Hepatic transcriptome analysis of inter-family variability in flesh n-3 long-chain polyunsaturated fatty acid content in Atlantic salmon

Table 1 Lipid phenotypes of families chosen for molecular analysis

Family	Total Lipid (g/100 g flesh)	n-3 LC-PUFA		ARA
		Relative (μg/mg lipid)	Absolute (mg/100 g flesh)	Relative (μg/mg lipid)	Absolute (mg/100 g flesh)
LL	3.5 ± 0.4	105.1 ± 3.8 *	363.0 ± 30.3	3.45 ± 0.13 *	11.93 ± 1.00
LH	3.5 ± 0.7	133.8 ± 4.8 *	468.0 ± 92.9	4.25 ± 0.06 *	14.87 ± 2.94
HL	5.1 ± 0.8	83.7 ± 14.0 *	426.9 ± 103.2	2.70 ± 0.53	13.81 ± 3.80
HH	5.0 ± 0.7	112.0 ± 7.9 *	554.3 ± 50.7	3.67 ± 0.63	18.04 ± 2.09

Indicated are levels of total lipid (g/100 g flesh, wet weight), and relative and absolute contents of total n-3 LC-PUFA and of the n-6 LC-PUFA arachidonic acid (ARA) in the flesh (n = 3 pools) of the 4 Atlantic salmon families used in the transcriptomic analysis. Asterisks signify significant differences between the two families with the same total lipid content.
