A field isolate of pike fry rhabdovirus (PFR-80560) isolated from roach was tested for pathogenicity in fry of roach Rutilus rutilus L., common carp Cyprinus carpio L., grass carp Ctenopharyngodon idella Valenciennes and rainbow trout Oncorhynchus mykiss Richardson. The fish were experimentally exposed to the virus by immersion in a virus-seeded water-bath. We also compared the pathogenicity of...
Behavioral responses of silver carp (Hypopthalmichthys molitrix), bighead carp (H. nobilis), and common carp (Cyprinus carpio) to a complex, broadband sound were tested in the absence of visual cues to determine whether these species are negatively phonotaxic and the roles that sound pressure and particle motion might play mediating this response. In a dark featureless square enclosure, groups ...
Although both common and crucian carp survived 2 h of anoxia at 18 degrees C, the response of their brains to anoxia was quite different and indicative of the fact that the crucian carp is anoxia tolerant while the common carp is not. Using in vivo T(2) and diffusion-weighted magnetic resonance imaging (MRI), we studied anoxia induced changes in brain volume, free water content (T(2)), and wate...
the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
In the present study, the antioxidant activity of different concentrations of protein hydrolysate from Common carp (Cyprinus carpio) head at different hydrolysis time was investigated. For this purpose, 8 Common carp fish with average weight of 0.766±0.034 kg were prepared from market. Fish heads were hydrolyzed by Alcalase (1% v/w at 55˚C and pH 8) at different hydrolysis times (30, 60, 120 an...
Background: Herbicides are usually used to control weeds and some of them like glyphosate are nonsele ctive herbicides. Aquatic environments are usually the last destinations of agricultural pesticides, which disrupt the metabolic processes of organisms. Thus, the aim of this study was to evaluate acute toxicity of glyphosate on the survival rate of common carp, Cyprinus carpio. Methods: A to...
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...
Highly unsaturated fatty acids (HUFAs) are crucial for the nutritional health, physiology, and reproduction of vertebrates. The Δ6-desaturase and Elovl5 elongase genes produce essential enzymes in the biosynthetic pathway of HUFAs. Single nucleotide polymorphism (SNP) analysis of genes functionally related to the growth traits of the common carp (Cyprinus carpio var. Jian) can provide useful in...
A group of 107 F1 hybrid common carp was used to construct a linkage map using JoinMap 4.0. A total of 4877 microsatellite and single nucleotide polymorphism (SNP) markers isolated from a genomic library (978 microsatellite and 3899 SNP markers) were assigned to construct the genetic map, which comprised 50 linkage groups. The total length of the linkage map for the common carp was 4775.90 cM w...
