groups (P<0.05). Lysozyme activity was significantly enhanced in all diet containing pomegranate peel extract compared to the control group (P<0.05). In brief, the present study revealed an overall improvement in hematological parameters and lysozyme activities and total protein when 300 mg pomegranate peel extract was used in the diet.

Abstract
Aims: The aim of this study was to investigate the effect of dietary lemon peel (Citrus limon) essential oil on growth, hematological parameters, some of serum biochemical parameters and liver enzymes in rainbow trout (Oncorhynchus mykiss) juveniles. Materials & Methods: For this purpose, 144 rainbow trouts with an average initial weight of 95.05 ± 0.41 g were randomly stocked in four treatments containing different levels of lemon peel essential oil ( 0 (control), 200, 400 and 600 mg lemon peel essential oil/kg diet) and fed for eight weeks. Findings: The results showed the highest growth factors in treatments of 400 and 600 mg lemon peel essential oil/kg diet (p<0.05). Inclusion of essential oil in diet increased hematological parameters as compared to the control except MCV, MCH, MCHC and increased serum biochemical parameters by contrast to the control except glucose, triglyseride and cortisol (p<0.05). liver enzymes of ALT and AST showed no significant differences among treatments containing essential oil and LDH exhibited no significant differences among 400, 600 mg essential oil/kg diet and the control treatment (p>0.05), but ALP amount significantly increased in essential oil treatments in a comparison to the control (p<0.05). Conclusion: Overall, these results indicated using 400 mg essential oil in rainbow trout diet could improve growth, hematological and some serum biochemical parameters of rainbow trout without any negative effects on liver.
