Index of diversity, 1-D	0.957	0.950	0.944	0.939	0.0092	0.397	0.214
Number of species accounting for 50% total relative peak height	6.3	5.5	5.0	4.0	1.54	0.608	0.375
Number of species accounting for 70% total relative peak height	14.0	13.5	12.0	10.5	2.65	0.596	0.440

CTR, Control diet; SFL, control diet supplemented with 2% sunflower oil; SFL + fish oil, control diet supplemented with 2% sunflower oil + 1% fish oil; SFL + algae oil, control diet supplemented with 2% sunflower oil + 1% algae oil.

SEM, standard error of the mean.

Contrast CTR vs. OIL: comparison between CTR and all treatments supplemented with oil.
