Saturated lipids are more effective than others in juvenile California yellowtail feeds—Understanding and harnessing LC-PUFA sparing for fish oil replacement

Diet-to-tissue transfer of long-chain polyunsaturated fatty acids (LC-PUFAs) is more efficient when diets contain saturated fatty acid (SFA) or monounsaturated fatty acid (MUFA)-rich alternative lipids. This mechanism, the omega-3 or LC-PUFA “sparing effect”, encourages more efficient metabolism of the limited LC-PUFAs available in terms of their important physiological functions and tissue retention, and the likelihood of successful fish oil...
