N-ethyl-N-nitrosourea (ENU) mutagenesis is a useful approach for genetic improvement of plants, as well as for inducing functional mutants in animal models including mice and zebrafish. In the present study, mature sperm of grass carp (Ctenopharyngodon idellus) were treated with a range of ENU concentrations for 45 min, and then wild-type eggs were fertilized. The results indicated that the pro...
Microplastics (MPs) are of emerging widespread concern, but amount research done in freshwater environments and organisms is scarce compared to that marine environments. Thus, the MPs identification four fish at districts Bac Ninh province were documented, including common carp (Cyprynus carpio), grass (Ctenopharyngodon idella), tilapia (Oreochromis niloticus), red-tilapia sp.). found gastroint...
The present study has carried out to clarify the changes of blood parameters grass carp Ctenopharyngodon idella (Valenciennes, 1844), responding chlorofete effect under laboratory conditions, in presence and absence aquatic plant Ceratophyllum demersum (L.). Three concentrations used during chronic exposure time extended (15days). Blood tests (R. B. Cs., Hb, P.C.V.) were studied for fish expose...
Three fish species (Cyprinus carpio, Ctenopharyngodon idella and Carrassius auratus auratus) were artificially infected with the fungus Saprolegnia parasitica. The infection was done under certain laboratory circumstances represented by a change in temperature (10, 15, 20, 25 30°C) nutrients (normal, decrease increase nutrients) constant pH. statistical analysis of results showed that influence...

Due to the importance of fish consumpotion, their contamination with heavy metals can be a serious threat to food security and public health. In this regard, the aim of this study was investigates the concentration and evaluation of the health hazard of heavy metals) Lead, Chromium, Copper and Zinc( in muscle tissue of Cyprinus carpio and Ctenopharyngodon idella species in Bashar River, Yasuj. ...
This experiment was conducted to evaluate the effect of different levels two commercial prebiotic(Behdam) and probiotic(Moltibehsil) on the growth performance, biochemical parameters of body extract and resistance against the challenge tests of Ctenophryngodon idella for 45 days. This experiment conducted in a completely random design with seven treatments which contain triplicates. Three level...
A study was conducted to determine the growth performance and bioaccumulation and tolerance of metal mixture toxins in five fish species including Labeo rohita, Catla catla, Cirrhina mrigala, Hypophthalmichthys molitrix and Ctenopharyngodon idella separately, under chronic exposure of metal mixture (Fe + Zn + Pb) at sub-lethal concentrations (1/3 of LC50) for 12 weeks period. Moreover, response...
