background: faba bean (vicia faba) is a rich source of protein and carbohydrates that is used as a vegetable ingredient in diet of livestock, poultry and fish, in many countries. objectives: this study was conducted to assess the effects of different levels of faba bean on the serum lipid levels and liver function of farmed beluga sturgeon (huso huso). methods: 144 juvenile beluga (82.38 ± 0.83...

This study was designed to determine the influence of thermal level and duration chilling period on initiation progress gonadogenesis gametogenesis under controlled conditions in pikeperch (Sander lucioperca). A set 120 fish distributed into eight tanks (15 per tank). The effects two temperatures (6 or 12°C) combination with durations period, either short (S; 75 days at 6°C 125 long (L; 135 185...

For the first time, pre-hibernation sizes of “storage” organs (liver and fat bodies), type, concentration total content reserve substances (glycogen or lipids) in these muscle tissue, their change during freezing freeze tolerant specimens moor frog (Rana arvalis) Siberian population were studied. In autumn, relative weight liver (hepatosomatic index) studied individuals reaches 10%, which is 2–...

AIM To evaluate the effects of melatonin (Mel) on oxidative stress in an experimental model of bile duct ligation (BDL). METHODS Male Wistar rats (n = 32, weight ± 300 g) were allocated across four groups: CO (sham BDL), BDL (BDL surgery), CO + Mel (sham BDL and Mel administration) and BDL + Mel (BDL surgery and Mel administration). Mel was administered intraperitoneally for 2 wk, starting on...

It is generally believed that Bacillus thuringiensis var. israelensis (Bti) biopesticides are harmless to non-target organisms; however, new research shows controversial results. We exposed acutely and chronicallyLithobates sylvaticusandAnaxyrus americanus tadpoles until metamorphic climax VectoBac 200G (granules) 1200L (aqueous suspension) at 300–20,000 ITU/L covering field-relevant concentrat...

A study was conducted to determine the effects of dietary vitamin C on growth performance, feed utilization and carcass biochemical composition of Barbus sharpeyi fingerling. Five diets containing (0, 500, 1000, 1500 and 2000 mg kg-1) of ascorbic acid were fed to benni fingerlings (6.96±0.3 g) in triplicate tanks and twice daily for a period of 56 days. The weight gain significantly increase...

The main objective for the present research was to assess the effect of cyclic starvation and L- carnitine supplementation on growth (body final weight, hepatosomatic index (HSI), daily growth rate (DGI), feed conversion ratio (FCR) and voluntary feed intake (VFI)), body composition (crude protein, crude lipid, ash and moisture), biochemical (plasma total protein, glucose, cholesterol, triglyce...

In this study, Effects of garlic (Allium sativum) extract on growth indices and hemolymph parameters of Litopenaeus vannamei with mean weight 18.21±0.29 g were studied for a period of 56 days. This study was conducted inside 300-liter polyethylene containers as four treatments each with four replicates and each replicate testing 5 shrimps. A basic diet supplemented by 0 (control), 40, 80 and 10...

 Concentration of heavy and toxic metals Cu, Zn, Cd, Pb and Hg were determined in liver and muscles of Rutilus frisii kutum and their relationships with growth parameters (length, age, condition factor) and hepatosomatic index were examined. Thirty-six fish samples were collected from February through March 2009 caught by beach seine in the southwest parts of the Caspian Sea. Atomic ab...
