Abstract

The effect of acclimation on blood composition of juvenile and adult sizes of Tilapia guineensis was investigated.  A total of eighty (80) fish, comprising forty each of juvenile and adult sizes were collected from the wild (Buguma Creek) and acclimated in the experimental tanks for a period of seven days.  The pooled data of the results indicated alterations in the blood parameters with significant reduction (p < 0.05) in the values of Haemoglobin (Hb); Packed Cell Volume (PCV); Red Blood Cell (RBC); Mean Corpuscular Haemoglobin Concentration (MCHC) and Platelets while there were significant (P < 0.05) increase were observed in the mean values of Erythrocyte Sedimentation Rate (ESR); White Blood Cell (WBC); Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Volume (MCV), Lymphocytes; Neutrophils and Monocytes. The results of this study thus highlighted the stress to which fish are subjected to during the process acclimation.
