در این تحقیق اثر گرسنگی روی عملکرد رشد، انسولین و متابولیت های سرم خون جهت بررسی مکانیسم رشد جبرانی در بچه تاس ماهی ایرانی (acipenser persicus) با وزن متوسط 0/28± 108/06 گرم به مدت 8 هفته مورد بررسی قرار گرفت. این مطالعه در قالب یک طرح کاملاً تصادفی با پنج گروه آزمایشی، در سه تکرار شامل گروه کنترل (بدون دوره محرومیت غذایی) و تیمارهای یک (1w)، دو (2w)، سه (3w) و چهار هفته (4w) گرسنگی و چهار هفته ...
the effect of starvation and re-feeding was investigated on growth, hematology and biochemical parameters in juvenile persian sturgeon (acipenser persicus). three hundred and seventyfive fish (108±0.63 g) were divided into five feeding groups. the control group (c) was fed to satiation three times a day during the experiment. the four groups were starved for 1 (w1), 2 (w2), 3 (w3), and 4 (w4) w...
length-weight relationships and fecundity of 93 individual female acipenser persicus broodstocks were investigated. the specimens were caught during 2001-2005 from golestan, mazandaran and guilan provinces along the southern coast of the caspian sea. total length and weight of each fish was measured to the nearest 1cm and 100 g, respectively. age determination was carried out by using transects...
The sturgeon stock assessment was performed to aim at estimation of absolute and relative abundance and determination of species composition at lower 10 m depths using the Si-Sara2 RV vessel in the Iranian coasts of the Caspian Sea in Guilan, Mazandaran and Golestan provinces during 6-30 September 2011-2012. In this study, 40 stations were selected on the basis of stratified random sampling des...
Platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of Cerastes persicus fieldi and Echis carinatus were investigated. The partial fractionation was performed on a Sephadex G-100 column. Two fractions separated from Cerastes persicus fieldi showed anti platelet aggregation activity on ADP (200 µM)-induced platelet aggregation (ca 80% inhibi...
