Calculation of metabolic waste of Clarias gariepinus and Tilapia niloticus obtained from two commercial fish ponds in Gwagwalada

An automated blood serum chemistry analytical system designed for human usage was employed to establish the levels of urea and creatinine parameters present in sera obtained from 60 experimental groups of catfish and tilapia from a commercial pond with length ranging from 10 to 58 cm and weight ranging from 98.2 to 900.2 grams (For the first group) and 6.8-5 cm and 28.9-90.5 g (for the second group) respectively. The present study was carried out to determine the result of Urea and Creatinine values of Clarias gariepinus and Tilapia niloticus obtained from two commercial ponds in Gwagwalada. The results observed from catfish when compared to that of tilapia, showed a slight difference of both species. Highest Creatinine value recorded for Clarias gariepinus was 1.53 mg/dl and the lowest was 0.00 mg/dl. While the highest Urea level recorded is 10.4 mg/dl and minimum was 0.04 mg/dl. Highest Creatinine value recorded for Tilapia niloticus was 1.43 mg/dl while the lowest value recorded is 0.02 mg/dl. Urea highest value recorded is 11.40 mg/dl and lowest value is 0.02 mg/dl. The ratio of urea to Creatinine was very high for both species and can be concluded to be either as a result of gastrointestinal bleeding, kidney failure, high protein diet as well as pollution of pond water with substances such as ammonia, and urea which are excreted by fish. It is therefore important to regularly change water to control the effect Urea blood level.
