How do freshwater and saltwater fish maintain homeostasis?
The key to their problem is osmoregulation – active regulation of the osmotic pressure to maintain the fluid balance and concentration of salts [1]. Let first take a look at freshwater fishes. Because the salt concentration inside their body is higher as in the surrounding water, water enters the body due to osmosis.Click to see…

In this regard, how do saltwater fish maintain homeostasis?Saltwater fish maintain homeostasis by excreting excess salt to maintain a balance of water in high saline conditions.Likewise, how do gills help fish maintain homeostasis? Answer and Explanation: Gills play a significant role in the maintenance of homeostasis in fish. During breathing, fish take in water with their mouth and expel it through their gills. As water passes through the gills oxygen is absorbed and carbon dioxide is exhaled. Also to know, how do freshwater fish regulate salt and water balance? To combat this, freshwater fish have very efficient kidneys that excrete water quickly. They also reabsorb salt from their urine before it is ejected to minimize losses and actively take salt from their environment using special cells in the gills.Why freshwater fish produce dilute urine?To inhabit freshwater, fish had to replace salts lost through diffusion to the water and eliminate excess water absorbed from the environment. Their kidneys produce small volumes of fluid containing high concentrations of salt. Freshwater fish produce large volumes of dilute urine, which is low in salt.
