Abstract
The present study evaluates the effect of direct Eri silkworm moult
(cast-off larval skin) as a natural feed on the growth and health of Blue
Gourami (Trichopodus trichopterus). Eri moult, which contains residual
proteins, chitin and essential micronutrients, is traditionally discarded but
may serve as a cost-effective and sustainable feed source for fish. In this
experiment, Blue Gourami fingerlings were provided with direct, unprocessed Eri
moult along with a standard basal diet, and their performance was compared with
a control group receiving only commercial feed. Key growth indicators such as
weight gain, length increment was monitored throughout the study. Health
parameters including survival rate, external appearance, coloration, activity
level and fin condition were also assessed. The results showed that the
inclusion of direct Eri moult enhanced growth performance and improved feed
utilisation efficiency. Fish fed with direct moult displayed better
pigmentation, higher activity and overall improved vitality, suggesting
positive effects on their general health and immunity. The study concludes that
direct Eri moult can be effectively used as a natural supplementary feed for
Blue Gourami, providing an eco-friendly and economical alternative for
sustainable ornamental fish culture.
