Abstract
The objective of the present study was to evaluate the effect of different dietary α-linolenic acid (ALA, 18:3n-3) to linoleic acid (LA, 18:2n-6) ratios, while employing 100% fish oil deprived diets, on growth performance and flesh fatty acid composition of Murray cod, and subsequent finishing (wash-out) efficiency. The ALA/LA ratios of the five experimental diets were gradually increased from 0.3 to 2.9, with a constant total content of ALA. +. LA of 51%. Fish oil was used for the sixth diet (control), which was also used during the finishing period. It was shown that an increased dietary ALA/LA ratio does not impair growth performance or the tissue lipid concentration of Murray cod. Howeve..
