Study on some blood immunological indices of the wild juvenile Persian sturgeon, Acipenser persicus in the coasts of the Mazandran province

In this study, a total of 65 juvenile Acipenser persicus (with mean length of 45 ± 28.1cm and 1 - 2 year old were captured during seven times trawling from 2009 till 2012in the Mazandran Province. The results showed that the mean of red blood cells(RBC) and white blood cells (WBC) were 585000 ± 15.1 and 30300 ± 32 per mm3 ofblood, respectively. Also, mean percentage of lymphocyte, monocyte, neutrophileand eozynophile were 83.1 ± 12, 2.9 ± 2, 8.3 ± 6.6 and 5.6 ± 3.2 %, respectively.Mean concentration of Immunoglobin M (IgM) in blood serum was 25.6 ± 8.7 mg/dl.The results showed no significant difference between samples (P> 0/05). Based onresults, the younger specimens were more sensitive to environmental changes thanolder ones. Hence, their immune indices have been decreased along with theirgrowth. Therefore, each change in immunological and haemotological factors canlead to a secondary responses in fish.
