[ 1 ] - Effects of agro-chemicals on fishes: With reference to changes in circulating biochemical parameters in Clarias gariepinus induced with Paraquat dichloride

The response of Clarias gariepinus to Paraquat dichloride, a herbicide that is in high demand in the fragile Niger Delta ecological zone was investigated. The herbicide had been detected in most of the water bodies in the region. The fishes were exposed to the range of concentrations observed in the field (0, 2, 4, 6 and 8) µg/L for 28 days, conducted under the Organization for Economic Co-oper...

[ 2 ] - Bioaccumulation and Histopathological Alterations in Liver Caused by Endosulfan Toxicity in Oreochromis Niloticus

Objective: The toxic effects of sublethal concentrations of endosulfan on Oreochromis niloticus was examined using bioaccumulation and histopathology studies of the liver as toxicological endpoint. Methods: The Organization for Economic Cooperation and Development #407 recommended static renewal bioassay was employed during the test .The test fish were exposed to sub-lethal concentrat...

[ 3 ] - Depuration Technique of Xenobiotics with Reference to Accumulation and Elimination of Paraquat Dichloride in Clarias Gariepinus

Background: Paraquat dichloride is a highly toxic herbicide which is still used in many developing countries. African cat fish (Clarias gariepinus) is a commercially important species in many countries and was selected assess accumulation and elimination of paraquat dichloride in its tissues. Methods: Groups of ten fish with equal lengths and weights were exposed to varying concentrations of...
