The aim of this research was to evaluate the effects of oral recombinant bovine somatotropin (RBS) 1% on growth performance of rainbow trout (Oncorhynchus mykiss). 600 rainbow trout weighing 46±1 grams were randomly allotted in two groups including: 1) the control group and 2) RBS treated group, each in three replicates. The fish were hand-fed with commercial pellets. The fish received 200g R...
[ 2 ] - Effects of different dietary levels of AFB1 on survival rate and growth factors of Beluga (Huso huso)
In the present study, the impacts of various concentrations of Aflatoxin B1 (AFB1) on Beluga, Huso huso, under controlled conditions were investigated. Belugas (120±10g) were fed on diets containing 0, 25, 50, 75, and 100 ppb AFB1/kg of diet for 3 months. Results showed various levels of AFB1 do not significantly affect the specific growth ratio (SGR) (P < 0.05) of fish in different treatments...
[ 3 ] - بررسی میزان شیوع استرپتوکوکوزیس در ماهیان قزل الای رنگین کمان درمزارع پرورشی شرق استان مازندران (حوضه رودخانه هراز )
استرپتوکوکوزیس یک بیماری عفونی باکتریایی است که دراکثر مراکز تکثیر و پرورش ماهیان سردابی ( قزل آلای رنگین کمان) کشور مشاهده شده است . این بیماری دارای این قابلیت است که به شکل همه گیر مزارع ماهیان سردآبی را در اقلیم های مختلف تهدید نماید و خسارتهای اقتصادی زیادی را به صنعت آبزی پروری وارد نماید. در بروز ، گسترش و همه گیر شدن این بیماری عواملی از جمله دمای آّب ، میزان نیتریت، نیترات، آمون...
[ 4 ] - تاثیر عوامل خطر محیطی در بروز استرپتوکوکوزیس در مزارع پرورش ماهی قزلآلای رنگین کمان (Onchorhynchus mykiss) رودخانه هراز به روش Logistic Regression
استرپتوکوکوزیس یک بیماری عفونی باکتریایی است که در اکثر مراکز تکثیر و پرورش ماهیان سردابی (قزلآلای رنگین کمان) کشور مشاهده شده است. در بروز و همه گیری این بیماری عواملی از جمله حرارت، نیتریت، نیترات، آمونیوم، کدورت آب، اکسی‍‍ژن محلول، دبی، شمارش کلی باکتریائی و.. در بروز بیماری نقش دارند. این مطالعه با هدف شناسایی عوامل خطر محیطی و ارزیابی میزان تاثیر گذاری آنان در بروز استرپتوکوکوزیس وارائه پ...
[ 5 ] - تغییرات بافتی ناشی از تغذیه با جیره‌های حاوی مقادیر مختلف آفلاتوکسین B1 در میگوی سفید هندی
هدف از این مطالعه بررسی تغییرات بافتی ناشی از تغذیه با جیره‌های حاوی مقادیر مختلف آفلاتوکسین B1 در میگوی سفید هندی میباشد. در این مطالعه میگوهای سفید هندی (Fenneropenaeus indicus) با وزن (گرم 76/1 ± 79/11) با جیره‌های غذایی حاوی مقادیر 0، 20، 50، 100، 200، 400، 800 و ppb 1600 آفلاتوکسین B1 (AFLB1) بمدت 8 هفته تغذیه شدند. تغییرات آسیبشناسی بافتی در هپاتوپانکراس، بافت عضله و روده میانی در پایان...
[ 6 ] - Feasibility study providing a software model to predict incidence of White Spot Syndrome Virus in shrimp ponds contributed with physical and chemical factors in Iran
The objective of this survey was to provide a software ecological model to predict the incidence of WSSV in Litopenaeus vannamei ponds of Gwater area located in southeastern of Iran. The coding and grouping of effective factors, which were involved in the occurrence of White Spot Syndrome Virus (WSSV) including temperature, salinity, oxygen, pH, ammonia, silica, pond preparation and management ...

[ 8 ] - Determination Growth Parameters in Different Popullation of Specific Pathogen Free (SPF)Rainbow TroutBrood Stocksnc(orhynchus mykiss)
This study aimed to compare growth indices and production of rainbow trout breeders (Oncorhynchus mykiss) without any specific pathogens in various populations at the Fishery Research Center of Coldwater-Tonekabon. The project's implementation included collecting Pre-breeders were done in selected rainbow trout breeding centers (based on the approval of the Iranian Fisheries Organization and th...
[ 9 ] - Ontogenic development of digestive accessory glands in larval and juvenile Vimba bream, Vimba vimba (Pallas, 1814)
The current study investigated histological development and histochemistry of digestive accessory glands of Vimba bream Vimba vimba from hatching through 60th day after hatching (DAH). The samples were randomly taken from day 1 (hatching) until the full absorption of the yolk sac at day 7 and the day after that, then with 2, 5, and 10 days intervals until 60 DAH. The development of the digestiv...
[ 10 ] - Comparison of Huwa-San TR-50 solution efficiency with malachite green and Formalin on fungal contamination control of rainbow trout (Oncorhynchus mykiss) eggs in incubation stage
