Effects Of Acclimation On Haematological Parameters Of Fish EFFECTS OF ACCLIMATION ON HAEMATOLOGICAL PARAMETERS OF Tilapia guineensis (Bleeker, 1862)

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
