Freshwater fishes have remarkable capacity to extract Na+ and CI– through their gills from surrounding water having less than 1 m M/L NaCl, even though the plasma concentration of the salt exceeds 100 m M/L NaCl. Thyroid gland and suprarenal bodies secrete adrenocortical hormones which control osmoregulation in fishes. But in fishes and aquatic animals their gills and oral membranes are permeable both to water and salts in marine environment, salt is more in water against the salt inside the body fluid, hence water moves out due to the process of ‘osmosis’.
