Which outcome decreases swimming efficiency when a fish hyperventilates?

💡 Explanation

Disrupted countercurrent exchange occurs because vigorous ventilation alters water flow, decreasing oxygen extraction efficiency; therefore, fish fatigue and swimming efficiency drops, rather than increasing arterial saturation under normal conditions.
