Body colour of crustaceans is one of the important factors that affect their commercial value. To evaluate the effect of Haematococcus pluvialis on growth and pigmentations in Macrobrachium dayanum, a completely randomized experimental design was developed with 4 treatments and 3 replicates. Diets with different levels of Haematococcus pluvialis (1, 2, 3 and 4 %) were prepared. The formulated diet without Haematococcus pluvialis served as a control. The different diets were fed to the prawns, Macrobrachium dayanum for 90 days and water quality parameters were measured daily. At the end of the experiment, weight gain, Specific Growth Rate, and Food Conversion Ratio were calculated. The result shows that prawns fed with 4% of Haematococcus pluvialis achieved best performance in , weight gain, Specific Growth Rate, Food Conversion Ratio and pigmentation in Macrobrchium dayanum. While feed with 1% Haematococcus pluvialis showed lower growth, FCR and SGR and less pigmentation. This suggests that the total carotenoids content increased in prawns, with increase in the level of Haematococcus pluvialis supplemented.
