Cumulative survival of swimming performance and exercised groups during IPN challenge. A: The inherent swimming performance of the fish had a significant effect on disease resistance, with the good swimmers showing a higher survival (86.1%) than the poor swimmers (77.6%). B: Fish exercised at constant speeds for 10 weeks showed a trend towards higher disease resistance compared to those subjected to interval training regimes (Medium intensity (M) = 87.1%; High intensity (H) = 84.2%; Control (C) = 82.2%; Short interval (Sint) = 78.2% and Long interval (Lint) = 75.3%) (p = 0.21). *indicates significant difference, Mantel-Cox test; p < 0.05.
