¹Values are means ± SEM.

²Means within a row not sharing a common superscript are significantly different (p < 0.05) by Tukey contrasts.

³The treatment effect tests whether the response to the salmon differed depending on the amount of salmon consumed. The draw effect tests whether subjects responded to the salmon, regardless of the amounts consumed. The treatment × draw effect tests for a differential response (i.e. dose-response) to the amount of salmon amounts consumed.
