Introduction Click to copy section linkSection link copied! The global aquaculture industry is experiencing rapid growth, leading to an increasing demand for sustainable and efficient sources of essential nutritional supplements. Among these, ω-3 polyunsaturated fatty acids (PUFAs), especially docosahexaenoic acid (DHA, 22:6 n-3), and natural carotenoids, such as astaxanthin, have become increasingly vital.

1 Introduction Thraustochytrids are a group of osmoheterotrophic marine protists distinguished by their remarkable biotechnological potential. These microorganisms are renowned for producing diverse enzymes with significant industrial applications and accumulating valuable metabolites like polyunsaturated fatty acids (PUFAs), carotenoids and squalene derivatives (Aasen et al. 2016; Lin et al. 2020). Taxonomically, thraustochytrids have a complex classification history.
