WebTo combat this, marine fish intake more water and they filter out excess salt in their kidneys and gills. Similarly, freshwater is hypotonic to freshwater fish, meaning that water is being pushed into the skin. This is due to a higher concentration of water in the surrounding water. Fish combat this by urinating more frequently. WebFreshwater osmoregulators absorb water through osmosis, so they must expel excess water and replenish ions. Thus, they drink little water, excrete dilute urine, and actively … cipfa contract audit toolkit
