ABSTRACT
Apparently 100 (one hundred) healthy Clarias gariepinus juveniles which measurement of mean weight and length taken respectively was used for range finding test while 75 (seventy five) was used for definitive test. They were acclimatized in de-chlorinated water (tap water exposed to air for greater than 24 hours) in lOOL capacity plastic bowl for 2 weeks. 5 fishes were kept per container. The result of this research shows the toxic nature of the quicklime on the behavioral, physicochemical parameters, hematological, histological and mortality of Clarias gariepininus juveniles. Physico-chemical Parameter of the research displays that there is significant effect (p
