background: copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. fish blood is susceptible to contamination-induced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. methods: in this study, juvenile species of silver carp with average weight of 200gr w...

The relative differentiation of the protein content in green algae grown contours Dengizkul reservoir was due to fact that level mineralization water low at entrances(mouth) lake and high remote from it. Therefore, when growing with a Сhlorella vulgaris Beijer. Scenedesmus obliquus (Turp.) Kütz., most optimal nutrient medium is variant which juice poultry manure mixed 1,2,3 g / l water. recomme...

this study evaluated the antibacterial and antioxidant effects of tamarind water solution on shelf life of silver carp ( hypophthalmicthys molitrix ) fillet during refrigerator storage. treatments of this study were unwashed samples (control), and samples washed with 1% and 2% tamarind water solution. microbial, physicochemical and sensory analysis including total viable count (tvc), peroxide v...

The prevalence of fish-borne zoonotic trematode (FZT) metacercariae was investigated in fish farmed by rural households in Nghe An Province, located in northern Vietnam. In total, 716 fish, including tilapia (Oreochromis niloticus) and 6 carp species, i.e., grass carp (Ctenopharyngodon idellus), bighead carp (Aristichthys nobilis), mrigal (Cirrhinus mrigala), common carp (Cyprinus carpio), silv...

Behavioral responses of silver carp (Hypopthalmichthys molitrix), bighead carp (H. nobilis), and common carp (Cyprinus carpio) to a complex, broadband sound were tested in the absence of visual cues to determine whether these species are negatively phonotaxic and the roles that sound pressure and particle motion might play mediating this response. In a dark featureless square enclosure, groups ...
