ABSTRACT
The current study was designed to evaluate the growth, hematology and proximate composition of Nile Tilapia (Oreochromis niloticus) cultured in super intensive Biofloc technology (BFT) and conventional pond culture systems (CPCS).Fish samples (n=5) of the same age (120 days) were collected and analyzed. Results showed significantly (p>0.05) higher growth performance in BFT as compared to CPCS in terms of daily weight gain (DWG), total weight gain (TWG), specific growth rate (SGR), productivity and feed conversion ratio (FCR). Various hematological parameters i.e., white blood cells (WBC), red blood cells (RBC), hemoglobin (Hb), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), platelets (PLT) were found significantly (p ≤ 0.05) higher while the results of proximate analyesis i.e., crude protein (CP), crude fat (CF) and total ash (TA) were found significantly (p ≤ 0.05) lowere in BFT as compared to CPCS. Moerover, the moisture content was observed significantly higher in BFT than CPCS. The survival rate was aproximatly 100% in both culture systems. Overall the current study showed improved growth performance and hematology in BFT while betterproximate composition of Nile tilapia reared in CPCS.
