The black carp is a species of freshwater fish native to East Asia, particularly in the rivers and lakes of China and Vietnam. It is known for its elongated body and can grow up to 4 feet long. Black carp primarily feed on mollusks, making them important for controlling snail populations in their natural habitats. Introduced to other regions, including the United States, black carp have raised concerns as an invasive species. Their ability to reproduce quickly and consume large quantities of native mollusks can disrupt local ecosystems. Efforts are ongoing to manage their populations and prevent further ecological impact.
