Publication Abstract: 

Specimens of Clarias gariepinus were treated with lethal (70, 75, 80, 85, 90, and 95 mg/L)
and sub-lethal concentrations (8, 12 and 16 mg/L) of uranyl acetate, a low-radiotoxicity uranium salt. The
LC 50 value was registered as 81.45 mg/L. The protein and glycogen concentrations in liver and muscles
were decreased in the fi sh exposed to sub-lethal concentrations. The red blood cell (RBC) and white blood
cell (WBC) counts, haemoglobin (Hb) concentration and haematocrit (Hct) values were decreased. Diff erent
blood indices like mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean
corpuscular haemoglobin concentration (MCHC) were negatively aff ected. Level of plasma glucose was
elevated whereas protein was decreased. The level of calcium concentration (Ca) was declined in the blood
of exposed fi sh whereas magnesium (Mg) remains unchanged. The activity level of glutamic-oxaloacetic
transaminase (GOT) and glutamic-pyruvic transaminase (GPT) was elevated in exposed fi sh. These eff ects
were more pronounced in the last period of exposure and in higher concentrations. Results of the present
study indicate that uranyl acetate has adverse eff ects on Clarias gariepinus and causes changes in the
biochemical and hematological parameters of the fi sh.
