Evaluation of Black soldier fly (Hermetia illucens L.) larvae meal as protein source in diets for juvenile Red drum (Sciaenops ocellatus)

This 8-week study assessed the effects of replacing fishmeal with black soldier fly meal (BSFM) (Hermetia illucens) on Red drum (Sciaenops ocellatus) growth performance, whole-body proximate composition, amino/fatty acid profiles, liver/plasma physio-biochemical parameters, liver/intestines histomorphology and gut microbiota. Diets were formulated to be isonitrogenous and isocaloric replacing Fishmeal at 0% (Control), 25% (BSFM25), 50% (BSFM50), 75% (BSFM75) and 100% (BSFM100) with BSFM.

本试验为期8周，旨在评估以黑水虻幼虫粉（black soldier fly meal, BSFM，学名：Hermetia illucens）替代鱼粉对红鼓鱼（Sciaenops ocellatus）生长性能、全鱼体常规营养组成、氨基酸与脂肪酸组成谱、肝脏及血浆生理生化指标、肝脏与肠道组织形态学以及肠道菌群的影响。试验所配制的饲料均为等氮等能饲料，以BSFM分别替代0%（对照组）、25%（BSFM25组）、50%（BSFM50组）、75%（BSFM75组）与100%（BSFM100组）的鱼粉。
