Treatment of Dietary Defatted <i>Hermetia illucens</i> Larvae Meal With Different Doses of γ-Rays: Effects on Growth, Waste Production, Antioxidant Capacity, and Gut Microbiota in <i>Acanthopagrus schlegelii</i>.

ABSTRACT: The response of Acanthopagrus schlegelii to dietary defatted Hermetia illucens larvae (HIL) meal irradiated by γ-rays at various doses was examined. Five test diets containing 80 g/kg crude fat, 420 g/kg crude protein, and 200 g/kg fishmeal were designed. All test diets contained 224 g/kg defatted HIL meal irradiated with γ-rays at a dose of 0 (D0), 5 (D5), 10 (D10), 20 (D20), or 40 kGy (D40). Compared to fish fed diet D0, fish fed diets D5 and D10 exhibited higher values of final body weight, weight gain, retention efficiencies of carbon, nitrogen, and phosphorus, and hepatic total antioxidant capacity, but lower values of feed intake and feed conversion ratio. Opposite trend was observed for these parameters in fish fed diets D20 and D40. No significant differences were obs
