Chub, exposed to simulated Pulsed Direct Current (PDC) electric fishing operations, exhibited rapid elevations in plasma glucose and blood lactate, but plasma cortisol did not change significantly. These adrenergic disturbances, which persisted for up to 8 h, were greater in exposed fish than in fish which were instead subjected to 5 s emersion and handling stressor.
