The aim of the present study was to investigate the effect of copper oxide nanoparticles (CuO-NPs) and copper ions (Cu++) on guppy (Poecilia reticulata), in order to assess Cu uptake in the gill, and histopathology of gill and intestinal organs in semi-static regimes for 10 days. Guppy fish were assigned into three groups; one control group, and two experimental groups receiving 20 µg/l of eith...

The effect of acute exposure of four disinfectants commonly used in aquacultural practice (formalin, potassium permanganate, benzalkonium chloride and malachite green) was studied on the histological structure of adult zebrafish (Danio rerio) gills. Groups of 8 individuals were exposed to a dose of each disinfectant corresponding to the therapeutic dose (TD) and five folds of the therapeutic do...
