Abstract
The present study was to evaluate the effect of dietary yeast cell wall (Saccharomyces cerevisiae) and cinnamon essential oil (Cinnamomum verum) supplementation on growth indices, serum biochemical parameters and immunity of rainbow trout (Oncorhynchus mykiss) fingerlings. Using a 2×2 factorial experiment, 276 fingerlings (9.67 ± 1.20 g) were fed four different experimental diets (including control diet, diet supplemented with 1.5 % yeast cell wall or 1 % cinnamon essential oil and a diet containing 1.5 % yeast cell wall and 1 % cinnamon essential oil) for a 60-day period. At the end of the trial, specific growth rate and weight gain significantly decreased in fish fed diet supplemented with 1% cinnamon essential oil (P≤0.05), however, feed conversion ratio was not statistically differed amongst treatments (P>0.05). Fish fed diets containing 1% cinnamon essential oil had the highest hepatosomatic index (P≤0.05). The highest red blood cell count and blood hemoglobin content belonged to group fed diet containing 1% cinnamon essential oil (P≤0.05). Simultaneous feeding with yeast cell wall and cinnamon essential oil significantly resulted in higher hematocrit value. Serum alkaline phosphatase activity was significantly increased in group fed diet containing 1.5% yeast cell wall. Dietary cinnamon essential oil supplementation also resulted in lower alkaline phosphatase, aspartate aminotransferase and gamma glutamyltransferase activity of serum (P≤0.05). The highest serum total protein and globulin content and lysozyme activity were observed in fish fed diet only supplemented with yeast cell wall (P≤0.05). In conclusion, dietary cinnamon essential oil and yeast cell wall inclusion resulted in improved immunity of rainbow trout fingerlings.

Abstract
In this study, the effects of different levels of dietary supplementation with vitamin C, astaxanthin and lecithin on ionic (K+, Na+, Ca2+ and Mg2+) and biochemical (Total protein, cholesterol and glucose) indices of ovarian fluid, also its effect on sperm motility duration in Caspian brown trout (Salmo trutta caspius) were investigated. For this purpose, nine experimental diets: C0A0L0 (0 mg kg-1 vitamin C, 0 mg kg-1 astaxanthin and 0% soybean lecithin), C300A50L0, C700A100L0, C0A50L6, C300A100L6, C700A0L6, C0A100L9, C300A0L9 and C700A50L9 were formulated and broodstocks (2.51±0.05 kg) were fed for four months. After maturation and stripping, ovarian fluid was separated for ionic and biochemical indices. To evaluate sperm motility, 1 μl of milt was placed under a microscope with fresh water (as a control treatment) or ovarian fluid of experimental fishes. Sperm motility was measured with a chronometer. Results showed that the highest amounts of Na+, K+, Ca2+ and Mg2+ ions were obtained in ovarian fluid of C300A100L6, C300A100L6, C0A100L9 and C300A100L6, respectively, which were significantly different from C700A50L9 (p<0.05). Also, the highest levels of protein, cholesterol and glucose were observed in C700A50L9, C0A50L6 and C0A100L9 treatments, which were significantly different from C0A0L0 treatment (p<0.05). Lowest duration of sperm motility was obtained in fresh water (43.96±2.25 seconds) which was significantly different from other treatments (p<0.05); however, the highest sperm motility was observed in C300A100L6 and C0A100L9 treatments (80.76±2.03 and 80.7±1.76 seconds, respectively).
