Effect of Silkworm Pupae (Bombyx mori) as a Fishmeal Substitute on the Growth Parameters of Pangasius (Pangasius pangasius) Fingerlings

This study aimed to determine the impact of silkworm pupae (Bombyx mori) as a fishmeal substitute on the growth parameters in Pangasius (Pangasius pangasius) fingerlings. Four treatments (T1, T2, T3 and T4) and one control (C) were set up with different percentages of silkworm pupae concentrations, which were 25, 50, 75, and 100 percent incorporation in basal diet. Each treatment has three replications and 27 percent crude protein diet was given to experimental fishes at the rate of 5 percent of body weight. The results showed significant (p< 0.05) differences in different growth parameters like net weight gain (NWG), percentage weight gain (PWG), specific growth rate (SGR), net length gain (NLG), and feed conversion rate (FCR). The best result was found in treatment T3 and followed by T2, T1, C, and T4. This results in the viability of silkworm pupae as a replacement for fishmeal by T3, T2, and T1. This study will open the doors of new era in feeding management in fisheries sector.
