Which risk results when freshwater fish experience excess hydration?

💡 Explanation

Without constant osmoregulation, osmosis relentlessly drives water into cells via cellular swelling (cytolysis) because fluids are hypertonic relative to surface water; therefore, tissue dysfunction follows rather than neural or respiratory issues that arise from hypoxia.
