The experiment consisted of five treatments in triplicate. The artificial feed was prepared from De-oiled groundnut cake (49.5%), De-oiled rice bran (49.5%) and 1% of vitamin – mineral mixture. The leaf powder of giloy (Tinospora cordifolia) was incorporated into larval feed at various rates. In treatment T1 (control), no leaf powder was incorporated in the feed. In T2, T3, T4 and T5 leaf powder was mixed at the rate of 0.25%, 0.5%, 0.75% and 1% respectively. One hundred post larvae of Catla catla of uniform size (7.3mm length, 1.5mg weight) were stocked in 5×3=15 tanks. The larvae were fed twice in a day @ equal to the total initial weight of post larvae for first 2 days, 3-4 day: 1.5 times, 5-6 day: 2 times, 7-8 day: 2.5 times, 9-10 day: 3 times, 11-12 day: 3.5 times, 13-14 day: 4 times, 15-17 day: 4.5 times and 18-21 day: 5 times respectively. The water quality parameters were regularly monitored. The survival rate of post larvae in T1, T2, T3, T4 and T5 were recorded as 95.3, 94.3, 97.0, 98.6 and 100% respectively. Post larvae fed with diet incorporated with 1% leaf powder achieved significantly enhanced SGR (6.97), FCR (2.4) and GCE (0.415). The above reaserch revealed that Giloy (Tinospora cordifolia) leaf powder has very good growth promoting potential in raising post larvae of carp. Thus it is recommended that the leaf powder of Giloy (Tinospora cordifolia) could be incorporated in fish feed for enhancing growth and survival of post larvae of carp fishes up to fry stage.ennullThesis
