Abstract: The potential use of white leadtree (Leucaena leucocephala Lam.) meal to replace fish meal in diets for Macrobrachium rosenbergii (De Man, 1879) juveniles was assessed in a feeding trial. A total of 750 juveniles (approximately 2.0 cm/individual) were randomly assigned to fifteen tanks. Five iso-nitrogenous diets were formulated by replacing 12.5% (Diet 2), 25.0% (Diet 3), 37.5% (Diet 4) and 50.0% (Diet 5) of fish meal by L. leucocephala meal. A diet without fish meal substitution served as control treatment (Diet 1). The juveniles were fed the experimental diets for 70 days. Results revealed that juveniles fed with Diet 2 exhibited the highest specific growth rate (SGR) (3.62±0.13%) and daily growth rate (DGR) (0.014±0.0017 g day-1) followed by Diets 1 and 3. There was no significant difference (p>0.05) in SGR values among juveniles fed with Diets 1, 2 and 3. Juveniles fed with Diets 4 (3.04±0.14%, 0.008±0.0007 g day-1) and 5 (2.70±0.13%, 0.006±0.0004 g day-1) showed lower SGR and DGR values than those fed with the other diets. Results of the present study indicate that L. leucocephala meal could replace fish meal up to 25% in diets for M. rosenbergii juveniles.
