Research progress of substituting fish meal for Black soldier fly in fish immunity enhancement.

Adding immune enhancers to feed can maintain fish health and enhance disease resistance. Some insects contain rich bioactive substances, which can improve the health of fish, among which the Black soldier fly is more studied and applied. Black soldier fly is rich in nutrition, short growth and reproduction cycle, high feed utilization rate, low feeding pollution, and rich in antimicrobial peptides, chitin and lauric acid, which has broad application prospects as an immune booster and health promotion agent in fish culture. In the paper, the biological characteristics and principle of Black soldier fly as immune enhancer are summarized, the application of Black soldier fly in various fish immune enhancer in recent years is summarized, and the appropriate proportion and form of replacing fish meal and other feed ingredients are discussed, to provide reference for the efficient application of Black soldier fly in fish culture.
