0.05). Also, all treatments include immune stimulant, showed significant difference in food conversion rate (FCR) compare to control group (P<0.05). The minimum amount of FCR and the maximum amount of protein coefficient were obtained in glucan treatment. The higher numbers of red and white blood cells and the higher amounts of hemoglobin and hematocrit were observed in glucan and the lower were observed in the control group. The higher and the lower rate of lysozyme enzyme activity were related to glucan (5.38± 0.18) and control treatments (3.19± 0.05) respectively. While the percentage of neutrophil and monocytes were higher in glucan treatment, the highest percentage of lymphocytes was observed in lactoferrin treatment (73.66± 0.57). So, compare to the other stimulants, glucan can be used as a growth and immunity stimulant in common carp.]]>

Hence according to the results obtainer of present study, it can be concluded that the glycine improved the resistance can increase survival of common carp under salinity stress.]]>

However, this multi enzyme at none of the experimental groups had any effect on hatchability and sperm motility (P> 0.05). It is suggested using this multi-enzyme in fish diets with high economic value and improve the growth and reproductive performance of fish.]]>

Overall, the results of the experiment revealed that grey mullet fed with JE10 and JE15 diets showed better growth performance, feed utilization, body composition and digestive enzymatic activities than the control group, and use of diet containing 10 g/kgJ.adhaerens could suggest for grey mullet.]]>
