Native fish are species that naturally occur in a specific region or ecosystem without human introduction. They have adapted to their local environment over time, developing unique traits that help them survive and thrive. These fish play essential roles in their ecosystems, contributing to the balance of food webs and maintaining water quality. Conservation of native fish is crucial, as many species face threats from habitat loss, pollution, and invasive species. Efforts to protect native fish often involve restoring habitats, implementing sustainable fishing practices, and raising public awareness about the importance of preserving biodiversity in aquatic ecosystems.
