Abstract Carotenoids are natural pigments commonly found in nature and play an important role in the growth, development, immunity, and body color of animals in aquaculture. The absorption, metabolism, and deposition ability of carotenoids animals in aquaculture is a key target for genetic improvement, which plays an important role in improving their traits. The main types, absorption, and metabolic molecular mechanisms of carotenoids is reviewed tin animals in aquaculture, with a focus on the function analysis of SR-B1, CD36, BCO1, BCO2, CYP2J19 and CYP3A80.The possible mechanisms of carotenoid ketosis and the characteristics of major carotenoid binding proteins are analyzed. Four research aspects are proposed to provide scientific reference for future research on the absorption, metabolism and deposition mechanism, including gene phenotype association analysis to reveal genetic basis, multiomics conjoint analysis to screen and identify new ketolase genes, single-cell RNA (ScRNA) sequencing to analyze carotenoid deposition process, and screening and construction of body color genetic strains.
