Abstract:
A 56-days feeding trial was carried out to evaluate the effects of fish meal (FM) replacement
with black soldier fly meal (BSFM) on growth performance, hepatosomatic index and proximate quality of
whole common carp (Cyprinus carpio). Three experimental diets were made replacing 0% (control
group), 50% and 100% of FM protein by BSFM protein. Each diet was randomly assigned to triplicate
group of total 180 fish (20 fish per tank) with initial weight of 35.2±6.01 g stocked into 250 L tanks. Fish
were fed three times daily to 2.5% of fish biomass. Fish were voluntarily and voraciously feeding on all
diets and the survival was 100%. At the end of the experiment, weight gain (WG), specific growth rate
(SGR), survival rate (SR), feed conversion ratio (FCR), protein efficiency ratio (PER), condition factor (K),
relative gut length (RGL), and hepatosomatic index (HSI) were calculated and found not affected by
dietary replacement of FM with BSFM inclusion level, however, viscero-somatic index (VSI) and final
body length (FL) exhibited significant differences among the experimental groups at p < 0.05. Thus, it is
possible a total replacement of FM with BSFM in common carp diet without any adverse effect on growth
performance and voluntary feed intake
