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...

This study was conducted to evaluate the antibacterial effect of Carum copticum essential oil (Ajowan EO) against Listeria monocytogenes in fish model system. Ajowan EO chemical composition was determined by gas chromatography/mass spectral analysis and the highest concentration of Carum copticum essential oil without any significant changes on sensory properties of kutum fish (Rutilus frisii k...

The aim of present study was to determine the LC50/96 h value of copper sulfate and determine the growth performance of Caspian Sea kutum) Rutilus frisii kutum (fingerlings during 60-days sub-lethal copper (Cu). After acclimation period to two weeks, for determine the LC50/96 h value, total of 27 aquarium with a capacity of 60 L each stocked with 10 fishes an aquarium. Tunney four aquarium and ...

This study investigated the growth rate, proximate composition, and fatty acid profile in juvenile of kutum Rutilus frisii kutum in different dark-light cycles. Fish were stocked randomly in eighteen 2000-L fiberglass tanks and received six photoperiod regimes: natural photoperiod, 24L (light):0D (day), 16L:8D, 12L:12D, 8L:16D and 0L:24D. Application of continuous dark (0L:24D) and an intermedi...

High dietary nitrate and nitrite intake may increase the risk of gastro-intestinal cancers due to the In vivo formation of carcinogenic chemicals known as N-nitroso compounds. In this study nitrate and nitrite residues in smoked Caspian kutum, Rutilus frisii kutum and mullet, liza auratus in the local markets (considered as batch no. 1, 2 and 3) of north of Iran were determined using Spectropho...

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...

We studied the association between environmental stress and epidermal papillomatosis of roach Rutilus rutilus L. in Finnish waters using a 'matched pairs' design. Populations impacted by industrial and/or sewage effluents were compared to reference populations from pristine sites. We examined both the prevalence (proportion of diseased fish) and intensity (number of scales covered by tumors) of...

Caspian sea is a land–locked brackish water lake where zoologically characterized by various aquatic animals aquatic animals and different commercially important fish species Shariati [15]. The fishes in the Caspian Sea and its watershed areas include 78 species, and 49 subspecies which belong to 16 fish family. The bulk of Caspian Sea fishes are anadromos and the major commercially important f...
