Results are means ± SEM (n = 3). Different superscript letters within a row denote significant differences between diets as determined by one-way ANOVA with Tukey comparison test (P < .05). CFO, commercial fish and vegetable oil feed; EFO, enhanced fish and vegetable oil feed; TCO, transgenic Camelina oil feed.
