In recent years, white, ellipsoid, round or elongated nodules were found in body cavity of this fish species which in preliminary microscopic examination were recognized as microsporidia. To determine the approximate prevalence rate of microsporidian infection and to establish its taxonomic position, 50 lizardfish were boug...
[ 2 ] - Histopathological study of gills in experimentally amoebic gill disease (AGD) infected Atlantic salmon, Salmo salar, L.
Amoebic gill disease (AGD) is the most important parasitic disease of Atlantic salmon industry inAustralia. Atlantic salmon (Salmo salar) experimentally infected with Neoparamoeba sp. apparently showedAGD gross signs on the gill and an amoebic-associated gill pathology. Physico-chemical factors of waterduring the experiment were monitored regularly and were approximately constant (temperature: ...
[ 3 ] - Study on effect of salinity level of water on electrocardiogram and some of blood serum minerals in grass carp, Ctenopharyngodon idella
In this study the effects of salinity on the electrocardiogram and some of blood serum minerals in grass carp were investigated. For this purpose, grass carp were exposed to concentrations of 4, 8 and 12 g L-1 salinities and electrocardiogram of all fish was recorded. Blood samples were also collected from all fish and serum minerals were measured. Our results indicated that mineral ...

Objective- This study aims to determine the efficacy of propofol in grass carp anesthesia and to examine the impact of the drug on electrocardiogram, pH and blood gases in this fish species. Design- Experimental study. Animals- 120 apparently healthy grass carps, weighting between 1-2 kg. Procedure- Fishes were sorted randomly into 12 groups of 10 fish each. Five groups were anesthetized by bat...
[ 5 ] - جدا سازی و شناسایی مولکولی ویبریو هاروی از ماهی باس دریایی آسیایی پرورشی در مزارع استانهای جنوبی کشور ایران
ویبریو هاروی (.Vibrio harveyi) یکی از عوامل اصلی ایجاد بیماری ویبریوزیس ماهی باس دریایی آسیایی در بسیاری از مزارع پرورش ماهیان دریایی در قفس در دنیا محسوب میشود. هدف از تحقیق حاضر، جداسازی و شناسایی این باکتری از ماهی باس دریایی پرورشی در مزارع استانهای جنوبی کشور (خوزستان، بوشهر و هرمزگان) بود. درمجموع تعداد 110 قطعه ماهی (80 قطعه ماهی بیمار و تعداد 30 قطعه ماهی به‌ظاهر سالم) در دامنه وزنی 7...
[ 6 ] - Achlya infection in an Oscar (Astronotus ocellatus) with typical symptoms of saprolegniosis

An Oscar fish was referred to the Veterinary Hospital, Shahid Chamran University of Ahvaz, Ahvaz, Iran with saprolegniosis symptoms including los...
[ 7 ] - بررسی نقش باکتری ویبریو هاروی در تلفات ماهیان باس دریایی آسیایی (Lates calcarifer) در مزارع استان های جنوبی کشور به روش کشت و واکنش زنجیره ای پلی مراز
ویبریو هاروی به عنوان بخشی از فلور رودهی ماهیان دریایی گوشتخوار، یکی از عوامل اصلی ایجاد بیماری ویبریوز ماهی باس دریایی آسیایی در بسیاری از مزارع پرورش در قفس در دنیا محسوب میشود. هدف از این مطالعه، بررسی نقش این باکتری در تلفات ماهی باس دریایی آسیایی در مناطق جنوبی کشور بود. در این مطالعه در بررسی 11 مورد تلفات ماهی باس دریایی آسیایی پرورشی، تعداد 110 قطعه ماهی (80 قطعه ماهی ب...
