این تحقیق به منظور تعیین تأثیر سطوح مختلف فسفولیپیدها phospholipids (PL) در رژیم غذایی بر پارامترهای خون بچه ماهی خاویاری (فیل ماهی) انجام گردید. بچه ماهیان با رژیم غذایی فرموله شده در چهار سطح مختلف رژیم غذایی PL: (D1) 0، (D2) 2، D3)) 4 و (D4) 6% تغذیه شدند. در پایان دوره آزمایش (56 روز)، نتایج آزمایش نشان داد که تفاوت معنیداری در متوسط غلظت هموگلوبین گلبول قرمز (MCHC) مشاهده گردید(P ...
Lactic acid bacteria are characterized as gram-positive, usually non-motile, non-sporulating bacteria that produce lactic acid as a major or sole product of their fermentative metabolism. In this study, the presence of lactobacilli were investigated in the intestines of beluga ( Huso huso) and Persian sturgeon ( Acipenser persicus ), inhabiting Caspian sea. The obtained data showed that various...
To determine the best live food and to reevaluate the optimal weaning period for beluga fish (Huso huso) larvae, seven experimental diets: Daphina (DP), Chironomids (CH), Gammarid (G), Daphina + formulated diet (DPFD), Chironomids + formulated diet (CHFD), Gammarid + formulated diet (GFD ) and formulated diet (FD ) in triplicate groups were fed to 4662 sixteen-days-old larvae which were captu...
هدف از این تحقیق اثر یک افزودنی کاملا طبیعی به نام کیتوزان بر تغییرات شاخصهای ترکیب تقریبی (رطوبت، چربی و پروتئین) و pH در فیله فیل ماهی (Huso huso) طی نگهداری در فریزر بود. این تحقیق شامل ۲ تیمار بود : تیمار فاقد کیتوزان (تیمار شاهد) و تیمار حاوی ۱٪ کیتوزان محلول در اسید. هر دو تیمار به مدت ۴ ماه در فریزر ۱۸- درجه سانتیگراد نگهداری شدند. فیله ها در روز صفر (۱۰ ساعت بعد از نگهداری در فریزر)...
In this study Amplified Fragment Length Polymorphism (AFLP) was applied to species identification of bester hybrids. Hybrids identification was performed by comparison of electrophoresis profiles with parental species. The simultaneous occurrence of diagnostic bands fixed in the parental species, genetic distance and identification and cluster analyses (UPGMA) allow a correct identification. ...
This paper presents the results of study on age, growth, mortality rates and yield-per-recruit of Beluga (Huso huso) living in Caspian Sea. The mean length of successive years, mortality rates and yield-per-recruit studies indicated that at present the resource is under heavy fishing pressure. For the female Beluga growth was regarded as comprising of three stages, and the von Bertalanffy param...

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....
