Linear mixed effects model coefficients (β) and standard errors (s.e.) for the natural log of catch-per-unit-effort (CPUE) as a function of categorical fixed effects: foraging mode (FM—solitary versus association) and prey aggregation (PA—single versus school) and an interaction effect between these two. Statistics, t-values and corresponding p-values are given for each variable. *p < 0.05, **p < 0.01, ***p < 0.001.
