The present study was carried out on the fingerlings of Nile tilapia (Oreochromis niloticus) to investigate the effect of ‘Guar sprout meal (GSM)’ as a potential protein replacement of fishmeal. The experiment was set in triplicate with five isonitrogenous and isolipidic containing guar sprout meal at an inclusion rate of 0, 25, 50, 75 and 100% respectively. The practical diets were fed to triplicate groups of 20 fingerlings with mean initial body weight 4.26 ± 0.02 g reared in circular FRP tanks of 100 L capacity at 5-7% of their body weight. The results indicated that animals performed well at 25% and 50% inclusion levels of GSM. However, the diet containing 25% GSM interestingly gave higher final weight and specific growth rate compared to other treatments and control diet. It was observed that there was a significant decrease in growth rate, SGR, FCR, PER and feed utilizations with increasing GSM levels beyond 50%. The percentage survival obtained was 100% with all the treatments. The results conclude that GSM at an inclusion at 25-50% can be a promising and economically sustainable source protein and fish meal replacement in the diet of Nile tilapia fingerlings.
