Targeted fish also displayed a much higher degree of vigilance in fished zones than in protected zones. Fish stopped what they were doing to watch the approaching diver almost twice.as often. in fished zones compared to protected no-take and no-entry zones. No-take
and no-entry zones do generate a strong gradient in predator density opposite to the gradient of human pressure) (Rizzari et al., 2015) which may have counteracting effects on coral trout behavior Thus, the increased vigilance displayed by fish in fished zones is likely indicative of modified behaviour due to human exploitation rather than natural predator densities (see also Jayakody et al., 2008; Januchowski-Hartley et al, 2011).
