an experiment was conducted to evaluate the effects of biogen probiotic additives on growth performance of common carp, cyprinus carpio. four practical diets containing 0 (control) , 0.1, 0.2 and 0.3 % biogen probiotic were used to feed fish. seventy-two juvenile common carp (65 ? 3.5g) were randomly distributed between 12 fiberglass tanks of 500 l capacity. during 60 days of feeding trial, the...

objective(s): our present study sought to evaluate hepatoprotective and antioxidant effects of methanol extract of azolla microphylla phytochemically synthesized gold nanoparticles (gnap) in acetaminophen (apap) - induced hepatotoxicity of fresh water common carp fish.materials and methods: gnap were prepared by green synthesis method using methanol extract of azolla microphylla.  twenty four f...

this study was conducted to determine the effects of mannan oligosaccharide (mos) on growth, some immune responses and gut lactic acid bacteria of common carp. four experimental diets containing 0%, 0.05%, 0.10% and 0.20% mos were prepared. each diet was randomly allocated to triplicate groups of fish with initial average weight of approximately 14 g. after eight weeks, survival rate was high i...

a 6 week study was conducted to assess the effects of wood betony (wb), stachys lavandulifolia extract on growth performance, hematological and biochemical parameters of common carp, cyprinus carpio. different levels of the wb extract (0, 2, 4 and 8 % weight per weight, w/w, 0wb, 2wb, 4wb and 8wb) in the diet were used. the results showed that final weight and weight gain were significantly imp...

The caryophyllidean tapeworm Atractolytocestus huronensis Anthony, 1958, originally described from the common carp Cyprinus carpio carpio L. from North America, has recently been introduced into Europe (UK, Hungary). In the present study, the dispersion of the tapeworm in other countries of Central Europe (Slovakia and the Czech Republic) is described, including its first observation in the com...

An environmental DNA (eDNA) analysis method has been recently developed to estimate the distribution of aquatic animals by quantifying the number of target DNA copies with quantitative real-time PCR (qPCR). A new quantitative PCR technology, droplet digital PCR (ddPCR), partitions PCR reactions into thousands of droplets and detects the amplification in each droplet, thereby allowing direct qua...

the studies of parasitology was performed on freshwater in farm ponds in isfahan province during the years of 2006- 2008 and in total were fished 150 fish from farm ponds of freshwater fish and dual purpose of agriculture of three regions in isfahan. the fish were 65 cyprinus carpio, 40 hypophthalmichthys molitrix and 45 ctenopharyngodon idella. the samples were taken to laboratory alive and af...

Microcystins produced from cyanobacteria can accumulate in fish tissues. Liquid chromatography coupled with tandem quadrupole mass spectrometry (LC-MS/MS) is an attractive alternative to immunoassays for the determination of low concentrations of microcystins in tissues. Fish taken from Grand Lake St. Marys, a eutrophic lake in Ohio, USA, were analyzed for microcystin-LR in their fillets using ...
