The effect of native probiotic (mixtures of Lactococcus lactis and Lactococcus lactis ) on growth rate and some of the hematological and immune system parameters of juvenile Huso huso were investigated.. One hundred fifty six Huso huso individual with average weight of 2.92±0. 16gr ± SD were fed by company Biomar diet (protein: 47%, lipid: 16%, carbohydrate:3/2%) that add probiotic to level of...
To study the effect of Ca/P ratio on P and Ca absorption excretion in hybrid sturgeon (Huso dauricus♀ X Acipenser schrenckii♂), five groups fish were intubated with 100 mg P·kg−1 BW ratios 0:1, 0.25:1, 0.5:1, 1:1, 2:1. Plasma concentrations significantly elevated at below 2:1, highest value was obtained 0.5:1. content increased ratio. Urine rate 0.5:1 higher than that 0:1 The urea rates observe...
In the present study, different oxygen levels were examined in two weight groups of great sturgeon Huso huso including small size (with initial weight 280.9 ± 49.2 g) and large size (with initial weight 1217.9 ± 138.1 g). The fish were kept in hypoxia (2-3 mg/l), normoxia (5-6 mg/l) and hyperoxia (9-10 mg/l) conditions for 8 weeks and then were individually placed in the tanks with oxygen lev...

In order to have a sustainable management on Persian sturgeon as a highly commercial species in the South Caspian Sea, we need to identify its population structure and the level as well as its conservation status in their natural habitat. To develop a conservation program for this all Caspian Sea' sturgeon species it requires knowledge of its genetic diversity using reliable molecular...
Fish oil in the diet of fish is constantly at the risk of oxidation. In this study, the effects of feeding sturgeon hybrid (Huso huso ♂ ×Acipenser ruthenus ♀) with different levels of oxidized fish oil (OFO) on thyroid hormones were investigated. Three experimental diets were made by replacing 0 (control), 50 and 100% OFO were made. Ninety hybrid sturgeon, with the initial weights of 212....
