Comparative summary of heart rate (fH) responses and recovery among the four capture treatments.

Values represent mean ± standard error. Notes: fH elevation relative to baseline, factorial increase, and fH recovery were assessed for each individual relative to that individual’s unique baseline fH. Factorial increase in fH was calculated by dividing an individual’s peak post-capture heart rate by its pre-capture baseline average. Total excess post-capture heart beats (EPHB) was estimated by integrating the total area under the recovery curve for each fish (to recovery or 24 h in the case of fish that did not return to baseline before being sacrificed at 24 h).1Two-factor ANOVAs (no interaction term) used except for numbers of fish recovering to baseline within 24 h, for which a multiple logistic regression was used.Comparative summary of heart rate (fH) responses and recovery among the four capture treatments.
