Which osmotic consequence occurs when a freshwater fish's gills malfunction?

💡 Explanation

Freshwater fish use active transport across gill epithelial cells for osmoregulation; damage causes increased water influx via osmosis because the concentration gradient pulls water in, therefore diluting body fluids rather than efficiently maintaining its salinity.
