Abstract EN
The effects of acclimation to captivity on blood composition of Nile tilapia Oreochromis niloticus were investigated.
A total of ninety fish, comprising forty five each of juvenile (mean length 10.22cm ±0.26SD ; mean weight 54.62g ± 6.74SD) and adult (mean length 19.4cm ± 7.21SD ; mean weight 346.22g ± 2041SD) were harvested from a reservoir at African Regional Aquaculture Centre, Aluu, Port Harcourt and acclimated in the experimental tanks for a period of seven days.
Before acclimation significant difference (p < 0.05) were observed between the blood parameters of adult and juvenile fish with the female consistently having higher values than the males in all the parameters.
After acclimation to captivity, there was significant reduction (p<0.05) in the values of hemoglobin (Hb), packed cell volume (PCV), red blood cell (RBC), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), lymphocytes and thrombolytic, while the values of mean corpuscular volume (MCV), white blood cell (WBC), neutrophils (NEUT) and monocytes (MON) increased significantly (p < 0.05).
Results from this study therefore suggest that sex and size have some degree of influence on the blood characteristics of O.
niloticus.
