Changes of lipid composition and fatty acid content in the hepatopancreas and expression of FABP before and after molting in red claw crayfish (Cherax quadricarinatus)

Abstract

To explore energy utilization during molting stage, matured and juvenile red claw crayfish were selected to determine changes in lipid composition and fatty acid contents of hepatopancreas. Moreover, the expression of the fatty acid binding protein (FABP) gene was determined to verify changes of fatty acids at the molecular level. Results showed that after molting, the crude lipid content was significantly lower than before molting (p
