Abstract
The effects of Pediiococcus acidilactici and Lactococcus lactis was evaluated on survival rate and some immunological parameters of L. vannamei during three months of cultivations. Treatments included control group, Pediococcus and Lactococcus treatments and probotic treatmentsfed at 1×109 cfu g-1. The results indicated that probiotics increased the survival rate (P<0.05). The best immune performance was shown in the probiotics treatments; phenoloxidase activity, proteins, and globulin hemolymph showed significant difference compared to the control treatment (P<0.05), whereas there were no significant influence on lysozyme activity (P≥0.05). In general, pediococcus treatment showed the best performance in enhancing the immune responses and survival rate.

Abstract
The objective of this study was to evaluate the effect of probiotic, Pediococcus acidilactici (CNCM-MA 18/5 M, Lallemand, France) in concentrations of T1: 1 × 109, T2: 2× 109 and T3: 3×109 cfu / kg of diet on changes some hematological parameters of bream fry (Abramis brama orientalis, Berg 1949) in comparison with diet control, C, (untreated) for 60 days. One hundred eighty Bream fry with randomly in initial weight of 2.69± 0.22 g divided in 12 fiberglass tanks (110 L) and offered feed at 3-5% body weight, daily. At the end of the trial blood parameters measured. The total number of red blood cells, hematocrit, hemoglobin and white blood cells levels showed a significant increase in treatment fed with 2× 109 cfu probiotic per kilogram of diet (P<0.05). Indifferential white blood cell(WBC) count, the number of neutrophils and monocytes, and lymphocytes increased significantly in treatments fed with probiotics. The highest increase in neutrophils and monocytes, and the highest decrease in lymphocytes observed in T3 (3× 109 cfu kg-1). According to the results, it concluded that adding probiotic Pediococcus acidilactici to the fry bream (Abramis brama orientalis, Berg 1949) diet, increase blood parameters related to red blood cells (RBC), diseases resistance and improve non specific immune response in bream.
