Comparison of biological variables for northern pike held in two different thermal periods (mid-April and late May - 14 and 17 ◦ C) for either 0, 2 or 6 days in hoop
nets (mean ± S.E.). Baseline concentrations represent separate fish that were angled and immediately blood sampled. Analyses were conducted using two-way ANOVA
with temperature and net set duration as the two independent variables. Italicized statistical output indicates significant models (at ˛ = 0.05). Dissimilar superscript (a,b,c )
indicates significant differences among durations (in the duration column). In the case of interactions, significant differences are denoted by dissimilar superscript only for the
interaction terms.
