The effects of C&R on bonefish have been previously examined in subtropical regions of The Bahamas. However, it is unclear how these findings relate to larger bonefish, as well as those caught in warmer, tropical environments. Here we examined the effects of C&R on physiological stress and reflex impairment in bonefish in tropical Culebra, Puerto Rico. Bonefish (Albula vulpes; 56.6±5.0cm total length, mean±SE) were angled with spinning or fly fishing gear and either handled entirely in the water without air exposure (n=12) or exposed to air for 2min to simulate an aerial hook removal and admiration period (n=11). Upon capture, bonefish were assessed for the presence of five reflexes and held in floating net pens for 1h prior to phlebotomy for quantification of physiological stress. Blood lactate and pH were correlated with fight time, but linear models showed air exposure and water temperature were better predictors of physiological stress. Compared to previous research using simulated angling events, larger bonefish in warmer water under true angling scenarios had similar physiological stress responses. Two minutes of air exposure caused significant reflex impairment, which is a strong predictor of post release behavioural impairment and mortality risk in this species. Air exposure should be avoided with bonefish, especially with larger fish and at warmer water temperatures to minimize negative impacts and ensure the sustainability of C&R bonefish angling.
