The Grass Carp is a large freshwater fish native to East Asia, particularly in the rivers of China. It is known for its ability to consume vast amounts of aquatic vegetation, making it an effective tool for controlling weeds in lakes and ponds. Grass Carp can grow up to 4 feet long and weigh over 100 pounds, and they are often used in fisheries management. This species is part of the family Ctenopharyngodonidae and is commonly found in slow-moving waters. Grass Carp are herbivorous, primarily feeding on grasses and other plant materials. They have been introduced to various regions, including the United States, for biological control of invasive aquatic plants.
