Which outcome occurs when a saltwater fish experiences prolonged exposure to freshwater?

💡 Explanation

When a saltwater fish is in freshwater, osmosis causes water to flow into the fish's cells because of a lower solute concentration, which leads to cellular swelling, due to passive diffusion. Therefore cell swelling results, rather than ventilation increase, chloride cell activity, or reduced filtration which would require salinity maintenance in saltwater.
