This study was intended to evaluate growth performance, physicochemical and blood parameters of Oreochromis niloticus for comparing the effects of five test diets, prepared by replacing fish meal by 25%, 50% with microalgae Tetraselmis sp. and Nannochloropsis sp. with feed without replacement. Two hundred seventy Nile tilapia (mean individual weight 0.023±0.0001 g) were randomly allocated into five treatments in triplicate. The fry was raised in 15 rectangular glass aquarium (18 fish/tank within 18 L water) encompassing water holding capacity up to 30L (each). The results revealed that both the supplemented microalgae alone could not significantly enhance the growth performance in compare to control diet (p>0.05). Low palatability and antinutritional factors may be responsible for the poor growth performance. However, significantly higher survival, better TAN, NO2-N and SRP was noticed in T25 than control (p<0.05). The blood parameters exhibited significant increase of certain parameters within reference range, nevertheless significant decrease in some blood parameters was also noticed (p<0.05). Considering the beneficial impacts on water quality, survivality and blood parameters inclusion of microalgae in fish diet can be a better option for fish cultivation.
