Grass Carp (Ctenopharyngodon idella) is a fast-growing, herbivorous fish commonly used in freshwater aquaculture. Native to East Asia, it is highly valued for its ability to control aquatic vegetation, making it useful in managing ponds and reservoirs. Grass Carp thrive in warm waters and can reach market size within 12–18 months. Known for their mild flavor and lean, white meat, they are popular in many cuisines. They are also favored in polyculture systems with other carp species, enhancing productivity in fish farming.
