Definition
A freshwater fish is any fish that lives in bodies of water with low salinity, such as lakes, rivers, and ponds. Think of them as the chill locals of the aquatic world 😎. Unlike saltwater fish, freshwater fish have adaptations to maintain their internal salt balance in a low-salt environment. Examples include trout, bass, and catfish. They play a crucial role in freshwater ecosystems and provide a source of food for humans and other animals. Their delicate flavors are often prized.
