The 'n-3 LC-PUFA sparing effect' of modified dietary n-3 LC-PUFA content and DHA to EPA ratio in Atlantic salmon smolt
n−3 Long-chain (≥C 20 ) polyunsaturated fatty acids (LC-PUFA) are used extensively by fish via β-oxidationwhen in dietary surplus. Therefore it is of interest to optimize n−3 LC-PUFA deposition in fish via a reductionin β-oxidation which may be induced by manipulation of dietary fatty acids. This st...
