Comparing two dietary inclusion levels of insect meals from black soldier fly (Hermetia illucens), cricket (Gryllodes sigillatus), and superworm (Zophobas morio) on the gut microbiota of rainbow trout (Oncorhynchus mykiss)

The aim of this study was to investigate the impact of low and high dietary inclusion levels of black soldier fly (BSF), cricket (CR), and superworm (SW) meals on the gut microbiota of juvenile rainbow trout (Oncorhynchus mykiss). Specifically, we assessed how insect-based diets at 10% and 20% inclusion levels influenced microbial composition and diversity, and examined potential relationships between gut microbiota, metabolic function and fish growth performance.
