Answer: Yes
12) Atlantic striped bass, Morone saxatilis
Atlantic striped Bass can be found in the United States and Canada in fresh and salt water (“Atlantic Striped Bass”). When the temperatures start to become
warmer this species will swim from the salt water into the fresh water allowing them to spawn. Due to climate change they are adapting and starting to migrate sooner. They are able to go from waters of extreme salinity to waters with very little salt because of their kidneys. Their kidneys control a process called osmoregulation. Osmoregulation is the ability to regulate the internal environment compared to the external environment (Palmisano, Aldo). The gills have adapted to where they can release the extra salt from the body when the fish are in the ocean (Palmisano, Aldo). When the fish are living in fresh water environments the gills will help the body retain the available salt and release the water (Palmisano, Aldo). This will help the kidney not have as much work to do which will help the kidney remain healthy.
