To study the effects of stocking density of Cirrhinus reba (Reba carp) in nursing of spawn for 15 days on growth performance, survival and digestive enzyme’s activities were studied from 7th to 22nd July, 2015. The present experiment was conducted in 20 m3 tanks in triplicate at the College of Fisheries, Lembucherra. Three different treatments @ T1: 3.0; T2: 5.0 and T3: 7.0 lakh spawn ha-1 and fed with 30% protein diet. Significantly (p<0.05) highest mean final weight (0.77±0.00 g), final length (3.74±0.21 cm), survival (55.80±0.81%), protease activity (1.32 units/ mg protein/ min), lowest AFCR (0.57±0.02) and highest APER (5.80±0.17) was found in the in T1 with lowest stocking density (3 million ha-1) in nursery rearing of spawn. There were no significant difference (p>0.05) observed in condition factor, hepato-somatic index and relative fatness. Thus, 3 million spawn ha-1 appear to be most suitable stocking density for nursing of Reba.
