The present study was performed to measure heavy metals (Pb, Zn, Cd and Cu) in the muscle, liver, gonad, intestine and digestive parasites of Pike (Esox lucius) in Anzali wetland. For this purpose, 90 fish Pike were sampled from Anzali wetland during 2020 and in the reproductive season (winter). During the experiment, total length, fork length, standard length and total weight were measured. Th...
In this research, growth rate, blood parameters and proximate composition of rainbow trout (Oncorhynchus mykiss) cultured in brackish and freshwater were evaluated. Two treatments (brackish and freshwater) in 3 replications were investigated. Six 1.5 m³ fiberglass tanks were used for this experiment, containing 180 rainbow trout specimens with average weight of 47.2±0.1g. Feeding rate in trea...
this experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. one hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...
The purpose of this study was to evaluate the effect of Nano TiO2 and Nano CNT on some germination indices and growth parameters of some hulled barley cultivars. The experiment was conducted in a laboratory at Shahrekord University during 2014. The study was a factorial, adopting a completely randomized design with four replications. Treatments consisted of titanium dioxide nanoparticles and ca...
in this study, growth and survival of the caspian whitefish, rutilus frisii kutum, (mean weight 0.59±0.06g) have been estimated at different rearing salinities (0, 5 and 10‰) and temperatures (24 and 28˚c). maximum fish weight gain (493.65±14.07%) and specific growth rate (sgr) (2.74±0.15%), and minimum feed conversion ratio (fcr) (1.66±0.06) were obtained at salinity of 5‰ and temperature of 2...
length- weight relationship and growth pattern, condition factor and length at first maturity of yellowfin seabream were investigated in the persian gulf by monthly sampling of 30 fish from september 2011 to august 2012. maximum (31.45± 4.32) and minimum (17.80± 1.85) values of fork length and maximum (720.46 ± 292.58 gr) and minimum (134.01± 45.62) values of body weight were in january and sep...
The aim of this study was to investigate the effect of red pepper (Capsicum annuum) extract on growth, blood, biochemical and non-specific immune parameters of 360 rainbow trout (Oncorhynchus mykiss) juveniles with average weight of 9.38±0.01 g. The fish were fed with a commercial diet containing 0, 0.25, 0.5 and 1% of C. annuum extract in 12 tanks (300L) with three replicates (30 fish per tank...

in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
