Which outcome occurs when reduced opercular pumping in fish encountering hypoxic conditions?

💡 Explanation

Reduced opercular pumping means less water flow across the gills; therefore, the countercurrent exchange mechanism of oxygen absorption is impaired. This leads to a reduced efficiency in extracting oxygen because the concentration gradient decreases, rather than maintaining optimal levels.
