Ecotoxicological impact of sub-lethal concentrations of glyphosate–based herbicide on juvenile Clarias gariepinus
Abstract: The presence of pesticides in both aquatic and terrestrial ecosystems has become an important issue globally. This study determined the possibility of bioaccumulation of glyphosate, the active compound of Roundup pesticides in muscle tissues of juvenile Catfish (Clarias gariepinus), and the effects of exposure on some oxidative stress parameters. Forty fishes were grouped and …
Acute toxicity of glyphosate on Clarias gariepinus fingerlings
Abstract: The effects of glyphosate on mortality rate and behavioural responses of Clarias gariepinus fingerlings were investigated under laboratory conditions for 96 hours exposure period. The lethal concentration (LC50) value of glyphosate on fingerlings of Clarias gariepinus was 0.0018 ml/l for 96 hours of exposure. The regression equation was found to be Y= 9.132 + …
Therapeutic potential of Garcinia kola with reference to the restoration of inhibited acetylcholinesterase activities in induced Clarias gariepinus
Abstract: This study was conducted to assess the antidotal prospect of Garcinia kola seeds extract in restoring the activity of inhibited Acetylcholinesterase. This was done by inducing Clarias gariepinus with the enzyme inhibitor (glyphosate pesticide formulation). The fish divided into six groups were exposed different treatments; the pesticide alone, the G. kola seed extract alone …
Histopathological responses of the gill and liver tissues of Clarias gariepinus fingerlings to herbicide, glyphosate
Abstract: African catfish, Clarias gariepinus fingerlings were exposed to sub lethal concentrations of herbicide, glyphosate (0, 0.05, 0.1%, v/v) over 42 days period. The gills showed marked alterations in the epithelia in response to glyphosate treatment. There was fusion in adjacent secondary lamellae resulting in hyperplasia, with profound oedematous changes, characterised by epithelial detachment. In …
Histopathological changes in the brain tissue of Africa catfish exposure to glyphosate herbicide
Abstract: One hundred and twenty normal post juvenile catfish (Clarias gariepinus) of both sexes with a mean weight of 135.44±1.99 g and mean length of 28.32±0.844 cm were purchased from Osayi farm. They were kept in 60 l aquaria at 27.5±0.4 ◦C, pH 7.3, with 12:12 h photoperiod, well aerated, provided with external filtration and …
