Fresh water aquaculture is considered as the most prominent type of aquaculture in the world. Nile tilapia aquaculture is favored because it can adopt to wide range of environments and can tolerate various abiotic stresses. However, the success, profitability of aquaculture and nutritional composition of fishes depends upon nutritional values of meal provided to them. For this purpose, aquafeeds industries are trying to prepare complete meal for favorable nutrition. An experiment was performed to examine the effectiveness of five biochar experimental diets on growth, body composition, hematological and mineral content of Nile tilapia fingerlings. These fingerlings were acclimatized for ten days under laboratory conditions and were fed with commercial diet. After acclimatization 30 fingerlings were distributed randomly in each tank and there were three replicates of each experimental diet. Fingerlings were fed with their respective biochar experimental diet twice a day for 60 days. Data were recorded for growth, body composition, hematological and mineral content attributes. Analysis of data revealed that D3 (CCBC) experimental diet performed exceptionally well for all growth, hematological and mineral attributes of Nile tilapia. D3 caused 44% increase in final weight and provided highest value of SGR (0.96) as compared to controlled. D3 (CCBC) fed fingerlings also showed significant increase in RBC’s, WBC’s, platelates, hemoglobin and PCV. Supplementation of 2% CCBC also provided the maximal absorption efficiency of minerals (Ca, Na, K, Fe and Zn). So form these findings it can be assumed that supplementation of 2% CCBC has the potential to be used as envirnonment friendly, cost effective and sustainable supplement in Nile tilapia diets.
