An overview on Snow trout (Schizothorax zarudnyi) biology
The Snow trout, Schizothorax zarudnyi Nikolskii, 1897 belongs to Cyprinidae family, endemic to Hamoun Lake, Sistan, Iran. Female fish mature at 4 years old, a few at 3 years old, and male fish at 3 years old, and live in the rivers and lagoons of Hamoon (stagnant waters) and spawn in the same place. Natural fish populations have declined during the last several years because of environmental de...
متن کاملMorphological Study of the Digestive Organs (Oesophagus, Intestinal Bulb, Intestine, Rectum) in Post Flexion to Finger Ling Stages of the Himalayan Snowtrout Schizothorax Plagiostomus (Heckel)
The morphology and relative length of gut (RLG) of the digestive tube among the larvae of S. plagiostomus is directly related to the age and size of the larvae. The digestive tube is almost straight when larvae are less than 1.5 cm in length, but as the size of larvae increases the gut increases in length and The RLG value also increase as 1.5 cm long larvae are having RLG value 1.0. While in 6...
متن کاملYOLK SAC TUMOR OF VAGINA
Malignant germ-cell tumors (MGCT) are rare tumors of childhood accounting for less than 3% of pediatric malignancies. Endodermal sinus tumor (EST) forms the most common histologic subtype of MGCT. The vagina is an extremely rare site for GCTs. An 8-month-old female was admitted with a short history of vaginal bleeding, and a mass protruding from the vagina.

متن کاملthe effect of traffic density on the accident externality from driving the case study of tehran
در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولEffects of different light intensities and photoperiods on growth, survival rate and yolk-sac volume changes of the Persian sturgeon (Acipenser persius) larvae
The aim of this study was to assess the effect of different light intensities and photoperiods on growth, survival, and the yolk sac absorb of the Persian sturgeon, Acipenser persicus, larvae. Larvae were reared from hatching to yolk sac absorb (eight days) at four light intensities (0, 50, 150 and 300 lux) and three photoperiods (00L:24D, 12L:12D and 24L:00D) which consisted of seven treatment...
