Effect of different ratios of maggot meal (Hermetia illucens) on growth performance and body composition of vannamei shrimp (Litopennaeus vannamei) post larvae

Maggots of Hermetia illucens have a high nutritional value and can partially replace fishmeal in aquaculture feeds. This study aims to determine the effects of different ratios of maggot flour in the feed of post-larvae vannamei shrimp on their growth, feed utilization efficiency, amino acid profile, and fatty acids. 320 vannamei shrimp had an average initial weight of 52 g This study used a completely randomized design (CRD) four treatments and three replications: A - control (no maggot meal); B - replacement of fishmeal with 8% maggot meal; C - replacement of fishmeal with 16% maggot meal; D - replacement of fish meal with 24% maggot meal. The absolute and relative weight growth rates, the total feed consumption, the feed utilization efficiency, the protein efficiency ratio, the survival rate, and the water quality were measured. The substitution of fishmeal with maggot flour significantly affected (p
