Principal Components for hatchery-produced and wild-caught larval behavior at each stage (n = 648 individuals per stage, or 1,944 individuals total). For PC1 (can be characterized as “inactivity”), hatchery-produced larvae had lower mean estimates of PC1 than did wild-caught larvae at all stages (averaged across trial type) (p < 0.0001). For PC2 (can be characterized as “total distance moved”), hatchery-produced larvae moved greater distance than wild-caught larvae at all stages (p < 0.0001). For PC3 (can be characterized as “zone avoidance”), wild-caught larvae exhibited significantly higher center zone avoidance compared to hatchery-reared larvae at all three stages (averaged across trial type) (p < 0.0001). Whiskers indicate minimum and maximum values, excluding data points (represented by dots) beyond 1.5 x the interquartile range for the upper and lower quartiles. Letters indicate results of Tukey HSD tests conducted for each Principal Component.
