Dietary inclusion of frass from black soldier fly (Hermetia illucens) larvae modulates gut microbiota without compromising the growth performance and health status of catfish (Ictalurus punctatus) juveniles

Frass was included in diets at 0, 1.25, 2.5, and 5%. Channel catfish (Ictalurus punctatus) juveniles were fed for 60 days. After the feeding trial, digesta was collected from the posterior segment and subjected to DNA extraction, followed by sequencing the V3-V4 region of the 16S rRNA gene.
