FRESHWATER FISH

Freshwater fish are species that live in rivers, lakes, ponds, and streams, where the water contains a low concentration of salts (salinity). Unlike their saltwater counterparts, freshwater fish thrive in environments with less than 1% salinity. They have evolved unique adaptations to survive in these waters, such as specialized kidneys that regulate water balance, allowing them to maintain internal salt levels in an environment where salinity is low.

Freshwater fish come in a diverse range of shapes, sizes, and behaviors. They can be herbivores, carnivores, or omnivores, depending on their diet. Some well-known examples include species like bass, trout, catfish, and goldfish. These fish play an important role in the ecosystem, helping to control insect populations, serve as prey for larger animals, and contribute to the health of the water by influencing nutrient cycling.

Freshwater fish often face threats from human activities, such as pollution, habitat destruction, and overfishing, making conservation efforts critical to maintaining healthy aquatic ecosystems. They are also popular in aquariums and recreational fishing due to their beauty, variety, and adaptability to controlled environments.
