the inhibition of pathogens growth as well as the shelf-life extension of seafood as a perishable product using safe methods is one of the most important issues that have been attracted fisheries and food science researcher’s attention. the purpose of this study was to evaluate the inhibitory effect of bunium persicum essential oil (eo) on inoculated listeria monocytogenes growth in simulated b...

in order to identify the sex marker in mahisefied, rutilus frisii kutum, samples from 5 male and 5 female fish were collected from the south caspian sea. polymerase chain reaction random amplified polymorphic dna (pcr-rapd) was performed using 124 primer sets. all bands were numbered using 1 and 0 scores corresponding to the presence or absence of bands, respectively and data were analyzed usin...

the purpose of the present study was to determine the acute toxicity (lc 50 ) of hgcl 2 and cuso 4 in caspian roach ( rutilus caspicus ) and cuso 4 in caspian kutum ( rutilus kutum ). the caspian roach lc 50 values for hgcl 2 at 24, 48, 72, and 96-hrs of exposure, were 0.64, 0.61, 0.42, and 0.28 mg l -1 , respectively, and for cuso 4 were 11.55, 5.08, 2.49, and 1.47 mg l -1 , respectively. the ...

bacteriocins are proteinaceous antibacterial compounds that exhibit bactericidal activity against species closely related to the producer strain. the aim of this research was to investigate the production of bacteriocin by bacillus spp. isolated from intestinal bacterial flora of the caspian frisian roach (rutilus frisii kutum). a bacteriocin produced by the bacterium bacillus cereus strain rf ...

A 60-days feeding trail was conducted to evaluate the effects of dietary digestible energy levels (DE) on kutum, Rutilus frisii kutum. Four is nitrogenous (35% protein) diets with digestible energy levels of 2500, 2600, 2700 and 2800kcal kg-1 was tested. Two hundred and forty advanced fry (2±0.4g) were randomly distributed in 12 fiberglass tanks of 400L capacity. Nutritional responses in terms ...
