Clinical And Haematological Effect Of Paraquat Dichloride On African Catfish Clarias Gariepinus Juvenile
ABSTRACT
Haematological effects (Hb, PCV, WBC, MCH, MCV, MCHC) of paraquat dichloride on Clarias gariepinus juveniles was studied. 100 Clarias gariepinus juvenile fishes weighing between 102g to 112g with lengths between 19cm and 24.45cm were used. The fishes were exposed to paraquat concentrations of 20 mg/l, 40 mg/l, 80 mg/l, 120 mg/l and 160 mg/l for 96 hours. Clinical manifestations such as erratic swimming, skin discolouration, rapid but short darts, jerky movements and frequent attempts to jump out of the plastic aquaria were observed and these increased as the concentration increased. The result showed a significant reduction (p < 0.05) in Hb at 80 mg/l concentration, and there was also a significant reduction (p < 0.05) in WBC across the groups and these increased as the concentration increased. There was no significant difference (p< 0.05) in RBC, MCH, MCV and MCHC. The use of paraquat should be strongly controlled and carefully monitored to avoid the possible damage to both fish and their aquatic environment.
