Which risk increases for saltwater fish consuming excessive amounts of freshwater due to osmotic pressure imbalances?

💡 Explanation

When saltwater fish consume large amounts of freshwater, dilution of bodily fluids causes hyponatremia because high water influx overwhelms osmoregulation mechanisms, reducing sodium concentration in the blood. Therefore neurological disruption results, rather than protein denaturation, mineral precipitation, or gas embolism which require different physiological conditions.
