Freshwater Fish: Are They Hypoosmotic Regulators in Osmoregulation Strategies?
Freshwater fish are hyperosmotic compared to their environment. Their bodies have more salts than the water around them. This difference causes water to enter the fish through the mouth, gills, and skin. To maintain water balance, they lose excess water mainly through urination, managing osmotic pressure effectively. To counteract this, freshwater fish actively excrete large … Read more
