چکیده
The chronic effect of environmental methomyl on the antioxidant system in testis Nile tilapia (Oreochromis niloticus) and its recovery pattern was investigated. Tilapia were exposed to sublethal concentrations 0.2, 2, 20 200 ?gL?1 for 30 days thereafter moved methomyl-free water 18 days. Antioxidant levels testis, including glutathione peroxidase, catalase, glutathione-S-transferase, reductase, superoxide dismutase, reduced glutathione, oxidized measured every 6 during period exposure, at after being transferred water. results showed that lower concentration (0.2 ?gL?1) had no above antioxidants, thus 0.2 could be seen as NOAEL tilapia. However, higher significantly influence antioxidants. Glutathione peroxidase increased significantly. On contrary, decreased Catalase, glutathione-S-transferase (2 ?gL?1), but (200 ?gL?1). test oxidative damage caused by 2 reversible, irreversible within period.

The effect of mushroom prebiotic (Pleurotus ostreatas) on histopathological changes in liver and gill tissue of Nile tilapia (Oreochromis niloticus) exposure to silver nitrate
The presence of contaminants in aquatic bodies causes stress responses in aquatic animals, especially fish, which ultimately affects the physiological condition of fish and reduces their immune function, so the use of immune stimulants such as prebiotics is essential. The aim of this study was to investigate the effect of different levels of pleurotus ostreatus on the histological characteristi...
متن کاملTol2-mediated transgenesis in tilapia (Oreochromis niloticus).
The Nile tilapia (Oreochromis niloticus) is an important species in aquaculture and an excellent model system for laboratory studies. Functional genetic analysis using this species has been difficult because existing methods for producing transgenics are inefficient. Here we show that the Tol2 transposon system can be used to create transgenic tilapia with high efficiency. We constructed a line...
