Haematological indices of tilapia (Oreochromis niloticus)from Lake Geriyo, Yola, Adamawa State, Nigeri


Author(s): Kefas M, Abubakar K.A, Ja'afaru, A

Abstract: The increases in agricultural activities and rapid urban development which occur along the lake have resulted in serious pollution problems. A toxicological study was carried out to ascertain the effects of aquatic pollutants in the blood of O. niloticus at the Lake Geriyo for a period of eighteen months. The Haematological indices such as Haemoglobin (Hb), Packed cell volume (PCV), Red blood cell (RBC), White blood cell (WBC),Mean corpuscular volume (MCV), Mean corpuscular haemoglobin (MCH), Mean corpuscular haemoglobin content (MCHC) were investigated. The mean value recorded for Haemoglobin were 4.05±0.808 to 10.43±0.817g/dL, PCV ranged from 10.12±0.008 to 24.90±3.266%, RBC ranged from 0.81±0.008 x106/mL to 1.82±0.016 x106/mL,WBC ranged from 108.67±8.206 x103/mL to 238.00±39.171x103/mL, while the MCV were 120.33±7.348 to 167.67±8.525 (fL), MCH ranged from 45.03±8.165 to 63.21±8.165 (pg/cell), MCHC were 28.47±0.327 to50.32±4.090(g/dL). All the haematological parameters shows significant different in variation between months (P<0.05).This study indicates that there was an alteration in haematological profile in O. niloticus blood which may cause biochemical dysfunction in this specie. These results provide a useful tool in monitoring the condition and state of health of fish by knowing the normal value with respect to their responses to stress which affects body metabolism.
