Black Soldier Fly Larvae Meal as a Sustainable Fishmeal Substitute for Juvenile Hybrid Grouper: Impacts on Growth, Immunity, and Gut Health by Yan Chen, Wenfeng Li, Minyi Zhong, Jun Ma, Bing Chen, Junming Cao, Jiun-Yan Loh, Hai Huang

“…BSFL10 and BSFL30 groups showed good growth and elevated immune enzyme activity, with significantly higher HIS levels (<i>p</i> < 0.05); the Wf of the BSFL10 group was comparable to the control. However, excessive replacement (BSFL50) led to reduced growth (Wf significantly lower, <i>p</i> < 0.05) and increased oxidative stress, as indicated by higher CAT activity (<i>p</i> < 0.05). …”
