Abstract
The aim of this study was to evaluate the effects of synbiotic Lactobacillus casei PTCC 1608 and immunogen prebiotic on immunological and hematological factors of Cyprinus carpio. 300 fish (with the average weight of 40 g) were fed for 75 days with various diets including the diets containing 0.5 (A), 1 (B) and 1.5% (C) immunogen and L.casei probiotic with the concentration of 5×107 CFU/g, treatment D contained only L.casei probiotic with the concentration of 5×107 CFU/g and the control treatment without synbiotic (E). Results showed that the levels of white blood cells in the treatment A, B and C on day 60 were significantly different as compared to day 0 and the control group (P<0.05). The levels of red blood cells in the treatment A, B, C and D on day 30 were at the highest level and were significantly different as compared to day 0 and the control group (P<0.05). The levels of lysozyme in the treatment C and D until day 30 and in other treatments until day 60 were significantly different from the control group (P<0.05). The administration of synbiotic in the treatment C and D on respiratory burst activities on day 30 and in other treatments until day 60 and the level of complement on day 60 in the treatment A were significantly different as compared to those on day 0 and the control group (P<0.05). The results suggested that dietary administration of synbiotic can improve some immunological and hematological parameters and the best level of immunogen was 1% with synbiotic

Abstract
The current study aimed to evaluate effects of four levels (0, 2, 4 and 6 % of diet) of soybean lecithin in the isoproteic and isoenergitic (50% protein and 18.5 kj/g) diets on growth performance, feed utilization and hematological parameters of juvenile sobaity seabream (Sparidentex hasta) with initial weight of 37.9±0.16 g. At the end of 56 days of feeding trial, results showed that growth performance increased with increasing dietary lecithin from 0 to 6%; however, growth decreased with increasing dietary lecithin from 6 to 9%. Fish fed the 6% lecithin diet had the highest final weight (86.19±2.99 g), weight gain (48.41±3.6 g) and specific growth rate (1.47±0.07) (p<0.05). Survival rate, feed conversion and protein efficiency ratios as well as hematological parameters were not changed in different groups (p>0.05). The results of this research showed that, inclusion of 6% of soybean lecithin in diet for sobaity seabream juvenile is optimum for improving growth performance parameters in this species.

Abstract
Recently use of Acidifier (group of organic acids) increased in aquaculture. The purpose of this study was to evaluate the effects of acidifier (sodium diformate and citric acide) on growth performance, nutrition indices, immune and hematological parameters of the juvenile Oncorhynchus mykiss. A total of 630 juvenile Oncorhynchus mykiss (16.55 ± 0.72) randomly divided into seven experimental treatments (Three replicates each). All groups fed with experimental diet for 60 days. Bioassay conducted in first day and after sixty days and then growth parameters were investigated. The experimental diets were contain 0.2, 0.4 and 0.6 % sodium diformate(NDF) and 0.2, 0.4 and 0.6 %, combination of NDF and citric acid with equal ratio. Diet control was without acidifier. Results showed that almost all growth and hematological parameters were increased in fed groups with 0.2 % supplemented food with NDF and citric acid compare to the control group. The best FCR showed in the groups fed with 0.2 % (P<0.05). Although haematological parameters of fish in groups fed by 0.2, 0.4 and 0.6 %, NDF and citric acid changed significantly after 60 days of feeding with experimental, no changed were observed in WBC value among the groups (P>0.05). The results show that the immunological parameters including, total serum protein, immunoglobulin and bactericidal activity serum were affected significantly at Acidifier (p<0.05) while Lysozyme activity serum and albumin was not affected (P>0.05). The results of this study indicated that 0.2 %, NDF and citric acid in the diet could be a useful food supplement and can be used to improve the growth parameters and immunity system in juvenile Oncorhynchus mykiss.

Abstract
The present study aimed to investigate the effect of the commercial probiotic BetaPlus® Ultra (BP Ultra) in combination with the galacto-oligosaccharide (GOS) or the isomalto-oligosaccharide (IMO) prebiotics in Caspian trout (Salmo caspius) parr. S. caspius (8.5±0.07 g) was randomly distributed in three dietary treatments including: control group, synbiotic treatment I (0.1% BP Ultra + 0.2% GOS) and synbiotic treatment II (0.1% BP Ultra + 0.2% IMO) and in nine 300 L circular polyethylene tanks with three replications per treatment and, then, fed for seven weeks. At the end of this experiment, growth performance and hepatosomatic index improved significantly in both synbiotic treatments compared to the control group (p<0.05). However, the trend of this improvement was more noticeable in the synbiotic treatment I compared to the synbiotic treatment II without any significant difference (p>0.05). The counts of red and white blood cells in the both synbiotic treatments were significantly decreased and increased compared to the control group, respectively (P<0.05). The values of hemoglobin, packed cell volume, and mean corpuscular hemoglobin in the synbiotic treatment I showed significant increases compared to the synbiotic treatment II (P<0.05). The highest significant levels of crude protein and lipid in carcass were observed in the synbiotic treatment II and the synbiotic treatment I, respectively (P<0.05). Dry matter of carcass was increased significantly in the synbiotic treatment I compared to the synbiotic treatment II (P<0.05). The lowest ash content of carcass was observed in the synbiotic treatment I with a significant difference compared to the synbiotic treatment II and the control group (P<0.05). The results of the present study demonstrated the remarkable efficiency of the synbiotic treatment II on the protein increase and lipid reduction in carcass, although the synbiotic treatment I had a better effect on growth performance and hematological parameters in S. caspius.
