A 3×4 factorial experiment was conducted for 45 days to determine the effects of diets containing different levels of protein and fat on growth of fingerlings Beluga (Huso huso L.1758). Twelve different diets were formulated with 3 levels of protein (45,50 and 55) and 4 levels of oil including fish oil and sunflower oil (0.5 ,4 , 8 and 12). 1260 Beluga fingerlings with an initial body weight (I...

in order to evaluate the effects of drought stress at different phenological stages on growth indices of chickpea (cicer arietinum l.) cultivar jam, an experiment was carried out at the research greenhouse of faculty of agriculture, ferdowsi university of mashhad, using a completely randomized design with four replications. drought stress was applied by preventing irrigation until the soil mois...
a study of the biokinetics of anaerobic digestion of municipal solid waste (msw) was carried out using anaerobic batch digester. from the experimental results, the kinetic parameters (coefficient values) of the digestion of the msw were determined. the maximum rate of substrate utilization (k), saturation constant (ks), endogenous decay coefficient (kd), biomass yield or microbial growth yield ...
background: the protein hormone granulocyte colony-stimulating factor (gcsf) stimulates the production of white blood cells and plays an important role in medical treatment of cancer patients. methods: an efficient process was developed for heterologous expression of human gcsf in e. coli bl21 (de3). the feeding rate was adjusted to achieve the maximum attainable specific growth rate under crit...
The purpose of this study was to evaluate the effects of livergol drug on growth indices and prevention of fatty liver disease in different levels of fat in common carp diets. In 2017, 9 diets of different nutrients were prepared with 3 levels of 0, 0.5 and 1% livergol and three levels of 5, 10 and 20% fat. The fish were fed for 180 days. After the end of breeding period, fish growth indices (e...
This study was carried with aim to investigate the restriction of feed, compensatory growth and the effect of probiotic (Bacilact) on growth performance, food productivity, survival and carcass composition of rainbow trout. Experiment was performed using a completely randomized design with three treatments consist of without hungry and basilicate treatment, feed restriction treatments with and ...
Nowadays, the entrance of nanoparticles into high seas has led to toxic effects on aquatic organisms. Copper oxide nanoparticles is among the most widely used nanoparticles. The presence of these nanoparticles in the aquatic environments cause new environmental problems, which indicate the necessity of the examination of the effects of these nanoparticles on the aquatic organisms. The alfalfa p...
This study was conducted to evaluate the influence of exogenous supplement Natuzime plus enzyme on growth performance, body composition and survival rate of beluga (Huso huso) juveniles. Juveniles (n = 17 fish per each tank with initial weight of 30 g) were randomly distributed in 150-L tanks and fed with four diets (each in three replicates) containing 0, 2, 5 and 10 % of Natuzime plus multi ...
