The effect of ascorbate was examined on the carnitine and lipid metabolism of fish. Young rainbow trout were fed on a single type of moist pellet supplemented with L-ascorbyl-2-monophosphate (AsP) or L-ascorbic acid (AsA) for 60 days and then starved for 60 days. Before and after starvation, As A and carnitine concentrations and lipid content in tissues were determined. Before starvation, long-chain acylcarnitine concentration in the liver was significantly reduced in the ascorbate-free group compared with the AsP-and AsA-supplemented groups. Lipid contents in AsP-and AsA-supplemented groups decreased significantly during starvation but not in the ascorbate-free group: it is considered that the fish whose AsA level was reduced could not consume lipid efficiently as an energy source during starvation. The results strongly suggested the participation of ascorbate in the carnitine and lipid metabolism in fish. AsP as well as AsA could prevent abnormal metabolism of carnitine and lipid, such as reduced long-chain acylcarnitine level and depression of lipid utilization during starvation, by raising the AsA level in the fish body.
