Which risk increases for freshwater fish when ammonia disrupts the gill's osmotic balance?

💡 Explanation

When ammonia damages gill chloride cells, impaired ion transport affects osmosis because water moves into the fish down the concentration gradient without compensatory ion retention, leading to excessive water absorption by cells. Therefore increased cellular water intake results, rather than mineral loss, oxygen issues or increased ureagenesis, all of which depend on other physiological pathways.
