Nanomicelle Silymarin Supplementation Alters Antioxidant Activity and Fatty Acid Profiles in Caspian Trout Larvae

A recent study published in *Scientific Reports* examines how silymarin supplementation—both in its free form and as a nanomicelle—affects the growth, antioxidant capacity, and fatty acid profiles of Caspian trout (*Salmo caspius*) larvae. Researchers compared these two delivery methods to determine their influence on the physiological development and nutritional composition of the fish during their early life stages.

The study involved feeding the larvae diets enriched with varying concentrations of silymarin to observe changes in biological performance. The findings indicate that the nanomicelle formulation improved the bioavailability of the compound, leading to measurable differences in the larvae’s antioxidant enzyme activity compared to those receiving free silymarin. Furthermore, the data show that both forms of supplementation altered the fatty acid composition within the fish tissue, suggesting that the delivery method plays a role in how the larvae process and store these nutrients. The researchers documented these physiological shifts to provide a clearer understanding of how nanotechnological applications in aquaculture feed might impact the health and development of Caspian trout.
