The aim of the present study was to evaluate the effects of dietary Guava (Psidium guajava) leaves powder (GLP) on growth parameters, feed utilization as well as some serum parameters of common carp (Cyprinus carpio) fingerlings. Common carp fingerlings (18.88±0.27 g) were supplied and stocked in twelve fiberglass tanks at density of 14 fish per tank. Fish were fed experimental diets contains 0...

Seed pretreated with plant growth regulators can improve germination parameters, growth, and yield of crops. Thus, in two greenhouse and field experiments, effects of seed treatment with 0.1 mM salicylic acid (SA), 1µM methyl jasmonate (MJ), 1.5% humic acid (HA), and water (as Control) on germination parameters, seedling growth, and also growth and fruit yield were studied. In the first experim...

The aim of the present study was to evaluate the effects of different levels of prebiotic on growth performance and non-specific immune parameters of zebra fish. Four hundred and twenty fish (mean weight 45 ± 0.1 mg) were supplied, randomly stocked in aquaria assigned to four treatments repeated in triplicates and fed with experimental diets contain 0, 0.5, 1 and 2% prebiotic for 8 weeks. At th...

This investigation was carried out to determine the effect of feeding strategies on growth performance, biochemical parameters, and hematological indices in male rainbow trout (Oncorhynchus mykiss) broodstocks. For this purpose, 45 broodstocks with 475.55 ± 54.24 g (mean ± S.D) were divided into three treatments and fed at satiation, restricted feeding (50% of satiation limit), and starvation...

a simple, sensitive and selective method for solvent extraction and spectrophotemetric determination of lanthanum (ii) europium (iii), and cerium (iii) is described , the rare earth metals are extracted into chloroform solution of n-phenylbenzohydroxamic acid (pbha) at ph 9-10 various parameters are studied to optimize the extraction conditions. the molar absorptivity is found to increase from ...

asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
