High Ratio of Dietary Palmitic Acid to DHA + EPA Induces Glucose Metabolic Disorder Through Endocrine and Transcriptional Regulation in Large Yellow Croaker (Larimichthys crocea).

ABSTRACT: Background/Objectives: Replacing fish oil with vegetable oil is an important measure for aquaculture to relieve the pressure of fish oil, but it is also easy to cause the growth decline and metabolic disorder of farmed animals, mainly due to the change in dietary fatty acids. This study investigated the regulatory effects of dietary fatty acid composition on glucose metabolism in large yellow croaker (Larimichthys crocea) with an initial weight of 30.51 ± 0.16 g. Methods: Three isonitrogenous (~43% crude protein) and isolipid (~11% crude lipid) diets were formulated as follows: control (CON, DHA/EPA-rich oil as primary lipid), moderate palmitic acid (MPA, 50% of DHA+EPA-rich oil was replaced by glyceryl palmitate), and high palmitic acid (HPA, 100% of DHA+EPA-rich oil
