Effect of lethal and sub-lethal concentrations of tobacco (Nicotiana tobaccum) leaf dust extract on weight and hematological changes in Clarias gariepinus (Burchell)
Lethal and sub-lethal bioassays on Clarias gariepinus were conducted to evaluate the toxicity of tobacco (Nicotiana tobaccum) leaf dust on weight gain and haematological indices of Clarias gariepinus (mean weight 10.5±0.70g) in glass aquaria with aeration system. The concentrations used during the l...
