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...

Since the 1990s, anthropogenic activities have been major direct or indirect threats to structural and functional organization of unique ecosystem Caspian Sea (CS). This study attempts investigate relationships between fish community structure environmental parameters analyze Abundance Biomass Comparison (ABC) in CS. The input data, including catch data by species parameters, were collected fro...

To assess changes of gonad development and sex steroids hormones of R. frisii kutum, broodfish were captured during spawning season 2010 (March-April) and induced intramuscularly with following hormone treatments: single injections of 1 μg kg b.w. LHRH-A2, combination of LHRH-A2 with two dopamine antagonists as follows: 1 μg kg b.w. LHRH-A2 + 5 mg kg-1 b.w. PIM, 1 μg kg b.w. LHRH-A2 + 2.5 mg kg...

The histopathological effects of Linear Alkylbenzene Sulfonate on the gill, liver and kidney tissues of the Caspian kutum, Rutilus frisii kutum were studied. The fish were exposed to three sublethal concentrations of anionic detergent, Linear Alkylbenzene Sulfonate (LAS) for short term intervals (192 h). Gill, liver and kidney samples were collected after 192 h of exposure to LAS and lesions we...

Concentrations of heavy metals were determined in muscles of Kutum (Rutilus frisii kutum) collected from the central part of the southern end of the Caspian Sea during February 2011. Except for silver (Ag) and nickel (Ni) which were below the limits of detection, the average levels of arsenic (As), cadmium (Cd), copper (Co), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), lead (Pb), sele...

mercury is one of the most toxic heavy metal which can enter the human body mainly through consumption of seafood contaminated with mercury. in this study, the human health risk due to consumption of kutum (rutilus frisii kutum), in the caspian sea, were evaluated by measuring the concentration of mercury in muscle samples using atomic absorbtion spectrophotometer (perkin elmer fias-100) and co...
