Urination Like other vertebrates, fish produce waste in the kidneys. But, they also process waste through their skin, and even their gills which release waste as ammonia. Because they live in water, fish have trouble maintaining the water-to-salt ratio in their body. The amount of salt and water coming and going from their body needs to be in harmony or they will die. The way they regulate these ratios depends largely on the excretory system. Water constantly diffuses across the skin membrane and through the gills. Mucus on the fish's body slows diffusion, but is not enough to stop it completely. The amount of salt in the urine varies depending on if the fish is a freshwater or saltwater fish.
