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...

[ 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...
