Marked bonefish size ranged 19.5–56.4 cm and recaptured 23.9–49.4 cm. Total abundance for each seine sample and distance between mark and recapture locations were used in two separate multiple stepwise regression analyses. Movement was negatively associated with temperature and predator presence, while sediment coarseness and moon phase were positively associated. Temperature increases were associated withshort-distance movements. Temperature decreases and high-illumination lunar phases were associated with longer-distance movement and likely related to spawning migrations. Presence of predators, like barracuda, was associated with low bonefish abundances and was likely an adaptive response to form multiple schools of low density by bonefish to avoid predation. These spatiotemporal movement and abundance patterns are recommended to be taken into account in fisheries and protected areas management and to inform the decision-making process in urban and tourism development in coastal habitats.
