the aim of this study was to survey levels of polychlorinated biphenyls (pcbs), polychlorinated dibenzofurans (pcdfs), and polychlorinated dibenzo-p-dioxins (pcdds) in white mullet (mugil curema), common snook (centropomus undecimalis), and acoupa weakfish (cynoscion acoupa), collected at sepetiba bay, rio de janeiro, brazil, march-august 2013. pcbs and pcdd/fs were determined by high resolutio...

Salt marshes are under increasing anthropogenic pressures that have been reported to affect the diet of fish (e.g., change in prey composition and availability), eventually resulting alterations their nursery function. Most studies Europe based on gut content analysis, which only reflect a small proportion salt marshes, do not necessarily long-term disturbances. In this study, we investigated i...

The precise detection of genotoxic effects induced by environmental contaminants is an essential part of any genetic toxicology screening programme. Fish, however, provides a sensitive monitor for environmental genotoxicity in aquatic environment. Mugil cephalus genome has now been employed in this study for detection of clastogenic and cellular lesions induced by aquatic contaminants in Abu-Qi...

In the present study, the effects of Chlorella vulgaris on blood and immunological parameters of Caspian salmon (Salmo trutta caspius) before and after exposure to Viral Nervous Necrosis (VNN) virus were examined. In this regard, four treatments in triplicate were chosen. Groups included one control and 3treatments (T1, T2 and T3).  Fish in control group, T1, T2 and T3 were fed diets supplement...

Occurrence and distribution of larval and juvenile fish was investigated in nearshore waters of the southeastern Caspian Sea including the Gorgan Bay. Samples were collected during seven surveys using a fine mesh beach-seine in five sampling sites from July 2014 to June 2015. A total of 15500 individuals mostly juvenile were captured, representing 18 species from 8 families. Most juveniles belo...
