Which challenge arises for freshwater teleost fish when environmental mineral concentration declines?

💡 Explanation

Ion loss occurs via diffusion, because osmoregulation normally uses active transport to retain such ions and this fails when the water salinity decreases; therefore diffusion overwhelms the uptake rather than increased sediment or swim bladder instability which are consequences in unrelated settings.
