این پژوهش به منظور ارزیابی تأثیر سطوح مختلف پربیوتیک مانان الیگوساکارید بر شاخص های رشد، بازماندگی، ترکیب لاشه و تراکم لاکتوباسیل روده در فیل ماهی (huso huso) جوان پرورشی به مدت 46 روز انجام گرفت. آزمایش با استفاده از طرح کاملاٌ تصادفی شامل سطوح صفر (شاهد)، 2 و 4 گرم پربیوتیک مانانالیگوساکارید به ازای هر کیلوگرم جیره در قالب سه تیمار با سه تکرار طراحی شد. آزمایش درون مخازن فایبرگلاس 2000 لیتری...
این پژوهش به منظور ارزیابی فاکتورهای خونی فیل ماهیان 3 تا 4 ساله پرورشی در پن در مرکز صید و فراوری آشوراده (چالاشت) واقع در حوضه جنوبی دریای خزر، در فصول مختلف سال طراحی و انجام شد. به این منظور، نمونه برداری از خون 10 قطعه فیل ماهی پرورشی در هر فصل از هر یک از پنهای تحت مطالعه (سه عدد پن) با وزن متوسط (g 32/757 ± 01/2698) و میانگین طول کل ( cm53/5 ± 98/77) انجام و میزان آنزیم آسپارتات آمینوتر...
از آنجا که بیشتر تلاش ها برای تعیین جنسیت ماهیان خاویاری به ماهی های با سن بیشتر از سه سال معطوف بوده است، چنین به نظر می رسد که تعیین جنسیت این ماهی ها در سنین کمتر از سه سالگی به سادگی میسر نمی باشد. در این تحقیق به منظور بررسی امکان تعیین جنسیت فیل ماهی کوچکتر از سه سال، گناد 12 قطعه فیل ماهی یک ساله و 12 قطعه فیل ماهی دوساله (در مجموع 24 قطعه) پرورش یافته در استان قم مورد مطالعه قرار گرفتن...
The effects of n-3 highly unsaturated fatty acids (n-3 HUFA) were studied on Beluga (Huso huso) fish larvae by feeding fish larvae with live food enriched with 4 different oils (ICES 30/4, tuna eye oil, flaxseed oil and linseed oil) containing different levels of n-3 HUFA including 27.19, 20.33, 12.71 and 0.39 mg g-1 dry weight of oil, respectively. Fish larvae weighing 30.00±2.00 mg were rand...

Hematological and biochemical changes were studied in beluga (Huso huso) weighing 450±50g in the presence of b,1-3, D-glucan as a single intraperitoneal injection (0.3mg/kg body weight) once, and thereafter a chronic exposure to organophosphate, diazinon at concentration of 1.5 mg/L as a continuous bath for 63 days at 22±1ºC. Results of erythrocyte profile in fish treated with glucan, but with...
early body shape changes of beluga sturgeon were studied using landmark-based geometric morphometric approach to recognize its allometric growth pattern. sampling was done from hatching up to 50 days post hatching (dph). left side of specimens were photographed using digital camera and nine landmark points were digitized on two-dimensional images. total length (ti) was measured using the softwa...
the aim of the present study was determination of reference values of blood serum enzymes of huso huso. descriptive study. 18 male and 18 female huso huso was studied. blood samples were obtained from caudal vein of 18 males and 18 females and the levels of enzymes were measured by an autoanalyzer. parametric t- test and pearson correlation test. results of measurements for total samples are as...
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...
Zearalenone (ZEA) as mycoestrogen is found in human foods and animal feeds. Its estrogenic potency depends on its biotransformation fate. The hepatic biotransformation of ZEA in two species of sturgeon fish (Acipenser persicus and Huso huso) was investigated. ZEA was incubated with the hepatic microsomal and post-mitochondrial sub-fractions in the presence of NADPH and the metabolites were dete...
