Comparative Effect Of Crude Oil Products On Nitrogen Content Of Clarias gariepinus Juveniles

Abstract

The comparative effect of crude oil products was investigated using Clarias gariepinus uveniles. The fsh (average weight 100.20 ± 0.08g) was introduced inograded concentratons (2.00, 4.00, 6.00 and 8.00 ml -1) of Bonny light crude oil (BLCO), premium motor spirit (PMS) Dua purpose Kerosene (DPK) in toxic phase that lasted for two hours. Ntrogen level was estimated from both serum and blood of C. gariepinus. Result showedthat there was increase in nitrogen content of fishin the treated samples compared to control experiment. This may be due to the presence of the crude oil. The biological parameter investigated showed significant differences (p<0.05) when compared to the control. Increase nitrogen content suggested that there was an alteration in the water chemistry predisposng the fish to stress and disease.
