Eri silkworm pupae as fish meal replacement in common carp (Cyprinus carpio L.) feed in indoor aquaria

Abstract

Eri silkworm (Samia ricini D.) pupae based fish feed, for common carp (Cyrinus carpio L.) advanced fry, in indoor aquaria was evaluated with eight different diets. Eri silkworm pupae meal (ESWPM) based fish feeds influenced the growth of common carp significantly. Fortnightly growth measurements of the carp in eight treatments showed maximum in ESWPM alone and in ESWPM 100 per cent treatments. The proximate nutrient and amino acid composition varied in the fish feed diets. ESWPM based fish feed recorded significant impact on the carp with reference to its weight gain, specific growth rate, feed conversion ratio, and relative growth rate.
