The aim of the present study was to detect polymorphism in Insulin like growth factor-I (IGF-I) gene of beluga (Huso huso) fish using PCR-SSCP technique and also investigation of its association with growth traits (condition factor, body length and weight). A total of 150 specimens of beluga were randomly selected and DNA was isolated from caudal fin using modified salting out method. Then two ...

This study was carried out with the aim of detecting the dietary effects of isoflavone-genistein on hematological and immunological parameters in beluga, Huso huso in a 12-week feeding period. Five isonitrogenous (45% crude protein) and isoenergetic (19.5 MJ kg -1) diets were formulated to contain four graded levels of isoflavone-genistein, namely 0, 0.2, 0.4, 0.8 and 1.6 g kg-1 diet. Fish (ini...
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 marker t...
Sturgeons are ancient and endangered species whose populations have been greatly reduced over the past few centuries due to habitat destruction overfishing for production of expensive caviar. All sturgeon listed in CITES Appendix II limit their trade; therefore, accurate identification is crucial. In this study, we performed whole-genome resequencing five species, including Kaluga (H. dauricus)...

In this study, the effect of Ethylenediaminetetraacetic acid (EDTA) was evaluated on growth performance and body composition in beluga (Huso huso) juveniles. For this purpose, a total of 225 beluga juveniles with initial weight 38.47 ± 0.58 gr (Mean ± Standard Division) were fed with five treatments with three replications including 0 g/kg EDTA (Control, C), 5 g/kg EDTA (EDTA 5), 10 g/kg ED...
In the present study, the physical and chemical factors including optimum temperature and pH, the effect of inhibitors, metal ions, oxidizing agents, and surfactants were assayed on the chymotrypsin activity from beluga (Huso huso) intestine. According to the obtained results, the optimum temperature and pH of the chymotrypsin were recorded at 50°C and 8, respectively, and its activity was extr...
اثر غلظت اکسیژن آب بر شاخص های خونی و رشد دو گروه وزنی از فیل ماهیان پرورشی (وزن اولیه 2/49±9/280 و 1/138±9/1217) بررسی شد. تیمار های اکسیژن شامل hypoxia (mg/l 3-2)، normoxia(mg/l 6-5) و hyperoxia (mg/l 6-5) به وسیله تنظیم آب ورودی و تزریق اکسیژن خالص برای تیمار hyperoxia، تنظیم شد. ماهیان به مدت یک هفته با تانک های آزمایش سازگار شده سپس به صورت تصادفی در 9 تانک در هر گروه وزنی توزیع (برای گروه...
هدف از این مطالعه، بررسی اثر غلظت انفرادی و تحت کشنده مس و کادمیوم بر شاخصهای بیوشیمیایی پلاسمای خون و کبد بچه فیل ماهی (huso huso) بوده است. به این منظور، در خرداد سال 1387، تعداد 54 عدد بچه ماهی (4 ماهه با وزن متوسط 8/6±4/55 گرم) به ترتیب، در معرض غلظتهای تحت کشنده 20 و 300 میکروگرم بر لیتر مس و کادمیوم در سیستم آزمایشی نیمهثابت به مدت 14 روز قرار گرفته و اثر غلظتهای مذکور بر شاخصهای بیو...
