Bacterial indole‐3‐butyric acid promotes fish PUFA synthesis
Marine fish are paradoxically rich in polyunsaturated fatty acids (PUFAs) despite limited endogenous biosynthetic capacity, suggesting a critical contribution from the gut microbiota. Here, we first characterized the gut microbiota of Seriola dumerili, a PUFA‐rich marine fish, functionally enriched in the biosynthesis...
