This histogram plot shows Catch Per Unit Effort (CPUE, defined here as number of fish per dive cycle) for shallow and deep simulated dives. For both depth categories the effects are shown separately for low and high prey density. High prey density, shallow dives have the highest CPUE of around 0.14, followed by deep high prey density dives at CPUE of 0.07. Low prey density dives are indistinguishable at CPUE of around 0.035 to 0.045
