freshwater fish

Freshwater fish are aquatic animals that live in rivers, lakes, streams, and ponds with low salt content. They have evolved alongside these environments to tolerate less salinity than marine fish. Freshwater fish play essential roles in ecosystems, maintaining water quality and supporting food webs. They possess adaptations like specialized kidneys that regulate salt balance and body structures suited for navigating their habitats. Examples include trout, bass, and carp. These fish are also important for human activities such as recreation and fisheries, and they require protected habitats to thrive amidst environmental changes.
