Recent Advances in Fish Nutrition: Insights on the Nutritional Implications of Modern Formulations.

The most physiologically relevant n-3 LC-PUFA for fish is docosahexaenoic acid (DHA, 22:6n-3), which plays several essential functions, such as the development of visual and nervous tissue and immunological system modulation, in addition to being highly relevant to human nutrition. Fish nutrition has driven advances in the efficiency, sustainability, and product quality of aquaculture production, facilitating its expansion of aquaculture production [[1]]. The results showed that different temperatures and FO replacement by algal oil did not impair lipid and fatty acid (mainly DHA) digestibility. The authors suggest that n-3 LC-PUFA synthesis was especially modulated by the upregulation of lipid-relevant genes such as elongase 5 ( I elovl5 i ) and fatty acid 6 desaturase.
