Comparison on natural range of some hematological and biochemical indices of cultured Huso huso (Linnaeus, 1758) and Acipenser persicus Borodin, 1897 at different ages

The present study aims at investigating hematological and biochemical parameters (electrolyte and non-electrolyte factors) in two species of Acipenseridae, A. persicus and H. huso among three different ages, fry (2-7 months), juvenile (1-2 years) and brood stocks (7years). The study was conducted in Caspian Sea Sturgeon International Research Institute in 2012 during six month (spring and summer). For this purpose, 30 A. persicus and 30 H. huso were used (10 fry fishes, 10 juvenile fishes, 5 female and 5 male brood stocks in each group). Comparison of means of hematological and biochemical parameters revealed a significant difference among the three groups regarding potassium ion in H. huso and MCH and monocytes in A. persicus in all the indices except for RBC, MCHC and glucose.
