In the present study effects of different levels of probiotic Pediococcus acidilactici, on growth performance and survival rate of Rutilus kutum fingerlings were investigated. Kutum fingerlings with a mean weight of 1±0.235 g were reared for 8 weeks in 500-l fiberglass tanks (15 fish per tank) with 4 diet treatments (3 replicates for each). Treatments included 1×109, 2:1×109, 3×109 CFU kg-1 dry...

This study was carried out to show the effects of herbal supplement of Sangrovit on the growth parameters, blood biochemical factors, survival and resistance to salinity of the Caspian kutum fry. Fish (1±0.003 g) were divided into four groups fed on diets containing sangrovit at different levels: 0 (control), 0.05, 0.1 and 0.15 % for 45 days. The results showed that there was a significa...

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 ...

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...

Background: Edifenphos, a kind of organophosphate toxins, is used as agricultural fungicides in rice fields. This study was aimed to investigate the effect of temperature on lethal concentration of exposure to edifenphos on Rutilus frisii kutum (Caspian kutum). Methods: The experiment was carried out in static condition and based on instructions of OECD within 10 d under controlled water phy...

To study the effects of post-stripping oocyte ageing at low temperatures on the viability of kutum (Rutilus kutum) oocytes, unfertilised eggs of five females were stored in ovarian fluid at temperatures of 4 and 7 degree centigrade for 24 hours post stripping (HPS). The stored ova of five female kutum were separately fertilised at 0 (i.e., control eggs fertilised prior to storage), 4, 8, 12, 16...

The Caspian kutum, Rutilus kutum Kamenskii, 1901 from Cyprinidae family is native in the Caspian Sea, with the highest distribution in the southern part and rarely seen in the northern and is an economically important species along the Caspian Sea. Despite this, knowledge about stock structure is scarce and there is no formal management strategy to ensure the long-term sustainability of this va...
