ماهیان خاویاری جزء ماهیان با ارزش اقتصادی دریای خزر هستند، اما مطالعات محدودی در خصوص نیازهای اکسیژنی آنها در دسترس است. در مطالعه حاضر اثر سطوح مختلف اکسیژن بر شاخصهای خونی دو گـروه وزنی از فیل ماهی huso huso شامل ماهیان اندازه کوچک (با وزن اولیه ۲۸۰/۹ ±۴۹/۲ گرم ) و اندازه بزرگ )با وزن اولیه (۱۳۸/۱ ±۱۲۱۷/۹گرم) ) (se ± میانگین) بررسی شد. تیمارهای اکسیژن شامل هیپوکسی، (۲-۳ mg/l نورموکسی ) (۵-۶ ...
In this study, the effects of replacing fish meal with soybean meal on growth performance, feed efficiency, body composition, fatty acid profile and gut lactic acid bacteria of beluga sturgeon, Huso huso. Nine diets were formulated (40% crude protein) in which soybean meal was replaced by fish meal at 0 (control), 40 and 80% supplemented and with three multi-enzyme level 0, 1 or 2 g/kg of Kemin...

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...
This study was accomplished to investigate the effect of Artemia urmiana nauplii enriched with Pediococcus acidilactici as probiotic on growth performance and survival rate of great sturgeon, Huso huso. Artemia nauplii were enriched with P. acidilactici at a final concentration of 1010 CFU mL-1 in three time dependent treatments as 3 h (T3), 6 h (T6), 9 h (T9), and one non-enriched Artemia as ...
This experiment wascarried out to explore the effect of use of combinations of permeating cryoprotectant and non permeating cryoprotectant on thequality of frozen-thawed Beluga (Huso huso) spermas compared to the use of permeating cryoprotectant as a control. For this work methanol (MeOH) and dimethyl sulfoxide (DMSO)are used aspermeatingcryoprotectantsand bovine serum albuminas a non permeatin...
