Resum:ABSTRACT The present study examined the impacts of Lactococcus lactis D1813, salinity (8 and 25 ppt), and dissolved oxygen (DO) concentrations of 8.5 and 3.5 mg/L on Litopenaeus vannamei muscle and head lipidomic profile. The muscle and head were examined using liquid chromatography‐mass spectrometry (LC–MS/MS) for lipidomic nutrient profiling. The lipidomic profiling revealed the primary nutritional metabolites in L. vannamei muscle and head, which are composed of glycerophospholipids, sphingolipids, sterols, and saturated fatty acids. Huang head had the most glycerophospholipids and sterols, including PC (12:0/18:2), PC (18:0/20:4), PC (16:1/22:6), PC (10:1e/20:4), PC (33:0/18:2), Cer (d14:1/20:0), SM (t18:1/22:4), and SM (d18:0/16:1). Conversely, the T3BS head group had a much greater proportion of sphingolipids and saturated fatty acids, including Cer (d14:1/20:0), SM (t18:1/22:4), SM (d18:0/16:1), SM (d18:1/18:3), and butyric acid, stearic acid, myristic acid, arachidic acid, and lauric acid (p < 0.05). The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis indicated the significant enrichment of glycerophospholipid metabolism, sphingolipid metabolism, glycerolipid metabolism, linolenic acid metabolism, and alpha‐linolenic acid metabolism in T3BS muscle and head. The findings unequivocally demonstrate that the supplement of L. lactis D1813 under 25 ppt salinity and 3.5 mg/L DO levels significantly raises the content of sphingolipids and saturated fatty acids and enriches the metabolic pathways of linolenic acid and alpha‐linolenic acid in L. vannamei. The results indicated that L. lactis D1813 could be used as an effective probiotic to enhance shrimp tolerance and nutritional quality in aquaculture systems under environmental stress conditions. Also, a more desirable lipid profile renders them beneficial to human health, particularly cardiovascular health and brain function. Additional research can be done to assess the therapeutic advantages of L. vannamei‐derived lipids in humans regarding cardiovascular health, cancer, and brain functioning.
