Abstract

the present study aimed to compare immune parameres of skin mucus and plasma in Persian sturgeon and Russian sturgeon. The mucus and plasma samples was collected from 20 specimens (10 Persian and 10 Russian sturgeon). Total protein, lysozyme, alkaline phosphatase (ALP) and total immunoglobulins of the samples were measured. The levels of Total protein, immunoglobulin, alkaline phosphatase of Persian sturgeon in plasma and mucus were, 8.46 ± 0.26, 7.6 ± 1.111, 38± 1.6, 23± 1.4, 134.06 ± 8.77 and 23± 1.4, respectively. The levels of Total protein, immunoglobulin, alkaline phosphatase of Russian sturgeon in plasma and mucus were, 9.71 ± 0.75, 8.2 ± 1.40, 36.6 ± 1.4, 19.8 ± 2.4, 83.70 ± 19.68 and 23.17 ± 2.54, respectively. Results showed that the levels of Total proteinand total immunoglobulinin both samples of mucus and plasma and levels of alkaline phosphatase in mucus were not significantly differ between the two species(P> 0.05), While the levels of lysozyme in mucus and plasma and alkaline phosphatase levels in plasma samples were recorded significant differences Between two species (P <0.05). Also no antibacterial activity in mucus and plasma of two species were recorded
