The grass carp (Ctenopharyngodon idella) is a large, herbivorous freshwater fish native to East Asia. It has a torpedo-shaped body, silvery scales, and a broad, flat head. Known for its voracious appetite for aquatic vegetation, it plays a vital role in controlling aquatic plant growth in freshwater ecosystems.

The Grass Carp (Ctenopharyngodon idella) is native to the rivers of eastern Asia, particularly the Amur River, which flows through the border between China and Russia. It is also naturally found in the large river systems of China, such as the Yangtze and the Pearl River.

Grass Carp typically inhabit freshwater environments. They are found in large rivers, lakes, and reservoirs with slow-moving or stagnant waters. The species thrives in temperate climates, with water temperatures ranging from 20°C to 30°C (68°F to 86°F) being optimal for growth and reproduction.

Grass Carp are herbivorous fish known for consuming large quantities of aquatic vegetation. This diet allows them to play a role in controlling plant growth in their habitats, which can have significant ecological impacts. They are primarily bottom dwellers but can be found throughout the water column depending on food availability. Their ability to feed on a wide range of plant materials makes them adaptable to various aquatic environments.
